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 ...

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 ...

Journal of the Chemical Society, Faraday Transactions, 1990
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 ...

Experiments in membrane protein crystallization
Journal of Crystal Growth, 1988Experiments have been carried out aimed at obtaining crystals of three integral membrane proteins: phospholipase A, cytochrome-c reductase and cytochrome-c oxidase. Crystals, in the form of platelets and bipyramids, as well as several micro-crystal forms have been obtained of phospholipase A from the outer membrane of Escherichia coli.

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.

Crystallization of Membrane Proteins
1999Crystallization of membrane proteins is one of the most recent developments in protein crystal growth; in 1980, for the first time, two membrane proteins were successfully crystallized, bacteriorhodopsin (1) and porin (2). Since then, a number of membrane proteins (about 30) yielded three-dimensional crystals.

Crystallization of membrane proteins in Cubo
2002Our understanding of lipidic cubic phases for the crystallization of membrane proteins has advanced greatly since the inception of the concept in 1996, and the method is becoming well accepted. Several protocols that allow the efficient screening of crystallization conditions and handling of crystals are presented.

Membrane assisted crystallization of salt crystals: membrane modeling
2018Crystallization is one of the most widely applied separation processes in the chemical industry and the interest to combine membrane operations and crystallization has increased recently. Membrane crystallization (MCr) is emerging as a promising technique with some important advantages with respect to traditional crystallization processes: well ...

Crystallization of Membrane Proteins: An Overview
2017Membrane proteins are crucial components of cellular membranes and are responsible for a variety of physiological functions. The advent of new tools and technologies for structural biology of membrane proteins has led to a significant increase in the number of structures deposited to the Protein Data Bank during the past decade.

Crystallization of Membrane Proteins in Bicelles
2012The structural biology of membrane proteins remains a challenging field, partly due to the difficulty in obtaining high-quality crystals. We developed the bicelle method as a tool to aid with the production of membrane protein crystals. Bicelles are bilayer discs that are formed by a mixture of a detergent and a lipid.
