Multi-ionic Potential and Membrane Permeability Matrix. I. NaCl–CsCl Bi-ionic System with a Cation Exchange Membrane

Ionic gradients, membrane potential and ionic currents

The neuronal plasma membrane delimits the whole neuron, cell body, dendrites, dendritic spines, axon and axon terminals. It is a barrier between the intracellular and extracellular environments. The general structure of the neuronal plasma membrane is similar to that of other plasma membranes. It is made up of proteins inserted in a lipid bilayer, forming as a whole a ‘fl uid mosaic’ ( Figure 3...

Erythrocyte Membrane Cation Permeability

A B S T R A C T Cetiedil has been reported to relieve painful crises in sickle cell anemia and to have antisickling properties in vitro. The drug alters neither oxygen affinity nor the solubility of deoxyhemoglobin S. Because the viscosity of the erythrocyte interior and the kinetics ofgelation are dependent on the concentration of hemoglobin, we postulated that cetiedil might inhibit sickling ...

Ionic Copolymers for Alkaline Anion Exchange Membrane Fuel Cells (AAEMFCs)

High-flux ionic diodes, ionic transistors and ionic amplifiers based on external ion concentration polarization by an ion exchange membrane: a new scalable ionic circuit platform.

A microfluidic ion exchange membrane hybrid chip is fabricated using polymer-based, lithography-free methods to achieve ionic diode, transistor and amplifier functionalities with the same four-terminal design. The high ionic flux (>100 μA) feature of the chip can enable a scalable integrated ionic circuit platform for micro-total-analytical systems.

Electrodialysis Heterogeneous Anion Exchange Membranes Filled with TiO2 Nanoparticles: Membranes' Fabrication and Characterization

In the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. Titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. The effect of TiO2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. Membrane wate...
