the reaction of copper(ii) chloride and zinc(ii) chloride with n-(2-methylphenyl)-3-(1'-salicylaldehydene-2'-imine-ethane)-butanamide(h2l2a) or (mpsb), n-(2-methylphenyl)-3-(1'-(3'-methoxysalicylaldehydene-2'-imine-ethane)-butanamide (h2l2b) or (mpmsb) and n-(2-methylphenyl)-3-(1'-(2'-hydroxyacetylene-2'-imine-ethane)-butanamide (h2l2c) (mphb) leads to th...
an octahedral cobalt(iii) complex, trans-[(me2bpb)co(bzlan)2]clo4 (1), with h2me2bpb = n,n’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, ir, uv-vis, and 1h nmr spectroscopy. the structure of this complex has been determined by x-ray crystallography. the me2bpb2– is a di-anionic tetradentate ligand furnishing a ...
copper nanoparticles were fabricated by electro-reduction of cuso4solution in the presence of cetyltrimethylammonium bromide (ctab) cationic surfactant as an additive through potentiostatic method. the prepared copper nanoparticles were characterized by scanning electron microscopy (sem) and electrochemical methods. the sem images reveal that the nanoparticles with diameters at about 70 n...
under prolonged diabetic conditions, hba1c is produced from normal hemoglobin (hba0) through a non-enzymatic glycosylation or glycation, a process which enhances the hemoglobin susceptibility to be auto-oxidized to methemoglobin (methb). here we are reporting that the non-enzymatic reaction between fructose and methb (methb fructation) induces significant changes in the globin structure and deg...
Investigation of the electrochemical behavior using cyclic voltammetry and detection of [Mn(2+)(thiophenyl-2-carboxylic acid)2 (triethanolamine)] with adsorptive stripping differential pulse voltammetry. The electrochemical behavior of a manganese(II) complex [Mn(2+)(thiophenyl-2-carboxylic acid)2(triethanolamine)] (A) was investigated using cyclic and differential pulse voltammetry in an aceta...
the adsorption of 2-mercaptobenzimidazole (2-mbi) on au(111) has been studied withcyclic voltammetry (cv), in-situ subtractively normalised interfacial ft-ir spectroscopy (sniftirs)and scanning tunnelling microscopy (stm). although adsorbed 2-mbi reduces the interfacial capacityand quenches the characteristic features of the cyclic voltammogram for sulfate adsorption,heterogeneous electron tran...
Thymus is regarded as one of the medicinal species, which according to obtained chromatograms of floral water of Thymus; one of the main components is thymol as strong antioxidant. In this study the appropriate and physically powerful correlation was found between the anti-radical and oxidation potentials. The antioxidant activity of the Thymus was measured by using square wave and cyclic volta...
The MWCNTs-COOH Paste Electrode (MCPE) was successfully used to study the electrochemical behavior of temozolomide in 0.2 M H2SO4 solution, phosphate buffer solution (0.1M PBS, pH 7.4) and 0.1M NaOH solution by Cyclic Voltammetry (CV) technique. The results exhibit that MCPE can remarkably enhance sensing and electrocatalytic activity towards the oxidation and reductio...
A carbon paste electrode (CPE) chemically modified with 1-[4-(ferrocenyl ethynyl)phenyl]-1-ethanone (4-FEPEMCPE) was employed to study the electrocatalytic oxidation of L-cysteine using cyclic voltammetry, differential pulse voltammetry and double potential step chronoamperometry as diagnostic techniques. The diffusion coefficient (D = 7.863 x 10(-6) cm2 s(-1)) of L-cysteine was also estimated ...
