Vapor-phase method makes membranes for gas separation Scalable deposition technique yields chemically selective film of zeolitic imidazolate framework (ZIF) by Mitch Jacoby ...

A limitation of polymeric membranes for gas and vapour transport is the so-called permeability-selectivity trade-off, first reported by Robeson et al. in 1991 [3] and then further updated [4]. This ...

Trends, opportunity and forecast in the global gas separation membrane market to 2028 by material type (polyimide & polyaramide, polysulfone, cellulose acetate, and others), module (hollow fiber ...

LONDON, April 23, 2020 /PRNewswire/ -- DuPont has been a pioneer in fire safety for over 50 years and introduced its Tyvek® FireCurb® Housewrap breather membrane for buildings in 2013. As ...

Comparing the two mechanisms, it is immediately clear why nanobubble-based membranes are such a good idea: the vapour transport is much less efficient than the liquid–liquid transfer because of ...

Membrane distillation involves a thin, water-repellant membrane that exploits vapor pressure differences between hotter impure liquid, called "feedwater," and colder purified water, called "permeate." ...

The Hiden Analytical HPR-40 Membrane Inlet Mass Spectrometer series now feature an extended range of submersible insertion probes and flow-through semipermeable membrane interfaces, specifically ...

To investigate the role of liquid/vapour interfaces in nanofluidic transport, we designed osmosis membranes comprising nanopores with short hydrophobic regions of tunable length that trap ...

In China, new legal regulations prescribe the recovery of petrol vapour at filling stations (vent processing) in especially polluted regions like Beijing or Shanghai. Due to these new conditions ...
