NIST Team Demonstrates Novel Way to Convert Heat to Electricity

“Researchers at the National Institute of Standards and Technology (NIST) have fabricated a novel device that could dramatically boost the conversion of heat into electricity. If perfected, the technology could help recoup some of the heat energy that is wasted …

By Cracking a Metal 3D-Printing Conundrum, Researchers Propel the Technology Toward Widespread Application

“Researchers have not yet gotten the additive manufacturing, or 3D printing, of metals down to a science completely. Gaps in our understanding of what happens within metal during the process have made results inconsistent. But a new breakthrough could grant …

How Digital Twins Could Protect Manufacturers From Cyberattacks

“Detailed virtual copies of physical objects, called digital twins, are opening doors for better products across automotive, health care, aerospace and other industries. According to a new study, cybersecurity may also fit neatly into the digital twin portfolio. As more …

Artifacts, Begone! NIST Improves Its Flagship Device for Measuring Mass

“For the first time, the NIST-4 Kibble balance directly incorporates a quantum standard for electrical resistance. In a brightly lit subterranean lab at the National Institute of Standards and Technology (NIST) sits a room-sized electromechanical machine called the NIST …

NIST Retires SHA-1 Cryptographic Algorithm

“The venerable cryptographic hash function has vulnerabilities that make its further use inadvisable. The SHA-1 algorithm, one of the first widely used methods of protecting electronic information, has reached the end of its useful life, according to security experts …

Molecules Have an Orientation, and Scientists Have a New Way to Measure It

“In some materials, the molecules line up in a regular, repeating pattern. In others, they all point in random directions. But in many advanced materials used in medicine, computer chip manufacturing and other industries, the molecules arrange themselves in complex …

NIST Finds a Sweet New Way to Print Microchip Patterns on Curvy Surfaces

“NIST scientist Gary Zabow had never intended to use candy in his lab. It was only as a last resort that he had even tried burying microscopic magnetic dots in hardened chunks of sugar — hard candy, basically — and sending these …

NIST’s Grid of Quantum Islands Could Reveal Secrets for Powerful Technologies

“Researchers at the National Institute of Standards and Technology (NIST) have created grids of tiny clumps of atoms known as quantum dots and studied what happens when electrons dive into these archipelagos of atomic islands. Measuring the behavior of electrons …

Entering a New Phase: NIST Technique Simultaneously Locates Multiple Defects on Microchip Circuits

“Defective computer chips are the bane of the semiconductor industry. Even a seemingly minor flaw in a chip packed with billions of electrical connections might cause a critical operation in a computer or other sensitive electronic device to fail. By …

A Machine Learning-Based Solution Could Help Firefighters Circumvent Deadly Backdrafts

“A lack of oxygen can reduce even the most furious flame to smoldering ash. But when fresh air rushes in, say after a firefighter opens a window or door to a room, the blaze may be suddenly and violently resurrected …
