Unexpected nanoscale CeO structural transformations induced by ecologically relevant phosphate species.

In the present study, the dissolution and microstructural transformation of CeO nanoparticles (NPs) in a phosphate-containing milieu were investigated. The dissolution behaviour of 2 nm and 5 nm CeO NPs in phosphate buffer solutions was found to differ markedly from that observed in 0.01 M NaClO.

Physical and mechanical properties of hard seed coat on the example of Gleditsia triacanthos L.

The microhardness of individual morphological structures of the hard coat of the seed of Gleditsia triacanthos L. was measured. Measurements were made on the transverse and frontal planes.

The influence of biological products and growth regulators on the yield and quality indicators of pea seeds of various varieties.

Peas are an important agricultural crop of great importance in human and animal nutrition. Peas, being a legume crop, help replenish nitrogen reserves in the soil. In field studies of the Federal State Budgetary Scientific Institution of the Federal Scientific Center of Legumes and Goat Crops (Oryol region), the influence of various growth regulators and biological products on the yield and quality indicators of pea seeds of the Nord and Multik varieties was studied.

Morphological and physiological properties of lupine nodule bacteria (Bradyrhizobium lupini) when grown on a typical urban soil.

In the conducted studies, the moorphological and physiological properties of nodule bacteria of lupine were studied. Lupine plants were grown under the conditions of a microfield experiment on a typical medium loamy urban soil. In the study, a pure culture of Bradyrhizobium lupini was isolated.

Protecting spring wheat plants using selenium and pesticides.

The research was carried out in order to find ways to optimize the system of protection of spring wheat crops. In the conducted studies, the effect of combinations of sodium selenite and various pesticides, differing in the specifics of action and biological activity, on the yield and quality of spring wheat of the Yubileinaya 80 variety was studied. Currently, there is a need to achieve a sufficient effect of the action of chemical plant protection products and to obtain a minimum impact on human health and the environment.
