16.12.2019 - FLNR Laureates of JINR Prize 2018-2019 for young scientists and specialists.



09.12.2019 - A new preprint "Extrapolational Estimations of Physical-Chemical Properties of Nihonium, Tennessine and Oganesson" P6-2019-48 was published by the JINR Publishing Department.
The author of the work is Norseev Yu. V.

Abstract:

The method of comparing calculations is a correlational relation, connecting some properties with other ones in every group of analogical elements. Linear relation between logarithms of retention indexes of organic haloderivatives with one and the same substitutes and their different physical-chemical properties allowed determining extrapolationally boiling and melting point temperatures, heats of vaporization, refraction, carbon-astatine binding energy and dipole moments. Some properties of elemental astatine were determined. The method of comparing calculations can be used for estimating some physical-chemical properties of nihonium, tennessine and oganesson. It is shown in the figures that linear dependence of some properties on other ones is observed in groups of these elements. Averaged values of their physical-chemical properties obtained because of building more than three relations are given in the tables for these elements.
