The structure of MQ copolymers of the general chemical formula [(CH3)3SiO0.5]m [SiO2]n was characterized by means of solid-state magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. The MQ copolymers are highly branched polycyclic compounds (densely cross-linked nanosized networks). MQ copolymers were prepared by hydrolytic(More)
The water self-diffusion behavior in yeast cell water suspension was investigated by pulsed field gradient NMR techniques. Three types of water were detected, which differ according to the self-diffusion coefficients: bulk water, extracellular and intracellular water. Intracellular and extracellular water self-diffusion was restricted; the sizes of(More)
This paper presents one definition of the Russian Federation’s national security, identifies the role of scientific and technological progress as the basis for this security and shows the development of its innovation. The study treats the concept of expertology as a line of scientific and analytical activities; examines the techniques for the state expert(More)
Frozen-dried preparations were studied for the impact of moisture content of the nuclear magnetic resonance parameter that was a ratio of the amplitudes of a slow component and a rapid one of a free induction signal from the protons of samples. It was found that there was a linear correlation between this parameter and the moisture content of biological(More)
The electrosurface properties of track membranes made from poly(ethylene terephtalate) were determined by streaming potential (SP) and electron spin resonance (ESR) methods. The membrane pore diameters were in range from 20 to 200 nm. The pore electrical charge surface density values calculated with data obtained with methods mentioned differed(More)
