International Journal of Electrochemical Science, 2012 The method for reliable determination of Cd(II) by square wave adsorptive cathodic stripping voltammetry was done. The technique involves an interfacial adsorption of Cd(II) as Cd-cupferron complex on a Nafion-coated bismuth film electrode and subsequent

Nanomaterials Developed by Processing Iron Coordination Compounds for Biomedical Application
Journal of Nanomaterials, Volume 2019, Issue 1, 2019., 2019 The iron oxides, widespread in nature, are used in numerous applications in practice due to their well‐known properties. These properties can be modified by size lowering at nanoscale. Some applications, such as biomedical, require a rigorous selection of nanoparticles by size, shape, and surface functionality.

Oxidative Medicine and Cellular Longevity, Volume 2016, Issue 1, 2016., 2016 Nitroxyl (HNO), the one‐electron reduced form of nitric oxide (NO), shows a distinct chemical and biological profile from that of NO. HNO is currently being viewed as a vasodilator and positive inotropic agent that can be used as a potential treatment for heart failure.

Journal of Nanotechnology, Volume 2012, Issue 1, 2012., 2012 HDA‐capped ZnO nanoparticles were prepared by solvothermal method using solvents of different polarities. A number of parameters were kept constant such as temperature, pressure, time, and pH while solvents were varied, that is, water, ethanol, and acetone. The TEM was used for the structural properties and morphologies such as spheres, mixture of rods,

Speciation of Chromium in Soil and Sludge in the Surrounding Tannery Region, Ranipet, Tamil Nadu
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 The distribution and mobility of chromium in the soils and sludge surrounding a tannery waste dumping area was investigated to evaluate its vertical and lateral movement of operational speciation which was determined in six steps to fractionate the material in the soil and sludge into (i) water soluble, (ii) exchangeable, (iii) carbonate bound, (iv ...

Journal of Analytical Methods in Chemistry, Volume 25, Issue 6, Page 133-140, 2003., 2003 The development of a dedicated automated sequential‐injection analysis apparatus for anodic stripping voltammetry (ASV) and adsorptive stripping voltammetry (AdSV) is reported. The instrument comprised a peristaltic pump, a multiposition selector valve and a home‐made potentiostat and used a mercury‐film electrode as the working electrodes in a thin ...
