para-Selective C-H amidation of simple arenes with nitriles [PDF]
, 2015 A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred.

Steric effects in adsorption of ions from mixed electrolytes into microporous carbon [PDF]
, 2012 With the goal to improve the capacitance in electrochemical double-layer capacitors (EDLCs) many studies on pore size/ion size relationship have been undertaken to achieve a better understanding of the charge storage mechanism in the electrochemical ...

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

Kinetics of the reaction of 5-substituted orotic acids with diazodiphenylmethane [PDF]
Journal of the Serbian Chemical Society, 2004 Rate konstants for the reaction of eight 5-substituted orotic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) were determined at 30 ºC by the known spectrophotometric method.

Analytical interfacial layer model for the capacitance and electrokinetics of charged aqueous interfaces [PDF]
, 2018 We construct an analytical model to account for the influence of the subnanometer-wide interfacial layer on the differential capacitance and the electro-osmotic mobility of solid–electrolyte interfaces.

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 ...
