Filtration of micropolar liquid through a membrane composed of spherical cells with porous layer [PDF]
, 2019 This paper considers membranes of globular structure in the framework of the cell model technique. Coupled micropolar and Brinkman-type equations are used to model the flow of micropolar fluid through a spherical cell, consisting of solid core, porous layer and liquid envelope. The solution is obtained in analytical form.

Measuring Oxygen, Carbon Monoxide and Hydrogen Sulfide Diffusion Coefficient and Solubility in Nafion Membranes [PDF]
Electrochimica Acta, 54(27), 6850-6860, 2009, 2011 A Devanathan-Stachurski type diffusion cell made from a fuel cell assembly is designed to evaluate the gas transport properties of a proton exchange membrane as a function of cell temperature and gas pressure. Data obtained on this cell using the electrochemical monitoring technique (EMT) is used to estimate solubility and diffusion coefficient of ...

Blue Light Enhances Fluoride Anticariogenic Activity against Streptococcus mutans
Biophysica, 2022 Previous studies have shown that sub-lethal exposure of blue light caused increased bacterial cell membrane permeability. We hypothesized that combining blue light exposure with other antibacterial agents may increase their efficacy.

A Barrier to Entry: Examining the Bacterial Outer Membrane and Antibiotic Resistance
Applied Sciences, 2023 Gram-negative bacteria can resist antibiotics by changing the permeability via their outer membrane. These bacteria have a complex cell envelope that incorporates an outer membrane separating the periplasm from the external environment.

Melting transitions in biomembranes [PDF]
BBA - Biomembranes 1861 (2019) 183026, 2019 We investigated melting transitions in biological membranes in their native state that include their membrane proteins. These membranes originated from \textit{E. coli}, \textit{B. subtilis}, lung surfactant and nerve tissue from the spinal cord of several mammals.
