Changes in slope of Arrhenius plots for transport can, in some instances, be detected at two different temperatures for cells that have a relatively simple fatty-acid composition in the membrane lipids. These characteristic temperatures correlate with the characteristic temperatures that define changes of state in membrane phospholipids as revealed by the paramagnetic resonance of the spin labe...

The present work focuses on the anti-neoplastic role of non steroidal anti-inflammatory drugs (NSAIDs) in modulating the biophysical parameters of the colonic membranes in 1,2-dimethylhydrazine dihydrochloride (DMH) induced carcinogenesis. The steady-state fluorescence polarization technique was applied to assess membrane fluidity, membrane polarity and lipid phase states. The decline in choles...

Dyes are an essential group of organic pollutants with a long history harming aquatic life and humans. Prior to disposal, polluted dye wastewater must be adequately treated prevent adverse impacts on persons the environment. Although there several techniques for removal, most them share similar drawback: they generate secondary pollution Membrane separation is highlighted in this article becaus...

Paramagnetic resonance spectra of spin labels partitioned into spheroplast membranes of Bacillus stearothermophilus indicate lateral lipid phase separations. Cells adjust their lipid composition in response to temperature changes so that the same change of state in membrane phospholipids is achieved at the respective growth temperature. A temperature-sensitive mutant that fails to change its li...

Chemical separations play an important role in most chemical, pharmaceutical, and petrochemical processes. Membrane-based separations are potentially important because they can be less energy intensive and more economical than conventional separation methods [1]. By controlling the pore diameter of track-etched nanoporous polymer membranes, they can be used as nanofilters for the separation of ...

The intrinsic defects in reduced graphene oxide (rGO) formed during reduction processes can act as nanopores, making rGO a promising ultrathin-film membrane candidate for separations. To assess the potential of rGO for such applications, molecular dynamics techniques are employed to understand the defect formation in rGO and their separation performance in water desalination and natural gas pur...
