Samara Center for Theoretical Materials Science (SCTMS)

• New geometrical-topological methods for the analysis of the crystal structure of coordination polymers, metal-organic frameworks and molecular crystals have been developed, the corresponding software and a prototype of an expert system have been created to predict the structure of these polymers and crystals.
• A combined topological-quantum-mechanical method for predicting the cleavage of organic crystals has been developed, which makes it possible to use them as substrates for molecular beam epitaxy. The topological part of the method is implemented in the ToposPro software package.
• Algorithms have been developed for the combined application of fast geometric-topological methods and exact methods of mathematical modeling (methods of density functional and molecular dynamics) to predict the structure and physical properties of new materials.
• A hybrid topological-quantum-mechanical approach to the analysis of the structure and thermodynamic properties of intermetallic compounds has been developed, which consists in searching for possible topological configurations of the crystal structure of the intermetallic compound and subsequent assessment of their stability by quantum-mechanical methods.

Implemented achievements:

Practical application of software, electronic knowledge bases for research, classification and prediction of geometric, topological and physical properties of crystalline substances and materials of various nature. He created products, implemented in the ToposPro software package, are used to describe and predict new crystalline substances and materials in research laboratories in 65 countries of the world.

A computer express method for predicting ionic conductivity in crystalline bodies has been developed, the method is implemented in the ToposPro software package.

The method of searching for structural units for modeling crystal growth in the CrystalGrower software package, previously developed in collaboration with colleagues from the University of Manchester (UK), has been improved. Developed a joint software package CrystalGrower + ToposPro (https://crystalgrower.org/).

A local version of the ExMOF information and analytical system has been developed, included in the ToposPro software package, available on the website https://topospro.com.

A free online service for determining the topology of the crystal structure by CIF file has been developed (topcryst.com).

Electronic knowledge bases have been created: Database of Structural Building Units, Samara Carbon Allotropes Database, Topological Types of Crystal Structures, Topology Online Research Information System, Topological Types Collections, Topological Types of Ligands, Database of Metal-Organic and Organic Building Blocks, Coordination clusters.
