Using a one-pot approach employing true liquid crystal templating on neutral surfactants and simple metal salt precursors, mesostructured, mesoporous silicates have been prepared in which bimetallic nanoparticles are deposited; magnetic properties of PtCo systems so prepared are evaluated.
We report on the impregnation of THF solutions of the low-valent heterometallic cluster NEt(4)[Co(3)Ru(CO)(12)] into two mesoporous silica matrices, amorphous xerogels and ordered MCM-41, and a study of its thermal decomposition into metallic nanoparticles by X-ray diffraction, transmission electron microscopy and in…
Tin-doped indium oxide (ITO) films were deposited on the unheated alkali-free glass substrates (AN100) by reactive magnetron sputtering using an indium–tin alloy target with an unipolar pulsed power source feeding 50 kHz pulses and a plasma control unit (PCU) with a feed back system of oxygen plasma emission intensity…
The electrical properties of a novel, cross-linked polycarbosilane, which is thermally stable up to , were investigated as a potential interlayer dielectric for advanced interconnect technology. This polycarbosilane is derived from a cyclolinear precursor polymer, which was spin-coated from xylene solution and cured a…
Shape memory alloys possess the ability to return to a preset shape by undergoing a solid state phase transformation at a particular temperature. This work reports on the development and testing of a low temperature thermal conduction switch that incorporates a NiTiFe shape memory element for actuation. The switch was…
Preface. List of Authors. 1 Nanotechnology and Tissue Engineering: The Scaffold Based Approach (Lakshmi S. Nair, Subhabrata Bhattacharyya, and Cato T. Laurencin). 1.1 Overview. 1.2 Introduction. 1.3 The Importance of Scaffolds in Tissue Engineering. 1.4 Structure and Functions of Natural Extracellular Matrix. 1.5 Appl…
In this paper maleic anhydride grafted polypropylene, MAPP (GR-205) was used as a coupling agent for the PP-cellulose (derived from oil palm empty fruit bunch fiber) and PP-oil palm empty fruit bunch fiber (EFBF) biocomposites. Different sets of biocomposites were prepared by blending PP-cellulose and PP-EFBF at a fix…
According to X-ray single-crystal structure analysis, {[Cu(II)(en)2]2[Cu(I)2(CN)6]}[Cu(II)(en)2]2[Cu(I)(CN)3]2.2H2O contains copper in four different coordination environments: trigonal planar, square planar, square pyramidal and tetrahedral. The different coordination geometries of copper were investigated by quantum…
The reaction of sodium phenolate and Fe(HCTPPH)Br assembles a dimeric iron(III) complex with a channel-like solid state packing; the intramolecular iron-to-iron distance of 8.864 A is the longest among the available N-confused porphyrin dimeric complexes.
The synthesis of the first meso-meso linked core modified smaragdyrins with unusual single photon properties is reported.
Multilayered nanotubes were electrodeposited in nanoporous membranes under pulsed potential conditions from a single electrolyte. Giant magnetoresistance (GMR) measured with the current applied perpendicular to the plane of the layers was obtained at room temperature. This is the first demonstration of GMR in a nanotu…
The aim of the present study was to compare results obtained using the manual point-counting method with results obtained using the semi-automated segmentation method, in the quantitative evaluation of histological sections by light microscopy. The tongues of 40 rats (Ratus norvergicus) were processed using the paraff…
The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups is achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and efficient four step route is reported. The tosylate of hydroxymethyl-ET, r…
The synthetic conditions for the isolation of the iron-molybdenum nanocluster FeMoC [HxPMo12O40 [subset]H4Mo72Fe30(O2CMe)15O254(H2O)98], along with its application as a catalyst precursor for VLS growth of SWNTs have been studied. As-prepared FeMoC is contaminated with the Keplerate cage [H4Mo72Fe30(O2CMe)15O254(H2O)9…
Reversible magneto-switchable quantum charging of a Au nanoparticle array associated with a Au electrode is observed in the presence of hydrophobic magnetic nanoparticles attracted to the functionalized electrode surface.
The electrochemical properties of porphyrin-appended dendrimers containing 2-, 4-, 8-, 16-, 32- and 64-porphyrin macrocycles in their free-base and zinc(II) forms have been investigated. Both series gave diffusional based voltammetric responses in dichloromethane. There was minimal effect of dendrimer generation on th…
A new type of coating involving a layer-by-layer technique has been recently reported. This coating is composed of a polyelectrolyte multilayer film that confers specific properties on surfaces to which it is applied. Here, we studied the applicability of such a technique to the coating of oral prostheses, by first te…
A series of biodegradable poly (ester amide)s composed of sebacic acid, dodecanediol and different ratios of the stereoisomers of L- and D-alanine were synthesized for applications in drug delivery systems. Microspheres loaded with diclofenac sodium salt, triclosan and clofazimine were prepared with the solvent evapor…
Abstract For certain commercial applications of polypyrrole (PPy), an enhancement of the electrical conductivity of the material is the key to industrial success. In this paper it will be shown that raw PPy with high conductivity (>150 S/cm) can be obtained in very good yield (>90%) by appropriate selection of b…
