Novel crumpling method takes flat graphene from 2-D to 3-D

Researchers have developed a unique single-step process to achieve three-dimensional (3D) texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3D texturing, or 'crumpling', allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.

Improving energy efficiency one atom at a time

Molecular beam epitaxy systems enables scientists to control the properties of new crystals with exquisite precision, right down to the atomic level. They can grow nanomaterials with features just a few billionths of a meter across, and even control how many electrons they have inside them.

Researchers synthesize material for efficient plasmonic devices in mid-infrared range

A research team has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared range. This is the first time anyone has demonstrated a material that performs efficiently in response to this light range, and it has applications in fields ranging from high-speed computers, to solar energy to biomedical devices.
