How to grow nanostructures in a controlled manner
Post# of 22456
Materials scientist Irem Tanyeli from energy research institute DIFFER has discovered how you can grow nanostructures in a controlled manner on a variety of metals, by bombarding the metals with helium particles. Such controlled nanostructures provide the possibility of advanced electrodes that produce sustainable fuel using solar energy.
