Beautiful 'flowers' self-assemble in a beaker

By simply manipulating chemical gradients in a beaker of fluid, materials scientists at Harvard have found that they can control the growth behavior of crystals to create precisely tailored structures—such as delicate, ...

A material that most liquids won't wet

(Phys.org)—A nanoscale coating that's at least 95 percent air repels the broadest range of liquids of any material in its class, causing them to bounce off the treated surface, according to the University of Michigan engineering ...

Photonic gels are colorful sensors

(Phys.org)—Materials scientists at Rice University and the Massachusetts Institute of Technology (MIT) have created very thin color-changing films that may serve as part of inexpensive sensors for food spoilage or security, ...
