“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 …
“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 …
“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 …
“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 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 …
“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 …
News 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 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 …
“Scientists have long looked to the brain as an inspiration for designing computing systems. Some researchers have recently gone even further by making computer hardware with a brainlike structure. These “neuromorphic chips” have already shown great promise, but they have …
“An algorithm could reduce the effects of long-term drift in fiber Bragg-grating temperature sensors, making them potentially more useful to industry. Photonic thermometers – which measure temperature using light – have been around in optical fiber form for decades. These devices, called …
