Gas separation membranes are vital for carbon capture, biogas upgrading, and hydrogen purification, all of which require the separation of carbon dioxide from gases like nitrogen, methane and hydrogen ...

Scientists are now able to "see" a structure that acts as an atomic-size sorter for cells. Without it, many important life functions—nerve signal firing, heartbeat, hormone secretion—could not occur.

Aquaglyceroporin Aqp10, a protein channel for water and glycerol, selectively permeates urea and boric acid due to its unique structural features—report researchers from Japan. By comparing and ...

Researchers reveal how the presence of bulky aromatic amino acids at positions 1 and 3 of the aromatic/arginine selectivity filter determines urea and boric acid permeability in Aquaporin 10 paralogs.
