Graphene isn’t the only Lego in the materials-science toy box

Graphene isn’t the only Lego in the materials-science toy box

You may have heard of graphene, a sheet of pure carbon, one atom thick, that’s all the rage in materials-science circles, and getting plenty of media hype as well. Reports have trumpeted graphene as an ultra-thin, super-strong, super-conductive, super-flexible material. You could be excused for thinking it might even save all of humanity from certain doom.

The Future of Medicine Could Be Found in This Tiny Crystal Ball

The Future of Medicine Could Be Found in This Tiny Crystal Ball

A Drexel University materials scientist has discovered a way to grow a crystal ball in a lab. Not the kind that soothsayers use to predict the future, but a microscopic version that could be used to encapsulate medication in a way that would allow it to deliver its curative payload more effectively inside the body.

Single Molecule Detection of Contaminants, Explosives or Diseases Now Possible

Single Molecule Detection of Contaminants, Explosives or Diseases Now Possible

A technique to combine the ultrasensitivity of surface enhanced Raman scattering (SERS) with a slippery surface invented by Penn State researchers will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.
