Spatial and Electronic Structure of the Pyrene Molecule, Tripaflavin Cation and Eosin Anions As a Prerequisite for Interpreting Their Solid-phase Fluorescence

At the B3LYP/6-311++G(d,p) level of theory, involving the NBO analysis, the spatial and electronic structure of the pyrene molecule, tripaflavin cation, eosin monoanion and dianion has been computed. The results obtained will offer a framework for interpreting the peculiarities of the above species solid-phase fluorescence.

Exploration of Possibilities for Organic Selenides and Dihydroselenochromilium Salt Interaction with Diphenylpicrylhydrazyl

Higher fungi – basidiomycetes play significant role as food and biological subjects for establishing the regularities of the living systems’ operation, development and response to the different-nature effectors impact. Insufficient activity of the living organisms’ antioxidant system interfering the ability of overcoming the negative consequences of oxidative stress (excessive level of free radicals in cells) is believed to be a reason for the organisms aging and death.
