Imidazoline binding sites or imidazoline/guanidinium receptive sites (IGRS) recognize bioactive endogenous substances and a variety of pharmacologically active compounds containing imidazoline or guanidinium moieties. The family of imidazoline binding proteins consists of multiple membrane-assoc...
The self-assembled (SA) film of 2-mercapto-5-methyl-1,3,4-thiadiazole on the cathodic (McMT) was prepared on iron surface. The film was characterized by electrochemical impedance spectroscopy (EIS), electrochemical polarization, X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spe...
The effects of thioureido imidazoline and NaNO2 on passivation and pitting corrosion of X70 steel in acidic NaCl solution were studied. The addition of thioureido imidazoline promoted passivation of the steel in the NaCl-NaNO2 solution, but the pitting potential decreased, which was attributed t...
Cyclopentadienyl- and methylcyclopentadienyl-(triphenylphosphine)gold(I) and cyclpentadienyl(triethylphosphine)gold(I) have been characterized by infrared and variable temperature proton magnetic resonance spectroscopy. The compounds are suggested to have monohapo (i.e. σ-bonded) rings, in cont...
The compound C5H5Cu P(C2H5)3 has been prepared by the reaction of cyclopentadiene and triethylphosphine on cuprous oxide; it is a white crystalline solid stable to water.The compound (C5H5)2Hg has been prepared by the reaction of mercuric chloride with sodium cyclopentadienide in tetrahydrofuran...
The layered group Vb ditellurides MTe2 (M=V, Nb, Ta) were intercalated with Cu (a) electrochemically and (b) via an autoclave route, forming new compounds of the compositions CuxVTe2 (x=0.85–0.92), CuxNbTe2 (x=0.78–1.00) and CuxTaTe2 (x=0.79–0.95). While for CuxNbTe2 a composition of x=0.69 w...
Polymer brushes are known to form highly efficient lubricating layers for a broad range of contacting surfaces in water. Here we focus on brushes of poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) polymers that are end-anchored to the substrate at a high density. We show that the friction ...
Compounds of lithium oxide, hydroxide and carbonate, mixed with silver, were prepared for use as a cathode in caesium-sputter ion source. The intention was to determine the procedure which would produce the highest intensity negative lithium beams over extended period and with maximum stability....
Following the accident at the Fukushima Daiichi Nuclear Power Plant in 2011, radioactive cesium was released into the environment in large amounts and heavily contaminated drinking water in Fukushima and neighboring prefectures. In this research, the capability of nanoscale zero valent iron (nZV...
A study on the hydrofluorination of epoxyaldonolactones with Bu4N+H2F3− (1) under solid-liquid PTC and homogeneous conditions has been performed. Unsubstituted 5,6-epoxy-hexono-1,4-lactones 2a give the corresponding fluorohydrins in high yield using catalytic amounts of 1 and an excess of solid ...
The physical and chemical properties of nanocrystals can be modified by changing the ligands attached at their surfaces. A ligand exchange procedure with ammonium polysulfides has been developed to replace the native ligands on cubic zinc sulfide nanocrystals. Several mixtures of polysulfides in...
Although lithium sulfur batteries (LSBs) possess extremely high specific capacity and ultrahigh energy density, the low conductivity and severe shuttle effect greatly restrict its practical application. Herein, we report a facile strategy to overcome the problems via a double-layer structure, in...
Lithium-sulfur battery is regarded as one of the most promising candidates for next-generation energy storage devices due to its high theoretical capacity and energy density, howbeit the shuttle effect and sluggish reaction kinetic behavior of solute polysulfides hamper its practical application...
Polysulfide polymers are known as sealants. Good adhesion and elastic properties are the significant features of sealants. The epoxy polysulfide resin due to end epoxy group in the chain of polysulfide polymer has the both properties of epoxy and polysulfide resins These dual properties, along w...
The structure of the N,N-dimethylthioformamide (DMTF) solvated gallium(III) ion has been determined in solution by means of extended X-ray absorption fine structure (EXAFS) spectroscopy. The gallium(III) ion is four-coordinate in tetrahedral fashion with a mean Ga–S bond distance of 2.233(2) Å ...
Model wine solutions containing organic acids, individually or combined, and iron(III), were exposed to light from fluorescent lamps or stored in darkness for four hours. (−)-Epicatechin was then added, and the solutions incubated in darkness for 10 days. Browning was monitored by UV–visible ab...
A new series of Iron (III) complexes of general formula [Fe(Hdmg)2(Gua)X]nH2O where (Hdmg = dimethylglyoximato monoanion, Gua = Guanine, X = Cl, Br or I) have been prepared and characterized by elemental analysis, conductivity, infrared spectra and electronic spectra. The molar conductance data ...
The thermal and thermo-oxidative decompositions of NH4FePO4·H2O were studied by means of a combination of classical thermal analysis techniques (TG and DSC) with MS and powder XRD analysis. The experiment was run in two different (inert and oxidizing) atmospheres. In an inert (N2) atmosphere, t...
In this paper we report synthesis of aqueous based gold coated iron oxide nanoparticles to integrate the localized surface plasma resonance (SPR) properties of gold and magnetic properties of iron oxide in a single system. Iron oxide-gold core shell nanoparticles were stabilized by attachment of...
An efficient catalyst made of bismuth, iron and graphene oxide composite was developed for the reduction of nitroarenes with hydrazine hydrate to afford corresponding anilines. We found that the bismuth and graphene remarkably promoted the activity of iron oxide catalyst, so that a mixture of fe...
