Researchers at the National Institute of Standards and Technology (NIST) have developed a fast, simple process for making platinum “nano-raspberries”—microscopic clusters of nanoscale particles of the precious metal. The berry-like shape is significant because it has a high surface area, which is helpful in the design of catalysts. Even better news for industrial chemists: the researchers figured out when and why the berry clusters clump into larger bunches of “nano-grapes.”
