Indium oxide (In2O3) nanorods were grown on silica substrates by using the self-catalytic vapor–liquid–solid growth process. The photoresponse of the nanorods was compared to that of the thin film, tin-doped indium oxide (ITO). The nanorods demonstrated a wavelength-dependent photoresponse with high responsivity of 1.…

Blends of poly[( R )-3-hydroxybutyrate] (PHB) with poly( l -lactide acid) (PLLA) were prepared to study the crystallization behavior of PHB in the blends. To investigate the effect of molar mass of PLLA on the crystallization of PHB, two types of PLLA with high and low molecular weight, HPLLA and LPLLA, were used. It…

The World, and much of Nature that we see within it, experiences an environment of reduced symmetries. For example, living organisms are dependent on asymmetric or dissymmetric structures for their life processes. In the solid state, a large number of space groups are chiral. Conversely, in liquids, the effects of red…

We have prepared and characterized a series of multifluorocarbon end-functional polyethylene additives, which when blended with polyethylene matrices increase surface hydrophobicity and lipophobicity. Water contact angles of >112° were observed on spin-cast blended film surfaces containing less than 1% fluorocarbon in…

Using Monte Carlo simulations of a coarse-grained model, we explore the equilibrium morphologies of symmetric diblock copolymers between two chemically patterned surfaces. The chemical patterns on the surfaces consist of periodic stripes of width W with a periodicity L s . The stripes on the two chemical patterns are…

Two novel mononuclear five-coordinate nickel complexes with distorted square-pyramidal geometries are presented. They result from association of a tridentate "half-unit" ligand and 6,6'-dimethyl-2,2'-bipyridine according to a stepwise process that highlights the advantage of coordination chemistry in isolating an unst…

The present work describes the formation of Pegylated polyurethane and Lysine-coated polyurea nanoparticles obtained from O/W nano-emulsions via an interfacial polycondensation process in the aqueous solution/polysorbate 80/diisocyanate/medium chain triglyceride systems. The initial nano-emulsions were prepared using…

We demonstrate that a simple gallium(III) complex, [Ga(phen)(2)Cl(2)]Cl (phen = 1,10-phenanthroline), can serve as a homogeneous catalyst for the epoxidation of alkenes. The olefin epoxidations proceed relatively quickly at mild temperatures and, under optimum conditions, are highly selective for the epoxide product.

For the development of vascular tissue engineering, the impact of endothelial cells (ECs) on smooth muscle cell (SMC) spreading, proliferation, and differentiation is explored in the current study using a coculture model. In this coculture model, SMCs were encapsulated in a biomimetic hydrogel based on methacrylated d…

The electronic properties of graphene supported by the (0001) SiO 2 surface are theoretically studied using density functional theory. It is found that the electronic attributes of graphene on (0001) SiO 2 strongly depend on the underlying SiO 2 surface properties and the percentage of hydrogen passivation. By applyin…

Lysine degradation through the saccharopine pathway has been shown only in plants and animals. Here, we show that bacteria possess the genes encoding lysine-ketoglutarate reductase (LKR) and saccharopine dehydrogenase (SDH). In Silicibacter, the contiguous lkr and sdh genes are interspersed, in another frame, by a pol…
