Battery degradation
Yuliya Preger tests batteries in her lab to understand how their performance degrades under different conditions. Yuliya was recognized by DOE’s Women @ Energy: STEM Rising website, which honors women in STEM fields throughout the DOE complex. Learn more at bit.ly/3IDWAw3 Photo by Bret Latter
Renewable energy and mentoring leader
Sandra has been a Sandia National Laboratories engineer working primarily on renewable energy development for 29 years, many of them dedicated to positively impacting U.S. tribes. Nearly two decades ago, Sandra began providing technical assistance to the Navajo Tribal Utility Authority, which received federal funding to begin a program focused on a photovoltaic solar electric system for residential customers who were not connected to the electrical grid. With federal sponsorship, she was able to provide technical assistance to more than 15 U.S. tribes for 16 years. She was recognized with a 2021 Women in Technology Award from the New Mexico Technology Council and a 2020 Indigenous Excellence Award from the American Indian Science and Engineering Society.

Lifelong curiosity and looking up
Sandia Deputy Labs Director Laura McGill began her career at the General Dynamics aerodynamic test facility in San Diego, which later became Lockheed Martin, where she blended her passions for engineering and aviation. She was directly involved in early F-22 wind tunnel testing and is pictured in front of an F-22 model. Learn more at bit.ly/3v9dMGI Photo by Randy Montoya
Rare open-access quantum computer
Sandia National Laboratories physicist Susan Clark leads the team that built the Quantum Scientific Computing Open User Testbed. The ion-based quantum computer was made for outside researchers to use. Learn more at bit.ly/35aR46y Photo by Bret Latter
Safety matters
Cynthia Rivera is one of 38 National Safety Council’s honorees under age 40 with a proven track record of workplace safety leadership and dedication to continuous improvement. Learn more at bit.ly/3qB6sk4 Photo by Bret Latter
Gate set tomography
Sandia National Laboratories researchers Andrew Baczewski, left, and Erik Nielsen use a Sandia technique called gate set tomography to analyze problems in a quantum processor. Two papers published in the scientific journal Nature describe how separate research teams — one including Sandia researchers — used gate set tomography to develop and validate highly reliable quantum processors. Sandia has been developing gate set tomography since 2012, with funding from the DOE Office of Science through the Advanced Scientific Computing Research program.

Material Data Driven Design
Sandia National Laboratories researchers David Montes de Oca Zapiain, left, and Hojun Lim examine data generated by the machine learning algorithm Material Data Driven Design that could provide auto manufacturing, aerospace and other industries a faster and more cost-efficient way to test bulk materials.

Improved nuclear accident code
Jenn Leute, left, and Dan Clayton, two Sandia National Laboratories nuclear engineers, stroll outside of a nuclear facility. Recently they updated a consequence assessment code, Maccs, so that it can model the health and economic impacts of an unlikely accident practically to a facility’s fence.

Safer, more powerful batteries
Alex Bates, front, and John Hewson, Sandia National Laboratories engineers, examine a lithium-ion battery in front of a specially designed battery testing chamber. They compared the heat released by a traditional lithium-ion battery to the heat released by a solid-state battery and a solid-state battery with a little liquid electrolyte. They found in many cases solid-state batteries with a little liquid electrolyte were safer than their lithium-ion counterparts. Learn more at bit.ly/3hONSQW Photo by Rebecca Gustaf
Record-breaking, ultrafast device to protect the grid
Luke Yates, left, a Sandia National Laboratories electrical engineer, passes Jack Flicker, a grid resiliency expert, a gallium nitride wafer with an array of diodes that can shunt a record-breaking 6,400 volts of electricity within a few billionths of a second – a significant step towards protecting the nation’s electric grid from an electromagnetic pulse.

Pandemic countermeasures
Sandia National Laboratories researchers Jennifer Schwedler, left, and Yooli Kim Light advance the creation of a wide array of disease-fighting tools, including nanobody therapies. Learn more at bit.ly/3EX4Fv1 Photo by Randy Wong
Biodefense and countering disease
Christine Thatcher, left, and Peter McIlroy are members of the nanobody research team at Sandia National Laboratories. With a rich history of biodefense research, Sandia helps protect the nation and the world from threats presented by bioterrorism and naturally occurring diseases.

Fog facility
Andres Sanchez, left, Jeremy Wright, center, and Brian Bentz prepare for an optical test in Sandia National Laboratories’ fog facility. Bentz is leading a three-year project to use computational imaging to detect, locate and image objects in fog. Learn more at bit.ly/30CG6Va Photo by Randy Montoya
Optical sensors to see through fog
Sandia National Laboratories’ researchers stand inside the fog facility after setting up for an experiment. They are conducting new optical research in computational imaging and partnering with NASA researchers, Teledyne FLIR and others to test sensors in customized fog that can be measured and repeatedly produced on demand.

Remote high-voltage sensor
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. Learn more at bit.ly/3ktbdZW Photo by Bret Latter
Migrating south
Mark Ivey, left, a Sandia National Laboratories senior engineer, and Fred Helsel, a systems engineer, inspect a shelter that had been stationed in Oliktok Point, Alaska. After eight great years of observations and research, a Sandia-operated Atmospheric Radiation Measurement mobile facility moved from Oliktok Point and will be relocating to the southeastern United States.

Hot salt
Melissa Mills, left, a Sandia National Laboratories geochemist, and Kristopher Kuhlman a Sandia geoscientist, display salt samples from their Waste Isolation Pilot Plant experimental site. They have just begun the third phase of a yearslong basic science experiment to understand how salt and very salty water behave near hot nuclear waste containers in a salt-bed repository.
