The article presents the effect of attapulgite (ATT) and its synergic action with carbon or silica on the thermal properties and flammability of cross-linked styrene–butadiene rubber. It has been shown that ATT is active filler improving the thermal and mechanical properties of composites containing this aluminosilica…
We report surface potential maps of few layered graphene oxide films on different substrates. Kelvin probe force microscopy images reveal that the surface potential decreases in steps with increasing number of layers on the substrate until five layers are reached, where it saturates to a constant value. This intrinsic…
195 Pt solute diffusion coefficients in undoped single‐crystal rutile TiO 2 have been determined parallel to the c ‐axis over the temperature range of 1073–1523 K and oxygen partial pressure of 101 kPa. This has yielded the following temperature dependence: urn:x-wiley:00027820:media:jace12130:jace12130-math-0001 On t…
We developed a simple approach to design and fabricate precisely controlled coiled nanofibers via the micromanufacture of electrospun nanofibers. The fabrication set-up was specially designed so that one stream of polyvinyl pyrrolidone (PVP) sol with ferric nitrate was electrospun into a fiber bundle. This bundle acte…
Abstract In biological systems, noncovalent interactions of molecular building blocks such as lipids, proteins, and nucleic acids play important roles in creating diverse complex structure and dynamic function. Inspired by such biological systems, we have designed a variety of functional supramolecular materials on th…
Abstract Polystyrene (PS)‐incorporated polyhedral oligomeric silsesquioxanes (POSS) organic–inorganic hybrid graft copolymer could be achieved by click coupling reaction between alkyne groups in POSS and azido groups in PS via “graft onto” strategy. Alkyne‐functionalized POSS was synthesized via thiol‐ene facile click…
Abstract The aim of this work was to study the effect of different organomontmorillonite on the structure and properties of room‐temperature vulcanized silicone rubber (RTV) composites. Quaternary ammonium salts (QAS) and hyperbranched QAS were used as intercalation agents to treat Na + ‐montmorillonite and formed two…
Sulfolobus solfataricus P2 is a thermoacidophilic archaeon that metabolizes glucose and galactose via an unusual branched Entner-Doudoroff (ED) pathway, which is characterized by a non-phosphorylative (np) and a semi-phosphorylative (sp) branch. However, so far the physiological significance of the two pathway branche…
A grain-oriented electrical steel has a significantly low iron loss by selective growth of grains with {110}< 001> orientation called as Goss orientation. The selective growth of Goss grains is generally attained by making use of a phenomenon termed ‘secondary recrystallization’. We have already investigated primary r…
We have shown that the superconducting properties of FeSe0.5Te0.5thin films are strongly dependent on the growth conditions and, in particular, the in-plane lattice constant of the substrate influences the crystallographic lattice parameters of the films, affecting the strain and is responsible for strong enhancements…
The enhancement in tensile properties of a Cu–2.0 mass%Ni–0.5 mass%Si–0.1 mass%Zr alloy without reducing its electrical conductivity is attempted by combining both accumulative roll-bonding (ARB) and cryo-rolling with aging treatment. The grain sizes of the alloy pre-aged at 450°C and ARB-processed in six cycles (P-AR…
Room-temperature (atmospheric-pressure) electrical conductivity measurements of wafer-scale, large-area suspended (few layer) graphene membranes with areas up to 1000 μm2 (30 μm × 30 μm) are presented. Multiple devices on one wafer can be fabricated with high yield from the same chemical vapor deposition grown graphen…
We have studied quantum transport in graphene nanoribbon tunnel field-effect transistors. Unlike other studies on similar structures, we have included dissipative processes induced by inelastic electron-phonon scattering and edge roughness in the nanoribbon self-consistently within a non-equilibrium transport simulati…
First principles calculations of the linear and nonlinear optical properties are carried out for three series of one-dimensional ruthenium(II) ammine complexes with one pyridyl pyridinium ligand containing different numbers of C 2 H 2 units or the (CH═CH)—Ph—(CH═CH) linker. The substitution effects upon introducing on…
We review recent results from extensive simulations of the crystallization of athermal polymer packings. It is shown that above a certain packing density, and for sufficiently long simulations, all random assemblies of freely-jointed chains of tangent hard spheres of uniform size show a spontaneous transition into a c…
This work revealed that the solid solution compounds of Sr 2 − x Ba x Nb 2 O 7 are promising lead‐free materials for high‐temperature piezoelectric sensor application. These compounds were confirmed as ferroelectric materials with high Curie points ( > 900°C) by their piezoelectric activity after poling, ferroelect…
Effective control of room-temperature electroluminescence of n-ZnMgO/p-GaN light-emitting diodes (LEDs) over both emission intensity and wavelength is demonstrated. With varied Mg concentration, the intensity of LEDs in the near-ultraviolet region is increased due to the effective radiative recombination in the ZnMgO…
In this study, cadmium sulphide (CdS) nanorods doped ferroelectric liquid crystal (FLC) sample cells have been prepared and studied. A memory effect has been observed in CdS nanorods (≤0.3 wt%) doped FLC mixture and confirmed by textures, dielectric and optical studies. The addition of nanorods increases the memory be…

Several first- or second-generation Janus-type codendrimers that combine promesogenic bent-core and rodlike molecular segments have been synthesized by the versatile CuAAC reaction and the materials have been characterized by POM, DSC, XRD, and SHG studies. Depending on the ratio between the number of rod- and bent-co…
