The reaction of 2,3-bis(2-hydroxybenzylideneimino)-2,3-butenedinitrile (H2L) and Ni(CH3CO2)2·2H2O affords a nickel(II) complex [NiL] 1, a new molecular electrocatalyst, which has been determined by X-ray crystallography. Electrochemical studies show that complex 1 can catalyze hydrogen evolutio...
Two molecular electro-catalysts based on nickel complexes, [Ni(mnt)2]n − (n = 2 (1) and 1 (2)) are formed by the reactions of NiCl2·6H2O, Na2(mnt) and [BzPyN(CH3)2]Br or [4-ClBzPyN(CH3)2]Br (BzPyN(CH3)2 = 1-benzyl-4-(dimethylamino)pyridinium, mnt = 2.2-dicyanoethylene-1.1-dithiolate, and 4-ClBz...
The N-phenylpyridin-2-ylmethanimine ligand, HL reacts with NiCl2·6H2O to afford a water soluble nickel(II) complex, [Ni(HL)2Cl2] 1. Electrochemical studies exhibit that this complex acts as an electrocatalyst for water reduction to hydrogen from a neutral water (pH 7.0) with a TOF of 970.45 mol...
ObjectiveTo evaluate the effect of different surface treatments of nickel chrome (NiCr) with the type of metal primer monomers on the conventional tensile bond strength (CTBS) of resin cement.
Fifty years ago, when this journal was founded, organometallic chemists could not have imagined that common small molecules such as dinitrogen and especially dihydrogen could function as ligands. Dihydrogen has long been vital in catalytic processes such as hydrogenation and conversions of organ...
This article is discussing the growth of a new class semi-organic nonlinear crystal (4-sulfo benzene aminium) tri nickel(II) bis(dihydrogen phosphate) (4-STNBDHP) grown by slow evaporation solution growth technique at ambient temperature. The purity of the crystal was achieved by recrystallizati...
The interaction of the non-steroidal anti-inflammatory drug sodium diclofenac with CoCl2 in the absence or presence of the nitrogen-donor ligands 2,2′-bipyridine, 1,10-phenanthroline, 2,2′-bipyridylamine, pyridine or imidazole resulted in the formation of six mononuclear Co(II) complexes. The ...
Three-dimensional Bi2MoO6/TiO2 array was fabricated by decorating TiO2 nanorods (NRs) with Bi2MoO6 nanosheets (NSs). Compared with pristine TiO2 NRs and Bi2MoO6 NSs, the obtained Bi2MoO6/TiO2 heterostructure showed an excellent photoelectrochemical (PEC) performance. The photocurrent density rea...
The presence of cobalt(II) in wastewater is an emergent concern because of its toxicity at elevated concentration. Co(II) is a non-biodegradable, carcinogenic and mutagenic pollutant released from natural, industrial and manmade sources. In recent years, the control of water that has been pollut...
A crystalline mesoporous cobalt phosphate (meso-CoPi) electrocatalyst is prepared using liquid crystal template of non-ionic surfactant of Brij®78. The physicochemical investigations of the electrocatalyst executed by surface area analyzer, XRD, transmission electron microscope submits creation ...
Interaction of nucleotides and metals has been largely studied since they have biological importance. Divalent complexes of inosine 5'-monophosphate with cobalt(II) (IMP-Co), nickel(II) (IMP-Ni), copper(II) (IMP-Cu) and cadmium(II) (IMP-Cd) have been characterized by elemental analysis and ...
A new phase of cobalt(II) hydroxyl phosphate γ-Co2(PO4)(OH) has been successfully synthesized through a conventional hydrothermal method. This compound crystallizes in the trigonal system of space group P31m, showing a warping two-legs spin ladder chain structure arranged in an unusual triangul...
Electrodeposited cobalt phosphate has been reported as a valid alternative to noble metals as an electrocatalyst for the Oxygen Evolution Reaction (OER). In parallel, Atomic Layer Deposition (ALD) is increasingly being used in (photo)electrocatalytic applications. In this contribution we report ...
In this work, a new type of luminescent temperature sensor based on the Sn2+→Mn2+ resonance energy transfer is designed, which shows great potential in high temperature optical thermometry. Using the micro-sized Sn2+/Mn2+:α-Sr2P2O7 phosphor fabricated by carbon reduction method as optical ther...
Luminescent properties of manganese(II) phosphates prepared by thermal dehydration of Mn(H2PO4)2 · 2H2O have been studied. The emission spectrum consists of two bands whose relative intensity and spectral position depend on the chemical and crystalline structure of phosphates. The different cou...
Norcocaine is the N-demethylated metabolite of cocaine. It is present in the CNS and is reported to be pharmacologically active. The present study was designed to evaluate the cardiovascular actions of norcocaine following central administration. Wistar Kyoto (WKY) rats were anesthetized with pe...
We examined the effects of intravenously administered cocaine and norcocaine on the haemodynamics, the plasma immunoreactive atrial natriuretic peptide (ANP), the N-terminal peptide of proANP (NT-ANP) and the plasma catecholamine levels in conscious, chronically cannulated Sprague-Dawley rats. C...
In order to further explore the importance of cocaine's bridge nitrogen atom in binding to the dopamine transporter (DAT), we have synthesized the previously known racemic 8-oxa-norcocaines 3–6 in which the nitrogen atom has been replaced by oxygen. Additionally, to avoid incorrect interpr...
A quantitative analytical procedure for the determination of cocaine, benzoylecgonine and cocaethylene and norcocaine in hair has been developed and validated. The hair samples were washed, incubated, and any drugs present were quantified using mixed mode solid-phase extraction and liquid chroma...
