Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Geophysical Monograph Series, Page 417-434., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Assessment of antibacterial activity of vinyltriphenylphosphonium hexabromoplatinate
Журнал микробиологии, эпидемиологии и иммунобиологии, 2022 Introduction. One of the biological effects of platinum compounds is antibacterial action against Gram-positive and Gram-negative bacteria. Thus, some platinum compounds may inhibit the synthesis of DNA, RNA and proteins in Escherichia coli cells.Aim ...

Transient deep-water oxygenation recorded by rare Mesoproterozoic phosphorites, South Urals
Precambrian Research, 2021 The Mesoproterozoic deep ocean is thought to have been largely anoxic, dominated by ferruginous conditions. Phosphate was scavenged from the water column by iron oxyhydroxides, and dissolved nitrate was rapidly reduced along the redoxcline.
