A mild, facile one-step synthetic strategy for the preparation of size- and shape-controlled silver nanoparticles (AgNPs) is presented. The high degree of size- and shape-control of these AgNPs is achieved by the use of triazole sugar ligands scaffolded by a central resorcinol ether core. Both the triazoles and the resorcinol ether core mediate the nucleation, growth, and passivation phases of ...

Electrooxidation of methanol was realised on platinum and perchlorate anion doped polypyrrole film electrodes in acidic media. A systematic kinetic investigation was performed and optimum experimental conditions for the preparation of the electrocatalytic system were determined. The presence of ClO4 − anions was confirmed by XPS analysis of the doped polymer matrix. © 2001 Elsevier Science B.V....

A purification procedure for the preparation of chicken liver arginase in a homogeneous form is presented. The enzyme hydrolyses both arginine and argininic acid. Kinetic analysis reveals that the enzyme binds arginine when the amino group is protonated or unprotonated; however, the unprotonated form seems to be hydrolysed more rapidly. The enzyme exchanges with the medium approx. 1.6Mn2+ ions ...

The reversibility of the NAD+ kinase reaction was established, and the kinetic parameters of the rate equation in the reverse direction were determined. The equilibrium constant of the reaction was determined by using the purified pigeon liver enzyme and radioactively labelled nicotinamide nucleotides. The relationship between kinetic parameters of the forward and reverse reactions is in reason...

Kinetic phase diagrams in technical alloys at different solidification velocities during rapid solidification are of great importance for guiding the novel alloy preparation, but are usually absent due to extreme difficulty in performing experimental measurements. In this paper, a phase-field model with finite interface dissipation was employed to construct kinetic phase diagrams in the ternary...

In the course of studies by Keilin and Hartree (1) on succinic oxidase preparation of heart muscle particles, it was observed that the kinetics of reduction of cytochrome b were not in accord with some rather fundamental criteria that must be met for an electron-transferring component in the respiratory chain (2). On the other hand, studies of the kinetics of cytochrome b in intact yeast cells ...

Background and aims: From the past studies, it has been proved that consumption of heavy metals by humans may cause several chronicle problems like cancer, kidney and liver damage, high blood pressure and low blood pressure problems and etc. So, it has become very crucial to remove these heavy metals from industrial wastewater. The aim of this study was to find out a low cost a...
