Molecular Mechanistic Insights into the Ionic-Strength-Controlled Interfacial Behavior of Proteins on a TiO2 Surface

open access: yes, 2021
By adjusting the ionic strengths through changing the concentration of the buffer ions, the molecular force and the interfacial behavior of cytochrome c (Cyt c) and TiO2 are systematically studied.

Enhancement of force generated by individual myosin heads in skinned rabbit psoas muscle fibers at low ionic strength. [PDF]

open access: yesPLoS ONE, 2013
Although evidence has been presented that, at low ionic strength, myosin heads in relaxed skeletal muscle fibers form linkages with actin filaments, the effect of low ionic strength on contraction characteristics of Ca(2+)-activated muscle fibers has not

Modeling Ionic Strength Effects on Hollow-Fiber Nanofiltration Membrane Mass Transfer

open access: yesMembranes, 2018
In this research, we investigated the influence of feedwater ionic strength on diffusion of divalent ions through a hollow-fiber nanofiltration membrane. The results indicated that solute flux of magnesium was increased as a result of elevating the ionic

Sorption of Se(-II) on illite, MX-80 bentonite, shale, and limestone in Na–Ca–Cl solutions

open access: yesNuclear Engineering and Technology, 2022
Selenium has been identified as an element of interest for the safety assessment of a deep geological repository (DGR) for used nuclear fuel. In Canada, groundwaters at DGR depths in sedimentary rocks have been observed to have a high ionic strength ...

Correlation between eletrokinetic mobility and ionic dyes adsorption of Moroccan stevensite [PDF]

open access: yes, 2010
This study aims at establishing a correlation between the electrical charge of Moroccan stevensite particles and ionic dyes adsorption. The electrophoretic mobility, (Ue), of the stevensite particles in water, was measured at pH 2.5–12 by ...

Contraction of Stress Fibers Extracted from Smooth Muscle Cells: Effects of Varying Ionic Strength

open access: yesJournal of Biomechanical Science and Engineering, 2012
Actin stress fibers (SFs) play a key role in regulation of cell adhesion, but the biochemical and biophysical properties intrinsic to SFs remain unclear. Here we extracted SFs from rat embryonic smooth muscle cells by deroofing, and evaluated the effects

Empirical models to determine ions concentrations in lithium brines with high ionic strength

open access: yesResults in Engineering, 2023
Argentina Puna brines are complex systems in which ions such as Na+, K+, Li+, Mg2+, Ca2+, SO42−, and B4O72− are presents. To obtain lithium carbonate from brines, they must be treated in order to increase its lithium concentrations and to eliminate the ...
