Steric Effects in the Deposition Mode and Drug-Delivering Efficiency of Nanocapsule-Based Multilayer Films. [PDF]
ACS Omega, 2022 Using surface-initiated atom transfer radical polymerization (ATRP), block polymers with a series of quaternization degrees were coated on the surface of silica nanocapsules (SNCs) by the “grafting-from” technique.

Interplay of Electronic and Steric Effects to Yield Low-Temperature CO Oxidation at Metal Single Sites in Defect-Engineered HKUST-1. [PDF]
Angew Chem Int Ed Engl, 2020 In contrast to catalytically active metal single atoms deposited on oxide nanoparticles, the crystalline nature of metal‐organic frameworks (MOFs) allows for a thorough characterization of reaction mechanisms. Using defect‐free HKUST‐1 MOF thin films, we

Steric effects in cyclization reactions [PDF]
Australian Journal of Chemistry, 1976 Calculations of geometric probability factors indicate that steric effects are important in determining whether the cyclization of β-substituted diallylmethylammonium ions results in five- or six-memberedrings. Evidence is obtained of the direction of intramolecular attack.

Electrostatic and steric effects underlie acetylation-induced changes in ubiquitin structure and function [PDF]
Nature Communications, 2022 Ubiquitin is not only a posttranslational modifier but itself is subject to modifications, such as acetylation. Characterization of distinct acetylated ubiquitin variants reveals that each acetylation site has a particular impact on ubiquitin structure ...
