Slow anion channels in the plasma membrane of guard cells have been suggested to constitute an important control mechanism for long-term ion efflux, which produces stomatal closing. ldentification of pharmacological blockers of these slow anion channels is instrumental for understanding plant anion channel function and structure. Patch clamp studies were performed on guard cell protoplasts to i...

An intramolecular palladium catalysed carbometalation followed by anion capture achieves construction of a model comprised of the A ring of Vitamin D oxygen analogues.

background: the mechanism of hypoxic pulmonary vasoconstriction (hpv) is still debatable. it has been proposed that reactive oxygen species (ros) might be involved in hpv. however, there is no special transporter for superoxide anion in the cell membrane and it may release from the cells via anion exchanger. therefore, the aim of this study was to investigate the interaction of ros and anion ex...

The work is devoted to the theoretical and experimental study of electrochemical characteristics closo-decaborate anion. regions transformations [B10H10]2– anion for non-aqueous solvents different structures (acetonitrile, dichloromethane, tetrahydrofuran) have been studied by method cyclic voltammetry. It has shown that, under conditions anodic oxidation, a dimerization product, [B20H18]2– ani...

optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano rods (zonrs) as a nucleus layer were fabricated on the indium tin oxide (ito) by chronoamperometry (ca) in a...

lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. these are subsequently recovered from the resin by 0.5m ammonium citrate eluent at ph 2.0. under optimized conditions, quantitative recovery was ...

Anion ordering is a promising route to engineer physical properties in functional heteroanionic materials. A central challenge the study of anion-ordered compounds lies developing robust synt...
