Abstract

In this review, several aspects of artificial gemstones from glasses have been addressed from

the advantages, the fabrication process, the coloration, their properties and finally the use of

RHA as the glass former for the simulant gemstones. The silica sources for preparation of

glasses were locally obtained from sand and biomass ashes in Thailand. The refractive index,

density and hardness values of the glass gemstones reported in these researches had been

meet the standard of EU-regulation for crystal. The glass gemstones were fabricated in a

variety of colors with some special features such as color changing when exposed under

different light sources. Moreover, glass filled ruby has been studied and optimized their

enhancement condition. The developments of high refractive index lead-free glasses for

gemstone research are also leave non-toxically impact to our environment.

Structure–Properties–Function Relationship of Some Oxide

Catalysts and Photocatalysts

Hadi Nur

Ibnu Sina Institute for Scientific and Industrial Research, Universiti Teknologi Malaysia,

81310 UTM Skudai, Johor, Malaysia

Abstract

In this fast changing time, the development of high performance and conceptually innovative

catalytic processes is crucial for chemical industries. It is generally accepted that

heterogeneous catalysis is an important process in the transformation of energy, which is

considered as an integral part of the solution of today’s and the future’s energy problems.

Here, an attempt will be made to introduce several catalytic reactions in order to design a

better catalyst through chemical design. The catalytic reactions that will be discussed are the

oxidation and acid catalysis, and photocatalysis by solid catalysts. These works are classified

into six classes, namely phase-boundary catalysis, acid catalysis, oxidation catalyst,

bifunctional catalyst, photocatalyst and shape controllable synthesis of solid catalyst-assisted

by the magnetic field. Hopefully, the structure-catalytic properties of these several designs of

the heterogeneous catalytic system may assist in the further search for novel approaches to

heterogeneous catalysis for an environmentally-benign transformation of biomass and

organic compounds. However, the demonstration of the structure–photocatalytic and –

catalytic activities relationship remains a challenge today.

Abstract

The performance of multilayer ceramic chip capacitors (MLCs) and other dielectric

applications was progressing by shrinking the dimensions of the individual components and

packing more components in the same area. Since these electronic devices commonly contain

some metallic conductors (i.e. MLCs internal electrodes) such as Au, Ag or Ni. Hence, the

influence of any possible metallic debris or nanoparticles on the properties of the dielectrics,

thereby affecting the reliability of the high volumetric MLCs and then the whole devices,

might be one of the issues to be taken into consideration upon their further miniaturization.

Here, nanoparticles of gold (AuNPs) reinforced BT ceramics were fabricated by using simple

solid-state/pressureless sintering methods without any binders. Apart from their

environmental friendly, these nanocomposites are expected to synergistically combine the

properties of both the ferroelectric BT and the conductive gold nanoparticle, which could

exhibit dielectric properties that are better than those of pure BT ceramics. By using a

combination of several characterization techniques, the results indicate that using different

sintering temperature or gold nanoparticle amounts to produce the ceramics greatly affect the

dielectric, microstructure and domain switching behavior of the materials.

Photoluminescence of Eu3+

doped on several oxide and

Abstract

The Eu3+

- ions doped on phosphate, silicate and borate glasses were fabricated by

conventional melt quenching technique to study its spectroscopic and luminescence

properties for solid state laser device applications. The characteristic intense red emission

peak at 613 nm corresponding to the 5D0 →

7F2 transition of Eu

3+ ions is being topic of

interest to understand their behavior in different glass samples. Addition of Gd3+

ions as co-

doping with Eu3+

doped glasses leads additional energy levels between ground state of Gd3+

8S7/2 to excited state of

6PJ suggesting as a sensitizer to accommodate more room for other

Ln3+

ions for energy transfer mechanism. Among the rare earth ions, the trivalent europium

(Eu3+

) is an important activator and special for understanding the site symmetry around the

rare-earth and also it provides an additional information of Phonon energy which is vital to

understand their phonon relaxation rates. More over the simple electronic structure with a

non-degenerate 7F0 ground state and intense luminescence from the excited

5D0 state to lower

ground state 7F0 make Eu

3+ ion is the best option for analyzing the interaction of the ion with

the local field effect. Eu3+

ions are special rare-earth as they get populated easily to 7F0 and

7F1 levels above the ground state at room temperature which makes researchers to extensively

study their behavior by eliminating their thermal effects using thermal correction method.

Keywords: Phosphate glass, Silicate glass, Borate glass, Energy transfer, Gd3+

ions, Eu3+

ions.
