We developed the use of magnetic field for fabrication and driving of artificial cilia made of superparamagnetic colloidal particles. Also presented were the first measurements of the fluid flow created by an array of such cilia. Results of this work were recapitulated in Nature Physics, News and Views, Jan. 2010.

Nanostructured polymer composites can be used for deveices for neutron diffraction optics with wavelength above 1 nm. We analyzed a series of diffraction gratings fabricated from photopolymer composites with SiO2 and ZrO2 nanoparticles. We demonstrated that such a composite holographic grating having the thickness of only 200 micrometers acts as a “50:50 beam splitter” for neutron beam with the wavelength of 2 nm.

Using dynamic light scattering we have shown that the phenomenon of soft elasticity in liquid crystal elastomers is connected with the existence of a soft mode of fluctuations, proving that the theory of M. Warner and E. Terentjev is correct. Our measurement allowed us to determine all the parameters of the theory.

We measured the time dependence of the output power and spectrum in pulsed regime of a fiber laser based on fluoride glass doped with erbium, intended for medical applications, and set up a theoretical model of active state population dynamics and determined the important parameters of the rate equations that well describe the system.

We investigated the aggregation of lipophilic derivatives of guanosine with one, two, or three hydrocarbon tails in Lagmuir films on water. Using the Langmuir-Blodgett procedure we transferred the films on mica and analyzed the structures with atomic force microscopy. We found very different structures for different number of tails, proving that by chemical modfications it is possible to control the self-assembly of guanosine derivatives on surfaces.
