Graphene nanoplatelets make good metal-free catalysts

Metal-free carbon-based electrocatalysts for dye-sensitized solar cells (DSSCs) are active enough in one type of commonly used (cobalt-based) electrolyte but not in another (iodide-based) one. Now, researchers at UNIST in Korea say they may have overcome this problem with their new catalyst made from edge-selenated graphene nanoplatelets, which has a high power conversion efficiency (PCE) […]

Correlation force spectroscopy reveals tethering effects on DNA

The replication of DNA involves conformational changes are that are greatly affected by its mechanical properties. Tethering DNA has profound effects on its mechanical properties, but there are few studies that attempt to quantify this change. Researchers at Virginia Tech have developed and refined a technique that allows high-sensitivity force measurements of dynamic systems, and […]
