Glass transition temperature(Tg) of 20BaO·10Fe2O3·xWO3·(70−x)V2O5 glasses showed a step-by-step increase from 339 to 470°C when x was increased from 0 to 50, together with a concordant increase in crystallization temperature(Tc) from 406 to 531°C. Plot of Tg against quadrupole splitting(Δ) of FeIII in the Mössba…
A major clinical problem of high relevance in the cardiovascular field is late stent thrombosis after implantation of drug eluting stents (DES). Clinical widely used DES currently utilize durable polymer coatings, which can induce persistent arterial wall inflammation and delayed vascular healing resulting in an impai…
This paper describes the investigation of manganese modified CdTe/CdS quantum dots as a fluorescence probe for trace copper detection. Manganese modified CdTe/CdS quantum dots were prepared in aqueous solution and were characterized by ultraviolet-visible absorbance, fluorescence spectra, transmission electron microsc…
In this study, the oxidation of ammonia (NH3) to form nitrogen was investigated by selective catalytic oxidation (SCO) over a Pt-Rh binary catalyst fabricated by the incipient wetness impregnation process in a tubular fixed-bed flow quartz reactor (TFBR). The catalysts were analysed by three-dimensional excitation-emi…
Janus particles have attracted significant attention in recent years, due to their potential in nanomanufacturing. Their asymmetric features impart unique physical and chemical properties, which can be tuned and utilized to control their solution-state assembly. While several examples of Janus nanostructures have been…
Highly oriented and nanostructured hybrid thin films made of regioregular poly(3-hexylthiophene) and colloidal CdSe nanocrystals are prepared by a zone melting method using epitaxial growth on 1,3,5-trichlorobenzene oriented crystals. The structure of the films has been analyzed by X-ray diffraction using synchrotron…
Compared to the p-n junction type device (Device A) with an n-type ZnO nanowire (n-ZnO)/p-type silicon (p-Si) hybrid structure, the newly designed device (Device B) with an n-ZnO/reduced graphene oxide sheet (rGO)/p-Si hybrid structure displays interesting electrical characteristics such as lower turn-on voltage and b…
A combination of in situ time-resolved DXAFS and ICP-MS techniques reveals that the formation process of Rh nanoparticles (NPs) from rhodium trichloride trihydrate (RhCl(3)·3H(2)O) in ethylene glycol with polyvinylpyrrolidone (PVP) at elevated temperature is a first-order reaction, which indicates that uniform size Rh…
A PbTe thin film with near-infrared photoconductive characteristics is assembled from monodisperse PbTe nanocrystals (NCs). Monodisperse PbTe NCs show large absorption tunability (>400 nm) by a rapid injection solution-phase synthesis route. In order to obtain smooth close-packed NC thin films on a Si/SiO2 substrate w…
The functionalization of metal nanoparticles provides access to materials with unique chemical and physical properties for a wide range of applications, e.g. in catalysis, optoelectronics and material science. However, the fundamental light induced charge transfer processes and electronic interactions at the functiona…
Self-construction of films using polyelectrolytes bearing complementary chemical groups is a recent emerging concept in the coating field. Herein, we describe the one-pot morphogen film self-construction through formation of covalent bonds between polyelectrolytes and homobifunctional spacers by Huisgen click-chemistr…
Passive films formed on Type 304 and 316 stainless steels under a wet-dry cyclic condition were characterized using X-ray photoelectron spectroscopy (XPS). Cr enrichment in the passive films during early stage of the wet-dry cycles occurred due to the preferential oxidation of Cr and the selective dissolution of Fe. H…
Hexagonally arrayed structures of colloidal crystals with uniform particle size are good candidates for templates for synthesizing porous nanostructures. Herein, we present the first reported use of three-dimensionally (3D) ordered porous structures to increase the energy storage abilities of conducting polymer based…
A π-radical ligand (9-[4-(6-oxo-1,5-dimethylverdazyl)phenyl]-10-[5-(2,2'-bipyridyl)ethynyl]anthracene, L1) with a photo-excited high-spin quartet state (S = 3/2) and its iron(II) complex [Fe(L1){H(2)B(Pz)(2)}(2)] (1) {H(2)B(Pz)(2)(-) = dihydrobis(1-pyrazolyl)borate} were synthesized as a candidate for a new strategy f…
A crystalline Ti2Ni alloy was mechanically milled and subsequently annealed to form a non-equilibrium Ti2Ni alloy. This non-equilibrium structure could restrain the formation of irreversible metal hydride during charging. Consequently, we demonstrated that the alloy had a discharge capacity of 336 mAh g−1, which was m…

Owing to the complexity of cancer biology, successful treatments must make use of multidisciplinary approaches that include genetic biology, materials science, chemistry, and physics. The development of nanotechnology as a mature science has provided new tools for the early detection and treatment of cancer by combini…
We offer our viewpoint on the nature of amorphous ices produced by pressurization of crystalline ice Ih and the inter-relationship between them from an atomistic perspective. We argue that the transformation of high density amorphous (HDA) ice from crystalline ice is due to a mechanical process arising from the instab…
