The structures of mixtures of ionic liquids (ILs) featuring a common 1-butyl-3-methylimidazolium ([C4C1im](+)) cation but different anions have been investigated both experimentally and computationally. (1)H and (13)C NMR of the ILs and their mixtures has been performed both on the undiluted liquids and those diluted by CD2Cl2. These experiments have been complemented by quantum chemical densit...

Bismuth containing compounds are of particular interest for optical or photo-luminescent applications in sensing, bio-imaging, telecommunications, and opto-electronics as components non-toxic extremely dense liquids. Bismuth(III) halometallates form highly colored novel ionic liquid based solvents which experimental characterization fundamental understanding limited. In this work, incorporating...

a pvc-based membrane containing cerium phosphate was developed. unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. the response of molybdate selective electrode based on this membrane was perfectly linear in the concentratio...

We analyze the effects of an externally applied electric field on thermal fluctuations for a binary electrolyte fluid. We show that the fluctuating Poisson-Nernst-Planck (PNP) equations for charged multispecies diffusion coupled with the fluctuating fluid momentum equation result in enhanced charge transport via a mechanism distinct from the well-known enhancement of mass transport that accompa...

Two chelated orthoborate ionic liquids (ILs), 1-butyl-3-methylimidazolium bis(oxalato)borate ([Bmim][BOB]) and 1-hexyl-3-methylimidazolium bis(oxalato)borate ([Hmim][BOB]), were prepared and characterized. Their thermodynamic properties were studied using adiabatic calorimetry and differential scanning calorimetry (DSC). The thermodynamic properties of the two ILs were evaluated and compared wi...

Solid polymer electrolytes (SPEs) have the potential to increase both the energy density and stability of lithium-based batteries, but low Li+ conductivity remains a barrier to technological viability. SPEs are designed to maximize Li+ diffusivity relative to the anion while maintaining sufficient salt solubility. It is thus remarkable that poly(ethylene oxide) (PEO), the most widely used SPE, ...

The asymmetric unit of the crystal structure of the title compound, C(2)H(10)N(2) (2+)·Cl(2)I(-)·Cl(-), contains two ethyl-ene-diammonium cations, two [ICl(2)](-) anions and two Cl(-) anions, of which one cation, one [ICl(2)](-) anion and one Cl(-) anion have site symmetry 2, with the mid-point of the C-C bond of the cation, the I atom of [ICl(2)](-) anion and the Cl(-) anion located on the two...

Our objective was to evaluate the effectiveness of a low dietary cation-anion balance (DCAB) in preventing milk fever and udder edema in dry cows consuming a high-Ca diet and to evaluate the effect of this diet on calves delivered by these cows. Seventy primiparous or multiparous cows and 50 pregnant heifers were offered alfalfa hay-based diets beginning 4 wk before their projected calving date...

The crystal structure of the title compound, (C24H20P)2[Fe(C36H20N4)(CN)2]·2C3H6O, is constructed from a tetra-hedral Ph4P(+) (tetra-phenyl-phospho-nium) cation, one [Fe(tbp)(CN)2](2-) anion (tbp = tetra-benzoporphyrin in its doubly deprotonated form), located on a centre of inversion, and an acetone mol-ecule as crystallization solvent. Since the mol-ecular structure of the M(tbp) moiety is in...
