Seven copperIJII) complexes with the less bulky (compared to bis-phenyl-substituted imidazoles used in our previous studies) monodentate 2-phenylimidazole (LH) ligand have been prepared from the general Cu/ X−/LH (X− = NO3 −, ClO4 −, BF4 −, SO4 2−, Cl−) reaction system and were structurally characterized by X-ray diffraction. Interestingly, the choice of reaction/crystallization solvent provide...

Single-channel currents through GABA- and glycine-activated chloride channels of post-natal tissue-cultured hippocampal neurons were measured to determine their anion selectivity and their concentration dependence of permeation. Current-voltage relations for both agonists displayed rectification with single-channel conductance increasing at positive potentials. Permeabilities determined from re...

One-pot reaction of CuX2 salts (X = NO3, Cl, ClO4, AcO, SO4/2), 2-Hydroxypyrimidine hydrochloride (2-Hpymo·HCl) and 4,4′-bipyridine (4,4′-bpy), in H2O : ethanol : ammonia (20 : 10 : 5) solution, leads to isomorphous extended layered materials of type [Cu3(l-OH)2(l-Cl)2(l-2-pymo)(l-4,4-bpy)3]nXn·mH2O (X = NO3 (1a), Cl (1b), ClO4 (1c), AcO (1d), SO4/2 (1e)). The single crystal X-ray crystallograp...

The SLC26 transporters are a family of mostly luminal Cl- and HCO3- transporters. The transport mechanism and the Cl-/HCO3- stoichiometry are not known for any member of the family. To address these questions, we simultaneously measured the HCO3- and Cl- fluxes and the current or membrane potential of slc26a3 and slc26a6 expressed in Xenopus laevis oocytes and the current of the transporters ex...

The syntheses and characterization of four new hybrid coordination networks based on lanthanide ions (Ln = Nd, Sm) and 1,3-carboxymethylimidazolium (L) salt in the presence of oxalic acid (H2ox) are reported. The influence of the synthesis parameters, such as the nature of the lanthanide ion (Nd3+ or Sm3+), the nature of the imidazolium source (chloride [H2L][Cl] or zwitterionic [HL] form) and ...

Single channel currents though apical membrane Cl channels of the secretory epithelial cell line T84 were measured to determine the anionic selectivity and concentration dependence of permeation. The current-voltage relation was rectified with single channel conductance increasing at positive potentials. At 0 mV the single channel conductance was 41 +/- 2 pS. Permeability, determined from rever...

Single crystals of Cs2(UO2)(NO3)Cl3 were prepared by a hydrothermal method at 205 ◦C. The crystal structure has been solved by Direct Methods: monoclinic, P21/n, a = 10.3748(13), b = 9.4683(13), c = 12.5535(16) Å, β = 110.280(2)◦ , V = 1156.7(3) Å3, R1 = 0.029. In the structure, strongly bonded linear uranyl cations UO2 are equatorially coordinated by two O and three Cl atoms to form (UO2)Cl3O2...

This work has investigated the influence of common groundwater anions (Cl , NO3 , SO4 and HCO3 ) on the corrosion behaviour and associated removal of copper (Cu) and zinc (Zn) ions onto nanoscale zerovalent iron particles (nZVI). After 16 week exposure to solutions containing each anion at 10 mM concentrations, nZVI was observed to corrode into different iron (hydr)oxide phases (determined usin...

We measured the depth profiles of soluble ions in the Dome Fuji (Antarctica) ice core to search for possible paleoclimate indications of seasonal climate variations in the last glacial period. A 523mm long core section between 587.65 and 588.18m depth was selected for this pilot study, and the high-resolution chemical analysis was done on 2mm thick samples. Our results indicate that anion– cati...
