To approach the subject of osmotic pressure against an ideal impermeable membrane by the easiest way, consider first a vessel filled with any particular fluid divided into two parts, A and B, by an ...

Dialysis effects the simple, gentle, and gradual separation of biological and other molecules from unwanted molecules in solution by selective diffusion through a semipermeable membrane. In practice, ...

A look directly at the cell membrane is changing our understanding of its organization. Using a completely new approach to imaging cell membranes, a new study has revealed surprising relationships ...

A study published in ACS Energy Letters reveals that researchers have developed a semipermeable membrane capable of harnessing this osmotic energy from salt gradients to generate electricity. In ...

A new study conducted at MIT has examined the potential of pressure-retarded osmosis (PRO), a technique that generates electricity from the difference in salinity between two pools of water separated ...

Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists has demonstrated an energy-efficient desalination technology that ...

Membrane associated molecules that are probably glycoproteins could be specifically precipitated from NP-40 detergent solubilized extracts of radiolabeled mouse spleen or lymph node cells by antisera ...

The blood–brain barrier presents a major challenge for drug delivery. However, the lamprey’s immune system could hold its key. The blood–brain barrier (BBB) is a semipermeable membrane that separates ...

Microdialysis probes are useful little tools. They sample molecules in real-time from living tissue, often the brains of rats and mice. But some important regions of those brains are so small, they ...
