The use as an embedding resin for ultrathin sectioning of a cross-linked triple copolymer of N-vinylpyrrolidone, acrylonitrile, and ethylene glycol dimethacrylate is described. The first of these components is miscible with water, in all proportions, and can be used as a dehydrating agent, or, alternatively, ethanol may be used in the standard way. Polymerization is carried out at 37 degrees C ...

Sir,?I request the favour of your kindly giving place to the following in your esteemed paper : ? In an epidemic of cholera in this town I have been trying intravenous injection of hypertonic salt solution combined with permanganates internally with a fair amount of success. In some cases there were certain phenomena which I am unable to explain and I hope some of your kind readers might favour...

The selective oxidation of alcohols is an important reaction in organic synthesis and chemical industry, e.g. in the production of fine chemicals like aldehydes, ketones or acids. A valuable strategy to avoid harmful stoichiometric oxidizing agents such as chromates, permanganates or chlorinated epoxides producing huge amounts of wastewater and by-products [1] is the aerobic oxidation in the li...

The residues of persistence potentially toxic organic compounds polyaromatic hydrocarbons (PAHs) were measured in 13 species of edible vegetables collected from Great Cairo governorate (Egypt). And the efficient role of washing by oxidizing agents hydrogen peroxide (H O ), potassium permanganates (KMnO ) 2 2 4 and midribs of cabbage leaves solutions on the elimination of PAHs from contaminated ...

The efficiency of permanganates to inhibit the scale deposit captured attention for more investigation on their role as corrosion inhibitor. In this article, effect permanganate inhibitor 316L stainless steel in NaCl solution is investigated. potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) have been performed by varying electrode stirring speed, concentration ions,...
