Research

Our group pursues the development of chemical bonding models for sub-nanoparticles, 1D- 2D- and 3D- novel materials that could have a significant impact on rational design of nanocatalysts, nanomaterials with tailored properties, nano-scale electronic devices, etc. We have collaborations with Prof. Lai-Sheng Wang (Brown University, USA), Prof. Kit H. Bowen (Johns Hopkins University, USA), Professor Kirill Kovnir (University of California Davis, USA), Professor Svilen Bobev (University of Delaware, USA), Professor Gernot Frenking (Philipps-Universitat Marburg, Germany), Professor Thomas Heine (Jacobs University Bremen, Germany), Professor Jesus M. Ugalde (Euskal Herriko Unibertsitatea, Spain), Professor Gabriel Merino (Centro de Investigacion de Estudios Avanzados, Mexico), Professor Artem R. Oganov (Skolkovo Institute of Science and Technology, Russia), Professor Jun Li (Tsinghua University, China), Professor Zhong-Ming Sun (Changchun Institute of Applied Chemistry, China) and many other groups around the world, which are very successful due to the fact that we strengthen our projects by combining theoretical and experimental results.

Working on this idea we made interesting discoveries:

1. We developed a new theoretical method called “Adaptive Natural Density Partitioning” designed for deciphering multicenter bonding in molecules and clusters.

Developing paradigms of chemical bonding: adaptive natural density partitioning

This method is now used in more than 50 research groups around the world.

2. We explained chemical bonding in the novel [Pd4(μ4-C9H9)(μ4-C8H8)]+ sandwich type complex using δ-aromaticity.

3. In a joint experimental (Professor Lai-Sheng Wang) and theoretical study we found new clusters Ta©B10 and Nb©B10 with the highest coordination number in two-dimensional envirinment.

This work is highlited in Chemical & Engineering News, and Angew. Chem. Int. Ed and other media outlets.

4. We proposed a new concept for predicting new molecules and materials based on the “electronic transmutation” (an atom acquiring an extra electron starts to behave as the neighboring atom in the Periodic Table, e.g. B- is forming compounds similar to carbon).

5. We computationally predicted in collaboration with Professor Chris J. Pickard inorganic double-helix structure for Li-P compounds.

6. In collaboration with professor J. R. Schmidt group we developed “Solid State Adaptive Natural Density Partitioning” method for analyzing delocalized chemical bonding in 1D-, 2D-, and 3D- compounds.
