TlGaSe 2 layered crystals are studied through dark electrical conductivity, Hall mobility, space-charge limited current and illumination- and temperature-dependent photoconductivity in the temperature ranges 120–350 K, 220–350 K, 260–350 K and 120–350 K, respectively. The Hall effect measurements revealed the extrinsi…
The geological longevity of Lingula, depicted, suggests that the lightly mineralized carbonate-substituted fluorapatite (FAP) shell has remained well-adapted to evolutionary pressures. Contrary to earlier studies, soluble macromolecules isolated from Lingula shells are shown to specifically promote FAP crystallization…
Abstract High quality cubic SBA-16 can be synthesized rapidly at room temperature in 1 h using low surfactant concentrations and has 65% of micropore volume and 5.3 nm of wall thickness on average. The structure integrity of SBA-16 is very sensitive to the acid concentration in gel because of the necessity of moderate…
CdSe/PE2 (PE means polyelectrolyte) multilayers have been successfully synthesized on the surface of SiO2 spheres by using a layer-by-layer technique. The layer structure can be distinguished clearly and the layer thickness can be tailored easily.
Abstract Aniline was oxidized to polyaniline salt using benzoyl peroxide as an oxidizing agent in the presence of acids such as sulfuric, nitric, or hydrochloric acid by aqueous polymerization pathway. Polyaniline salts, their corresponding bases and redoped polyaniline salts were characterized by infrared, electronic…
Invertiert und anelliert: Nach einem [3+2]-Ansatz wurde ein meso-Pentafluorphenyl-substituiertes Pentaphyrin synthetisiert, das einen N-invertierten Pyrrolring und zwei N-anellierte tricyclische Einheiten aufweist. Das Bild zeigt die Struktur im Kristall (F grün, N blau).
Activated endothelial cells (EC) are attractive prime targets for specific drug delivery using drug-carrying magnetic nanoparticles. In order to accomplish EC targeting, the interaction between magnetic particles and resting as well as activated endothelial cells must be characterized and quantified, because it will i…
A series of azobenzene-functionalized poly(alkyl aryl ether) dendrimers have been synthesized and their photochemical and photophysical properties in solution and as thin films have been investigated. Although the photochemical behavior of the azodendrimers in solution indicated that the azobenzene units behave indepe…
Abstract Edible films were cast from solutions of sodium caseinate (NaCAS) and from emulsions of this protein with anhydrous milk fat (AMF). The moisture sorption isotherms, mechanical properties [tensile strength (TS) and elongation] and water vapour and oxygen permeabilities were determined for films based on NaCAS…
The effective workfunctions of single-walled carbon nanotubes of armchair (5,5) and zigzag (9,0) with various geometries have been calculated by first-principles calculations. The results show that the capped and H-terminated zigzag (9,0) carbon nanotubes exhibit a lower workfunction value than the armchair (5,5) nano…
A hexakis-bidentate building block: Tricopper(II) and enneacopper(II) 1,3,5-metallacyclophanes were synthesized by a combination of self-assembly and a rational approach (see scheme). Both complexes exhibit ferromagnetic coupling in the core, through a spin-polarization mechanism.
Abstract The main objectives of this research were to develop whey protein or casein films incorporating zein hydrolysate and also cross-linked by transglutaminase as to well as characterize the physical and mechanical properties of the film. Zein hydrolysate decreased the solubility of the whey protein film (P &l…
Inverted and fused: Meso-pentafluorophenyl-substituted N-confused, doubly N-fused pentaphyrin (see X-ray crystal structure; green: F, blue: N) was synthesized from [3+2] coupling of confused tripyrrane and dipyrromethane dicarbinol, followed by oxidation. Inverted pyrrole rings in pentaphyrin are easily transformed in…
Abstract The miscibility of a phenolic resin with polyhedral oligomeric silsesquioxane (POSS) hybrids and the specific interactions between them were investigated with Fourier transform infrared (FTIR) spectroscopy and wide‐angle X‐ray diffraction (WAXD). An analysis of the morphology and microstructure was performed…
A series of spirooxazine-containing 2,2'-bipyridine ligands and their rhenium(i) tricarbonyl complexes has been designed and synthesized, and their photophysical, photochromic and electrochemical properties have been studied. The X-ray crystal structures of two of the complexes have been determined. Detailed studies s…
Remote functionalized zwitterionic diaminodicyanoquinodimethanes are found to exhibit a dramatic enhancement of light emission in the solid state and when doped in polymer films, as compared to the solution state. Crystal structure analysis of prototypical molecules reveals the role of the remote functionality in the…
Nano-junctions, containing atomic-scale gold contacts between strongly disordered leads, exhibit different transport properties at room temperature and at low temperature. At room temperature, the nano-junctions exhibit conductance quantization effects. At low temperatures, the contacts exhibit Coulomb-Blockade. We sh…
The magnetic properties of thin Pd fcc(001) films with embedded monolayers of Fe are investigated by means of first principles density functional theory. The induced spin polarization in Pd is calculated and analyzed in terms of quantum interference within the Fe/Pd/Fe bilayer system. An investigation of the magnetic…
Abstract Rubber compounds are filled with reinforcing fillers to improve their physical properties. Carbon black and silica have different surface chemistries to each other. Differences in properties of carbon black‐ and silica‐reinforced styrene‐butadiene rubber (SBR) compounds were studied. Variation of properties o…
This article describes a facile solvothermal method by using mixed solvents for the large-scale synthesis of Bi(2)S(3) nanoribbons with lengths of up to several millimeters. These nanoribbons were formed by a solvothermal reaction between Bi(III)-glycerol complexes and various sulfur sources in a mixed solution of aqu…
