Rice University scientists have developed a simple way to produce conductive, three-dimensional (3D) objects made of graphene foam. The squishy solids look and feel something like a child’s toy but offer new possibilities for energy storage and flexible electronic sensor applications. The technique detailed in advanced materials is an extension of groundbreaking work by the
Microbiologists led by Derek Lovley at the University of Massachusetts Amherst, who is internationally known for having discovered electrically conducting microfilaments or “nanowires” in the bacterium Geobacter, announce in a new paper this month that they have discovered the unexpected structures in many other species, greatly broadening the research field on electrically conducting filaments.

Researchers have now managed to pinpoint what happens when light is absorbed by extremely small nanoclusters of silver atoms. The results may have useful application in the development of biosensors and in imaging. By combining chemistry and nanotechnology, the research community in recent years has developed a kind of extremely small nanoclusters consisting of only
