Composition, Seasonal Dynamics and Metabolic Potential of the Rhizosphere Microbiome Associated with Wild White Poplar.

The white poplar () is a dioecious woody plant with significant potential for the phytoremediation of soils. To realize this potential, it is necessary to utilize growth-promoting microorganisms. One potential source of such beneficial microorganisms is the rhizosphere community of wild-growing trees.

Synthesis and Structure of Vanadium-Lead Coatings for Outer Space Structures.

This study aimed to develop a technology for synthesizing non-degrading porous coatings that remain stable under the conditions of outer space. Using the magnetron sputtering method, we obtained vanadium-lead system coatings over a wide range of mutual concentrations from 6 to 44.9 at.

New Structural State of Tungsten in Obtaining Porous Tungsten Coatings.

For the first time, porous tungsten coatings were obtained by vacuum annealing of coatings consisting of both lead solution in β-W and a mixture of Pb solution in β-W and pure lead. Electron microscopic studies of the obtained coatings before and after vacuum annealing at 800 °C for 1 h and 6 h were carried out. The formation of a new phase of tungsten with an octa-lattice and parameter a = 0.

Thermodynamics of Formation and Liquid-Vapor Phase Transitions of Antimony Alloys with Selenium and Sulfur.

The authors conducted liquid solution studies of antimony with selenium and sulfur in order to provide information on the thermodynamic functions of the formation of these alloys. The studies are based on the vapor pressure values of the components, comprising the double partial systems of antimony with antimony chalcogenides (SbSe and SbS) and antimony chalcogenides with chalcogens (Se and S). We calculated the thermodynamic functions of mixing (graphical dependencies) and evaporation (tabular data) based on the partial vapor pressure values of components, which are represented by temperature-concentration dependencies.

Culturable Bacterial Endophytes of Wild White Poplar ( L.) Roots: A First Insight into Their Plant Growth-Stimulating and Bioaugmentation Potential.

The white poplar ( L.) has good potential for a green economy and phytoremediation. Bioaugmentation using endophytic bacteria can be considered as a safe strategy to increase poplar productivity and its resistance to toxic urban conditions.
