WebApr 7, 2024 · The H-bond has a large orbital interaction energy, which is found to contribute significantly to the adhesive strength at the ER/GO interface. The overall interaction at the ER/graphene is much weaker due to antibonding type interactions just below the Fermi level. WebIn chemistry, π-effects or π-interactions are a type of non-covalent interaction that involves π systems. Just like in an electrostatic interaction where a region of negative charge interacts with a positive charge, the electron-rich π system can interact with a metal (cationic or neutral), an anion, another molecule and even another π ...
WebNov 19, 2012 · Amide carbonyl groups in proteins can engage in C═O···C═O and C–X···C═O interactions, where X is a halogen. The putative involvement of four poles suggests that these interactions are primarily dipolar.
