Controlling the Assembly of PdII/Bianthryl‐Based Monomeric and Dimeric Interlocked Cages by Steric Effects

open access: yesChemistryEurope, 2023
In the energy landscape of coordination‐driven self‐assembly processes, the isolation of kinetically formed supramolecular cages has long been identified as a challenging task.

Topological Steric Effect Index and Its Application. [PDF]

open access: yesChemInform, 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 ...

Analytical interfacial layer model for the capacitance and electrokinetics of charged aqueous interfaces [PDF]

open access: yes, 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.

An NMR Study on How Steric Effects Affect Synergistic Effects in Surfactant Mixtures

open access: yesChinese Journal of Magnetic Resonance, 2018
NMR spectra of aqueous solutions of cetyltrimethylammonium bromide (CTAB)/triton X-100 (TX-100), sodium dodecyl sulfate (SDS)/TX-100 and CTAB/TX-100/SDS surfactant mixtures were acquired.

Role of anisotropy for protein-protein encounter [PDF]

open access: yes, 2010
Protein-protein interactions comprise both transport and reaction steps. During the transport step, anisotropy of proteins and their complexes is important both for hydrodynamic diffusion and accessibility of the binding site.

Uncovering the Mechanism of Aggregation of Human Transthyretin. [PDF]

open access: yes, 2015
The tetrameric thyroxine transport protein transthyretin (TTR) forms amyloid fibrils upon dissociation and monomer unfolding. The aggregation of transthyretin has been reported as the cause of the life-threatening transthyretin amyloidosis.

Outlining the Roles of Membrane-Foulant and Foulant-Foulant Interactions in Organic Fouling During Microfiltration and Ultrafiltration: A Mini-Review

open access: yesFrontiers in Chemistry, 2020
Membrane fouling remains a notorious problem in microfiltration (MF) and ultrafiltration (UF), and a systematic understanding of the fouling mechanisms is fundamental for solving this problem. Given a wide assortment of fouling studies in the literature,

Steric Effects on Space Electroosmotic Thrusters in Soft Nanochannels

open access: yesMathematics, 2021
The influence of steric effects on the performances of space electroosmotic thrusters (EOTs) was numerically delineated in soft nanochannels for which its walls are covered with polyelectrolyte materials.

Analysis of the conformational profiles of fenamates shows route towards novel, higher accuracy, force-fields for pharmaceuticals [PDF]

open access: yes, 2015
In traditional molecular mechanics force fields, intramolecular non-bonded interactions are modelled as intermolecular interactions, and the form of the torsion potential is based on the conformational profiles of small organic molecules.
