Thermobaric synthesis, structure, and properties of Dy x Cu 3V4O12

The perovskite-like compound Dy x Cu3V 4O12 (x = 0.67-0.75) is synthesized under high pressure (P = 4.0-9.0 GPa) and temperature (T = 1000 C). Its crystal structure is determined (Im-3 space group, Z = 2, a = 7.29348(7) Å) by means of powder X-ray diffraction. The basic lengths and bond angles are defined. It is found that the high-pressure phase of Dy x Cu3V 4O12 is characterized by metallic conductivity and paramagnetic properties. © 2013 Allerton Press, Inc

Synthesis and characterization of the new high pressure phases A Cu 3 v 4O 12 (A =Gd, Tb, Er)

New ACu3V4O12 (A=Gd, Tb, Er) phases have been prepared at high pressure and high-temperature conditions (P∼8-9 GPa, T∼1000°C) in a toroid-type high pressure cell. These compounds crystallize in the cubic symmetry with a perovskite-like structure. At ambient pressure, they are paramagnetic and have activation-type conductivity. The effect of high pressure (10-50 GPa) on the electrical properties of the materials was analyzed in the temperature range from 78 to 300 K. Pressure ranges of the transition from activation type to metallic conductivity have been determined. The crystal structure of ACu3V4O12 (A=Gd, Tb, Er) was found to be stable up to 50 GPa. © 2013 Copyright Taylor and Francis Group, LLC

Analysis of Requirements for Inhalation Toxicity Studies of Chemicals

Scientific relevance. Studies of the inhalation administration of chemicals are associated with challenges in designing experiments. The parameters to be selected include the experimental animal species, the inhalation chamber, and the mode of inhalation (dynamic or static).Aim. This study aimed to analyse the practical application of regulatory requirements to non-clinical studies of the inhalation toxicity of chemicals.Discussion. This review compares international and Russian standards for studying the inhalation toxicity of chemicals, including GOST 32542-2013, GOST 32643-2020, GOST 32636-2020, GOST 32383-2013, and GOST 2646-2014. The improvement of the legal and regulatory framework correlates with adopting the Good Laboratory Practice and the risk-based approach to categorising test substances into hazard classes. Hazard classes are determined in rodents without dose extrapolation to humans. The authors present the differences between the main guidelines on inhalation exposure in rodent studies of acute, subacute, subchronic, and chronic toxicity. The article describes current approaches to assessing the inhalation toxicity of chemicals, which allow researchers to replace animal studies with in vitro tests.Conclusions. According to the current regulatory standards, inhalation toxicity is studied in rats/mice, which have anatomical differences from humans. As an alternative to animal studies, researchers are developing and validating in vitro methods, which yet require regulatory review and approval

Influence of the aftereffect of mineral fertilizers on the productivity of a long-term phytocenosis in the conditions of the Privilyui agrolandscape of the middle taiga subzone of Yakutia

The article provides the research of 2011-2019 on studying the long-term influence of the aftereffect of 36-year application of mineral fertilizers on the productivity and nutritional value of long-term meadow phytocenoses. In a stationary experiment with a radical improvement of meadows, the following variants for applying mineral fertilizers were studied from 1974 to 2010: the minimum level was N62P60K11 (control), the average level was N202P175K43, and the maximum level was N318P362K189. In the conditions of the Privilyui agrolandscape of the middle taiga subzone of Yakutia, a long-term aftereffect of fertilizers (from 2011 to 2019) contributed to the preservation of the main dominant in the grass stand - couch grass (Elymus repens (L.) Nevski) up to 27.4-42.1 % and codominant – short-awned barley (Hordeum brevisubulatum (Trin) Link.) up to 14.7-24.3 %. During the aftereffect of fertilizers, the yield of cereal-forb phytocenosis averaged 1.71-2.03 t/ha of hay, which is 2.1-2.5 times higher than the yield of natural meadows. At the same time, hay forage contained up to 8.9-9.1 MJ of exchange energy, up to 0.62-0.65 feed units, and up to 80-90 g of digestible protein, which corresponds to the zootechnical norm
