The chapter "Origin of Puckering (Buckling) of Planar Heterocycles and Methods of Its Suppression," authored by N.N. Gorinchoy and I.B. Bersuker, is a comprehensive and insightful contribution to the field of physical chemistry, with a strong emphasis on quantum calculations and computational chemistry. The two authors are well-known in the scientific community for their contributions to the understanding of the structure and reactivity of various classes of compounds, based on the consequences of the Jahn-Teller effect. Published as part of the monograph Heterocycles: Synthesis, Reactions and Applications by Nova Science Publishers, Inc. (2020), this chapter spans 60 pages and is structured into an Introduction, three main sections with eight subsections, Conclusions, and a list of 50 relevant references. The authors delve into the structural deviations of heterocyclic compounds, particularly focusing on the phenomenon of puckering or buckling, which significantly influences their properties. The chapter not only elucidates the mechanisms behind these distortions but also provides practical methods for their suppression and the restoration of planar configurations.

 

 

Graphycal Abstract: The impact of doping graphene with metals like Cu, Al, and Mn on its adsorption strength for arsenic (As) was computationally explored for industrial wastewater treatment. The results show that doped graphene outperforms undoped graphene, suggesting that doping can enhance the adsorptive properties of graphene for As removal.
