New Process Uses Nanoparticles to Control Molecular Growth

Scientists from UCLA have developed a new process that uses nanoparticles to control molecular growth within the “building block” components of inorganic materials. Growth is a ubiquitous phenomenon in plants and animals. But it also occurs naturally in chemicals, metals and other inorganic materials. That fact has, for decades, posed a major challenge for scientists […]
