Steric Effects in Electrolytes: A Modified Poisson-Boltzmann Equation [PDF]

, 1998
The adsorption of large ions from solution to a charged surface is investigated theoretically. A generalized Poisson--Boltzmann equation, which takes into account the finite size of the ions is presented.

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 ...

Insights on tert-butyl alkylation effects on fluorobenzene

Scientific African, 2021
Directing effects of substituents on the benzene ring, ortho and para directors by electron donating groups and meta directors using electron withdrawing groups have been studied and reported widely. In particular and for many years, the directing effect
