X-ray photoelectron spectroscopy analysis of electronic states in the oxide layer on an ultradisperse copper surface

X-ray photoelectron spectroscopy (XPS) is used to study the electronic states of copper oxide covering a thin (2.0 ± 0.5 nm) layer of ultradisperse copper. A reduction in the thickness of the CuO layer is found to cause extremal behavior in the XPS spectrum parameters as opposed to their monontonic variations for CuO nanoparticles. This behavior is explained by the competition of two factors which affect the system under study: the dimensions of the substrate material and the electrostatic field in it.

Empirical calculation of fatty acid and glycerol composition in evaluating drug quality

Based on empirical indices of the composition and quality of drugs prepared from oil-bearing plant material, an algorithm for calculation of the fatty acid and glycerol composition is developed that can be used for screening evaluation of potential counterfeits and identification of poor-quality products.     

Preparation of tritium-labeled prostaglandin E3

Conditions for the biosynthesis of PGE₃ from eicosa-5,8,11,14,17-pentaenoic acid using an enzyme system isolated from ram seminal vesicles have been worked out. Tritium-labeled PGE₃ has been obtained in good yield with a molar radioactivity sufficient for performing many biological investigations.Institute of Molecular Genetics, Academy of Sciences of the USSR, Moscow.
