Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The results of studying the structure of porous condensates of Fe–NaCl composition, chemical, phase compositions and size of nanoparticles obtained by physical synthesis from the vapor phase using electron-beam physical vapor deposition method, are considered. With a rapid recovery from vacuum, iron nanoparticles are oxidized in the air to magnetite. In the initial state, they have significant sorption capacity with respect to oxygen and moisture. Physically adsorbed oxygen participates in the oxidation of Fe3O4 to Fe2O3. An increase in condensation temperature is accompanied by the increase in size of nanoparticles, as a result of which the total surface area of nanoparticles is significantly reduced, and, consequently, their sorption capacity is decreased. Even without stabilization, such nanoparticles studied as ex tempore prepared aqueous dispersion have characteristic anti-anemic effect in the laboratory animals that can be used in medicine. Ref. 41, Tabl. 2, Fig. 5.
Keywords: EB PVD; iron oxide nanoparticles; sorption; phase composition; colloid systems; anti-anemic effect
