We show that the interaction of trivalent electrolytes with biological nanopores occurs via ion-specific adsorption yielding differential modulation ion conduction and selectivity inversion.

Ab initio molecular orbital calculations of electron distribution in tetramethylammonium ion and its uncharged isoelectronic analogue, neopentane, have been carried out. Comparison of the two compounds permits a detailed description of the delocalization of the positive charge of tetramethylammonium ion. The van der Waals surface of this ion is found to be characterized by "patches" of positive...

The interaction of ion channels with the actin-based cytoskeleton in epithelial cells not only maintains the polarized expression of ion channels within specific membrane domains, it also functions in the intracellular trafficking and regulation of channel activity. Initial evidence supporting an interaction between epithelial ion channels and the actin-based cytoskeleton came from patch-clamp ...

background: combination of glycation and oxidation is associated with diabetes mellitus. the aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ros) in rat hepatocyte suspension.  methods: glycated albumin was prepared by incubation of bovine serum albumin with 100 mm glucose in 0.3 m phosphate buffer a...

2014 A very simplified description of angular distribution hyperfine interaction techniques is given, with a view to presenting their applications in ion-implantation studies of metals. Some typical experiments are reviewed. The latter part of the paper is devoted to a discussion of radiation damage effects in hyperfine interaction studies after ion-implantation.

We investigate suprathermal ion dynamics in simple magnetized toroidal plasmas in the presence of electrostatic turbulence driven by the ideal interchange instability. Turbulent fields from fluid simulations are used in the nonrelativistic equation of ion motion to compute suprathermal tracer ion trajectories. Suprathermal ion dispersion starts with a brief ballistic phase, during which particl...

interaction of pb(ii) ion with modified banana shell (mbs) and banana shell (bs) during adsorption fromaqueous solution were investigated. batch experiments were carried out to investigate the effect of contact time,ph, and idmid ion concentration on adsorption efficiency. the favorable pll for maxim= pb(ii) adsorptionwas at 5.0. for the investigated imoi) concentrations (10-80 mph), maximum ad...

Driving an ion at a motional sideband transition induces the Jaynes--Cummings (JC) interaction. This JC interaction creates anharmonic ladder of eigenstates, resulting in suppression phonon hopping due to energy conservation. Here, we realize blockade presence multiple local phonons trapped-ion chain. Our work establishes key technological component for quantum simulation with bosonic particles...
