Does the Intra‐Atomic Deformation Energy of Interacting Quantum Atoms Represent Steric Energy?
ChemistryOpen, 2019 We show that the mutual, through‐space compression of atomic volume experienced by approaching topological atoms causes an exponential increase in the intra‐atomic energy of those atoms, regardless of approach orientation. This insight was obtained using

Density Functional Studies on Secondary Amides: Role of Steric Factors in Cis/Trans Isomerization
Molecules, 2018 Cis/trans isomerization of amide bonds is a key step in a wide range of biological and synthetic processes. Occurring through C-N amide bond rotation, it also coincides with the activation of amides in enzymatic hydrolysis.

Bi-steric mTORC1 inhibitors induce apoptotic cell death in tumor models with hyperactivated mTORC1
The Journal of Clinical Investigation, 2023 The PI3K/AKT/mTOR pathway is commonly dysregulated in cancer. Rapalogs exhibit modest clinical benefit, likely owing to their lack of effects on 4EBP1. We hypothesized that bi-steric mTORC1-selective inhibitors would have greater potential for clinical ...

Steric-Hindrance-Controlled Laser Switch Based on Pure Metal–Organic Framework Microcrystals
, 2019 Herein, we demonstrated a steric-hindrance-controlled laser switch in pure metal–organic framework (MOF) microcrystals. The well-faceted MOF microwires with aggregation-induced emission (AIE) lumnogens as linkers function as typical Fabry–Pérot ...
