Researchers at the University of Pennsylvania have shown how a fuel cell can be built with monodisperse platinum-cobalt nanocrystals – a scientific advance that could pave the way for making fuel cell technology more stable and cost-effective.
Researchers at Penn State have developed a field-effect transistor that is made of 2D materials and that is more energy efficient and produces less heat than field-effect transistors used in current computers. This new transistor is inspired by how the brain works and provides a range of probabilistic responses instead of “on” or “off” responses.

A chameleon can alter the color of its skin by using periodic optical nanostructures, called photonic crystals, in its skin. So far, scientists have made versions of a photonic crystal "smart skin" that changes color in response to the environment, but the sizes of these versions of “smart skin” also change. This time, chemists at Emory University have developed a flexible smart skin that reacts to heat and sunlight while maintaining a near constant volume.

A Northwestern University research team has developed a new method for making catalysts from metal nanoparticles that could lead to better fuel cells. The researchers also discovered that the method can take spent catalysts and recycle them into active catalysts.

Scientists from Caltech, Georgia Tech, and the Swiss Federal Institute of Technology (ETH) in Zurich have developed a metamaterial that can change shape in a tunable fashion. While most reconfigurable materials can toggle between two distinct states – the way a switch toggles on or off – the new material's shape can be finely tuned, adjusting its physical properties as desired. The material has potential applications in next-generation energy storage and bio-implantable micro-devices.

The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has awarded a total of nearly $4 million in grants to 19 small businesses to support innovative technology development. Five of the 19 small businesses (Graphene Waves LLC, Parman Tech LLC, Xallent LLC, Advanced Silicon Group, and Applied NanoFluorescence) were awarded nearly $1.1 million awarded for nanotechnology development.
