Fluoropolymer Membranes for Membrane Distillation and Membrane Crystallization [PDF]
Polymers, 2022 Fluoropolymer membranes are applied in membrane operations such as membrane distillation and membrane crystallization where hydrophobic porous membranes act as a physical barrier separating two phases. Due to their hydrophobic nature, only gaseous molecules are allowed to pass through the membrane and are collected on the permeate side, while the ...

Self-interaction chromatography as a tool for optimizing conditions for membrane protein crystallization [PDF]
, 2010 The second virial coefficient, or B value, is a measurement of how well a protein interacts with itself in solution. These interactions can lead to protein crystallization or precipitation, depending on their strength, with a narrow range of B values ...
