Clues found in nanoparticles may help produce environmentally clean energy.
Nanoscale metal particles naturally have a wide variety of shapes and sizes and chemists long suspected that some particles work much better than others when it comes to catalyzing chemical processes. Researchers at Cornell University recently confirmed the hypothesis and discovered that some nanoparticles randomly change from good particles to bad particles.
