Separation and Recycling of Concentrated Heavy Metal Wastewater by Tube Membrane Distillation Integrated with Crystallization

open access: yesMembranes, 2020
Tube membrane distillation (MD) integrated with a crystallization method is used in this study for the concurrent productions of pure water and salt crystals from concentrated single and mixed system solutions.

Nanobody mediated crystallization of an archeal mechanosensitive channel. [PDF]

open access: yesPLoS ONE, 2013
Mechanosensitive channels (MS) are integral membrane proteins and allow bacteria to survive sudden changes in external osmolarity due to transient opening of their pores.

Treatment of Aniline Wastewater by Membrane Distillation and Crystallization

open access: yesMembranes, 2023
Aniline is a highly toxic organic pollutant with “carcinogenic, teratogenic and mutagenesis” characteristics. In the present paper, a membrane distillation and crystallization (MDCr) process was proposed to achieve zero liquid discharge (ZLD) of aniline ...

Osmotic Membrane Distillation Crystallization of NaHCO3

open access: yesEnergies, 2022
A new crystallization process for sodium bicarbonate (NaHCO3) was studied, proposing the use of osmotic membrane distillation crystallization. Crystallization takes place due to the saturation of the feed solution after water evaporation on the feed side,

Crystallization of membrane proteins

open access: yesCurrent Opinion in Structural Biology, 1997
Five new membrane protein structures have been determined since 1995 using X-ray crystallography: bacterial light-harvesting complex; bacterial and mitochondrial cytochrome c oxidases; mitochondrial bc1 complex; and alpha-hemolysin. These successes are partly based on advances in the crystallization procedures for integral membrane proteins.
