Polymer membranes that "simultaneously and surprisingly" improve permeability while favoring bigger molecules over smaller ones have been developed by a team of researchers that includes Dr. Richard J ...

Bacteria and yeast need to prevent leakage of numerous small molecules through their cell membrane. Biochemists have studied how the composition of the membrane affects passive diffusion and the ...

Smart materials are revolutionizing water purification with adaptive membranes and nanostructures, enhancing efficiency and sustainability in treatment systems.

How does Membrane Inlet Mass Spectrometry Work? Membrane Inlet Mass Spectrometry (MIMS) relies on the principles of mass spectrometry and the selective permeability of membranes that allow the passage ...

Scientists have developed a computational method based on large-scale molecular dynamics simulations to predict the cell-membrane permeability of cyclic peptides using a supercomputer. Their protocol ...

Bacteria, fungi, and yeast are very good at excreting useful substances such as weak acids. One way in which they do this is through passive diffusion of molecules across the cell membrane. At the ...
