Time evolution photoluminescence (PL) studies of ferroelectric liquid crystal (FLC) mixtures doped with different concentrations of ZnS and CdS quantum dots (QDs) are carried out. Remarkable enhancement in the PL intensity and a significant shift in the emission band of FLC materials are observed by doping with a suit…
OBJECTIVE: The purpose of this work was to prepare a stable paclitaxel nanosuspension and test it for potential use as a targeted chemotherapeutic. Different particle coatings were employed to assess their impact on cellular uptake in vitro. In vivo work was then performed to demonstrate efficacy in tumor-bearing mous…
Boron and nitrogen substitutional impurities in graphene are analyzed using a self-consistent tight-binding approach. An analytical result for the impurity Green's function is derived taking broken electron-hole symmetry into account and validated by comparison to numerical diagonalization. The impurity potential depe…
We have investigated the failure modes of single crystal aluminium under decaying shock loading by using molecular dynamics simulations. The microstructure evolution during the failure is presented in terms of the central symmetry parameter, and the corresponding pressure and temperature profiles are calculated and di…
ABSTRACT A novel polyarylene ether nitrile terminated with phthalonitrile (PEN‐ t ‐Ph) was synthesized by a simple solution polycondensation of biphenyl and hydroquinone with 2,6‐dichlorobenzonitrile, followed by termination with 4‐nitrophthalonitrile. The PEN‐ t ‐Ph/1,3,5‐Tri‐(3,4‐dicyanophenoxy) benzene (TPh) system…
This study analyses the flexural and impact strength of polypropylene reinforced with stone ground wood pulp (SGWP) and the effect of a maleated‐polypropylene (MAPP) coupling agent on the mechanical properties of these composites. Composites prepared in the absence of the coupling agent showed a very light positive li…
Using scanning tunneling microscopy and spectroscopy, we have analyzed the growth of ZnO thin films on a Au(111) support. Because of the 12% lattice mismatch with the metal beneath, ZnO develops a (0001)-oriented coincidence lattice that gives rise to a well-ordered hexagonal Moiré pattern with 2.2 nm periodicity. Thi…
One-dimensional (1-D) chain complexes constructed by metal-metal bonds containing three types of metal species-platinum, rhodium, and copper-have been rationally synthesized and characterized by single-crystal X-ray analyses and physical measurements. The paddlewheel or lantern type complex, [Rh2(O2CCH3)4] (i.e., [Rh2…
Enhanced high-field transport critical current densities observed for ex situ PIT processed Ag/(Ba, K)Fe2As2 thin tapes, Togano, Kazumasa, Gao, Zhaoshun, Taira, Hideaki, Ishida, Shigeyuki, Kihou, Kunihiro, Iyo, Akira, Eisaki, Hiroshi, Matsumoto, Akiyoshi, Kumakura, Hiroaki
Linear, ring and 3D structures of (ZnTe)n clusters for n = 2–6 are completely optimized using B3LYP/LanL2DZ basis set. The stability, dipole moment and point group for linear, ring and 3D structures are studied. The stability of the clusters is found to increase with the increase in the cluster size. The dipole moment…
ABSTRACT Ammonia borane (AB; NH 3 BH 3 ) is one of the most promising materials for hydrogen storage applications, mainly due to its high gravimetric hydrogen storage capacity of 19.6 wt%. In this paper, we present an exclusive kinetic analysis of AB thermolysis. Three methods are used for kinetic analysis of the ther…
The rapidly expanding field of surface-enhanced Raman spectroscopy (SERS) has helped fuel an intense interest in noble metal nanoparticle synthesis. An in-suspension approach for quantifying SERS enhancement and relating that enhancement to a spontaneous Raman equivalent signal is described. Gold nanoparticles of vari…
A new type of diglycidyl ether of bisphenol A (DGEBA) epoxy‐based hybrids has been developed by the incorporation of varying percentages of glycidyl‐terminated hyperbranched polysiloxane (HPSiE) into DGEBA resin and are characterized for their physicochemical, thermal, mechanical, and dielectric behaviors by modern an…
In situ growth of bismuth (Bi) nanoparticles on bulk SrBi 2 Ta 2 O 9 (SBT) platelet is achieved by UV light illumination of SBT in aqueous glucose solutions. Interestingly, the as-produced Bi nanoparticles (NPs) are uniformly oriented with the epitaxial relationship of [001] Bi //[110] SBT, appearing as meso-single-cr…
Ytterbium‐doped Sr 5 ( PO 4 ) 3 F transparent ceramics have been developed through spark plasma sintering ( SPS ) with a low sintering temperature and short dwelling time. The XRD patterns show a polycrystalline hexagonal phase, and the TEM microstructure characterization indicates that the ceramics have a narrow grai…
The ternary composites of 1,4‐cis polybutadiene rubbers (BR), styrene–butadiene rubber (SBR), and natural rubber (NR) foams containing chemical blowing agents Oxybis (benzene sulfonyl) hydrazide (OBSH) were prepared by two‐stage compression molding technique with various precured degrees. Foam force rheometer indicate…
We investigate the phase behaviour of 2D mixtures of bi-functional and three-functional patchy particles and 3D mixtures of bi-functional and tetra-functional patchy particles by means of Monte Carlo simulations and Wertheim theory. We start by computing the critical points of the pure systems and then we investigate…
To investigate the relationship between the production of poly(3-hydroxybutyrate) (PHB) and metabolic changes during different growth phases, a non-sterile batch fermentation process involving an alkalophilic and halophilic bacterium, Halomonas sp. KM-1, was used. Intracellular metabolites were analyzed using gas chro…
The perovskite form of the Mn2FeSbO6 oxide has been obtained at 5.5 GPa and 1523 K.

Coatings consisting of polymer brushes are an effective way to modify solid interfaces. Polymer brush-modified hybrid particles have been prepared by surface-initiated activators regenerated by electron transfer atom transfer radical polymerization (SI-ARGET ATRP) of 2-(diethylamino)ethyl methacrylate (DEA) on silica…
