The effect of ferroelectric poling on the adsorption characteristics of water at lithium niobate surfaces is investigated by ab initio calculations. Thereby we model the adsorption of H2O monomers, small water clusters, and water thin films on the LiNbO3(0001) surface. The adsorption configuration and energy are determined as a function of the surface coverage on both the positive and negative ...

Background: Plum diploid is a new species for the conditions of Volgograd region Russia, not previously grown. There are large number varieties and rootstocks that need to be studied in relation growing conditions. Methods: The research was carried out 2020-2022. Drought resistance heat were determined by laboratory method. To account these indicators, water content leaf, deficit water-holding ...

The halophytic vegetation of the Lopatinsky District in Penza Region was studied on example five solonets (Litvinovsky, Lipovsky, Staro-Vershautsky, Olginsky and Belogorsky). Halophytic meadows (44,0%) slightly prevail over steppes (36,0%) all these salt lakes. 550 species vascular plants have been identified Region, 29 rare identified, 2 (Iris aphylla, Stipa pennata) are protected at federal l...
