Ionic strength directed self-assembled polyelectrolyte single-bilayer membrane for low-pressure nanofiltration

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 5, Pages 699-708 doi: 10.1007/s11705-021-2093-3

Abstract: Such a simplified polyelectrolyte deposition procedure results in membranes having outstanding separationThese results surpass the ones for conventional multilayered polyelectrolyte membranes.This work encompasses an investigation of ionic strength induced coiling of the polyelectrolyte chainsand emphasizes the interplay between-polyelectrolyte chain configuration and substrate pore profile.

Panyue ZHANG, Tian WAN, Guangming ZHANG

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 5, Pages 753-760 doi: 10.1007/s11783-011-0368-5

Abstract: prevailing method to reduce sludge volume but the process is slow and usually requires addition of polyelectrolyteWeak sonication could substitute expensive polyelectrolyte coagulant for sludge thickening.Combination of weak sonication and polyelectrolyte could further reduce the settling time to 6 h.The final water content of the thickened sludge was not changed after sonication or polyelectrolyte addition

A cytoprotective graphene oxide-polyelectrolytes nanoshell for single-cell encapsulation

Luanying He, Yulin Chang, Junhao Zhu, Ying Bi, Wenlin An, Yiyang Dong, Jia-Hui Liu, Shihui Wang

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 2, Pages 410-420 doi: 10.1007/s11705-020-1950-9

Abstract: Graphene oxide (GO) has been increasingly utilized in the fields of food, biomedicine, environment and other fields because of its benign biocompatible. We encapsulated two kinds of GO with different sizes on yeast cells with the assistance of polyelectrolytes poly (styrene sulfonic acid) sodium salt (PSS) and polyglutamic acid (PGA) (termed as Y@GO). The result does not show a significant difference between the properties of the two types of Y@GO (namely Y@GO1 and Y@GO2). The encapsulation layers are optimized as Yeast/PGA/PSS/PGA/GO/PGA/PSS based on the morphology, dispersity, colony-forming unit, and zeta potential. The encapsulation of GO increases the roughness of the yeast. It is proved that the Y@GO increases the survival time and enhance the activity of yeast cells. The GO shell improves the resistance of yeast cells against pH and salt stresses and extends the storage time of yeast cells.
