Theory turns to reality for nonlinear optical metamaterials (w/video)

A research team has realized one of the long-standing theoretical predictions in nonlinear optical metamaterials: creation of a nonlinear material that has opposite refractive indices at the fundamental and harmonic frequencies of light. Such a material, which doesn't exist naturally, had been predicted for nearly a decade.

Transparent, stretchable conductors with a nano-accordion structure design

Researchers have created stretchable, transparent conductors that work because of the structures' 'nano-accordion' design. The conductors could be used in a wide variety of applications, such as flexible electronics, stretchable displays or wearable sensors.
