Common ‘Core’: Using molecular fragments to detect deadly opioids
December 15, 2021 • ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories have developed a method to detect trace amounts of synthetic opioids. They plan to combine their approach with miniaturized sensors to create a hand-portable instrument easily used by law enforcement agents for efficient detection in the field. Fentanyl is a fast-acting, opioid-based...

Remote high-voltage sensor unveiled at Sandia gamma ray lab
November 10, 2021 • ALBUQUERQUE, N.M. — Ever since the first human placed a bare hand on an uninsulated electric line, people have refrained from personally testing energetic materials. Even meters made of metal can melt at high voltages. Now, using a crystal smaller than a dime and a laser smaller than a shoebox,...

Sandia National Laboratories researcher Israel Owens holds the optical sensor used to house the crystal that proved central to his team’s successful attempts to measure very high voltages. The two red spots on each side of the crystal are due to laser light reflecting off the side mirrors used to direct light through the middle of the crystal. The actual experiments used green laser light.

Imaging tool under development exposes concealed detonators — and their charge
July 22, 2021 • ALBUQUERQUE, N.M. — Behold the neutron, the middle child of subatomic particles. At times overshadowed by its electrically charged siblings the proton and the electron, neutrons quietly play important roles in national security. They start nuclear reactions for weapons and power plants. They bombard materials for nuclear safety tests. And...

Students of nuclear security have a problem. Here’s how to help them.
November 12, 2020 • ALBUQUERQUE, N.M. — Radioactive materials are attractive targets to thieves and other bad actors. These are rare finds, valuable on the black market and relatively easy to weaponize. New security professionals rarely learn practical skills for protecting these targets until they are on the job at nuclear power plants, research...

Quantum computing steps further ahead with new projects at Sandia
January 7, 2019 • ALBUQUERQUE, N.M. — Quantum computing is a term that periodically flashes across the media sky like heat lightning in the desert: brilliant, attention-getting and then vanishing from the public’s mind with no apparent aftereffects. Yet a multimillion dollar international effort to build quantum computers is hardly going away. And now,...

Sandia microneedles technique may mean quicker diagnoses of major illnesses
January 2, 2019 • ALBUQUERQUE, N.M. — When people are in the early stages of an undiagnosed disease, immediate tests that lead to treatment are the best first steps. But a blood draw — usually performed by a medical professional armed with an uncomfortably large needle — might not be quickest, least painful or...

Responders provide technical expertise in case of nuclear weapons accidents
November 28, 2018 • ALBUQUERQUE, N.M. — Decades ago, technical experts from the national labs responded in an ad hoc manner to accidents involving nuclear weapons, called “broken arrows.” Thirty-two such accidents have occurred since the 1950s, so the Accident Response Group was created about five decades ago to provide technical expertise in assessing...

Sandia’s international peer mentorship program improves biorisk management
October 24, 2017 • ALBUQUERQUE, N.M. — The world is becoming increasingly interconnected. While this has definite advantages, it also makes it easier to spread disease. Many diseases don’t produce symptoms for days or weeks, far longer than international flight times. For example, Ebola has an incubation period of two to 21 days. Improving...
