Resource shortage is a major problem in our world. Nuclear energy green and because of this its high density, it has been attracting more attention during the last few decades. Uranium valuable nuclear fuel used majority power plants. More than one thousand times uranium exists oceans, at very low concentrations, present terrestrial ores. As demand for generation increases year-on-year, access ...

Based on quantitative precipitin theory, it is possible to identify some sugar groupings in a polysaccharide molecule by immunochemical cross-reactions. The structural features of some type-specific pneumococcal polysaccharides are shown and the reasons for their cross-reactions in different antipneumococcal sera are discussed. Verification of these conclusions was made by studying the cross-re...

The structures of the organomercury compounds have been reviewed from the point of view of the secondary bonds which mercury atom forms with the surrounding atoms. These bonds, though rather labile, exhibit a definite influence on the crystal structure which is manifested in a peculiar coordination around the mercury atom. This influence has to be studied systematically since the mercury coordi...
