THE LONGEVITY OF OAK TREES AND OAK FOREST
Forestry Engineering Journal, 2017 Practically nothing from scientific research is dedicated to definition of the maximum age of individual trees of oak and oak stands in conditions of the Central forest-steppe , although it is crucial to know these parameters for selecting genetic reserves, design of protected areas and natural monuments.

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring
Advanced Functional Materials, EarlyView.This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.
