Massachusetts Institute of  laptop battery  Technology engineers has been made and environment-friendly energy storage devices nano-particles on the surface of the first images of individual atoms.

As we all know platinum and cobalt nanoparticles can be mixed to fuel cells play a catalytic reaction and its reaction speed is simple to use platinum catalyst for four times. However, no one know the exact IBM battery reason; This is because the nano-particles on the surface of atomic structure and chemical properties know little about.

Now the use of aberration correction scanning transmission electron microscopy (aberration-corrected Scanning Transmission Electron Microscopy), to determine the atomic structure of the catalyst surface.
