Far-infrared spectroscopy and X-ray diffraction Rietveld structure-refinement of synthetic kinoshitalite (Kn) solid solutions, BaMg 3 [(Al 2-x Ga x )(Si 2-y Ge y )]O 10 (OH,OD,F) 2 : (x = 0.0-2.0, y = 0.0-2.0), show that there is complete solid solution for all compositions in each (OH/OD)- and F-series: [4] [Al 2 (Si…
To improve the practical capacity of TiO2(B), optimization of precursor (K2Ti4O9 and Cs2Ti5O11), solvent (EC+DEC, EC+DMC and EC+DMC) in electrolyte and homogeneity (mixing with a mortar or wet-ball milling machine) of Ketjen Black (KB) as conductive agent was conducted. Use of Cs2Ti5O11 precursor reduced the content o…
Dimethyl sulfoxide (DMSO) electrolytes were investigated for the electrodeposition of bismuth telluride films for thermoelectric applications. The investigation revealed the influences of electrolyte ion concentration, deposition potential, and temperature on the alloy composition. Full composition range of bismuth te…
Optical, electrochemical and photovoltaic properties of novel donor-acceptor copolymers containing dithienylthienothiadiazole derivatives and 9,9-bis(2-ethylhexyl)fluorene or 2,5-diisopentoxybenzene units were studied. The copolymers exhibited long-wavelength absorption, and possess small optical bandgap in the range…
Alternative supports for polymer electrolyte membrane fuel cells were synthesized and catalytic activity was explored using electrochemical analysis. High surface area, molybdenum nitride supports were synthesized by rapidly heating a gel of polyethyleneimine bound molybdenum in a tube furnace under a forming gas atmo…
A bit patterning process using the ferromagnetic (FM)-antiferromagnetic (AF) transition in [001]-oriented L10 FePt1-xRhx films was investigated. First, the composition (x) dependence of magnetization (Ms) and magnetocrystalline anisotropy (Ku) of the films was studied. The films with 0 ≤ x ≤ 0.32 showed ferromagnetism…
The geometrical and electronic structures of a chemically disordered face-centered-cubic- (fcc) FePt cluster capped with various organic ligands, including propanoic acid, propylamine, and propanethiol, were investigated by means of density functional theory (DFT) calculations within a generalized gradient approximati…
We report results for the dependence of the mechanical properties of ordered mesoporous silica structures on the pore diameter based on molecular-dynamics simulations. We examine structures with spherical pores arranged in a simple cubic lattice and cylindrical pores arranged in a square lattice subjected to uniaxial…
Density functional theory with local spin density approximation is applied to study the evolution of ferromagnetism in SrxPb1−xRuO3 (0≤x≤1). Besides the enhanced Pb–O covalence and Pb–Ru hybridization, the Jahn–Teller effect, which favors the low-spin state (S=0) of Ru4+ in a stretched oxygen octahedra, is found to be…
Layer-structured MnO2 electrodes were synthesized by using a nanosheet process and its electrode properties for electrochemical capacitors were investigated in aqueous solutions. Prepared MnO2 nanosheet had a plate like morphology, 3 µm in width and 3 nm in thickness. In an aqueous 0.1 M Na2SO4 solution, the nanosheet…
The development of Light Emitting Diode (LED) technology over the past thirty years, has led to an exponential increase in device efficiency and light output, such that LEDs are now becoming the light source of choice for virtually all applications. High brightness LEDs (HB LEDs) are driving market growth of around 20…
Zinc oxide (ZnO) thin films were grown on glass and copper substrates by the Successive Ionic Layer Adsorption and Reaction (SILAR) technique. ZnO films are obtained by successive immersion of a substrate in an aqueous solution containing: ZnSO4 with different molarities, 6ml/100ml 13.15 M aqueous ammonia solution and…
Both n-type and p-type semiconductor CdTe were synthesized by electrodeposition from an aqueous deposition bath. Electrodeposition potential was found to be the key factor to synthesize the CdTe semiconductor of any specific conductivity type. The electrodeposition potentials of -0.4 V and 0.4 V versus Ag/AgCl generat…
A detailed study of the effects of binary spreading sequences (BSS) excitation in the magnetization dynamics of exchange-biased spin-valves driven by spin-transfer-torque has been carried out by full micromagnetic modeling. We show that the use of BSS allows to trigger the magnetization reversal by exciting its main p…
Ordered arrays of vertically oriented Ti-Mn oxide nanotubes were synthesized by a simple anodization method. XRD pattern showed presence of TiO2 in the form of anatase and rutile in addition to Mn2O3 after annealing at 500 ºC. An experimental battery with Ti-Mn oxide nanotubes as anode and LiCoO2 cathode was assembled…
Abstract Emulsion copolymerization of ω‐chlorotetrafluoroethyltrifluorovinyl ether (Cl(CF2)2OCF = CF2 (FVE)) with tetrafluoroethylene (CF2 = CF2 (TFE)) was investigated at various monomer ratios. The copolymerization rate is below the rate of TFE homopolymerization and the copolymerization kinetics depends on the FVE…
The stability of negative charge in nitrogen-rich silicon nitride films deposited by plasma-enhanced chemical vapor deposition is investigated by analyzing the influence of storage temperature, postdeposition thermal annealing, and the presence of a tunnel oxide. The results are compared to a charge decay model. Compa…
For the next generation lithography (NGL), several technologies have been proposed to achieve the 22nm-node devices and beyond. Extreme ultraviolet (EUV) lithography is one of the candidates for the next generation lithography. For lithography processes, the Line width roughness (LWR) and the pattern collapse of resis…
