On January 15, 2019, Solunov, Hristo Aleksandrov published an article.Electric Literature of 118-55-8 The title of the article was Relations between the sub-molecula and the cooperative scales in the molecular dynamics of the glass-forming liquids. And the article contained the following:
The mols. of the supercooled liquids in the cooperative mol. dynamics are partitioning to specific dynamic units, known as “beads”. The beads have been defined as the smallest units, forming the heat capacity of the supercooled liquids The beads appear as a sub-mol. scale in the dynamics of the glass-forming liquids In the Adam-Gibbs theory the number of mols., rearranging simultaneously, has been defined as the size of the cooperative rearranging region and these regions form the second larger mol. scale in mol. dynamics. Due to a noticeable discrepancy in estimating the number of beads in the mols. by the empirical rules as well as by theor. models the relations between these two scales are not well known. Recently, a new thermodn. method for estimating the number of the beads in the mols. and a rule for the examination of their temperature dependence have been suggested. By these methods 48 low-mol. supercooled liquids are investigated and the relations between these two mol. scales and the structure of the mols. have been found. The estimated number of configuration beads is compared with the number of the structural units (the chem. groups, the ions and the atoms), with the assigned number by the empirical rules and with the ones calculated, based on a Lennar-Jones model of the random first order transition theory. A constant and two kinds of temperature dependence of the number of the beads in the mols. of different liquids have been revealed. A mol. basis, forming the fragility of the supercooled liquids, has been found. From the results obtained, the investigated liquids are classified in several groups following the logical line in the formation of the beads. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Electric Literature of 118-55-8
