Study of Ion Transport across Amphoteric Ion Exchange Membrane. I. Electroconductive Membrane Permeability

Synthesis, Characterization and Transport Properties of Novel Ion-exchange Nanocomposite Membrane Containing In-situ Formed ZnO Nanoparticles

A  new  type  of  cation-exchange  nanocomposite  membranes  was prepared  by  in-situ  formation  of  ZnO  nanoparticles  in  a  blend containing  sulfonated  poly  (2,6-dimethyl-1,4-phenylene  oxide)  and sulfonated polyvinylchloride  via  a  simple  one-step  chemical method.  As-synthesized  nanocomposite  membranes were characterized  using  Fourier  transform  infrared  spectroscopy, scan...

Membrane composition and ion-permeability in extremophiles

Protons and sodium ions are the only used coupling ions in energy transduction in Bacteria and Archaea. At their growth temperature, the permeability of the cytoplasmic membrane of thermophilic bacteria to protons is high as compared to sodium ions. In some thermophiles, therefore, sodium is the sole energy coupling ion. Comparison of the protonand sodium permeability of the membranes of variet...

Selective Transport of Propylene by Silver Ion Complex Through an Immobilized Liquid Membrane

Electrochemical Properties and Antibacterial Activity of Polyvinyl Chloride Supported Silver Molybdate Ion-Exchange Composite Membrane

Polyvinyl chloride supported silver molybdate composite material is used to develop by solution casting method. This membrane was characterized by various instrumental techniques such as Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) analyses. These characterizations are used to understand the functional groups,thermal sta...

Membrane ion transport in non-excitable tissues.

The facilitated movement of ions across cell membranes can be characterized as occurring through active (ATP-dependent), secondary active (coupled), or passive transport processes. Each of these processes is mediated by a diverse group of membrane proteins. Over the past fifteen years, studies of membrane transport in C. elegans have benefited from the fact that worms are anatomically simple, e...
