Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Relationship of associated clusters degree with metal ionization according to the cluster-associate modelThis article deals with a cluster-associate model of kinematic viscosity of liquid metals.This model was derived from the concept of chaotized particles.According to the proposed model, the authors calculated average values clusters association degree contained in liquid metal.28 metals of the secondsixth periods of D.I. Mendeleyev element table were studied for calculation.The authors compare the first potential of metal ionization with the obtained values of clusters association degree.This comparison showed a regular change in clusters association degree closely connected with the change in the first ionization potential.In combination with the Fraenkel equation, an approximate equation was obtained to calculate activation energy.The obtained equation for the cluster-associate pattern of viscosity temperature dependence is used in calculating the activation energy of viscous melt flow for twenty-eight metals.The obtained results on activation energy were compared to experimental data.This comparison showed that the activation energy data obtained from the proposed model is described better by the approximating dependence.Tables and figures are given in the work for visual confirmation of the obtained results.Thus, in the process of comparing the first potential of metal ionization for all periods of D.I. Mendeleyev element system with clusters association degree, their regular connection was revealed.This connection makes it possible to assert the functional aspect of the cluster-associate pattern.
