Deformation of liquid crystal droplets suspended in liquid polymer matrix under the action of external electric field was observed in dependence of ion concentration in such system. Experimental dependence of droplet elongation vs electric field demonstrates nonmonotonous character with...

Electric birefringence in solutions of high molecular weight ribonucleic acid.

Biophysical journal

Golub EI, Nazarenko VG.
PMID: 19210979

The electric birefringence of low ionic strength solutions of high molecular weight ribonucleic acids from various sources was studied. RNA preparations with a high helical content were found to have negative electric birefringence as a result of the segment...

6-[Bis(ethoxycarbonyl)methyl]-6-deoxy-1,2;3,4-di-O-isopropyl-idene-d-galacto-pyran-ose.

Acta crystallographica. Section E, Structure reports online

Doboszewski B, da Silva PR, Nazarenko AY, Nemykin VN.
PMID: 21589509
Acta Crystallogr Sect E Struct Rep Online. 2010 Nov 17;66:o3217-8. doi: 10.1107/S1600536810046921.

The title compound, C(19)H(30)O(9), was prepared by substitution at the C6 position in 1,2;3,4-di-O-isopropyl-idene-6-O-trifluoro-methane-sulfonyl-d-galactose using sodium eth-oxy-malonate in dimethyl-formamide. The conformation is skew-boat (0)S(2), slightly distorted towards boat B(2,5). The inflexible pyran-ose structure makes the title compound a suitable...

Using a magnetic Frederiks transition technique, we measure the temperature and concentration dependences of splay K1, twist K2, and bend K3 elastic constants for the lyotropic chromonic liquid crystal sunset yellow formed through noncovalent reversible aggregation of organic molecules...

Turbulence of Weak Gravitational Waves in the Early Universe.

Physical review letters

Galtier S, Nazarenko SV.
PMID: 29286813
Phys Rev Lett. 2017 Dec 01;119(22):221101. doi: 10.1103/PhysRevLett.119.221101. Epub 2017 Nov 28.

We study the statistical properties of an ensemble of weak gravitational waves interacting nonlinearly in a flat space-time. We show that the resonant three-wave interactions are absent and develop a theory for four-wave interactions in the reduced case of...
