W3 - Faculty of ChemistryK-31, Department of Molecular PhysicsForming pellets or thin layers

Forming pellets by pressing materials intended for analysis at ambient temperature, e.g., ceramic materials, drugs/temperature-sensitive materials. The resulting material is useful for spectroscopic studies, including dielectric, UV-Vis, infrared spectroscopy (in the form of a KBr/material mixture), and others.

Forming thin layers by:
- pressing at elevated temperatures using a hydraulic press (the advantage of this method is that it avoids the use of a solvent);
- repeated soaking using a dip-coater, including: thin organic layers – deposited from polymer solutions; precursors to ceramic layers;
- using zone pouring to obtain ordered organic layers (the method involves the preparation of polymer solutions);
- pouring onto a spinning substrate – preparation of thin and very thin polymer layers (the method involves the preparation of polymer solutions).

W3 - Faculty of ChemistryK-31, Department of Molecular PhysicsSimulations of dense liquid systems with full dynamics of the investigated process

Simulations of polymer chains in the form of mixtures and dilute systems for simple polymers, copolymers, polymer brushes and stars, as well as gels and microemulsions with precisely defined topology, simulations of atom transfer radical polymerization (ATRP), modeling of chemical reactions with assumed substrate mobility in environments with complex geometry, studies of diffusion in liquids in bulk and confined spaces, investigation of phase separation phenomena in simple and complex systems and problems related to percolation and aggregation, statistical studies of single polymer chains across a full temperature range, and analysis of chain-surface interactions.

The research includes determining structure factors, diffusion constants, concentration profiles and reaction fronts, parameter variations as a function of conversion for chemical reactions, relaxation times and percolation thresholds, and conducting scaling analysis for finite systems and dynamic scaling (if applicable).
