Interests
Research interests focus on the change of the physical and chemical properties of nanomaterials in size-dependent first order phase transformations. I investigate size-dependent energy-related issues of nanosized films and nanoparticles concerning their stability and performance, isobaric temperature-composition phase diagrams of multicomponent nanosystems, size-induced kinetics of colloidal solutions, nanosized phase growth kinetics and а binary diffusion couple, isolated nanoparticles, metastable alloys specifically targeting the influence of the characteristic size on the phase transformation, structure and diffusion activity of various materials during isothermal annealing.
Of special interest is highlighting the role of size effect in such phenomena as:
- melting and crystallization of continuous metal and alloy films (including multilayers),
- phase separation / decomposition in solutions and metallic systems,
- surface-induced size effects in nanomaterials;
- lattice parameter variation in metallic nanosystems,
- width of the thermal hysteresis cycle in a nanopowder during the first order phase transformation,
- microstructure and properties of metallic systems,
- property changes induced by changes of atom-atom interactions,
- diffusion and reactive diffusion in multicomponent systems.Projects
