The Laboratory was established within the section of Chemical and Biological Physics and conducts research in collaboration with the Voevodsky Institute of Chemical Kinetics and Combustion of the SB RAS on the following themes:
- structure and dynamics of biological molecules;
- creation of new functional molecular materials, promising for electronics, and the study of their properties;
- study of the properties of new molecular materials for the energy sector;
- optical properties of nanoparticles, including amplification of the radiation of molecules.
The laboratory reached the following results:
- It was shown that the lifetime of optical phonons in Diamond is determined by an anharmonic interaction, involving both three-particle interaction (relaxation via the Klemens channel), and four-particle interaction. Thereby we obtained a final answer to the question which was offered various solutions for the last 60 years.
- We developed a method to determine the mass of DNA in blood cells using Raman Raman spectroscopy (and without using dyes).
- We obtained results in the development of the discrete dipole approximation - a universal method for modeling the linear interaction of electromagnetic waves with small particles of arbitrary shape and structure.
- We developed an effective algorithm which is applicable to a wide range of particle size - from nanoparticles to much larger wavelength. The method has been optimized for highly elongated and flattened nanoparticles and to simulate the scattering of femtosecond laser pulses.
- We detected long-range (up to 10 nm) intermolecular interactions in biological membranes and long-range reciprocal regulation of molecules.
- We set a 3D magnetic motive with ferromagnetic and antiferromagnetic exchange interactions in order to synthetize Heterospin Radical-Ion salt Bis(mesitylen) molybdenum and Radical-Anion Salt[1,2,5]Thiadiazolo[1,2,5]thiadiazolidyl by quantum chemical calculations.
- With the help of high-level ab initio calculations (SOC-CASSCF/NEVPT2) we established the electronic structure and explained the properties of Rhenium Complex with Noninnocent Dioxolene Ligand.
- For the elaboration of P3HT/PCBM composites for organic photovoltaic we determined the average distance between the radicals P3HT + and PCBM-, forming a charge-transfer state at 2-3 nm.
