Membrane Distillation Crystallizer
2019Membrane distillation crystallization (MDC) is an innovative concept of combining the strengths of membrane distillation into crystallization processes because crystallization is one of the major unit operations in chemical industries. The hybrid technology is of growing interest due to some important advantages, such as the controlled rates of ...

Strategies for crystallizing membrane proteins
Journal of Bioenergetics and Biomembranes, 1996Crystallizing membrane proteins remains a challenging endeavor despite the increasing number of membrane protein structures solved by X-ray crystallography. The critical factors in determining the success of the crystallization experiments are the purification and preparation of membrane protein samples.

Antisolvent membrane crystallization of pharmaceutical compounds
Journal of Pharmaceutical Sciences, 2009This article describes a modification of the conventional membrane crystallization technique in which a membrane is used to dose the solvent/antisolvent composition to generate supersaturation and induce crystallization in a drug solution. Two operative configurations are proposed: (a) solvent/antisolvent demixing crystallization, where the solvent is ...

Properties of porous, single-crystal membranes have been modelled for Langmuir's isotherm assuming that entry to and exit from the crystal proceeds via an externally adsorbed layer. The potential moderating role of surface processes upon steady flow depends strongly upon temperature and upon the difference in activation energy for escape from the ...

Calcium Oxalate-Crystal Membrane Interactions
The Journal of Urology, 1996Urolithiasis is clearly a multifaceted process, progressing from urine supersaturation to the formation of mature renal calculi. Retention of microcrystals by the urothelium is a critical event in stone maturation. Membrane phospholipids appear to be involved in the attachment of stone crystals to kidney epithelium.The current study quantitates crystal-

Crystallization of intrinsic membrane proteins
Journal of Bioenergetics and Biomembranes, 1984After many years of discouraging failures, it is now possible to crystallize the intrinsic membrane proteins and to obtain structural information from diffraction studies on the crystals. The strategy for the crystallization consists of depletion of boundary phospholipids from the protein and complex formation with specific ligands.

MEMBRANES FOR IMPROVED MEMBRANE DISTILLATION AND MEMBRANE CRYSTALLIZATION
2020Symmetric PVDF porous membranes with Graphene flakes have been prepared by phase inversion technique and used to equip membrane distillation devices. Very high water flux and total salt rejection have been obtained with long-term stability and resistance to fouling.
