Water turns out to be the key. After growing the nanotubes, Pint etches them with a mix of hydrogen gas and water vapor, which weakens the chemical bonds between the tubes and the metal catalyst. When stamped, the nanotubes lay down and adhere, via van der Waals, to the new surface, leaving al...
Researchers from North Carolina State University have learned how to consistently create hollow, solid and amorphous nanoparticles of nickel phosphide, which has potential uses in the development of solar cells and as catalysts for removing sulfur from fuel.
