Particle size is more important than previously believed when it comes to nanocrystal phase transformations. This is the new finding from researchers at the Lawrence Berkeley National Laboratory in California and the University of California at Berkeley. The result could be important for designing future hydrogen storage systems, catalysts, fuel cells and batteries from these nanostructures…………….
