Sensitivity Measurement for Bio-TFET Considering Repulsive Steric Effects With Better Accuracy

IEEE transactions on nanotechnology, 2022
Sensitivity analysis of label free Bio-TFET considering repulsive steric effects (RSEs) has been addressed in the paper. Doping-less underlap dielectric modulating tunnel field effect transistor (DU-DM-TFET) is assumed like a reference structure ...

Dispersion and Steric Effects on Enantio-/Diastereoselectivities in Synergistic Dual Transition-Metal Catalysis.

Journal of the American Chemical Society, 2022
Comprehensive computational studies were carried out to explore the mechanisms of enantioselective Cu/Pd and stereodivergent Cu/Ir dual-catalytic syntheses of α,α-disubstituted α-amino acids (α-AAs).

Interplay of Steric Effects and Aromaticity Reversals to Expand the Structural/Electronic Responses of Dihydrophenazines.

Journal of the American Chemical Society, 2022
To gain insights into the coupling of conformational and electronic variables, we exploited steric hindrance to modulate a polycyclic skeleton with a bent conformation in the S0 state and a twisted conformation in the S1 state under the guidance of ...

Controlling Oxygen Reduction Selectivity through Steric Effects: Electrocatalytic Two-Electron and Four-Electron Oxygen Reduction with Cobalt Porphyrin Atropisomers.

Angewandte Chemie, 2021
Achieving a  s elective 2e -  or 4e -  oxygen reduction reaction (ORR) is critical but challenging. Herein, we report controlling ORR selectivity of Co porphyrins by tuning only steric effects.

Steric-Effects-Directed B-H Bond Activation of para-Carboranes.

Journal of the American Chemical Society, 2021
The controllable B-H bond activation of carboranes has long been a compelling challenge. However, as the symmetry of para-carborane places the same charge on all of its ten boron atoms, controlling the regiochemistry of B-H bond activation in these ...
