Hybrid ceramic membranes for organic solvent nanofiltration
Journal of membrane science, 2020 Uniquely suited to organic solvent nanofiltration (OSN) are hybrid, ceramic-based membranes. The stability of these membranes in the harsh solvents and conditions of industrial process streams is due to the sturdy and inert architecture of the ceramic, while the organic functionalization is responsible for surface and pore properties of the membrane ...

Cellulose membranes for organic solvent nanofiltration
, 2020 Cellulose is an alternative polymer that can be used in Organic Solvent Nanofiltration(OSN) where lack of chemically-stable membranes is a major problem. Cellulose, dueto strong inter and intramolecular hydrogen bonding, is difficult to dissolve in many solvents, which is an advantage for OSN applications.
