Electrodialysis for Salt Purification Electrodialysis for Salt Purification

In electrodialysis, an electrical potential drives ions across membranes to effect separations. However, typical ion-exchange membranes show minimal selectivity between monovalent and divalent ions, which is important for applications such as water softening and salt purification. In contrast, we recently found that polyelectrolyte multilayers adsorbed on cation-exchange membranes give rise to an electrodialysis K+/Mg2+ selectivity >90.

Rapid Antibody Digestion in Protease-Containing Membranes Rapid Antibody Digestion in Protease-Containing Membranes

Proteolytic digestion followed by mass spectrometry (MS) analysis of the resulting peptides is the most common method to characterize antibodies and investigate post-translational modifications. This work develops digestion in protease-containing membranes for rapid (<1 min), controlled digestion.
