Exotic metamaterials will change optics

Duke University engineers believe that continued advances in creating ever-more exotic and sophisticated man-made materials will greatly improve their ability to control light at will.

Making a better invisibility cloak

The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ties up one of the ...

Physicists investigate onset of effective mass

(Phys.org) —Although mass may seem to be a fairly straightforward concept, from a physics perspective it can be much more complex than weighing an object and reading off a number in grams. For instance, an object's mass ...

Bio-inspired coating resists liquids

After a rain, the cupped leaf of a pitcher plant becomes a virtually frictionless surface. Sweet-smelling and elegant, the carnivore attracts ants, spiders, and even little frogs. One by one, they slide to their doom.
