laboratoryequipment: Nano-raspberries May Bear Fueling FruitResearchers 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.”The research could help make fuel cells more practical. Nanoparticles can act as catalysts to help convert methanol to electricity in fuel cells. NIST’s 40-minute process for making nano-raspberries, described in a new paper, has several advantages. The high surface area of the berries encourages efficient reactions. In addition, the NIST process uses water, a benign or “green” solvent. And the bunches catalyze methanol reactions consistently and are stable at room temperature for at least eight weeks.Read more: http://www.laboratoryequipment.com/news/2015/06/nano-raspberries-may-bear-fueling-fruit -- source link
