The irradiation of ruthenium-sulfur dioxide complexes of general formula trans-[Ru(II)(NH(3))(4)(SO(2))X]Y with laser light at low temperature results in linkage isomerization of SO(2), starting with eta(1)-planar S-bound to eta(2)-side S,O-bound SO(2). The solid-state photoreaction proceeds with retention of sample crystallinity. Following work on trans-[Ru(NH(3))(4)Cl(eta(1)-SO(2))]Cl and tra...

We study the effective interaction mediated by strongly coupled Coulomb fluids between dielectric surfaces carrying quenched, random monopolar charges with equal mean and variance, both when the Coulomb fluid consists only of mobile multivalent counterions and when it consists of an asymmetric ionic mixture containing multivalent and monovalent (salt) ions in equilibrium with an aqueous bulk re...

The interactions of an anionic redox-active dye Alizarin Red S (ARS) with novel N-hydroxyethyl-3-alkyloxypyridinium surfactants 1-(2-hydroxyethyl)-3-(tetradecyloxy)pyridinium bromide, [HEC14OPyBr], and 1-(2-hydroxyethyl)-3-(hexadecyloxy)pyridinium bromide, [HEC16OPyBr], were investigated in an aqueous solution for the first time with an attempt to obtain comprehensive knowledge of oppositely ch...

Cyclic voltammetry measurements on imidazolic ionic liquids with sulfonic acid groups and bisulfate counterions revealed that they work as efficient reservoirs of sulfuric are able to dose it demand uphold an catalysis.

Molecular Simulation Investigations In article number 2206382, Mao Wang and Jianwen Jiang design a nanofluidic diode based on hybrid-bilayer covalent organic framework. Through molecular simulation, remarkable behavior is observed. Further analysis reveals that the synergistic effect of counterions in nanopore has positive impact rectification.

Conducting polymers are of interest for a broad range applications from bioelectronics to thermoelectrics. The factors that govern their complex charge transport physics include the structural disorder present in these highly doped polymer films and Coulombic interactions between electronic carriers dopant counterions. Previous studies have shown at low doping levels strongly trapped vicinity c...

Carbon nanotubes have attracted considerable attention since their discovery,[1] and have recently been the focus of intensive investigations. Studies have revealed that nanotubes exhibit extraordinary electronic properties.[2,3] Nanotubes have been shown to ignite upon exposure to short-range flashes of light,[2] and recently ultrafast carbon-nanotubebased transistors have been shown to outper...

We investigated the swelling behavior and density distributions of polyion segments and multivalent counterions in polyelectrolyte brushes within a primitive model that represents both polyion segments and salt ions as charged spheres and the solvent as a continuous dielectric medium. The numerical performance of a previously proposed nonlocal density functional theory (NLDFT) was tested with M...

We use small-angle x-ray scattering (SAXS) as a tool to study the binding of proteins to spherical polyelectrolyte brushes (SPB) in situ. The SPB consists of a solid core of approximately 100 nm diam onto which long polyelectrolyte chains [poly(styrene sulfonic acid, PSS) and poly(acrylic acid, PAA)] have been densely grafted. The proteins used in this investigation, Bovine Serum Albumine (BSA)...
