Fluoropolymer Membranes for Membrane Distillation and Membrane Crystallization

open access: yesPolymers, 2022
Fluoropolymer membranes are applied in membrane operations such as membrane distillation and membrane crystallization where hydrophobic porous membranes act as a physical barrier separating two phases. Due to their hydrophobic nature, only gaseous molecules are allowed to pass through the membrane and are collected on the permeate side, while the ...

Membrane Systems with Marked Membranes [PDF]

open access: yesElectronic Notes in Theoretical Computer Science, 2007
Membrane computing is a biologically inspired computational paradigm. Motivated by brane calculi we investigate membrane systems which differ from conventional membrane systems by the following features: (1) biomolecules (proteins) can move through the regions of the systems, and can attach onto (and de-attach from) membranes, and (2 ...

Study on the Preparation of Cellulose Acetate Separation Membrane and New Adjusting Method of Pore Size

open access: yesMembranes, 2021
As a kind of eco-friendly (biodegradable) material and with a natural anti-fouling ability, cellulose acetate (CA) is more suitable for single-use membrane (especially in bioprocess).

The microbiologist’s guide to membrane potential dynamics [PDF]

open access: yes, 2020
All cellular membranes have the functionality of generating and maintaining the gradients of electrical and electrochemical potentials. Such potentials were generally thought to be an essential but homeostatic contributor to complex bacterial behaviors ...

Investigating the Effects of Nonsolvent Additive and Spinning Conditions on Morphology and Permeation of PAN Hollow Fiber Membranes

open access: yesAdvances in Polymer Technology, 2022
In this study, polyacrylonitrile hollow fiber (PAN HF) membranes were designed and fabricated with desired morphology and permeability for low pressure-driven applications via the dry-wet phase-inversion spinning process.

Is It Possible to Prepare a “Super” Anion-Exchange Membrane by a Polypyrrole-Based Modification?

open access: yesMembranes, 2023
In spite of wide variety of commercial ion-exchange membranes, their characteristics, in particular, electrical conductivity and counterion permselectivity, are unsatisfactory for some applications, such as electrolyte solution concentration.

TECPR1 promotes aggrephagy by direct recruitment of LC3C autophagosomes to lysosomes

open access: yesNature Communications, 2020
Many neurodegenerative disorders are characterised by the accumulation of protein aggregates in neurons. Here, the authors show that the lysosomal protein TECPR1 selectively recruits mature autophagosomes via an interaction with LC3C to break down ...

A quantitative description of membrane current and its application to conduction and excitation in nerve

open access: yesJournal of Physiology, 1952
This article concludes a series of papers concerned with the flow of electric current through the surface membrane of a giant nerve fibre (Hodgkinet al., 1952,J. Physiol.116, 424–448; Hodgkin and Huxley, 1952,J. Physiol.116, 449–566).

Membranous laryngotracheobronchitis (membranous croup) [PDF]

open access: yesAmerican Journal of Roentgenology, 1979
Membranous laryngotracheobronchitis (membranous croup), not previously described as a distinct entity, is characterized by diffuse inflammation of the larynx, trachea, and bronchi with adherent or semiadherent mucopurulent membranes in the subglottic trachea (conus elasticus) and in the upper trachea distal to the conus elasticus.

Changes in membrane lipids drive increased endocytosis following Fas ligation [PDF]

open access: yes, 2017
Once activated, some surface receptors promote membrane movements that open new portals of endocytosis, in part to facilitate the internalization of their activated complexes.
