Transport of volatile solutes through AQP1

Teflon Af Membrane Transport of Organic Solutes

Transalveolar transport of large polar solutes (sucrose, inulin, and dextran).

The in vivo transalveolar transport of three large polar solutes, sucrose, inulin, and dextran (mol wt 60,000-90,00), was compared with the transport of urea in saline-filled dog lung. Apparent permeability coefficents (p', in cm X sec-1 X 10(6)) were as follows; urea: 2.4 +/- 0.28 (SD) greater than sucrose: 0.64 +/- 0.31 (P less than 0.001) greater than inulin: 0.12 +/- .05 (P less than 0.001)...

Transport of Gas and Solutes in Permeable Estuarine Sediments

The long-term goals are 1) to assess the role of small gas bubbles in shallow sandy coastal sediment for sediment geotechnical properties, the transport of solutes across the sediment-water interface and the biogeochemical processes in the sediment surface layer 2) to develop and apply an acoustic technique for the detection and quantification of small gas bubbles in sandy sediment at a high sp...

Selective Mass Transport of CO2 Containing Mixtures through Zeolite Membranes

In this work, the main aspects regarding the permeation of mixtures containing CO2 and permanent gases such as H2 , N2 and CH4 through zeolite membranes have been investigated, focusing on the description of the mass transport mechanisms taking place inside the pores. First, a brief overview about the performance of the main zeolite membranes used in gas separation (e.g. DDR, CHA, AEI, FAU, etc...

Transport of nonsorbing solutes in a streambed with bedforms

Previous studies of hyporheic zone focused largely on the net mass transfer of solutes between stream and streambed. Solute transport processes within the bed has attracted less investigation. In this study, we combined flume experiments and numerical simulations to examine solute transport processes in a streambed with periodic bedforms. Solute originating from the stream was subjected to adve...
