2-butoxyethanol as a Draw Solution for Forward Osmotic Application

Sano K., Ide T., Imada T., Toshiba Corporation, JP

As a draw solution, 2-butoxyethanol (2BE) was examined for forward osmotic application such as power generation and desalination. As forward osmosis experiments, simple hand made cell with a membrane of 5mm in diameter. Under stirring [...]

Investigation of the Concentration Polarization effect on Nanoparticles using radial micro-nanofluidic devices

Aïzel K., Fouillet Y., Pudda C., Chabrol C., Texier-Nogues I., CEA-LETI, FR

We perform ICP using radial silicon nanojunction geometries fabricated by single standard silicon microfabrication for proof of concept concentration operation over 50nm polystyrene nanobeads.We call the devices “Ring like devices” because of the circular shape [...]
