Highly stable membrane comprising MOF nanosheets and graphene oxide for ultra-permeable nanofiltration [PDF]

open access: yes, 2022
The separation application of two-dimensional (2D) material membrane, e.g., graphene oxide (GO) membrane, has long been limited by the low stability and uncontrollable permeability originated from their severe swelling in water and uneven interlayer ...

Evaluation of nanofiltration for the purification of an organic acid fermentation broth [PDF]

open access: yes, 2006
This study focuses on a possible elimination of glucose from a sodium lactate fermentation broth by nanofiltration (NF). The results obtained with single-solute solutions indicate that glucose is clearly more retained that sodium lactate.
