The Laboratory of Physico-Chemistry of Modified Surfaces was established at the Frumkin Institute of Physics and Technology of the Russian Academy of Sciences in 1989 on the initiative of Academician Boris Vladimirovich Deryagin, an outstanding scientist who laid the foundations of modern science on colloids and surfaces. B.V.Deryagin moved to a new laboratory with his research group. In addition, Rabinovich's group joined the laboratory. Since 1993, the laboratory has been headed by Olga I. Vinogradova. Currently, the main areas of work of our laboratory are related to the application of theoretical and mathematical methods to problems arising at the interface of soft condensed matter, fluid and solid mechanics, as well as nanoscience. Current research topics include micro- and nanofluidics, membranes, microgels and microcapsules, and active colloids. Our applications lie in the fields of materials science, electrochemical systems, wetting, adhesion and friction, drug delivery, and more.

Research directions

Nanofluidics

+
Nanofluidics
Nanofluidics is a world of infinitesimals in hydrodynamics, the boundary of continuum hydrodynamics. The transport of liquid and ions in nanochannels differs significantly from what happens on the micro and macroscale. The surface of the channel walls and the concentration of the electrolyte play a huge role, and currents caused by an electric field or concentration gradients are effective. As a result, ultrafast currents and gigantic electrical conductivity can be created in nanochannels and nanotubes. In addition, nanofluidics is an area in which the path from basic science to breakthrough innovations is short, especially in the field of desalination, water purification or osmotic energy.

Active colloidal particles

+
Active colloidal particles
Self-moving particles, or micro-particles, have opened up a new field of research from both a fundamental and a practical point of view. Our research is focused on the theoretical description of the self-movement of catalytic micro-traps that release ions unevenly.

Microfluidics

+
Microfluidics
Microfluidics problems are excellent examples of the need for an interdisciplinary and multiscale approach that requires a combination of various theoretical methods (including approximate, asymptotic, and scaling). Our topics of interest include the quantitative description of flows near superhydrophobic surfaces and permeable porous coatings, modeling of electrokinetic and other interphase transport phenomena, and the development of new principles of separation and passive mixing in microchannels.

Electrostatics in soft matter

+
Electrostatics in soft matter
In electrolyte solutions, the functional, structural, and dynamic properties of charged objects, as well as their interactions, are largely determined by established electrostatic equilibria. They are responsible for the stabilization of colloidal suspensions, the size and rigidity of microgels and microcapsules, the interaction of particles with semipermeable membranes, etc. The range of our research in this area is quite wide and includes the theory of a double electric layer, the electrostatics of capillarity and wetting phenomena, diffuse layers near catalytic particles, etc.

Electrophoresis

+
Electrophoresis
Electrophoresis is the phenomenon of migration of charged particles under the action of an applied electric field. Electrophoretic experiments have played a huge role in the development of the science of colloids. Today, electrophoresis finds numerous applications in many fields such as microfluidics, DNA sequencing, drug delivery, analytical chemistry, and medicine. Our research in this field extends from the electrophoresis of small ions, which determines the electrical conductivity of solutions of inorganic salts, to the electrophoresis of large (passive) catalytic particles.
