A thin material was developed that can control the redirection and reflection of sound waves with almost perfect efficiency. While many theoretical approaches to...

The Army uses robots that are structurally rigid, making them impractical when performing military operations in highly congested and contested urban environments where covert maneuvering is critical...

Extremely fine porous structures with tiny holes — resembling a kind of sponge at the nano level — can be generated in semiconductors. A method was developed for the controlled manufacture...

Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance...

Researchers have developed an inkjet printing technique that can be used to print optical components such as waveguides. Because the printing approach can also fabricate...

Capturing carbon dioxide (CO₂) and converting it to useful chemicals such as methanol could reduce both pollution and U.S. dependence on petroleum products. Catalysts are used to bring...

Fabrics that resist water are essential for everything from rainwear to military tents, but conventional water-repellent coatings have been shown to persist in the environment and accumulate in our...

The Environmental Protection Agency has listed trinitrotoluene (TNT) as a possible carcinogen, and exposure to the material has been linked to disorders of the blood, such as anemia, and abnormal liver function,...

A next-generation X-ray beamline now operating at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) brings together a unique set of capabilities to measure the...

In the early years of manned flight, wing warping was used for lateral control of an aircraft. This technique consisted of a system of pulleys and cables used to twist the trailing edges of the wings in...

Marine-grade stainless steel is valued for its performance under corrosive environments, and for its high ductility — the ability to bend without breaking under stress. But conventional...

Silver nanowires have drawn significant interest in recent years for use in many applications ranging from prosthetic devices to wearable health sensors due to their flexibility,...
