For decades, Nobel Prize-winning chemist Wilhelm Ostwald, has guided the design of new materials including nanoparticles, with his textbook process known as “Ostwald ripening.” According to his theory, small particles dissolve and redeposit onto the surface of large particles, and the large particles continue to grow until all of the small particles have dissolved. But now, new video footage captured by Berkeley Lab scientists reveals for the first time that nanoparticle growth is directed not by difference in size, but by defects. The scientists recently reported their findings in the journal Nature Communications.
