Оптимизация процесса получения биологически активного диацетата бетулина из исходной и активированной бересты березы
The effect of the conditions of the acetylation process of raw and activated birch bark on the yield and composition of the products is investigated. The structure of biologically active betulin diacetate (BDA) is confirmed ...
Microwave-assisted synthesis and antitumor activity of the supramolecular complexes of betulin diacetate with arabinogalactan
In this work, a water-soluble supramolecular complex was synthesized in an aqueous suspension of betulin diacetate (BDA) and arabinogalactan (AG) upon microwave heating. Microwave heating allows reducing the time required ...
Influence of the Doppler effect on radiative transfer in a spherical plasma under macroscopic motion of substance
The non-LTE radiative transfer in spherical plasma containing resonantly absorbing of light ions has been studied numerically under conditions of macroscopic motion of substance. Two types of macroscopic motion were ...
On the origin of membrane potential in membranes with polarizable nanopores
We report a new mechanism for the generation of membrane potential in polarizable nanoporous membranes separating electrolytes with different concentrations. The electric field generated by diffusion of ions with different ...
