ty, Bhubaneswar, 751024, Odisha, India

Abstract

Simple one pot procedure for the conversion of carboxylic acid toketone is described. Various carboxylic acids were converted to thecorresponding ketones in excellent manner in presence of tetra methylsilyl chloride (TMSCl) and organolithium reagents (n-BuLi). Aromatic,heteroaromatic and aliphatic acids are converted to the correspondingketones smoothly under the conditions using n-butyl lithium. In theprocess of converting different carboxylic acids using DCC as activator,we observed the low isolated yield of the desired products as we face aproblem duringpurification of ketone from by product. Hence, we havedeveloped an alternative method to accomplish this transformation,where trimethylsilyl chloride has been used to activate the carboxylicacid. In this process, the by product trimethylsilanol has been removedfrom the ketone easily using usual workup process.

Abstract

Titanate nanotubes (TNTs) were synthesized hydrothermally at 150-160oC andcharacterized by SEM/EDX and TEM. The synthesized TNTs were employed toremove crystal violet (CV) and methylene blue (MB) from synthetic wastewater.Experimental results suggested that 3 g/L dose of TNTs could efficiently remove~95% and ~98% of CV and MB respectively at initial concentrations of 20 g/L and 10g/L at a pH of 6.8±0.2 and at an stirring speed of 520±20 rpm. The exclusion of dyesfrom aqueous media followed two kinds of mechanisms i.e., adsorption in dark andphotodegradation in UV-light. The adsorption process of both the dyes followed thepseudo-second-order reaction model, whereas, for photodegradation it was arbitrary.The rate limiting step of the adsorption process was explained utilizing the diffusionmodel in terms of film diffusion and pore diffusion. The plausible photodegradationmechanism was proposed. Evaluated diffusion co-efficient values suggested that theadsorption process follows neither the pore diffusion nor the film diffusion model.The economy of the exhausted material was understood by turnover study and theresult suggested the gradual suppression of uptaking the solute on TNT surfaces.

Abstract

Electrodeposition of the bimetallic alloys is generally applied to a substrate surface inorder to produce a modified substrate system with enhanced mechanical, magnetic,optical or anticorrosive properties. Co-Cu and Fe-Co alloys, deposited on copper,platinum or silicon substrates, have been presenting great interest due to their possibleuse in data store systems and sensor technology. The above mentioned applicationsare based on the magneto resistance properties presented by these alloys, whichpromotes a great variation of electrical resistance in an external magnetic field.However, these properties can only be observed in a metastable solid solutioncontaining few amounts of cobalt in a copper or iron matrix, enhancing thesegregation of small Co precipitates, forming a granular alloy. Though there are somestudies on the magnetic properties of these alloys but there is still scope to improvethe magnetic properties. The present work therefore reveals the electrodeposition ofCo-Cu and Fe-Co magnetic bimetallic alloys on stainless steel electrode from sulfatebath of metals containing suitable additives at different parameters like pH,concentration, current density and temperature to understand their effect on thedeposited alloy in addition to its improve magnetic property. The electrochemicalkinetics of deposition has been studied by Cyclic Voltammetry. The cathodic currentefficiency and composition of Co-Cu and Fe-Co alloy deposits were studied indifferent parametric conditions. The structure of the deposited alloys wascharacterized by X-ray diffraction technique which confirms the formation of a singlesolid solution phase of the alloy system. The surface morphology and elementalanalysis of the deposits have been characterized by SEM and EDX. The magneticproperties have been assessed from the M-H hysteresis curves obtained from theVSM.

Sasmita Mishra, Santosh Kumar Nathsharma, Krushna Gopal Mishra, Raja KishoreParamguru

Abstract

Among all other deposition techniques, the electroless deposition is considered as themost simple and cost effective autocatalytic process. Any kinds of non metallicsurface can be deposited with metals to improve the desired functional properties. Themetal ions are reduced by the electrons obtained from the oxidation of reducing agenton the catalytic surface in suitable aqueous solution. The present work revealselectroless deposition of nano size silver onto polyurethane catheter to improve itsantibacterial property. The size of deposit is regulated through control of silver metalions concentration and immersion time and also by monitoring the mixed current (im)from electrochemical deposition mechanism. A lower rate of deposition is achievedunder anodic diffusion control mechanism and is effected by lowering the [Ag+] andtime of deposition in the electroless plating bath. The size of the deposit is alsoreduced in the process. The size and morphology of the silver plated polyurethane hasbeen characterized by SEM and XRD. The thermodynamic expressions for Em (mixedpotential) and kinetic expressions for im (mixed current) are derived usingButler-Volmer equation and intersection point of superimposed partial cathodic andanodic partial polarization curves. The kinetic and mechanism of the silver depositionprocess is also investigated. The antibacterial behaviour of electroless depositednanosilver moiety on Polyurethane Catheter (PU) substrate on Pseudomonasaeruginosa was demonstrated using zone inhibition test in this study.

Department Of Chemistry, School of Applied Sciences, KIIT University,Bhubaneswar-751024, Odisha, India

Abstract

An effective process for the conversion of carboxylic acid to ketone has beendiscovered. In this process, carboxylic acid has been activated using p-toluenesulphonyl group. Under the optimized condition, aromatic, aliphatic heteroaromaticcarboxylic acids have been proved to be good substrates for this methodology. Theby-product of this reaction can be removed very easily during work up process. Also,one equivalent of organometallic reagent is sufficient to complete this transformation.The key advantage of this process is the ketone has been accessed from acid using oneequivalent of organometallic reagent.

Abstract

Tetrazoles are essential structural motif in many compounds that are widely used inthe field of medicine, biochemistry, pharmacology, and materials. The first tetrazolesynthesis was reported in 1885. Various methods of synthesis of tetrazole and itsderivatives are already reported in the literature. However in the present work ourmain focus is to use the solvent-free green approach to synthesize tetrazole derivativesusing thiourea precursor. Both symmetrical and unsymmetrical thiourea was used asthe synthetic precursor for the synthesis of tetrazole derivatives. Copper (I) andCs2CO3 are used as catalyst for the condensation reaction. This type of protocol givesaccess to amino-substituted tetrazole and triazoles via oxidative desulfurization oftheir respective procedures followed by intra and intermolecular attack of suitablenucleophiles. Characterization of the synthesized molecule has been done by using IRand NMR spectroscopy. Further confirmation of the molecule using Mass data andSingle-crystal XRD is under progress.

Abstract

The current research study focuses on synthesis of MgO nanoparticles by microwave-assistedcombustion method and the removal of Congo Red (CR) and Trypan blue(TB) dyes from aqueoussolution. The crystallite size of the MgO nanoparticles was calculated to be 18nm from X-Raydiffraction pattern. The sample was further characterized by FTIR, TGA and SEM techniques.Theeffect of operating parameters were on adsorption process like MgO dosage, dye concentration,solution pH, agitation speed and temperature in were examined through batch experiments. It wasfound that, 0.2g of MgO NPs showed maximum removal efficiency of both the dyes (more than 98%),for 25ppm of dye concentration at an acidic pH(3-4). Thermodynamic parameters such as ΔG0, ΔH0

and ΔS0were calculated and the negative values of ΔH0 (-0.028 kJmol-1 for CR and -0.158 kJmol-1forTB) corresponds to an exothermic nature of the adsorption process and the positive values of ΔS0

(0.051 and 0.058 Jmol-1K-1 for CR and TB respectively) show increased randomness of the dye andadsorbent.The study of isotherm models revealed that the Freundlich model better fits to theexperimental equilibrium data than the Langmuir model suggesting heterogeneous surface of thenanoparticles. In addition, adsorption kinetic data followed a pseudo-second-order rate for both thedyes.

Abstract

A facile microwave-assisted combustion method was adopted to synthesize pure ZnO and Mg-dopedZnO nanoparticles (NPs), and characterization of the NPs and the sorption behavior with Congo Red(CR) Azo dye was extensively investigated. The structure, morphology and chemical assay of thesynthesized NPs were studied with respect to the pure and 2% Mg-doped ZnO samples. The X-raydiffraction pattern confirmed the presence of crystalline, cubic phase with fluorite structure of both theNPs. The morphological differences between the pure and Mg-doped ZnO NPs were evaluated byFE-SEM, which revealed that the NPs were in the nanoscale regime with irregular crystallinemorphology having a grain size of ~18–45 nm. N2 adsorption/desorption isotherms measured at−196 °C suggested a Type II structure with limited hysteresis loops, likely due to some interparticleporosity. The BET SSA ZnO NPs obtained was found to be 32m2 g−1, indicating about its potential insorption processes. Batch adsorption study for the removal of CR carried out showed that, theMg-doped NPs showed higher loading efficiency (125 mg・g−1) than the ZnO NPs (25 mg・g−1)counterpart. This was corroborated by the isotherm results in which the CR dye sorption followed aFreundlich Isotherm model for both un doped ZnO and Mg-doped ZnO NPs. The sorption of CR dyefollowed a pseudo-second order kinetics. The negative ΔG° (−31.91 and −109.41 kJ mol−1) showedthe feasibility of the adsorption process. The ΔH° was determined as +13.74 kJ mol−1 and 50.7 kJmol−1 for ZnO NPs and Mg doped-ZnO NPs respectively, confirming the endothermic nature of theadsorption for removing CR dye from the solution.

Abstract

With passage of time, environmental pollution due to the contaminating industrialeffluents has become a global concern. Effluents from the textile and dye industriesinclude coloured dyes having a large amount of suspended organic solids. Again, thesubstantial influence of nanostructures are also growing day by day. Considering that,the rare earth metal oxide, CeO2 nanoparticles have been used for the elimination ofthe toxic azo dyes. A facile green synthesis method was adopted to synthesize pureCeO2 nanoparticles (NPs) and characterization of the NPs and the sorption behaviourwith Reactive Blue (RB) Azo dye was extensively investigated. The X-ray diffractionpattern confirmed the presence of crystalline, cubic phase with fluorite structure of theNPs. The morphological analysis of the pure CeO2 NPs were evaluated by SEM,which revealed that the NPs were in the Nano scale regime with irregular grain size.Batch adsorption study for the removal of Reactive Blue (RB) carried out whichshowed that the CeO2 NPs showed a very high loading efficiency and a removalefficiency of 98%. This was corroborated by the isotherm results in which the RB dyesorption followed a Freundlich Isotherm model for CeO2 NPs. The sorption of RB dyefollowed a pseudo-second order kinetics. The adsorption capacity at differentequilibrium concentrations of the dye solution directed establishment of monolayerand chemisorption occurrences. The antimicrobial studies & it revealed that themaximum zone of inhibition was observed against gram (+ve) positive bacteria athigher concentrations of CeO2 NPs.

AbstractIn consequence of time, the growing demand of population and high industrializationproduces excessive amount of organic contaminations from various sources.Particularly the organic dyes are generally treated as a noxious pollutant in variousfields because they are toxic, mutagenic or carcinogenic in nature. Thereby, itscontamination with the fresh water bodies of environment not only become seriousthreat to the aquatic life but also to the human lives or living organisms. So, theirconcentration needs to be reduced before their discharge into water bodies. In recentyears various techniques or methods are being practiced by the researchers forremoval of dye from industrial effluents including photo catalytic degradation,sonochemical degradation, ozone treatment, micellar enhanced ultra-filtration, ionexchange membranes, electrochemical degradation, integrated chemical–biologicaldegradation, integrated iron (III) photo assisted biological treatment, solarphoto-Fenton and biological processes and Fenton-biological treatment, coagulationand also adsorption. Adsorption is one of the most attracting technologies. Theadsorption process is eco-friendly and the availability of a wide range of adsorbents ishigh. Transition metal oxide nanoparticles as advanced environment and energymaterials require very well adsorption performance to apply in practice. Metal oxidenanoparticles has been attracting a research interest owing to its outstanding physicaland chemical properties for which it was used in various fields like gas sensors,chemical sensors, biosensors, superconductors, photo catalyst, optoelectronic devices,cosmetics etc. Herein, we report for the first time the development of an economicaland sustainable nano manganese metal oxide by sol gel method at 400°C usingAcaciaconcina as a reducing agent and manganese nitrate as fuel. The synthesizedmetal oxides NPs are characterized by different characterizations techniques. Thestructural characterization of the MnO2 are carried out by X-ray powder diffractionspectra which shows that the NPs are crystalline in nature with a crystallite size ofaround 32 nm. The surface morphologies and size of the MnO2 are determined bySEM and TEM images. From the results it shows that the oxides are seems like ofporous coral reefs as found in sea. The photophysical properties of the metal oxidesare carried out using UV-Visible diffused reflectance spectra. The functional groupand bonding between the metal to oxygen has been analyzed using the FT-IR spectra.The influence of reaction temperature was also studied while synthesis to obtaincontrolled particle sized NPs. On increasing the reaction temperature to 900°C Mn3O4

NPs were synthesized which were confirmed by doing the above-mentionedcharacterizations. The successfully synthesized NPs have been applied as anadsorbent material for the adsorption of organic dyes like reactive blue. At the time ofadsorption, the different parameters were varied and their kinetics, isotherms andthermodynamic were also studied are calculated. From the above out comes we have

Abstract

The bioactivity and physical characteristics of CeO2 nanoparticles are dependent to agreat extent on the type of the particle, particle size and defects. Herein, pure CeO2

nanoparticles (NPs) was prepared by using a facile and cost effectivemicrowave-assisted combustion synthesis (MACS). The samples were thoroughlycharacterized by various techniques and tested as anti-cancer therapeutic agent incolon cancer. The structural investigations (X-ray Powder Diffraction) revealed theformation of single phase cubic fluorite-type structure of CeO2 with Fm-3m spacegroup. Morphological analysis (FESEM), demonstrated the aggregation of irregularnanoparticles with grain size ~20-40nm. To have more knowledge on the samplemorphology, TEM and HRTEM images were taken.TEM image showed ceria NPswith squared shape and particle size in 50-95nm range. Furthermore, HR-TEMmicrographs confirmed the crystallinity of the CeO2 sample, which was explored bycalculating the distance between the fringes in the corresponding Fourier transformedimage. The BET specific surface area (SSA) of as synthesized ceria nanoparticles,was observe to be 25m2/g. UV- Vis spectral analysis reveals that the direct band gapof CeO2 nanoparticles is about 2.8eV. It was interesting to observe that, the asprepared NPs exhibit remarkable differential cytotoxicity towards healthy (BHK 121,Baby Hamster Kidney cells) and human colon cancer cells (HCT116). Nuclearfragmentation assay indicated clear DNA fragmentation in HCT116 cells, whereasintact nucleus was observed in normal cells, suggesting ceria induced apoptotic celldeath in colon cancer cells. In sum, MACS generated ceria nanoparticles coulduncover a new approach in cancer therapy.References[1] A.Y. Chow, Nat. Educ. 3 (2010) 7–12.[2] G.S. Dite, A.S. Whittemore, J.A. Knight, E.M. John, R.L.

Abstract

A novel multifunctional nanocomposites based on thermoplastic polyurethane (TPU),emerladine salt form of conductive Polyaniline (PANI) and single wall carbonnanotubes (SWCNT) with very high mechanical, thermal and excellent dielectricproperties has been fabricated successfully using solvent casting technique. Thedispersion pattern of nano wire form of conductive PANI and SWCNT in the TPUmatrix is observed from the field emission scanning electron microscope (FESEM) andthe interconnectivity between the PANI nanowire as well as the SWCNT in theinterface is clearly visualized in FESEM photomicrographs. The interfacial interactionbetween the constituents in terms of hydrogen bonding has been confirmed from theFTIR and Raman spectra. The enhancement in tensile strength at 10 weight percentage(wt%) PANI loading explores the reinforcing nature of PANI on TPU matrix. However,at higher loading level of PANI, the tensile strength deteriorates because of theimmiscibility. The increase in thermal stability of the TPU/PANI blend in comparisonto PANI again confirms the establishment of chemical linkages in the interface. Theeffect of PANI loading and temperature on the dielectric relaxation behavior has beenexplored in a wide range of frequency (1-106 Hz). The easiness in the polarization ofthe dipoles in the emerladine salt moiety of PANI and electronic polarization inSWCNT has been confirmed from the improved value of dielectric permittivity (εʹ). Theconductive channels formed by the PANI and SWCNT phases facilitate the tunnelingand hopping mode of conduction which is reflected in the form of improved ACconductivity (σac) and reduction in impedance (Zʹ and Zʹʹ) value. The substantialimprovement in εʹ and σac of TPU/PANI/SWCNT nanocomposites at ultra low loadinglevel of SWCNT (0.5wt%) in comparison to unfilled TPU/PANI blend is theuniqueness of this study. The effect of temperature on εʹ and σac ensures the negativetemperature coefficient (NTC) behavior of resistance of both the TPU/PANI blend aswell as the TPU/PANI/SWCNT blend nanocomposites.

Abstract

Electrically conductive polymer blends have attracted profound attention as dielectricmaterials. However, achieving isotropic behavior, electrical stability and low currentleakage is still challenging. Here we have synthesized a conductive polymer blend ofPolyaniline (PANI) and Poly (vinylidene fluoride) (PVDF) exhibiting relatively highdielectric permittivity (εʹ) together with low band gap. Ionic liquid (IL) has beenincorporated and the effect of IL in the dielectric properties are explored. Theinterfacial adhesion, morphology and the dielectric polarization of the blends areinvestigated. The electromagnetic shielding effectiveness (EMISE) of the conductiveblends is studied in X-band frequency range. The electrical stability and decrease incurrent loss of the blends has been analyzed through I–V characteristics. The findingsreveal that with increase in PANI loading in the temperature range of 25–100 °C andIL incorporation results in excellent dielectric properties for charge storageapplications. The high efficiency of absorption and low transmission ofelectromagnetic radiation by the conductive blends is the main reason for excellentEMISE possessed by the systems which can be used for shielding applications inelectronics. The increase in electrical stability and decrease in current leakage abilityappear in the form of narrow band gap.

Influence of graphene oxide, temperature and ionic liquid ondielectric relaxation behavior of poly (vinyl alcohol) basednanocomposite

Abstract

Electrically conductive polymer nanocomposites with high dielectric properties have

generated tremendous momentum throughout the world due to their versatile

dielectric applications in research and industrial developments. PVA-GO polymer

nanocomposites were fabricated by solvent casting technique. The effect of variation

in GO loading and temperature on the dielectric relaxation behavior of PVA-GO

polymer nanocomposites with and without 1-Allyl-3-methyl imidazolium chloride

(AMIC) has been studied. The microstructure morphology of the nanocomposites

films have been explored using scanning electron microscopy (SEM). Uniform

dispersion of GO in the nanocomposites is achieved in presence of ionic liquid, which

is confirmed by the high resolution transmission electron microscopic (HRTEM)

microphotographs. The dielectric relaxation characteristics such as permittivity (εʹ),

real and imaginary impedance (Zʹ and Zʹʹ), AC conductivity (σac) of virgin PVA as

well as the PVA-GO nanocomposites have been investigated in the frequency range

of 1Hz - 106 Hz at different filler loading over a wide range of temperatures (25 -

150 °C) for the PVA-GO polymer nanocomposites with and without AMIC ionic

liquid. The εʹ and σac significantly increased with increase in highly polarizable GO

loading and temperature while the impedance decreased. The dielectric properties of

the polymer nanocomposites also enhanced due to the incorporation of the ionic liquid.

The variation of ε′ with filler loading has been explained based on the interfacial

polarization of the GO within a heterogeneous system. The increase in σac and the

decrease in impedance with the incorporation of GO explains the formation of

crosslinked and closely spaced conductive networks in the PVA matrix and due to the

relaxation dynamics of polymer chains at the polymer- filler interface. The Nyquist

plot showing significant decrease in the area under the semicircle with increase in GO

loading level and temperature confirmed the increase in charge storing ability of the

developed polymer nanocomposites.

Abstract

Densities and viscosities of ternary mixtures containing cetyltrimethyl ammoniumbromide (CTAB) in aqueous solution of 1,3-dioxolane have been measured at 5 Kintervals from 298.15 to 313.15 K and at atmospheric pressure. The volumetricproperties of CTAB in water as well as in an organic solvent like 1,3-dioxolane havebeen investigated. Apparent molar volume (Vφ) and viscosity of CTAB weredetermined at T = (298.15-313.15) K and used to estimate standard partial molarvolume (Vφ0 ), standard partial molar isobaric expansivity (Eφ0 ), Helper′s constant((∂2Vφ0 / ∂T2)p).The experimental results of viscosity and density have been analyzedby using Jones-Dole equation and Masson equation. Further the values of constants Aand B of Jones-Dole equation were estimated. The values of constants A and B ofJones-Dole equation have been interpreted in terms of solute-solute and solute-solventinteractions. The standard partial molar volume,Vφ0 at infinite dilution weredetermined from Masson equations. The structure making/breaking capacity of soluteis interpreted with the help of Helper equation. From these values, we can estimate thestructure making or structure breaking nature of the molecule in a given solution. Thepositive value of Helper′s constant (∂2Vφ0 /∂T2)p and the negative value of dB/dTshows that CTAB in studied organic solvent predominantly acts as a structure-maker.

Scattering and propagation of seismic wavesIn elastic media

A.K. Patnaik and S. K. SamalDepartment of Mathematics

Abstract

Study of propagation and scattering of seismic waves through various layers of earth

has, always, been stirring enormous curiosity among researchers to enrich more

insight into earth’s interior construct, explore the existence of mineral reserves lying

underneath and to know the cause and devastation of earth quake. Considering its

relevance and applications, we study the phenomena of diffraction and reflection of

scalar impulsive SH waves generated from an impulsive point source by spherical

cavity embedded in an inhomogeneous medium. Furthermore, we study love type

surface wave propagation in curved layers lying over a curved homogeneous isotropic

half space and in an initially stressed fibre reinforced medium lying over a monoclinic

half space. These problems are analytically formulated into differential equations of

wave motion. The solutions of displacement field of diffraction and reflection are

obtained by taking Laplace and Legendre transforms, using boundary conditions as

required by physical nature of the problems and evaluating the contour integrals

resulted by Legendre inversion by residue and steepest descent methods

asymptotically. These yield diffraction and reflection events in shadow and

illuminated zones respectively. WKB and variable separable methods and required

transformations are used to solve wave equations of love type surface waves. The

numerical results of the solutions are illustrated graphically. Indeed, it is found the

influence of inhomogeneity factor of the medium on the displacement solutions of

diffracted and reflected SH-waves, effect of radii of curvature of curved layers love

type surface waves, initial stress of fibre reinforced medium and anisotropic

parameter of monoclinic half space on the phase velocity of Love waves.

Effect of suction/blowing on heat-absorbing unsteady radiativeCasson fluid crossed a flat porous plate with conjugate heatingand inclined magnetic field

R. Mahato and M. DasDepartment of Mathematics

Abstract

This article studies the effect of suction / blowing, inclined magnetic field, and

chemical reaction on heat- absorbing unsteady radiative Casson fluid crossed a flat

porous plate in porous medium. Further, the mass and heat transfer analysis are

examined under the influence of conjugate mass and heat transfer phenomena at the

boundary. The governing equations of the model viz. the energy, mass transfer, and

momentum are transformed into the non-dimensional form adopting suitable

non-dimensional variables and parameters. The exact analytic solutions of the model

for fluid temperature and concentration are obtained using Laplace transform

technique whilst, the solution for the fluid velocity has been obtained analytically by

using the Laplace transform technique and then inverted numerically with the help of

the INVLAP routine of MATLAB. The expressions for fluid velocity, temperature,

and concentration are obtained and discussed graphically for various physical

parameters influencing the fluid flow model taking into account the case of both

suction and blowing. Further, the solution when the Casson fluid parameter

is also obtained as special cases. Results for the skin friction coefficient,

Sherwood number, and Nusselt number are numerically computed and presented

them in tabular form. An increment for the inclination angle of the magnetic field

enhances the fluid velocity while it has a reverse effect on Skin friction. Increasing

the Schmidt number Sc leads to a reduction in fluid concentration and increasing the

value of thermal radiation accelerates fluid temperature. This fluid flow model has

several industrial applications in the field of chemical, polymer, and medical

sciences, etc.

Computation of a fuzzy linear programming problem

with fuzzy decision variable

Admasu Tadesse, Manoranjan Sahoo and Srikumar AcharyaDepartment of Mathematics

Abstract

A realistic assumption of parameters and decision variables in the existing world is

not precise; we consider both unrestricted coefficients and non-negative decision

variables as a triangular fuzzy number to solve a fuzzy linear programming problem

with fuzzy decision variable. In proposed problem we consider a maximization of

fuzzy linear programming problem with equality constraints. To maximize the

objective function we minimize left spread, maximize the core value and the right

spread value. Fuzzy equality constraints can’t be used directly to solve the proposed

mathematical model. The fuzzy equality is defuzzied and after defuzzification a risk

side which is represented in left hand side of constraints is compared with risk side of

right hand side defuzzification value. We equate the core and right spread values of

each left hand side constraints with the corresponding values of right hand side source

constraints respectively. Similarly we have optimized the objective function by

considering the spreadness of the triangular fuzzy parameter i.e. in a maximized

objective function, risk of obtaining a profit is minimized, core of the objective

function is maximized and finally the possibility of obtaining high profit is also

maximized. This results a multi objective linear programming problem. The resultant

crisp linear programming problem is solved using sequential goal programming

approach. Numerical example is given to illustrate the proposed method.

log-normal distribution. Since the proposed mathematical model is probabilistic, it is

difficult to solve directly. The problem is solved in two steps. In the first step

multi-objective probabilistic fractional programming problem is changed to

equivalent multi-objective fractional programming problem. In the second step

sequential goal programming approach is applied to solve the resulting

multi-objective fractional programming problem. The single objective fractional

Multi-objective linear fractional stochastic transportationproblem

Adane Abebaw Gessesse, R. Mishra and M. M. Acharya

Department of Mathematics

Abstract

In real life, there exists an exchange of goods from some sources to known

destinations through a transportation media. However, at the time of transportation,

there is a need for minimizing more than one objective, which is conflicting and

non-commensurable. Also, distributions will be done by maintaining good

relationships between some parameters. These parameters may happen in the form of

actual /standard transportation cost, shipping cost/preferred route, total

return/investment, etc. Besides, these parameters may not be deterministic. In this

thesis, a mathematical model called multi-objective linear fractional stochastic

transportation problem is proposed for handling such a problem. Uncertainties are

handled using both classical and evolutionary algorithmic techniques. The supply and

demand parameters of the constraints are continuous random variables. In the

classical approaches, initially, the random constraints are transformed into equivalent

deterministic constraints using a chance constraint method. The multi-objective

fractional transportation problem is converted into a multi-objective transportation

problem using an equivalent transformation theorem. On the other hand, the

evolutionary algorithmic method called stochastic simulation-based GA approach

solves the problem without finding its deterministic equivalent. Feasibility regarding

probability constraints is maintained throughout the problem. Different numerical

case studies are modeled for illustration of the model as well as the methodology.

integrals and their respective order of convergency has been determined. A numerical

scheme has been developed for the numerical computation of the Cauchy type

oscillatory integral. The scheme is the composition of quadrature rule meant for the

approximate evaluation of Cauchy principal value of the singular integral and a quasi

exact quadrature meant for the numerical integration of Fylon type integrals. The

error bounds are determined and the scheme numerically verified by some standard

test integrals. The solution of the hyper singular integral equation is derived by using

two methods. The first is based on reducing it to a pair of Abel integrals. The second

is based on expansion of the unknown function in terms of Chebyshev polynomials.

Bimodal character of cyclone climatology in the bay of bengalmodulated by monsoon seasonal cycle

Kanak Lata XalxoDepartment of Mathematics

Abstract

The causes of different annual cycle of Tropical cyclone (TC) frequency over the Bayof Bengal (BoB) were investigated through the diagnosis of a genesis potential index(GPI) with the use of NCEP Reanalysis dataset covering 1981-2009. The relativecontributions of four environmental parameters were assessed quantitatively. Thestudy indicated that the strong vertical shear alone from boreal spring to summercannot overcome the relative humidity effect .It is the combine effect of vertical shear,vorticity, and sea surface temperature (SST) that leads to the GPI minimum in borealsummer. It is observed that TC frequency in October-November is higher than that inApril-May which is primarily attributed to the differences of mean relative humiditybetween the two periods. In contrast, more super cyclones (category 4 or above) occurin April-May than in October-November. The study suggested, greater ocean heatcontent, the first branch of northward-propagating intraseasonal oscillations (ISOs)associated with the monsoon onset over the BoB, and stronger ISO intensity inApril-May are favorable environmental conditions for cyclone intensification.

Colossal dielectric and relaxor nature of bi modified ccto thin film

A. K. Mishra M.Devi, Manas R. Panigrahi

AbstractBismuth modified CCTO ceramic thin film is deposited on ITO by modified sol-gelroute. The prepared film is subjected to X-Ray diffraction which shows the cubicperovskite structure. The Scanning Electron Microscope (SEM) micrographs showrandomly oriented and dense rod like microstructure.. The dielectric constant of thefilm is measured in the frequency range 100Hz- 1MHz with variation in temperaturefrom 100-600 K. It is observed that with increasing frequency dielectric constantdecreases and the rate of decrease of dielectric constant with frequencies increaseswith increasing temperature. This may be due to the easy formation of asymmetriccovalent bonds with oxygen ion by Bi3+, which increases the polarizability ofelectronic displacement. It is also observed that the dielectric loss decreases withincreasing frequency. As the temperature increases, the dielectric loss also increasesat low frequency regions. The typical relaxor behaviour of the material is confirmedby peaks broadening at low frequency with increasing temperature and the peaks shiftto low frequency region with decreasing temperature. This relaxation behaviour arisesdue to space charge polarization. The broad band spectrum of high dielectric constantis also seen over the studied temperature range.

Abstract

Currently, the rapid industrialization has brought hazardous dye pollutants into thewater. This is a serious threat to environment. In recent years, interest inphotocatalysis has focused on the use of metal oxide semiconductor materials asphotocatalysts for the removal of dyes. Zinc oxide (ZnO) is an II–VI compoundsemiconductor, having properties like direct band gap (Eg~3.3 eV) and largeexcitation binding energy (~60meV at room temperature). Many works have beenreported on use of commercial ZnO nanoparticles for photocatalysis reaction.However, in all these works the ZnO nanoparticles used are generally of ACSor reagent grades which are quite expensive. For reduction of the cost, in this workZnO nanoparticles are prepared from commercial laboratory grade ZnO powder andcharacterized by XRD, TEM, PL studies. UV photocatalytic dye decomposition studywas done using these ZnO nanoparticles. Particularly, the reaction kinetics andreaction rate are estimated by monitoring various dye decomposition activity. Thephotocatalysis studies with scavengers are done to find the mechanism of thephotocatalytic decomposition process. The performance of these nanoparticles iscompared with respect to benchmark commercial TiO2 nanoparticles (Degussa P25).Artificial visible light and solar photocatalytic dye decomposition have also beenstudied.

Abstract

Polycrystalline samples of Ba0.5Sr0.5Ti O3 with Stannic Oxide (with 1%,3%,5%and7% doping) were prepared from high purity ingredients using a high-temperaturesolid-state reaction technique in a suitable stoichiometry ratio with BaCO3, SrCO3,TiO2 and SnO2 as raw materials. XRD study confirms single phase compound wellagreed with cubic parameters using standard software POWD. The SEM pictureshow clear grain and grain boundaries. As variable dielectric constant and high losstangent create hindrance for tunable devices, this work aims at obtaining a stablebehavior of dielectric constant over ambient temperature and frequency band.Significant modification in the permittivity and loss tangent of BST of different Sndoped ratios was observed over a range of frequency 1kHz to 1 MHz. Compleximpedance spectroscopy of the samples at different temperatures indicated NonDebye type of relaxation. The AC/DC conductivity spectra derived for the differentcompositions explained clearly about the electrical processes and mechanisminvolved in the synthesized materials. Comparatively stable behavior of dielectricconstant over ambient temperature and frequency band of some sample(5% Sn doped)as well as moderate value of loss tangent (of the order 0.02) held promise forapplication in tuned circuits.

Abstract

Pyroelectricity is the property of certain materials. It is explained as the ability ofcertain materials to generate a momentary voltage if they are heated or cooled. Thechange in temperature modifies the position of the atoms in the crystal structure, sothat polarization of the material changes. This polarization gives rise to a voltageacross the material.The binary nitrides GaN, InN, AlN and their alloys are verypromising candidates for high power and high frequency applications due to theirtuneable band gap, elevated thermal stability, large mechanical hardness, largedielectric constant, high electron velocity, large breakdown electric field and highresistance to harsh environment. They can be used for violet, blue and green lightemitting devices and for high electron mobility transistors at high temperature. Animportant feature of heterostructures made from these nitrides is the existence ofpolarization charges at the hetero-interface due to spontaneous and piezoelectricpolarization. This polarization generates an electric field which radically influencesthe distribution and mobility of carriers. They have deep impact on optical, thermaland electrical properties of the heterostructures. As III–nitrides are used in hightemperature and high power operations, the change in temperature in the materialinfluences directly the polarization mechanism. Thus, it is required to explore whathappens to the polarization mechanism under heating; and how it influences theperformance of the devices fabricated from III-V nitrides. In this work, pyroelectriceffect and thermal properties of binaries nitrides (AlN, GaN and InN) have beeninvestigated taking into consideration of built-in-polarization field.

Abstract

Chromium and Cobalt doped BiFeO3 (BFO) nanoparticles were synthesized by afacile sol-gel route. XRD confirmed the phase pure formation of pristine BFO, 1%and 3% Cr-doped BFO and all Co-doped BFO nanoparticles. However, slightimpurity phase appeared in 5% and 7% Cr-doped samples.The crystallite sizes asdetermined by Scherrer equation were found to be 46 nm, 44 nm, 39 nm, 37 nm and34 nm respectively for pure BiFeO3 , 1% , 3%, 5% and 7% Cr doped BFOrespectively whereas 50 nm, 48 nm, 45 nm and 43 nm for 1%, 3%, 5% and 7% Cobaltdoped BFO respectively. The phase purity and stoichiometry of all samples wereconfirmed from EDX, no other elements were observed other than Bi, Fe, Cr, Co andO. From X-ray photoelectron spectroscopy (XPS), it was observed that the valencestate of Fe in Cr-doped BFO and Co-doped BFO was +3. The valence state of Co incobalt doped BFO was found to be +3 by XPS analysis. Mössbauer study alsoconfirmed that the oxidation state of Fe in Cr and Co doped bismuth ferrite samples isof the order of +3 high spin states. The magnetic hysteresis loop measured at roomtemperature exhibited a weak ferromagnetic behavior of the samples and themagnetization was enhanced with the increase in Cr and Co doping concentration.Saturation magnetization increases and coercive field decreases with the increase inCr and Co doping concentration. BFO with 1% Cr doped posseses a higher remnantpolarization and coercive electric field as compared to other Cr doped and pure BFOnanoparticles whereas BFO with.5% Co doped posseses a higher remnant polarizationand coercive electric field as compared to other Co doped and pure BFO nanoparticles.Dielectric constant is decreased by increasing frequency range. Absorption spectra isrecorded in the UV visible range of electromagnetic spectrum and band gap energy iscalculated by Tauc Equation and first derivative of absorption spectra. Band gapenergy is enhanced by the substitution of Chromium and cobalt in Fe site of BismuthFerrite.The above synthesized material shows multiferroic properties and is quitefavourable for data storage application.

Abstract

Locally collected mature bamboo stems were carbonized at 6000C-7000C for 2hoursfollowed by ball milling of the chars for 10 hrs. AC conductivity and dielectricbehavior of as obtained bamboo charcoal samples were analyzed by X-ray diffractionand subsequently by an LCR meter at radio wave frequencies (1Hz- 1MHz). XRDanalysis proves presence of amorphous peaks at 2θ = 240 and 220 attributed to the(002) network of amorphous carbon structures. The dielectric response shows strongfrequency dependence in the 1Hz to 1MHz range exhibiting typical dielectricrelaxation at higher frequencies. Thus bamboo charcoal obtained from abundantlyavailable, renewable bamboo biomass sources can be a potential low cost precursorfor obtaining suitable dielectric materials for energy storage applications.

Abstract

In recent decades, metal nanostructures have attracted increasing interest due to theirshape- and size-dependent optical properties based on surface plasmon resonance(SPR) in a wide range of fields. Thus, a number of studies on synthesis and SPRproperties of gold or silver nanoparticles in a variety of shapes such as nanorod,nanoprism, nanoplate and nanocube have been reported so far from the viewpoints offundamental understanding of their shape-dependent SPR and SPR-based applicationsincluding catalysis, chemical and biochemical sensing, optical labeling, fluorescenceenhancement, and surface enhanced Raman scattering. Here, we have synthesizedhollow silver nanocubes, nanoshells, and nanopyramid for tunable SPR. As-preparedHAgNCs have been used solely to understand the dynamics of plasmonicphotocatalysis over the entire visible range which can change because of the variationin size, shape, and structure of the nanocrystals. By subtle tuning of SPR peak andmolar extinction coefficient, the hollow nanostructures can be made to harvest mostof the solar energies through the processes such as plasmonic photocatalysis.

Abstract

In this revolutionizing era of electronic and electrical devices, the ceramic capacitorswith high dielectric constants and energy storage capacity have a major contributionto the development of efficient method for the storage and distribution of theelectrical power. Due to faster charge-discharge rates (order of nano second) andhigher power density (up to 108 W/kg), they satisfy the requirement of super highpower electronics and systems. However, the current technology is facing challengesto develop a reliable, high temperature (>> 200 °C) and high capacitance ceramicmaterial to be used in a plethora of applications where electronics is exposed to hightemperatures, such as deep oil drilling, aviation, space exploration, automobiles,nuclear reactors etc. There are two major concerns that need to be addressed-temperature stable (i) permittivity and (ii) high energy storage efficiency with a broadworking range. Na0.5Bi0.5TiO3 based compositions with high Curie temperature,diffused dielectric peak and; high ᧭ٺ�� and low �� have proved to potentialcapacitor/energy storage materials in recent times. In spite such attractive properties,few compositions such as NBT-BT, NBT-BKT-KNN, NBT-BT-NN, NBT-BT-NBN,NBT-SBT-NN etc have been investigated so far. A rigorous research in this directionmay bring a revolution in the performance of this family of ceramics.

School of Applied Sciences, KIIT University

Abstract

Structural, morphological, and dielectric properties of bamboo charcoal as afunctional biomaterial bears a lot of importance because of its' abundance,renewability, non toxicity, sustainability, biocompatibility, easy processing and lowcost. Bamboo charcoal samples were prepared from five year old mature bamboostems collected from local forest division, by carbonization method in a tube furnaceat temperatures ranging from 400 oC to 700 oC, in nitrogen atmosphere, with a heatingrate of 100/min for 2 hrs followed by manual grinding in a mortar and pestle.

Structural characterization has been performed using X-ray diffraction (XRD) andfield emission scanning electron microscopy (FESEM). From XRD diffractionpattern, amorphous nature of bamboo charcoal with 002 and 100/101 reflections wereobserved. FESEM analyses show honeycomb like porous structure with differentpore sizes.

Bamboo charcoal samples were pelletized and their dielectric constant, dielectric lossand ac conductivity were measured using LCR meter in the frequency range1Hz-1MHz. The dielectric constant and dielectric loss decreased with increase infrequency up to 100Hz and then saturated. This decrease was low at low and mediumfrequencies, and very high at high frequencies, may be due to interfacial polarizationtaking place in the material. Dielectric constant, dielectric loss and ac conductivityvalue at 1KHz was estimated as 56 F/m, 31, 10-4 - 10-7S/m respectively. Due to highdielectric constant and low loss as compared to the other carbon materials it can beused as a promising material for energy storage applications.

Abstract

In the present time, perovskite solar cells have a great scientific and technical interestbecause of its tremendous potential in harnessing solar energy to produceunconventional green energy. Perovskite materials have high carrier mobility andlong diffusion lengths, which make it an exception as a light harvester material. Alongwith remarkable properties, metal halide perovskites are easy to synthesize and costefficient. Due to the absorption onset of less than 800 nm in the solar spectrum,organo-lead halide perovskite act as a great light harvester. Due to its high absorptioncoefficient, it is crucial for photovoltaic applications. In our work, we have firstsynthesized perovskite i.e. methylammonium lead iodide (CH3NH3PbI3) powder usingwet chemical synthesis. Then CH3NH3PbI3 thin films were deposited on glasssubstrates using doctor-blade and spin-coating methods. A brief characterization studyof both the CH3NH3PbI3 powder and films were done. The compositional andstructural analysis of the CH3NH3PbI3 powder has been characterized using ED-XRFand XRD and the optical and electrical properties were also studied using UV-VISspectrophotometer and Hall Effect measurement system respectively. Thecharacterization result indicates a basic compositional difference between the powderand films due to the involvement of solvent during deposition of films. Also asystematic study was done to understand the stability of fabricated perovskite thinfilm layer. Four different samples were characterized as: (i) As prepared, (ii) 15 daysafter synthesis, (iii) 30 days after synthesis, and (iv) Annealed sample. Thecharacterization result shows that with course of time, the degradation of sample andchange in its properties are observed.

Abstract

Zinc oxide (ZnO) thin films have been studied widely because of their specialchemical and physical properties such as optical transparency, electrical conductivity,piezoelectricity, low cost and chemical stability, large excitonic band energy, goodchemical and thermal stability, high availability in nature and nontoxicity. Thesefeatures have made ZnO thin films very attractive for different applications such asgas sensors, transducers, solar cells, luminescent materials, transparent conductors,heat mirrors, and semiconductor heterojunctions. Now-a-days, various methods havebeen used for the synthesis of ZnO thin films such as pulsed-laser deposition, RFmagnetron sputtering, chemical vapor deposition, spray pyrolysis, chemical bathdeposition and the sol–gel process. In all these conventional works Zn acetate, ZnNitrate or Zn Chloride etc. are taken as precursors. Recently it has been demonstratedthat a non-conventional method can be adopted to grow metal oxide thin film from itspowder precursor. This has been demonstrated for growth of TiO2 thin film. In thepresent work, ZnO thin films were prepared successfully using a similarunconventional method on glass substrates. The prepared films were annealed attemperatures 250oC, 500oC and 750oC. The Optical microscope images have shownthat the thin films have a good uniformity. The average thickness of the thin films asmeasured by gravimetry technique method was 689 nm. A processing parameterdependent electrical behaviour has been observed.
