Research
topics:
State
of matter at interfaces and in thin liquid films
- Thin liquid
films (foam, emulsion, wetting) - formation and stability.
- Thin liquid
films as a model of colloid stability.
- Surface
forces in thin liquid films - short-range and long-range interactions.
Theoretical and experimental investigations of DLVO and non-DLVO
forces.
- Amphiphilic
bilayers of phospholipids and surfactants. Phase transitions
in phospholipid bilayers.
- (Bio)polymers
at solution/air interfaces - foam films of polymers:
polymer/surfactant and phospholipid/surfactant interactions.
- New methods
for characterization of electric surface parameters of gas liquid
interface.
- Self-assembly
in thin liquid films.
- Applications
in biology and medicine - lung surfactant diagnostic methods
(lung maturity test, therapeutic lung surfactant, etc.), biomembranes,
biosurfactants and biomaterials.
- Applications
in oil production, water pollution and treatment, food production,
physicochemical characteristics of natural and synthetic surfactants
and determination of their efficiency.
Electro-optics
of Colloids
- Surface
electric properties of suspended particles.
- Colloid
stability and processes of particle aggregation.
- Colloidal
phase transitions and viscoelastic properties of disperse systems.
- Adsorption
of ions, surfactants and polymers on colloid particles.
- Particle
size determination.
- Applications
in biology, medicine, ecology and (bio)technology.
