Six metal carbido-carbonyl clusters have been isolated and recognized as members of a multivalent family based on the dioctahedral Rh(10)(C)(2) frame, with variable numbers of CO ligands, AuPPh(3) moieties, and anionic charge: [Rh(10)(C)(2)(CO)(x)(AuPPh(3))(y)](n-) (x = 18, 20; y = 4, 5, 6; n = 0, 1, 2). Anions [Rh(10…
Natural rubber (NR) based nanocomposites containing a constant amount (50 phr) of standard furnace carbon black and carbon nanotube (CNT) at a concentration from 1 to 5 phr have been prepared. Their dielectric (dielectric permittivity and dielectric loss) and microwave properties (coefficients of absorption and reflec…
Pair-rule genes are crucial for generating dual segment periodicity for body plan patterning in Drosophila. Bombyx mori is an intermediate germband insect, in which the formation of posterior segments via sequential addition follows a different process from that in Drosophila, although it is somewhat comparable to the…
The temperature-dependent infrared spectroscopy studies of one novel antiferroelectric liquid crystal (AFLC), known under the MHPSBO10 acronym, have been undertaken. The FT-IR measurements have been performed for homeotropic and planar heterogeneous sample geometries. The main order parameters have been determined and…
The change in free energy (∂G) of a system at constant pressure, volume and temperature equals the change in internal energy (∂U) minus the product of the change in entropy (∂S) times temperature (T): ∂ ∂ ∂G U T S= − (8.1) The change in free energy of a occulated colloidal network as a function of changes in extensio…
In the title compound, [Cu(2)(C(13)H(11)N(4)S)(2)(N(3))(2)], the Cu(II) cation is N,N',S-chelated by the deprotonated Schiff base ligand and is coordinated by the azide anion, while an N atom from an adjacent azide anion bridges the Cu(II) cation at the apical position with a longer Cu-N distance of 2.533 (3) Å, compl…
The tearing and rheological properties of poly(lactic acid) (PLA)/poly(ethylene glutaric-co-terephthalate) copolyester (FP) blends were investigated using a wide range of blending ratios. The tearing strength values of PLA/FP were always significantly higher than that of the PLA specimen. The melt flow indexer and cap…
We demonstrate for the first time a large-scale ac plasma display panel enhanced by localized surface plasmon (LSP) resonance owing to Ag nanoparticles. In order to generate plasmon resonance fitted to the blue-emitting phosphor, we deposited Ag nanoparticles on the phosphor layer by a spray method using large-scale f…
In the title compound, [InCl(3)(C(12)H(12)N(2))(CH(3)OH)]·CH(3)OH, the In(III) atom is six-coordinated in a distorted octa-hedral geometry by two N atoms from a chelating 4,4'-dimethyl-2,2'-bipyridine ligand, one O atom from a methanol mol-ecule and three Cl atoms. In the crystal, inter-molecular O-H⋯O and O-H⋯Cl hydr…
Zn‐Al‐salicylic nanohybrid layers have been prepared and used as fillers for polyvinyl alcohol (PVA). Nanohybrid layers of a broad absorption area in UV region were completely and uniformly dispersed in a continuous polymer matrix. PVA and PVA nanohybrid composite (NHC) films were exposed to UV irradiation. Thermal pr…
Enigmatic millimetre-scale micro-concretions with pseudocrystal faces and dominated by green clay minerals occur in unfossiliferous siliciclastic mudstone of the Lower Ordovician (479.0–466.0 Ma) Tonggao Formation, South China. The fossil-free mudstone unit is associated with local biodiversity decline. The mineralogy…
Good relations: the electron lifetime (τ) has turned out to be one of the most influential parameters in the performance of quantum-dot- and dye-sensitized solar cells. Different approaches for the analysis of the open-circuit-potential decay are presented, showing the strong effect on the calculated lifetime values o…
Membrane proteins are intrinsically involved in both human and pathogen physiology, and are the target of 60% of all marketed drugs. During the past decade, advances in the studies of membrane proteins using X-ray crystallography, electron microscopy and NMR-based techniques led to the elucidation of over 250 unique m…
Perfluoroalkylated surfactants having a quaternary ammonium surrounded by three hydroxyl groups as hydrophilic moiety and a perfluoroalkyl chain as tail were obtained by coupling diethanolamine with perfluoroalkylated epoxide followed by quaternisation. The amphiphilic properties of these surfactants were investigated…
A series of organic–inorganic hybrid materials were prepared from a hyperbranched polyimide precursor (hyperbranched polyamic acid), tetramethoxysilane, and/or 3-glycidyloxypropyl-trimethoxysilane via a sol-gel process. The hyperbranched polyimide-silica hybrids, whose polyimide moieties were based on commercially ava…
“Water-in-water” emulsions of cross-linked and hydrophobically associating cationic polyacrylamide (CHCPAM) with cationic groups (methacrylatoethyl trimethyl ammonium chloride, DMC), hydrophobic groups (octadecyl methacrylate, OA), and cross-linked groups (N, N’-methylene bisacrylamide, MBA) were prepared by dispersio…

The full-potential linearized augmented plane wave method (FP-LAPW) within density functional theory, using the generalized gradient approximation, is used to study the structural and electronic properties of zinc-blende B y Al x Ga 1-x-y N quaternary alloys that match the lattice of an AlN substrate. The range of com…
Two Zn(II) and Hg(II) bromide salts, [EMI]2[ZnBr4] (1) and [EMI][HgBr3] (2), have been synthesized under ionothermal conditions using 1-ethyl-3-methyl imidazolium bromide ([EMI]Br) as solvents. 1 consists of tetrahedral anion [ZnBr4]2− and 2 consists of 1D double chain locating in the cavities surrounded by [EMI]+ cat…
The effects of friction on surface crack growth behavior from pre-indentations of HIP-Si 3 N 4 were investigated under rolling contact fatigue (RCF). Near surface contact stress distributions were calculated by Hanson's analytical method, and the crack growth behavior was discussed in terms of stress intensity factors…
