Undercooled metal technology was developed that features liquid metal (in this case, Field's metal, an alloy of bismuth, indium, and tin) trapped below its melting point in polished,...

To investigate oceans, researchers aim to build a submerged network of interconnected sensors that sends data to the surface. Supplying constant power to scores of sensors designed to stay for long...

Contact lenses that can monitor the wearer’s health and correct eyesight use embedded electronics. These, and other curved devices such as solar cells and electronics, could be...

NASA Langley Research Center developed a wind event warning technology that provides a practical early warning system (5-10 minutes) for a severe change in the wind vector. Events such as gusts, shear, microbursts,...

Researchers have created a motion-powered, fireproof sensor that can track the movements of firefighters, steelworkers, miners, and others who work in high-risk environments where they cannot always be seen....

A process was developed for producing oxide perovskite crystals in flexible, free-standing layers. A two-dimensional rendition of this substance is intriguing because 2D materials have been shown to...

A new device, inspired by a rose, inexpensively collects and purifies water. The device is a new approach to solar steaming for water production — a technique that uses energy from sunlight...

A new wireless transceiver was developed that boosts radio frequencies into 100-gigahertz territory, which is quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications...

Very thin nylon films were created that can be used in electronic memory components. The films are several hundreds of times thinner than a human hair and could be used in bendable...

A pocket-sized antenna was developed that could enable mobile communication in situations where conventional radios don’t work such as underwater, through the ground, and over very...

A breakthrough imaging technique developed by Cornell researchers shows promise in decontaminating water by yielding surprising and important information about catalyst particles that can't be...

Certain species of bacteria that exist in oxygen-deprived environments must find a way to breathe that doesn't involve oxygen. These microbes — which can be found deep within mines, at...

Organic semiconductors (OSCs) have emerged as a new class of electronic materials promising a wide range of applications including organic field-effect transistors...

Two very challenging problems facing the U.S. and the world are energy security and global climate change, largely due to dependence on fossil fuels. Cost-effective technologies have been developed that are...

Lithium-air batteries are poised to become the next replacement for currently used lithium-ion batteries that power electric vehicles, cell-phones, and computers....

Today's lithium-ion batteries use cathodes (one of the two electrodes in a battery) made of a transition metal oxide. Batteries with cathodes made of sulfur are considered a...

Researchers have created wearable technology to convert mechanical energy into electrical energy. It presents a step toward the practical realization of self-powered, human-integrated technologies.

Methanol is a key feedstock for the production of chemicals, some of which are used to make products such as plastics, plywood, and paints. Methanol also can fuel vehicles or be reformed to...

NASA Langley Research Center has developed a double-sided Si(Ge)/ Sapphire/III-Nitride hybrid structure. This technology uses both sides of a sapphire wafer to build device...

The color of a material can often tell how it handles heat. With clothing, for example, the darker the pigment, the warmer you're likely to feel on a hot day. Likewise, the more...

Researchers have created technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints that can be used to...

Whereas hydrogen fuel cells (e.g., proton exchange membrane (PEM) and other fuel cells) generate electricity from the chemical reaction between pure hydrogen and oxygen, direct carbon fuel cells...

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 °C and emanates from things like computers, cars, or...

Innovators at NASA’s Glenn Research Center have developed a new means of avoiding and mitigating icing events for aircraft flying above 14,000 feet, dramatically improving aviation...
