Direct Spectroscopic Identification of BN-Arynes and Subtle Steric Effects on Nitrogen Fixation [PDF]

open access: yes, 2023
1,2-Azaborinines are the BN analogues of arynes through exchange of the formal CC triple bond by an isoelectronic BN bond. The BN-arynes are an underexplored class of reactive intermediates.

Steric, Electronic and Conformational Synergistic Effects in the Au(I)-catalyzed alpha-C-H Bond Functionalization of Tertiary Amines [PDF]

open access: yes, 2022
Direct C-H bond functionalization is a useful strategy for the straightforward formation of C-C and C-Heteroatom bonds. In the present work, a unique approach for the challenging electrophilic Au-catalyzed alpha-C-H bond functionalization of tertiary ...

On the asymptotic limit of steady state Poisson--Nernst--Planck equations with steric effects [PDF]

open access: yes, 2022
When ions are crowded, the effect of steric repulsion between ions becomes significant and the conventional Poisson--Boltzmann (PB) equation (without steric effect) should be modified.

Hypervariability of accessible and inaccessible conformational space of proteins

open access: yesCurrent Research in Structural Biology, 2021
Proteins undergo motions in a range of amplitudes, from domain motions to backbone rotations, leading to changes in (φ,ψ) torsion angles and small-scale bond vibrations and angle bending.

El Niño, La Niña, and the global sea level budget [PDF]

open access: yesOcean Science, 2016
Previous studies show that nonseasonal variations in global-mean sea level (GMSL) are significantly correlated with El Niño–Southern Oscillation (ENSO).

Steric effects of ions in the charge-related wetting phenomena [PDF]

open access: yes, 2018
Steric effects of ions on the charge-related wetting phenomena are studied. Along with a general treatment, three specific problems in two-dimensional system are considered: a droplet on an electrode, a droplet on a charged surface, and an electrowetting

Substituent effects on nonadiabatic excited state dynamics: Inertial, steric, and electronic effects in methylated butadienes

open access: yes, 2020
The photochemical dynamics of double-bond-containing hydrocarbons is exemplified by the smallest alkenes, ethylene and butadiene. Chemical substituents can alter both decay timescales and photoproducts through a combination of inertial effects due to ...
