Nanopores with controlled profiles in track-etched membranes
The production of the track-etched membranes is well known in membrane science. Latent ion tracks are the result of the passage of swift ions through solid matter, they can be etched selectively in many materials. As a result, conical, cylindrical or other shape channels can be obtained. The increasing interest in polymer track-etched membranes with nano-channels is connected with the developme...
متن کاملLow-voltage electroosmotic pumps fabricated from track-etched polymer membranes.
Track-etched polymer membranes are used to realize low-voltage electroosmotic (EO) pumps. The nanopores in polycarbonate (PC) and polyethylene terephthalate (PET) membranes were fabricated by the track-etching technique, the pore diameter was controlled in the range of 100 to 250 nm by adjusting the etching time. The results show that these EO pumps can provide high flow rates at low applied vo...

متن کاملMercury-sensitive water channels as possible sensors of water potentials in pollen
The growing pollen tube is central to plant reproduction and is a long-standing model for cellular tip growth in biology. Rapid osmotically driven growth is maintained under variable conditions, which requires osmosensing and regulation. This study explores the mechanism of water entry and the potential role of osmosensory regulation in maintaining pollen growth. The osmotic permeability of the...
متن کاملRemoval of Dilute Benzene in Water through Ionic Liquid/Poly(Vinyl Chloride) Membranes by Pervaporation
This paper focuses on the effects of the addition of an ionic liquid, 1-Allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([ABIM]TFSI), which has a high affinity for benzene, into the poly(vinyl chloride) (PVC) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. When aqueous solutions of 100～500 ppm benzene were permeated ...
