ALBUQUERQUE, N.M. — Solid-state batteries, currently used in small electronic devices like smart watches, have the potential to be safer and more powerful than lithium-ion batteries for things such as electric cars and storing energy from solar panels for later use. However, several technical challenges remain before solid-state batteries can become widespread. A Sandia National […]

Sandia engineer elected fellow of two prestigious national societies
ALBUQUERQUE, N.M. — Babu Chalamala, an engineer and manager of Sandia National Laboratories’ energy storage group, was recently elected fellow of two prestigious national societies. On Jan. 26, he became a fellow of the American Association for the Advancement of Science. On Dec. 7, he became a fellow of the National Academy of Inventors. According […]
Improved nuclear accident code helps policymakers assess risks from small reactors
ALBUQUERQUE, N.M. — Sandia National Laboratories recently updated the Maccs code to better aid the Nuclear Regulatory Commission and the global nuclear industry in assessing the consequences of nuclear accidents. The Maccs code can also evaluate the potential health and environmental risks posed by advanced nuclear reactors and small modular nuclear reactors. Small modular reactors […]
Four Sandians recognized by Society of Women Engineers
ALBUQUERQUE, N.M. — This fall, four Sandia National Laboratories employees were recognized by the Society of Women Engineers. Laura Biedermann, Annie Dallman, Erica Douglas and Chris LaFleur were recognized for their professional excellence, leadership and support of women in science, technology, engineering and mathematics, or STEM. The society, also known as SWE, has empowered women […]
Common ‘Core’: Using molecular fragments to detect deadly opioids
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 pain reliever that is 80 […]
Sandia cooks material-storage containers to assess fire safety
ALBUQUERQUE, N.M. — A team at Sandia National Laboratories has completed a series of tests on specially designed stainless-steel containers used by the Department of Energy for storage and transportation of hazardous materials. The engineers, technologists and project managers were surprised to find that the containers did not split open when heated to 2000 degrees […]
Underground tests dig into how heat affects salt-bed repository behavior
ALBUQUERQUE, N.M. — Scientists from Sandia, Los Alamos and Lawrence Berkeley national laboratories have just begun the third phase of a years-long experiment to understand how salt and very salty water behave near hot nuclear waste containers in a salt-bed repository. Salt’s unique physical properties can be used to provide safe disposal of radioactive waste, […]
Mimicking mother nature: New membrane to make fresh water
ALBUQUERQUE, N.M. — Scientists at Sandia National Laboratories and their collaborators have developed a new membrane, whose structure was inspired by a protein from algae, for electrodialysis that could be used to provide fresh water for farming and energy production. The team shared their membrane design in a paper published recently in the scientific journal […]
Sandia uncovers hidden factors that affect solar farms during severe weather
ALBUQUERQUE, N.M. — Sandia National Laboratories researchers combined large sets of real-world solar data and advanced machine learning to study the impacts of severe weather on U.S. solar farms, and sort out what factors affect energy generation. Their results were published earlier this month in the scientific journal Applied Energy. Hurricanes, blizzards, hailstorms and wildfires […]
Extending nuclear power accident code for advanced reactor designs
ALBUQUERQUE, N.M. — Nuclear power is a significant source of steady carbon-neutral electricity, making the design and construction of new and next-generation nuclear reactors critical for achieving the U.S.’s green energy goals. A number of new nuclear reactor designs, such as small modular reactors and non-light water reactors, have been developed over the past 10 […]
Sandia designs better batteries for grid-scale energy storage
ALBUQUERQUE, N.M. — Researchers at Sandia National Laboratories have designed a new class of molten sodium batteries for grid-scale energy storage. The new battery design was shared in a paper published today in the scientific journal Cell Reports Physical Science. Molten sodium batteries have been used for many years to store energy from renewable sources, […]
Sandia-led center to advance understanding of new solar panel technology
ALBUQUERQUE, N.M. — The Department of Energy recently awarded $14 million to form a Sandia National Laboratories-led center to improve the understanding of perovskite-based photovoltaic technologies and determine the best tests to evaluate the new solar panels’ lifetimes. The efficiency of perovskite-based solar cells has reached 25%, approaching the levels of common crystalline silicon-based solar […]
