Abstract

original image

Carbon nanotubes: The end section of a carbon nanotube, cut by acid treatment, contains hydrophilic oxygen groups, around which water molecules can assemble to block the entry of the tube. Hydrogen of pressures up to 10 000 bar can be locked inside the tube by such an “aqueous valve” (see picture).
