Argonne Invents Reusable Sponge That Soaks Up Oil, Could Revolutionize Oil Spill and Diesel Cleanup

Scientists at Argonne have invented a new foam, called Oleo Sponge, that not only easily adsorbs spilled oil from water, but is also reusable and can pull dispersed oil from the entire water column—not just the surface.

Most Complex Nanoparticle Crystal Ever Made by Design

The most complex crystal designed and built from nanoparticles has been reported by researchers at Northwestern University and the University of Michigan. The work demonstrates that some of nature’s most complicated structures can be deliberately assembled if researchers can control the shapes of the particles and the way they connect using DNA. Potential applications of the cage-like structures, called clathrates, include controlling light, capturing pollutants and delivering therapeutics. New types of lenses, lasers and even Star Trek-like cloaking materials are possible.
