Research area
The laboratory is focused on studying dissipative structures known as “Droplet clusters”. This new phenomenon was discovered by A.A. Fedorets in 2003. A droplet cluster is a two-dimensional aerosol with a number of unique characteristics. It is a monolayer of spherical microdroplets levitating in a gas medium over a locally-heated surface of water or other liquids. Strict spatial localization of the cluster provides qualitatively new opportunities for the development of precision methods for studying physical and chemical processes under experimental conditions that closely resemble the atmosphere. Technologies developed in this laboratory will make it possible to deepen our understanding of the chemical evolution of atmospheric pollution and the resulting global climate change. These technologies will also increase the efficiency of sprayed chemical and biological plant protection products. One of the primary objectives of the laboratory is to develop new methods for the abiogenic synthesis of complex organic molecules in a microdroplet reactor. Another goal of our lab is to learn more about the ability of microorganisms to live in atmospheric aerosols.
