Steric Effects on Electroosmotic Nano-Thrusters under High Zeta Potentials
Mathematics, 2021 Here, space electroosmotic thrusters in a rigid nanochannel with high wall zeta potentials are investigated numerically, for the first time, considering the effect of finite size of the ionic species. The effect, which is called a steric effect, is often

Steric and Stereochemical Modulation in Pyridyl- and Quinolyl-Containing Ligands
Molecules, 2016 Nitrogen-containing pyridine and quinoline are outstanding platforms on which excellent ionophores and sensors for metal ions can be built. Steric and stereochemical effects can be used to modulate the affinity and selectivity of such ligands toward ...

Topological Steric Effect Index and Its Application. [PDF]
ChemInform, 2004 This paper proposed a Topological Steric Effect Index (TSEI) of a group based on the relative specific volume of the reaction center screened by the atoms of the substituents. Investigated results show good correlations between the parameter TSEI and the dihedral angles between both phenyl rings determined by photoelectron spectroscopy for 7 ...
