Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

"These changes make the apical membrane—the top of the cell—less stiff and certain constituents of the tight junctions more mobile, without however affecting the barrier formed by these ...

Membrane-based separations are essential for various processes, such as water filtration and oil and gas separation. The use of graphene and other 2D materials in membrane technology has attracted ...
