The experimental electron density rho(r) of the two isomorphic salts KMnO(4) and KClO(4) was determined by a multipole analysis of accurate X-ray diffraction data at 120 K. The quantum theory of atoms in molecules was applied to rho(r) and to its Laplacian nabla(2)rho(r). The bonds were characterized using the topological parameters at the bond critical points of the density rho(r), nabla(2)rho...

Simple, accurate and precise spectrophotometic methods for quantitative determination of four drugs viz., Levofloxacin (LEV), Moxifloxacin (MOX), Pseudo Ephidrine (PSE), Torsemide (TOR) have been developed based on oxidation of the drugs by alk.KMnO4. Kinetics of the oxidation reaction is followed spectrophotometrically, as one of the reaction product, Mn(VI), absorbed at 610 nm. Initial rate a...

A simple and sensitive chemiluminometric method using flow injection (FI) is developed for the determination of carvedilol, based on the reaction of carvedilol with tris (2, 2'-bipyridyl) ruthenium (II), and KMnO4 in sulfuric acid medium. Under the optimum conditions; the chemiluminescence (CL) intensity is a linear function of carvedilol concentration over the range of 0.04-1.0 µg ml(-1) (9.8 ...

We report experimental studies of polarization dependence in resonant soft X-ray emission of 3d transition metal compounds. In metal 2p resonant soft X-ray emission spectra of 3d0 systems, transition to the bonding and antibonding states between 3d0 and 3d1L configurations shows polarization dependence. In TiO2, the polarization dependence is drastic, whereas it is slightly weak in ScF3 and ext...

BACKGROUND: The conventional solution-phase Chemical Cleavage of Mismatch (CCM) method is time-consuming, as the protocol requires purification of DNA after each reaction step. This paper describes a new version of CCM to overcome this problem by immobilizing DNA on silica solid supports. RESULTS: DNA test samples were loaded on to silica beads and the DNA bound to the solid supports underwent ...

Renewable energy is an increasing need in our society. Microbial fuel cell (MFC) technology represents a new technology for the regeneration of electricity from what would otherwise be considered waste and can be a vital candidate for energy in this respect. Electricity directly generated by using bacteria while accomplishing wastewater treatment in MFC processes. The present study deals with p...

A convenient approach for oxidation of structurally diverse alcohols has been developed using KMnO4 as oxidant agent in the presence of a catalytic amount of Al2O3 in aqueous acetonitrile. In this method various alcohols generally afforded the corresponding carbonyl compounds directly in good to high yield under ultrasound irradiation conditions. It shows that this kind of catalysis system is v...

This experiment target measuring soil properties (pH, EC and OC), nutrient (N, P, K S) the correlation study between availability. Six different locations in Havalbag block, Almora district of Uttarakhand, were sampled for (0-15cm depth). Nitrogen, Phosphorous, Potassium Sulphur examined using known conventional methods. Available Nitrogen was by alkaline KMnO4 method, extractable available CaC...
