Plastics are excellent insulators, meaning they can efficiently trap heat — a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic casings for laptops and mobile phones that overheat, in part, because the...

Newly developed two-dimensional (2D) materials such as graphene — which consists of a single layer of carbon atoms — have the potential to replace traditional microprocessing chips based on silicon, which have reached the limit of how small they can get. But engineers have been...

While silicon carbide (SiC) is an ideal material for building ultraviolet (UV) photodetectors, the absorbed photons get recombined in the first few nanometers at the surface due to a large absorption coefficient in the 200- to 250-nm wavelength band....

Oxygen adversely impacts food flavor and nutrition. NASA’s proposed five-year shelf life for astronaut food requires aggressive measures to minimize oxygen. Previously, NASA packaged foods in containers with a high oxygen and moisture barrier. These materials have limiting properties. They contain a...

Hazardous airborne particles pose a risk for health and safety in a variety of environments; thus, detection of these small particles is essential. Current particle magnification systems are bulky and require a lot of power for operation, making them unsuitable to easily detect and analyze...

A real-time instrument was developed that could scan the atmosphere for toxic agents in order to alert communities to a biological or chemical attack.
