PEDOT:PSS buffer layers have been processed with the standard annealing step used for organic solar cells device applications. The d.c. conductivity σ as a function of temperature for two heating rates under He and atmospheric air was studied. Moreover, the stability of the conductivity was investigated at different t…
First-principle investigations of the elastic, electronic and thermodynamic properties of TiC in NaCl structure under high pressure are conducted by using the plane-wave pseudopotential method and quasi-harmonic Debye model. The obtained lattice parameters, elastic constants and moduli at p=0 GPa and T=0 K are in very…
The Bi and the Te nano-powders are prepared by inert gas protected evaporation-condensation method; the n-type Bi2Te3 bulk materials with nano-layer and twin crystallite sub-structures are then synthesized by mechanical alloying and spark plasma sintering technique. The effects of grain size and microstructure on ther…
In order to find how the external electric field affects the SiN molecule completely, in the present work the density functional B3P86/6-31(g) method is adopted to optimize the ground state structure and the time dependent density functional theory TDDFT/6-31(g) is used to study the absorption spectra, emission spectr…
Three kinds of absorbers, based on square metal patch structure(SMP) metamaterials, resistance frequency selective surface (RFSS), and the combined SMP with RFSS structures, are designed, respectively. The absorptivities of these absorbers are simulated and analyzed by FDTD method. The simulation results indicate that…
Radiation processing involves the use of natural or manmade sources of high energy radiation on an industrial scale. The principle of radiation processing is the ability of high energy radiation to produce reactive cations, anions and free radicals in materials. The industrial applications of the radiation processing…
The present study examines the behavior of steel pipeline elbows subjected to strong cyclic loading conditions. A set of experiments is conducted where in-plane cyclic bending with constant amplitude is applied on the elbow specimens by controlling the elbow enddisplacements, resulting in failure within the low-cycle-…
A simple approach has been adopted to prepare ZnO nanorods with N-cetyl-N,N,N-trimethyl ammonium bromide (CTAB) assisted hydrothermal route at 200 °C. The presence of CTAB favours the orientation growth of ZnO nanorods. The effect of reaction conditions on the morphology, crystallization and optical properties of the…
Charge density studies of chemical bonds for two iron complexes, [(NO)Fe(S,S-C6H4)2] [PPN] (1), where PPN = N(Pph3)2 and Fe3(NO)3(S,S-C6H4)3 (2) are investigated in terms of the topological properties at bond critical points based on the ‘atoms in molecule’ theory. The one electron reduction form (1R) of complex 1 and…
We study an array of graphene nano sheets that form a two-dimensional S = 1/2 Kagome spin lattice used for quantum computation. The edge states of the graphene nano sheets are used to form quantum dots to confine electrons and perform the computation. We propose two schemes of bang-bang control to combat decoherence a…
The biological synthesis of nanoparticles materializes as an eco-friendly and stimulating approach in the field of nanotechnology. In the present investigation, we report the extracellular biosynthesis of silver nanoparticles (AgNP`s) using entire plant extracts (Mollugo nudicaulis) for the reduction of aqueous Ag+ io…
The epoxidation of soybean oil is industrially carried out by using peroxyacid generated in situ by reacting concentrated hydrogen peroxide with acetic or formic acid, in the presence of a mineral acid as a catalyst. The reaction is generally highly exothermic and an excessive increase of temperature is proved to occu…
Abstract The key point of waste activated sludge (WAS) pretreatment is to rupture the cell wall for allowing the release of intracellular matter that acts as a bioavailable substrate in anaerobic digestion processes. In this regard, ultrasonic irradiation has been one of the most effective tools owing to the unique pr…
Mass production of carbon nanotubes (CNTs) on an easy soluble support has been achieved by chemical vapor deposition method. CNTs have been synthesized using nickel formate as catalyst precursor at 700˚C. The structure of the grown product was characterized by scanning electron microscopy, transmission electron micros…
2価金属イオンのCa21とMg21が共存する水溶液から，共沈法によってCa–Mg–Al系層状複水酸化物（Layered Double Hydroxide，以下LDH）の合成を行った．得られた生成物を用いて水溶液中で陰イオン種を形成するAs(III), B, Cr(VI)およびSe(IV)の除去を行った．生成物の物性や陰イオン種の除去特性におよぼすCa21とMg21の混合比の影響について検討した．pH 10の共沈操作では水酸化アルミニウム（AH）とハイドロタルサイト様化合物（HT）が生成した．このとき，Mg21とAl31は全量沈殿するのに対し，Ca21の沈殿率は極めて低い．Ca21–Mg21混合系から得られたAHとHTの複合体は，A…
Ever since the discovery of carbon nanotubes, there has been an increasing interest in technologies that rely upon these incredibly small particles for their unique properties. However, assessment of their biological consequences has been riddled with assay limitations. Here, we describe application of a 3-(4,5-dimeth…
