Ion Transport in the Gut

Ion transport in the gut.

The in vitro preparation of the small intestine of the rat is well suited for studies of ion transport. Data from this preparation indicate that the passage of water and electro-lytes across the intestinal epithelium depends on active transport. Glycolysis seems to be involved as a source of energy for the transport of ions from the mucosal to the serosal aspect of the intestinal wall. LITERATU...

Ion Transport in Acidophiles

Hybrid Molten/Solid In2O3-Bi2O3 Oxygen Ion Transport Membranes

The hybrid molten/solid In2O3 - 30-48 wt.% Bi2O3 oxide materials were studied with respect to their transport properties. The conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe DC, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. We show that the...

Characterization of Lithium Ion Transport Via Dialysis Process

Dialysis is a membrane based separation process in which the concentration gradient across the membrane is the driving force resulting in a flow of material from one side <span style="font-size: 10pt; ...

Ion transport in nanofluidic channels.

In this tutorial review, recent developments in modeling and experimental studies on nanofludics were reported. Nanofluidic studies were categorized into two groups depending on the characteristic length scale. When the size of the nanochannels and pores is 5-100 nm, electrostatic interactions are dominant, and ion and fluid flow can be analyzed by continuum dynamics. Various nanofluidic device...
