Mineral solid solutions structure and properties supercimputer modeling
Eremin Nicolai
Moscow State Uiversity
DRIVER: Implement a set of atomistic, molecular dynamics and quantum chemical methods for simulation of crystal structures, defects, and radiation resistance of minerals and their solid solutions in some oxide and silicate systems
STRATEGY: The authors have a number of original designs that allow, first, in the framework of representative super cell receive properties of disordered solid solution and their comprehensive review of its properties, and secondly, can physically reasonable to consider the charge transfer energy, allowing the use of strict energy basis for modeling with all values of the effective atomic charges.
OBJECTIVE: 1) The estimation of radiation resistance of mineral-like matrices; 2) Predicting of the physical properties of inorganic compounds of variable composition
IMPACT: The establishment of new technologically advanced materials with variable composition
USAGE: environmental management, ecology, earth sciences,
AREA: Geology, Structure and Dynamics of Atomic-Molecular Systems
