Thermodynamic model of hardness: Particular case of boron-rich solids

A number of successful theoretical models of hardness have been developed recently. A thermodynamic model of hardness, which supposes the intrinsic character of correlation between hardness and thermodynamic properties of solids, allows one to predict hardness of known or even hypothetical solids from the data on Gibbs energy of atomization of the elements, which implicitly determine the energy density per chemical bonding. The only structural data needed is the coordination number of the atoms in a lattice. Using this approach, the hardness of known and hypothetical polymorphs of pure boron and a number of boron-rich solids has been calculated. The thermodynamic interpretation of the bonding energy allows one to predict the hardness as a function of thermodynamic parameters. In particular, the excellent agreement between experimental and calculated values has been observed not only for the room- temperature values of the Vickers hardness of stoichiometric compounds, but also for its temperature and concentration dependencies

Digitalization of the Russian Economy as a National Goal

The gist of this article boils down to the legal conditions for the formation of a unified system of digitalization of the economy based on the improvement of normative regulation of the digital environment are considered; creation of information infrastructure of the economy; providing the digital economy with competent personnel; ensuring information security. The authors conclude that the state concept of "digital transformation" has not yet been implemented, but the first steps in this direction have been taken. Achieving the national goal of digitalizing the economy will entail the creation of a new legal framework for relations between citizens, business and the state, which is necessary (and even inevitable) due to the development of digital technologies

Digitalization of State Corporations and Companies with State Participation

The article analyzes the legal acts regulating public relations in the field of digital transformation of state corporations in order to determine the priority organizational, economic and managerial directions of their development. At the same time, the research carried out is also relevant for organizations of other organizational and legal forms
