Long continuous yarns consisting solely of carbon nanotubes may be the future of specialty composites requiring unique multi-functional properties. Many of such yarns were incorporated in a hybrid composite here, to demonstrate for the first time, their effect on increasing the electrical conductivity of an otherwise…
Self-assembly of five two-dimensional hydrogen-bonded honeycomb grids bearing the rosette motif has been conducted with the guanidinium cation and various anionic components as the building blocks, tetraalkylammonium ions being employed as the interlayer templates. The sinusoidal supramolecular guanidinium-carbonate (…
Present results demonstrate that the redox potential and hence the chemical reactivity of a solute dissolved in a polymer-surfactant supramolecular assembly, considered as a nanoreactor, can be tuned substantially by changing the composition of the supramolecular assembly. It is understood from detailed study that, on…
Ti-Ta alloys are potentially interesting for many applications including chemistry industries, marine environment and biomedical devices. In this study, the Ti-Ta alloys were synthesized by cold crucible levitation melting (CCLM) in the whole range of composition. The different microstructures were characterized by X-…
A high-temperature X-ray diffraction study revealed that brownmillerite-type Ca(2)Al(2)O(5) transforms to an incommensurately modulated structure at elevated temperatures. Single crystals of Ca(2)Al(2)O(5) were synthesized in an end-loaded piston cylinder press at 2.5 GPa and 1273 K. The diffraction pattern observed a…
Abstract Commercially available organoclay (Closite 30B) was modified by using 3‐aminopropyltriethoxysilane (APS) via a silylation reaction. Sodium clay (Closite Na) was treated by APS directly as a control. Such modified clays were further melt‐compounded with polybutylene terephthalate (PBT). The morphology and prop…
We report on structural, magnetic and electronic properties of Co-implanted TiO2 rutile single crystals for different implantation doses. Strong ferromagnetism at room temperature and above is observed in TiO2 rutile plates after cobalt ion implantation, with magnetic parameters depending on the cobalt implantation do…
This study investigates the feasibility of a novel nanocomposite (GC/Ag) of a genipin-crosslinked chitosan (GC) film in which was embedded various amounts of Ag nanoparticles for wound-dressing applications. In situ UV-vis results revealed that adding chitosan solution did not affect the characteristics of Ag nanopart…
Abstract It was for the first time we attempted to develop zinc and cadmium incorporated linseed oil based poly(esteramide‐urethane) [Zn/Cd‐LPEAUr], and investigated their structure, mechanism, and properties. The resin was synthesized in situ by the reaction of linseed oil derived fatty amide diol [HELA], divalent zi…
Abstract An attempt was made to synthesize polyurethane (PU)/organoclay nanocomposite foams with high thermal insulation properties. The organoclay was modified by polymeric 4,4′‐diphenylmethane diisocyanate (PMDI) with a silane coupling agent. The structure of the organoclay‐modified PMDI with the silane coupling age…
Abstract Multiphased mixed crystals of NaCl, KCl and KI were grown by the melt method, for the first time. Densities and refractive indices of all the grown crystals were determined and used for the estimation of the composition in the crystal. Atomic absorption spectroscopic measurements were done to estimate the met…
Abstract The graft polymerization of 2‐Hydroxyethyl acrylate, 2‐Hydroxyethyl methacrylate, and N ‐vinylpyrrolidone onto chitosan in aqueous solution initiated by γ‐ray irradiation was carried out. The effect of various conditions such as the absorbed dose, concentration of monomer, and solvent on grafting was investig…
Abstract This work describes the properties of plastics made from partially denatured proteins produced by the animal coproduct (rendering) industry and these plastics' fabrication. Specifically, plastic samples from partially denatured feathermeal protein were successfully produced by a compression‐molding process. T…
Abstract Carbazole containing ligand dendrons are designed based on second generation polybenzyl ether dendrons (2GPO). This is subsequently used for directly synthesizing and capping CdSe nanoparticles in contrast to ligand exchange for introducing functionality. The stable hybrid CdSe‐2GPO quantum dot nanoparticles…
Abstract The paper studies the utilization of attenuated total reflectance–Fourier transformed infrared (ATR–FTIR) and Raman spectroscopy to investigate isothermal semi‐batch precipitation of a model compound, L ‐glutamic acid. ATR–FTIR spectroscopy was mainly used for in‐line monitoring of the solution phase and Rama…
This work reports on the fabrication and characteristics of n-ZnO/p-GaN and n-ZnO/n-MgZnO/n-ZnO/p-GaN heterojunction light emitting diodes (LEDs). Both devices exhibited diode-like rectifying current-voltage characteristics. Room temperature electroluminescence (EL) spectra for both LEDs consisted of dominant emission…
Lösliche Modellverbindung: Eine molekulare Entsprechung der kürzlich vorgestellten Wasserstoffspeicherform [{Ca(NH2BH3)2}n] wurde untersucht. Der in Kohlenwasserstoffen lösliche Calcium-Amidoboran-Komplex spaltet bei sehr niedrigen Temperaturen von 20–40 °C spontan H2 ab (siehe Schema). Als Zersetzungsprodukt entsteht…
A short, high-yielding route to omega-dithiafulvenylpolyenals (1) via the corresponding iminium salts (2) and starting from trimethyl-1,3-dithiolium tetrafluoroborate is reported. The Knoevenagel reactions of either 1 or 2 with isoxazolone-containing acceptors afford merocyanines 7 and 9, in a process that is often ac…
The fasciculation and elongation protein Zeta 1 (FEZ1) is the mammalian orthologue of the Caenorhabditis elegans protein UNC-76, which is necessary for axon growth. Human FEZ1 interacts with Protein Kinase C (PKC) and several regulatory proteins involved in functions ranging from microtubule associated transport to tr…
Wasserabweisend: Die Selbstorganisation von Oligo(p-phenylenvinylenen) (OPVs) auf Kohlenstoffnanoröhren (CNTs) verleiht diesen Dispergierbarkeit in organischen Lösungsmitteln, sodass sie zur Beschichtung von Glas-, Metall- und Glimmeroberflächen genutzt werden können. Dabei resultieren superhydrophobe selbstreinigende…
