Lunar microgrid
Sandia National Laboratories electrical engineers Rachid Darbali-Zamora, front, and Lee Raskin test out an algorithm on a hardware-in-the-loop set-up at the Distributed Energy Technologies Laboratory. Rachid and Lee are part of a team working with NASA to design a reliable and resilient microgrid to power a future base camp on the moon. Lean more at Photo by Rebecca Gustaf
Seashell-inspired shield
Sandia National Laboratories researcher Guangping Xu employs a digital optical microscope to examine the unusually hard coatings inspired by seashells that his lab has produced. The aim is better, cheaper protection of instruments and drivers in danger of fast-moving debris flung by Sandia’s Z machine when it fires. The coatings offer many other possibilities as well.

Sugar coatings
Physicist Chad McCoy at Sandia National Laboratories’ Z machine loads sample coatings into holders. The coatings are made up of very thin layers of confectioners’ sugar from the grocers, burnt to a state called carbon black, interspersed between only slightly thicker layers of silica, which is the most common material on Earth, and baked. When Z fires, researchers will observe how well particular coatings protect objects stacked behind them. Learn more at Photo by Bret Latter
Sustainable skies
Sandia National Laboratories recently published research data demonstrating how cycloalkanes, when used in jet fuel, may reduce condensation trail formation and soot emissions as compared to current fuels. Learn more at Photo by Craig Fritz
Preserving the past
Christina Chavez is Sandia National Laboratories’ first full-time archaeologist. She established the Labs’ cultural resources program within the Environment, Safety and Health group. Lean more at Photo by Bret Latter
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 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 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 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 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 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 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. Learn more at Photo by Randy Wong
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 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.
