Researchers Sandia National Laboratories have developed a nanoantenna-enabled detector that can boost the signal of a thermal infrared camera by up to three times and improve image quality by reducing dark current — a major component of image noise — by 10 to 100 times. A nanoantenna is a nanoscale antenna-like structure that sends and transmits electromagnetic waves.

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.
