Steric effects in the dynamics of electrolytes at large applied voltages: II. Modified Poisson-Nernst-Planck equations [PDF]

open access: yesarXiv, 2006
In situations involving large potentials or surface charges, the Poisson Boltzman(PB) equation has shortcomings because it neglects ion-ion interactions and steric effects. This has been widely recognized by the electrochemistry community, leading to the development of various alternative models resulting in different sets "modified PB equations ...

The steric effect of a trifluoromethyl group.

open access: yesChemical and Pharmaceutical Bulletin, 1991
In the study of ene reaction of trifluoromethyl ketones, a trifluoromethyl group was found to behave as a much larger substituent than commonly believed. Similar results were obtained in the dehydration of trifluoromethyl homoallyl alcohols.

Steric hindrance induced low exciton binding energy enables low‐driving‐force organic solar cells

open access: yesAggregate
Exciton binding energy (Eb) has been regarded as a critical parameter in charge separation during photovoltaic conversion. Minimizing the Eb of the photovoltaic materials can facilitate the exciton dissociation in low‐driving force organic solar cells ...
