Nanotribological research of ultrathin organic layers, prepared mainly on ceramic materials, was started at the Department in early 1990s. They were carried out in cooperation with the research team of prof. W. Olejniczak of the Department of Solid State Physics, Faculty of Physics and Applied Informatics, University of Lodz (formerly Faculty of Physics and Chemistry). Since 2001 we have been developing one of our current main focus areas – synthesis and nanotribological research of monolayers and ultrathin organic layers on various solid substrates.

Macrotribological research, carried out by the present Head of the Department since 1972, is continued at the Department until now. One of the main research areas have been tribochemical properties of organic sulphur compounds as protective additives in lubricants, including petrochemical applications.
