Thin films of CdTe were deposited on glass substrates by thermal evaporation. From the XRD measurements itis found that the films are of zinc-blende-type structure. Transmittance, absorption, extinction, and refractive coefficients are measured. Electronic structure, band parameters and optical spectra of CdTe were ca…
To clarify the yielding mechanism of small hydrocarbon molecules in chemical sputtering between hydrogen and graphene sheets, we made classical molecular dynamics simulation with modified Brenner's REBO potential which we proposed to deal with chemical reaction. As the simulation model, we prepared more realistic phys…

In recent simulations of semiflexible equilibrium polymers [X. Lu and J. T. Kindt, J. Chem. Phys. 120, 10328 (2004)] a roughly biexponential distribution of chain lengths was observed in the nematic phase. In this study, we show that a theory representing the nematic phase as an equilibrium mixture of randomly oriente…
The effects of non-ideal experimental configuration on the mechanical resonance of boron (B) nanowires (NWs) were studied to obtain the corrected value for the Young’s modulus. The following effects have been theoretically considered: (i) the presence of intrinsic curvature, (ii) non-ideal clamps, (iii) spurious masse…

Abstract A novel class of wholly aromatic poly(ester‐imide)s, having a biphenylene pendant group, with inherent viscosities of 0.32–0.49 dL g −1 was prepared by the diphenylchlorophosphate‐activated direct polyesterification of the preformed imide‐ring‐containing diacid, 4‐ p ‐biphenyl‐2,6‐bis(4‐trimellitimidophenyl)p…

Give and take: A molecular cluster that readily takes up and stores two molecules of H2 also rapidly releases (milliseconds) the stored H2 by a simple redox process. This process represents a new method of hydrogen storage and release from a well-defined molecular material.
Two different methods were applied to fabricate cuprous-oxide (Cu 2 O) nanoparticles (NPs) in silica glasses (SiO 2 ), namely (i) low oxygen-pressure (LOP) oxidation of Cu NPs, which had previously been formed in SiO 2 by implantation of Cu ions and (ii) two-step annealing of Cu NPs in atmospheric-pressure oxygen gas…
Melts of poly(ethylene terephthalate) were solidified by rapid compression to 2 GPa within 20 ms and by a series of comparative processes including natural cooling, slow compressing and rapid cooling, respectively. By combining XRD and differential scanning calorimetry data of the recovered samples, it is made clear t…
Recently, ultra-small diameter single wall nanotubes with diameter of ∼0.4 nm have been produced and many unusual properties were observed, such as superconductivity, leading to a transition temperature T c ∼15 K, much larger than that observed in the bundles of larger diameter tubes. By a comparison between two diffe…
The low temperature EPR spectra of the unique nanometer-scale molecular magnet V(15) are analyzed within the three-spin model preserving trigonal symmetry. The Hamiltonian includes isotropic and antisymmetric (AS) exchange interactions introduced by Dzyaloshinsky (Zh. Eksp. Teor. Fiz. 32, 1547 (1957) [Sov. Phys. JETP…
Pharmacokinetics of the doxorubicin (DOX) conjugates with magnetite nanoparticles of the core/ shell type in mice following i.v. injection in a dose of 12.5 microg Fe/g tissue w/w was studied using electron spin resonance technique (ESR). Conjugation of the DOX with magnetic nanoparticles was shown to considerably dec…
The neutralization of low energy 7Li+ scattered from Au nanoclusters deposited on TiO2(110) was measured with time-of-flight spectroscopy as a function of cluster size, emission angle, and ion energy. The neutralization shows maxima for cluster diameters approximately 3 nm, and again for thick Au films. The data are c…

The coordination chemistry of the tetrakis(thiophosphinato)resorcinarene sulfur-donor ligands [(C6H2CH{CH2CH2Ph})4{OC(O)R}4{OP(=S)Ph2}4] (L), where R = OCH2Ph, 4-C6H4CH3, C6H11, C4H3S, or OCH2CCH, is reported. Both silver(I) and gold(I) form cationic complexes of the type [LM2]2+, in which the ligand acts as a bis(che…
The (1 − x ) La 0.7 Sr 0.3 MnO 3 + x TiO 2 ( x ∼ 0, 0.05, 0.10, 0.15 and 0.20) composites were prepared via a solid-state reaction process. The microstructural, magnetic and transport properties of the composites were investigated. X-ray diffraction reveals that both the compounds maintain their identities, that is, t…
This paper is the fourth in a series exploring the physical consequences of the solidity of highly viscous liquids. It is argued that the two basic characteristics of a flow event (a jump between two energy minima in configuration space) are the local density change and the sum of all particle displacements. Based on…
Hollow spherical particles of calcite with a diameter of 2−10 μm were synthesized on a polyvinyliden difluoride (PVDF) membrane blotted with crude organic matrices prepared from the pearl oyster shell in a supersaturated solution of calcium carbonate. Examination of the produced particles as a function of the reaction…
