Prediction of a New Phase of CuxS near Stoichiometric Composition

Prashant Khatri、Muhammad N. Huda2015-01-01International Journal of Photoenergy

Cu2S is known to be a promising solar absorber material due to its suitable band gap and the abundance of its constituent elements. Cu2S is known to have complex phase structures depending on the concentration of Cu vacancies. Its instability of phases is due to favorable formation of Cu vacancies and the mobility of…

Precise control of nanoparticle surface by host–guest chemistry for delivery to tumor

Hisato Matsui、Motoki Ueda、Isao Hara 等 4 位作者2015-01-01RSC Advances

A nanocarrier with a diameter less than 30 nm was prepared here by using host–guest chemistry. A defined number of functionalized guests was incorporated in the nanocarrier, which was a nice tumor imaging probe without showing the ABC phenomenon.

Superconducting transition properties of grain boundaries in MgB2 films

Sung Hoon Lee、Soon-Gul Lee、Soon-Gul Lee 等 5 位作者2015-01-01Journal of the Korean Physical Society

The intergrain interface of unconventional superconductors suppresses the order parameter and, thus, serves as a bottleneck for the supercurrent. Such a characteristic of the grain interface is a major limiting factor for the lossless-current-carrying capacity of superconducting transmission lines on the one hand, but…

Interdendritic spacing in growth processes with a mushy layer

Dmitri V. Alexandrov、A. V. Britousova2015-01-01AIP conference proceedings

Exact analytical solutions of nonlinear equations describing directional solidification of binary melts with a mushy layer are constructed. The primary interdendritic spacing in a mushy layer is analytically found on the basis of the selection theory of stable dendritic growth.

Formation, reactivity and redox properties of carbon- and sulfur-bridged diiron complexes derived from dibenzothienyl Schiff bases: effect of N,N- and N,P-chelating moieties

Kiyokazu Santo、Masakazu Hirotsu、Isamu Kinoshita2015-01-01Dalton Transactions

Dibenzothienyl Schiff bases, DBT-NN and DBT-NP, were derived from condensation of 4-formyldibenzothiophene with N,N-dimethylethylenediamine and 2-(diphenylphosphino)ethylamine, respectively. A photochemical reaction of [Fe(CO)5] with DBT-NN produced diiron complexes, [Fe2(μ-DBT-NN)(CO)6] (1) and [{Fe(μ-BPT-NN-κ(3)S,C,…

Influence of NH4Cl on Hydrothermal Formation of α‐CaSO4·0.5H2O Whiskers

Haoyuan Chen、Jing Wang、Sichao Hou 等 4 位作者2015-01-01Journal of Nanomaterials

The influence of NH4Cl on hydrothermal formation of CaSO4·0.5H2O whiskers from CaSO4·2H2O precursor at 135°C was investigated in this paper. Compared with the blank experiment, the presence of 3 × 10−2 mol·L−1 NH4Cl led to the increase of the lengths of the whiskers from 50 to 160 μm to 150 to 300 μm and the decrease…

Hanjung Kwon、Sun–A Jung、Wonbaek Kim2015-01-01MATERIALS TRANSACTIONS

(Ti,Cr)C was synthesized and consolidated in situ by spark plasma sintering (SPS) of two TiC/Cr3C2 powder mixtures of distinctly different particle sizes. SPS of both mixtures successfully produced single-phase (Ti,Cr)C in two minutes at 1800°C. It was found that the nano-scale mixture consists of fine and uniformly d…

Qinmei Wang、Ying Chen、Lichun Wang 等 6 位作者2015-01-01International Journal of Nanomedicine

Successful in vivo gene delivery mediated by nonviral vectors requires efficient extracellular and intracellular gene delivery, but few studies have given attention to the former. That is why numerous gene delivery systems have succeeded in vitro, while the expected clinical success has not come about. To realize effi…
