Transport and Sorption of Organic Gases in Activated Carbon

Journal of Environmental Engineering, 1996
The relationships among adsorption-desorption kinetics, equilibrium partitioning, and fixed-column breakthrough curves are elucidated for airborne benzene and vinyl chloride on activated carbon grains and fibers. An electrobalance is used to measure adsorption/desorption kinetics and to obtain equilibrium partitioning data; column experiments are ...

Transport and Sorption of Water Vapor in Activated Carbon

Journal of Environmental Engineering, 1996
Control of organic vapors by adsorption on activated carbon can be impacted by the presence of water vapor in the gas stream. As a foundation to better understand this issue, the transport and sorption of water vapor within activated carbon grains were studied.

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

Active Learning of Anharmonic Phonon Transport Across Carbon Allotropes

The Journal of Physical Chemistry Letters
Machine-learning potentials (MLPs) face significant challenges in sampling anharmonic lattice dynamics due to computational bottlenecks. This work presents an active learning (AL) framework that integrates pretrained potentials with committee models to overcome these limitations.
