NASA's Glenn Research Center has developed a novel solid oxide fuel cell (SOFC) with five times the specific power density of currently available SOFCs. This highly efficient SOFC can operate on a...

Gyroscopes are devices that help vehicles, drones, and wearable and handheld electronic devices know their orientation in three-dimensional space. Originally, gyroscopes were sets of nested wheels, each spinning...

Many of today's silicon-based electronic components contain 2D materials such as graphene. Incorporating 2D materials like graphene — which is composed of a single-atom-thick layer of carbon atoms...

Heat treatment, also known as annealing, is a common step in the semiconductor fabrication process. A buildup of radiation-induced localized charge within the...

Gas turbine blades of conventional rotorcraft turboshaft engines are optimized to operate at nearly a fixed speed and a fixed incidence angle. If the operating condition of the engine changes, then the flow...

The first laser based on the wave physics phenomenon called bound states in the continuum (BIC) has been developed. The technology could revolutionize the development of surface...

Cellphones, laptops, tablets, and many other electronics rely on their internal metallic circuits to process information at high speed. Current metal fabrication techniques...

Colloids — insoluble particles or molecules anywhere from a billionth to a millionth of a meter across — are so small they can stay suspended indefinitely in a liquid or even in air. Robots about...

Quantum computers will be able to solve problems well beyond the reach of existing computers while working much faster and consuming vastly less energy. An inorganic compound was developed that...

Current density is the amount of electrical current per cross-sectional area at a given point. As transistors in integrated circuits become smaller and smaller, they need higher and higher...

One current method to build a semiconductor superlattice — materials comprised of alternating layers of ultra-thin, two-dimensional sheets only one or a...

Most metals, with the notable exception of gold, tend to oxidize when exposed to air and water. This reaction — which produces rust on iron, tarnish on silver, and verdigris on copper or...

Eagles can store energy in their feet without having to continuously contract their muscles to then jump high or hold on to prey. New materials have been created that can store energy this way. The...

An advanced, highly compact thermal camera that traces its heritage to one now flying on NASA's Landsat 8 has been mounted in a corner of NASA's...

Additive manufacturing (3D printing) can be used to manufacture porous electrodes for lithium-ion batteries, but because of the nature of the manufacturing process, the design of these...

The exhaust heat recovery system (EHRS) in an automobile captures the thermal energy from exhaust and transfers it to the engine coolant. As the car warms up,...

Photons, or units of light, are faster than electrons and could, therefore, process information faster from smaller chip structures. A switch was designed that bypasses a...

Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened...

Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...

By stacking and connecting layers of stretchable circuits on top of one another, soft, pliable 3D stretchable electronics were fabricated that can pack a lot of functions while staying thin and small...

A process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue lays the foundation for soft active matter with highly...
