NMR studies of membrane structure and dynamics [PDF]
, 1978 Over the past decade, there has been considerable interest in the motional state of the phospholipid bilayer membrane. The motivation underlying these efforts has been the contention that the phospholipid bilayer is the basic matrix in which membrane ...

Bang-Bang Control Development of Permeability Changes in a Membrane Model [PDF]
arXiv, 2021 The application of systems and control theory to membrane physiology is presented here. Modeling efforts have focused on describing those physiologically realistic mechanisms which govern the regulation of membrane permeability in nerve. The motivation behind identifying such mechanisms lies in understanding the morphology of neural activity on a ...

Feedback-controlled solute transport through chemo-responsive polymer membranes [PDF]
, 2022 Polymer membranes are typically assumed to be inert and nonresponsive to the flux and density of the permeating particles in transport processes. Here, we study theoretically the consequences of membrane responsiveness and feedback on the steady-state force--flux relations and membrane permeability using a nonlinear-feedback solution-diffusion model of

Forward Osmosis (FO) Membrane Fouling Mitigation during the Concentration of Cows’ Urine
Membranes, 2022 FO membrane fouling mitigation during the concentration of cows’ urine was investigated. In particular, the effects on the permeability recovery of cleaning methods such as membrane washing with deionized (DI) water, osmotic backwash, and chemical ...

Permeability of immobile rings of membrane inclusions to in-plane flow [PDF]
J. Chem. Phys. 150, 154901 (2019), 2018 We study the flow of membranal fluid through a ring of immobile particles mimicking, for example, a fence around a membrane corral. We obtain a simple closed-form expression for the permeability coefficient of the ring as a function of the particles' line fraction.

PERMEABILITY OF MEMBRANES OF DEAD FETUS [PDF]
Obstetrical & Gynecological Survey, 1971 Membranes of dead fetuses showed a three-fold increase in permeability to the haemoglobin molecule when compared with normal and stored membranes. The friability of some of these membranes was markedly increased and their strength and elasticity diminished.

Molecular separation by thermosensitive hydrogelmembranes [PDF]
, 1991 A new method for separation of molecules of different size is presented. The method is a useful addition to conventional separation methods which depend mainly on gel permeation chromatography using size exclusion.
