Welcome to ACCMS-8 We are pleased to announce that the 8th Conference of Asian Consortium on Computational Materials Science (ACCMS-8) will be held at the National Taiwan University of Science and Technology (NTUST), Taipei, Taiwan on June 16-18, 2015. ACCMS was established in 2000 to nurture and promote research and development activities in computational materials in Asian countries. The first Asian Consortium on Computational Materials Science (ACCMS-1) was successfully held in Bangalore, India in 2001. Then, the meeting was held in Russia (Novosibirsk, ACCMS-2 2004), China (Beijing, ACCMS-3 2005), Korea (Seoul, ACCMS-4 2007), Vietnam (Hanoi, ACCMS-5 2009), Singapore (ACCMS-6 2011), and Thailand (Nakhon Ratchasima, ACCMS-7 2013). In the last ACCMS-7, more than 240 participants from 24 countries enjoyed academic discussions and nature circumstances in Thailand. ACCMS-8 will continue the tradition of ACCMS. In ACCMS-8, computational physicists, chemists and material scientists will gather to discuss important issues and to share essential progresses in various fields such as biotechnology, catalysis, spintronics, electron transport, thermoelectric effect, energy applications, and etc. We hope that you will take the opportunity to network with new acquaintances, and to build upon those relationships that have already been established. We look forward to welcoming our friends and colleagues from Asia, as well as other parts of the world. Sincerely yours, Professor Jyh-Chiang Jiang, NTUST Dr. Jer-Lai Kuo, IAMS, Academia Sinica 1

The results show that, on the clean surface, the gas-phase hydrogen atom and SiH3 radicals effectively adsorb on the top sites, while SiH and SiH2 prefer the bridge sites of the first layer. Another possibility for SiH is to reside on the hollow siteswithatriple-bondconfiguration.ForpartiallyH-coverdSi(100)surface,themechanismis similarbutwithhigheradsorptionenergiesinmostcases.Thissuggeststhatthesurfacespecies become more stable in the presence of surface hydrogens. The minimum energy paths (MEPs) for the adsorption/migration and reactions of H/SiHX species on the surfaces are explored using the climbing image-nudgedelasticband(CI-NEB)method.ThecompetitivesurfaceprocessesforSithin-film formation from SiHX precursors are also predicted. The study reveals that the migrations of hydrogen adatoms are unimportant with respect to leaving open surface sites because of their excessively high barriers.Alternatively,theabstractionsofhydrogenadatomsbyH/SiHXradicalsaremore energetically favorable.Similarly,the removalsofhydrogenatomsfromadsorbedSiHX,essential steps for forming Si layers, are dominated by the abstractions rather than decomposition processes. The kinetic analysis, using our home-made SurfKin code [1], is also carried out for such processes at realplasma-enhanceddepositiontemperatures,i.e.,inarangeof300-600K.Accordingly,the followingcompetitivechannelsareconsidered,namely,abstractionofsurfacehydrogensagainst hydrogenmigrations,andhydrogenabstractionsfromadsorbedspeciesagainsthydrogen decompositions. It is concluded that the abstraction channels play an important role in the formation of sillicon thin films. [1] Le, T. N., Liu, B. & Huynh, L. K., J. Comput.

ThecubicmodelofLDAicecontaining512rigidwatermoleculeswas constructedandstudied.CalculationswereperformedusingamodifiedSPC/E potential. The intermolecular interaction was described by the Coulomb interaction (long-range interaction) and the van-der-Waals forces (short-range interaction). The most energetically favorable structure of LDA ice was found using combination of moleculardynamicsmethodandconjugategradientmethod.Inthisstudythe approach [1], which considers the model cell as a unit cell of the pseudo-crystal. The periodic boundary conditions also was applied to the model cell. Using this approach and lattice dynamics method the dynamical characteristics and dispersion curves of LDA ice structure were calculated along the pseudo Brillouin zone.Theresultsofsimulationworkrevealverygoodagreementofvibrational density of states datawith experimental data [2] of Boson peak research inLDA, LDA ice and ice Ih. We show that the main contribution to the excess low-frequency vibrations is given by delocalized (crystal-like) collective translational vibrations. The instantaneousdisplacementvectorsofthesevibrationsofwatermoleculesexhibit crystallineopticvibrationproperties.Theresearchofoxygen-oxygenradial distribution function shows that the nature of boson peak in LDA ice is determined by the hydrogen bond network.

However, it exhibits many phenomena[2, 3] originating from the complex proton dynamics, of which XRD provides very little information.TheneutrondiffractionpatternofD2Oicewasrecentlymeasuredat pressures up to 52 GPa by Guthrie et al. [4], who proposed an octahedral interstitial protonmodel for ice at pressures above 13 GPa to account for the deviation of the neutron diffraction pattern from that of ice VII. In this talk, the interstitial model is theoretically and experimentally re-examined in terms of the interstitial occupancy andX-rayRamanspectroscopy(XRS)spectra[5,6].Theinterstitialoccupancy calculated using first-principles molecular dynamics simulations was negligibly small compared to that of the interstitial model. The oxygen K-edge spectra calculated for theinterstitialmodelexhibitedtwoadditionallow-energypeaksoriginatingfrom watermoleculesandhydroxidesthatareinteractingwithinterstitialprotons, respectively, whereas the experimentally measured spectra did not show these low-energy peaks. These results suggest that the interstitial model cannot explain the XRS spectraoficeatpressuresabove13GPaandthatmoreprecisestructure measurements and analyses[7] are necessary to reveal the peculiar nature[8] of the pressure-induced transition.

Further CVM calculation at finite temperature clarified the effect of the D03 ordering on the recovery of elastic properties at Si concentrations being over 11at.%. Regard the Si concentration of 9-11at.% where the elastic properties decrease sharply, we found that such a degradation is originated from the instability of density of states at the Fermi energy, while this instability is the result of strong repulsive interactions of certain Si-Fe-Si configurations in the Fe-Si alloy. Further calculations with Ni-doping are conducted as considering an attractive feature of Ni in Fe-bcc, whichconsequentlyachievedarecoveryofallelasticproperties.Thisisan encouraging experience of tailing electronic structures by introducing specific atomic configurations which adjusts bonding feature and the distribution of electrons toward enhancing specific physical properties.

Inthisstudy,thetightbindingcalculationsandthenon-equilibriumGreen's function formalism is employed to study the effect of the SF-barrier magnetization on the bias behavior of both components of STT in noncollinear FM/I/SF/I/FM junctions.

Although the diffusionenergybarriersofLiionsmayincrease(decrease)slightlyintheboron (phosphorus)-doped Si matrices, these changes were found to be highly-localized within the range of the nearest-neighbor distances. Furthermore, our calculated mechanical response of the Li-inserted Si matrices showed that the phosphorus-doped Si matrices can become more ductileandmoreeasilyundergoplasticdeformationuponhydrostaticstress,butonthe contrary, the Si matrices may become more brittle and stiffer in nature as it was doped with boron atoms. These results indicated that mechanical softening of the Si bond network can be the major reason that leads to the enhanced lithiation kinetics of c-Si by phosphorus-doping.

It is known that the dye loading of dyes on TiO2 will affect the light-harvesting efficiency. Recent work (J ACS, 2015) using X-ray reflectivity shows somedyeswithcyanoacrylicacidanchoringgrouparenotalignedwiththeir molecular long axes perpendicular to the substrate plane (tilt angle =0) on the TiO2 substrates, instead exhibit significant tilt angles from the surface normal of ~70. This result indicates the dyes with cyanoacrylic acid anchoringgroup may adsorbed on TiO2substrateswithdifferentbindingmodesratherthanthecommonlyaccepted bidentated modes using carboxylic group. Inthisstudy,weemployeddensityfunctionaltheory(DFT)andtime-dependent DFT (TD-DFT) to invesigate the effects of possible adsorption modes of dyes with cyanoacrylic acid anchoring group on TiO2 on dye loading. In particular, wefocusontheTPA-T-TTAR-AandTPA-TTAR-T-A1withsimilarmolecular structure, but with different tilt angles as well as dye loading on TiO2. Taking the conformationsofTPA-T-TTAR-AandTPA-TTAR-T-Aandtheiradsorptionmodes into consideration, our calculations are able to distinct their experimentally observed tilt angles Furthermore, we investigate the the effects of possible adsorption modes on the absorption spectra and electron injection properties.

Bulk WO3 exhibits different polymorphic phases, namely the monoclinic, triclinic, c-monoclinic,orthorhombic,tetragonal,andhexagonalphases,withincreasing temperature.Itiscommonlyacceptedthatatroomtemperature,WO3adoptsa monocliniclattice.Butrecently,manyexperimentalresultsdemonstratethe manifestationofvariousinterestingtemperature-controllednanomorphologiesof WO3, which is believed to have originated from the different polymorphs of WO3 [4-6]. In this work, using density-functional theory calculations, we investigate and study the various opto-electronic properties which will most likely be strongly affected by the poylmorphic state that WO3 adopts. We pay particular attention to the explicit approximations (ranging from the (semi)local to the range-separated hybrids) to the exchange-correlation functional to afford a more accurate description of these opto-electronic properties of WO3.

Spectroscopic techniques like Infrared Multiple-Photon Dissociation (IRMPD)andInfraredPredisociation(IRPD)areusedtoprobetheirvibrational signatures [1].In this study, we have chosen proton bound dimers of MeOH and Me2O as model systems in understanding the vibrational signature of anIHB.By adopting a reduced dimensional approach, key normal mode vibrations were chosen. The potential was constucted by scanning normal mode displacement vectors using MP2/aug-cc-pVDZ. It was found out that IHB stretch strongly couples with flanking group motions. The task of assigning the spectral lines was found to be nontrivial due totheentanglementofthenormalmodes.Lastly,acomparisonbetweenthe experimental spectrum independently measured by both Fridgens and J ohnsonsis discussed [2]-[3].

Liang-Chun Lin1,2 Kaito Takahashi2 1 Institute of Atomic and Molecular Sciences, Academia Sinica, Taipei, Taiwan 2Department of Chemistry, National Taiwan University, Taipei, Taiwan AtmosphericallyrelevantR1R2COO,so-calledCriegeeintermediates(CIs),includes simplest (R1=R2=H), mono-, ethyl-, and dimethyl- substituted CIs. These strong oxidizing species are the key intermediate in the ozonolysis of different kinds of alkenes. Alkenes arereleased to the troposphere in very large amounts from biogenic and anthropogenic sources. [1]CIsreactionswithatmosphericabundantwatervapoursisconsideredtobeavery important issue in atmospheric chemistry research. To uderstand these processes, we consider CIs +H2O and CIs +(H2O)2reactions, ignoring CIsreactions with bigger H2O clusters.Based on our calculation result, for atmospheric implication, CIs +(H2O)2 dominate the reaction on CIs +water vapour over CIs +H2O in cold upper troposphere layer even though [(H2O)2] is much lower than [H2O]. From the different trend in reactivity, discussed below, CIs +H2O reactions originally regarded very slow in room or lower temperature, actually play significant roles at high temperatures.In our research, we separated the whole reaction pathways into 2 parts: VDW (Van Der Waals)complexesformationandreactionsofVDWcomplexestoproducts.Thethermal equilibrium constants and rate constants were calculated using the Thermo program in the Multiwell program suite.The relative energies, for the reactant, VDW complex, transition stateandtheproductwereobtainedbythecompletebasissetextrapolationusingthe QCISD(T)methodwiththeDunningbasisatthegeometriescalculatedbyB3LYP/6-311+G(2d,2p).The harmonic and anharmonic vibrational frequencies wer also obtained at B3lYP level.On the basis of our calculations at different temperatures273.15 K, PH2O=16 Torr, kH2O*[H2O] =31 sec-1and k(H2O)2*[(H2O)2] =23952 sec-1;298.15 K, PH2O=16 Torr, kH2O*[H2O] =43 sec-1and k(H2O)2*[(H2O)2] =4416 sec-1;373.15 K, PH2O=16 Torr, kH2O*[H2O] =102 sec-1 and k(H2O)2*[(H2O)2] =110 sec-1.ForCIs +H2O reactions, total rate constants go up when temperature goes up; whereas for CIs +(H2O)2 case, total rate constants go down when temperature goes up. This opposing trend in the total rate constants comes from the fact that VDW complexes formation parts dominate the whole reactions for CIs +H2O system, and reactions of VDW complexes to productsdominatethewholereactionsforCIs+(H2O)2.

The results show that the incremental of hydration level correspondingly increases the area per lipid due to the penetration of water molecules into the sugar headgroups. But the single chain glycosides, Mal-C12(12%wat) and Mal-C12(23%wat), show a different trend in the area per lipid values. The bimodal distribution of angle between the chains of lipid with the z-axis for Mal-C12(23%wat) shows that the chain tend to orient near to the headgroup region and its angular distribution of the sugar rings from the headgroup possiblyindicate that the non-reducing sugarring flip and protrude into the headgroup region. Looking the behaviour of chain and headgroup, we suggest the Mal-C12(23%wat) system may be begin to shift into a metastable phase where, thelipidsmaytrytoreorientthemselvesintodifferentassemblystructure. Additionally, our simulation show that the intermolecular hydrogen bonding (HB) for all the oxygen sites of both the sugar rings in maltose headgroup do not change much although the bilayers are under the effect of water concentration and temperature. But thewater-lipidHBisdependenttothehydrationconcentrationwhere,whenthe hydrationlevelincreases,thewater-lipidHBincreasestoo.Wefoundthenon-reducingsugarsfromallbilayersystemsrotatesfasterthanthereducingsugar, because the reducing sugar placed in between the alkyl chain and the non-reducing sugarwhichhasbeenhydratedwithwater.Nonetheless,thepresenceof intermolecular HB helps to increase the sugar rings' rotational diffusion. Finally we found the exocyclic groups from all glycosides rotate much quicker than the sugar ring itself and there is no chirality effect to the rotational diffusion. Meanwhile, the orderparameterisquitesensitivetothetemperatureandwaterconcentrationand there is a subtle effect of chirality on the bond order parameter of lipids, especially in the racemic mixture of bilayer.

However, the accuracy of empirical MD depends greatly upon its force field, and the making thereof has traditionally been more of an arcane art rather than a modern science. As a response to this, a recent methodology of force field generation has started to gain grounds, known as Force Matching. The method uses forces calculated from ab initio methods to fabricate a force field, thereby reproducing the high level theory results of quantum mechanics. Further developments in this methodology has greatly increased itsrobustnessandcostefficiency.OnenotableimprovementisAdaptiveForce Matching (AFM)[1], which cut cost in referential ab initio calculations by reducing its size and theory level, but introduces sampling, weighing and iterative processes to make up for the loss of efficacy. Ultimately AFM drastically reduces cost by moving towards linear scaling. Despite that, recent AFM experiments have been limited to parametricallylinearforcefields,whichhaveheavilyrestrictedapplications. Therefore, the present work attempts to extend the subject to non-linear potentials by re-parameterizing a simple point charge water model, which is nonlinear, via an in house-developed AFM algorithm.

Bindingaffinityisenhancedwhenasparticacidisreplacedbyglutamicacidat residue 34 on ankyrin and resulted binding energy improved from -24.11 kcal/mol to -42.38 kcal/mol during 6-10 ns. A tighter binding mode between the designed ankyrin anddomainIII(wild-type)hasbeenobservedfromrootmeansquarefluctuation (RMSF) analysis. Besides, designed ankyrin is capable to bind better with
