Ionic Transport in Pores in Activated Carbons for EDLCs

Journal of The Electrochemical Society, 2006
The transport properties and morphology of an activated carbon containing macro-, meso-, and micropores were studied and compared to a sophisticated fully nanoporous carbon that almost lacks meso ...

Evidence of carbonic anhydrase activity in skeletal muscle: A role for facilitative carbon dioxide transport

Respiration Physiology, 1974
Abstract Carbon dioxide, water and vascular space were measured in the hind limb of the dog, with blood and plasma perfusion, before and after the administration of acetazolamide. Inhibition of carbonic anhydrase by acetazolamide resulted in a decrease in carbon dioxide space from greater than water space to similar to vascular space.

Transport of Methane, Acetylene, and Acetaldehyde through Activated Carbon

Separation Science and Technology, 1990
Abstract The outlet concentration as a function of time for pulsed and stepped inputs of 100 ppm concentrations of methane, acetylene, and acetaldehyde adsorptives in helium at 1 atm pressure through columns of activated carbon at 25°C were measured and correlated with the solutions to a longitudinal-diffusion model with a linear isotherm.

Charge carrier transport control in activated carbon fibers

Carbon, 2013
Abstract We present the results of measurements of electronic transport in an activated carbon fiber performed over a wide temperature range. The fiber had been subjected to the adsorption of various molecules, one type at a time. The presence of guest molecules inside the fiber’s pores causes significant changes in the electronic transport which has

Surface carbonic anhydrase activity on astrocytes and neurons facilitates lactate transport

Glia, 2003
AbstractA number of studies have provided physiological evidence for extracellular carbonic anhydrase (CA) in brain. Association of extracellular CA with glia has been limited to functional studies of gliotic slices and retinal Muller cells. While astrocytes contain intracellular CA, there has been no direct evidence for surface CA on these cells.

Histochemical Demonstration of Carbonic Anhydrase Activity in Some Epithelia Noted for Active Transport

Acta Physiologica Scandinavica, 1968
AbstractAn improved histochemical method for demonstration of carbonic anhydrase has been applied to a number of epithelia engaged in electrolyte transport.Heavy staining was found close to or in the following regions: Intercellular spaces bordered with folded epithelial membranes (unpigmented epithelium of rabbit ciliary processes, straight segment of

Carbon dioxide transport through enzymatically active synthetic membranes

Chemical Engineering Science, 1975
The facilitated transport of CO2 through thin liquid membranes, Millipore filter membranes, and cross-linked protein membranes has been investigated using a tracer 14CO2 technique. Both the uncatalyzed reactions and the enzymatic reactions catalyzed by carbonic anhydrase in homogeneous solution and immobilized in several membrane configurations were ...

Electric Pulse Discharge Activated Carbon Supercapacitors for Transportation Application

JOM, 2012
ScienceTomorrow is developing a high-speed, low-cost process for synthesizing high-porosity electrodes for electrochemical double-layer capacitors. Four types of coal (lignite, subbituminous, bituminous, and anthracite) were used as precursor materials for spark discharge activation with multiscale porous structure.

Capillary transport in adsorption from liquid phase on activated carbon

AIChE Journal, 1999
AbstractTwo models presented here predict the kinetics of adsorption from solution. The adsorbate is considered to form a capillary separated phase inside the micropores. The transport in the adsorbed phase is modeled as capillary transport under the influences of gradients in capillary pressure.
