Metal-Organic Framework Nanocomposite Thin Films with Interfacial Bindings and Self-Standing Robustness for High Water Flux and Enhanced Ion Selectivity.

ACS Nano, 2018
Metal-organic framework (MOF)-based materials are promising candidates for a range of separation applications. However, the fabrication of self-standing MOF-based thin films remains challenging. Herein, a facile solution casting strategy is developed for

Water‐air flux of dimethylsulfide

Journal of Geophysical Research: Oceans, 2000
The water‐air exchange of dimethylsulfide (DMS) has been measured in a laboratory wind‐wave tank in fresh and seawater. To understand the transport behavior of DMS, its exchange was measured simultaneously with that of O2, SF6, Ne, CH4, and He under varying wind speeds and hydrodynamic conditions. No unpredictable differences between fresh and seawater

Water vapor flux at the sea surface

Boundary-Layer Meteorology, 1989
Methods and instrumentation for determining the rate of evaporation at the sea surface are reviewed. At experimental sites free of local influences, there is a consensus that the evaporation coefficient in neutral conditions C EN = 1.2 × 10−3 at low and moderate wind speeds.

Impact of surface porosity on water flux and structural parameter in forward osmosis

Desalination, 2018
Improving water flux is a crucial objective of research in forward osmosis (FO) technology. A structural parameter is the property of the support layer of the membrane that determines the internal concentration polarization, which is determined by the ...

Automated Flux Chamber for Investigating Gas Flux at Water–Air Interfaces

Environmental Science & Technology, 2012
Aquatic ecosystems are major sources of greenhouse gases (GHG). Representative measurements of GHG fluxes from aquatic ecosystems to the atmosphere are vital for quantitative understanding of relationships between biogeochemistry and climate. Fluxes occur at high temporal variability at diel or longer scales, which are not captured by traditional short-

Fluxes of Carbon, Water and Nutrients

2012
The metabolic and physical processes result in concentration, pressure and temperature differences that generate fluxes within ecosystems and between ecosystems and their surroundings. We apply the same approach combining metabolic and physical processes with transport in the analysis of very different phenomena from water and sugar transport within ...

WATER FLUX IN MOIST SOIL

Soil Science, 1965
That thermal gradients cause moisture transport in soil has been well known for at least 50 years. It is, however, surprising that so little attention has been paid to this phenomenon, since soil in its natural environment is continuously subject to changing temperatures.
