Anchoring individual iridium atoms on the surface of a catalyst made them a lot better at splitting water – a reaction that’s been a bottleneck in making sustainable energy production more competitive.
Drawing on SLAC facilities, Australian researchers have revealed how Streptococcus pneumoniae bacteria obtain manganese from our bodies, which could lead to better therapies to target the pathogen.
Storing the rechargeable batteries at sub-freezing temperatures can crack the battery cathode and separate it from other parts of the battery, a new study shows.
Researchers have made the first direct observation of how hydrogen atoms in water molecules tug and push neighboring water molecules when they are excited with laser light.
Naked RNA molecules are too floppy for high-res 3D imaging, but a system developed at SLAC and Stanford fixes that. It reveals detailed RNA structures from a pond scum critter and COVID-19 virus.
Scientists at Stanford and SLAC made a new catalyst that works with either heat or electricity to accelerate a reaction for turning carbon dioxide into carbon monoxide. It's an important step toward unifying the understanding of catalytic reactions in these two very different conditions.
Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have demonstrated that they can use machine learning to optimize the performance of particle accelerators by teaching the algorithms the basic physics principles behind accelerator operations – no prior data needed.
The agreement, announced today, will make it easier for researchers to change their names and claim work from all stages of their careers. It specifically addresses the administrative and emotional difficulties some transgender researchers have experienced when requesting such name changes.
Scientist demonstrated a new way of observing atoms as they move in a tiny quantum electronic switch as it operates. Along the way, they discovered a new material state that could pave the way for faster, more energy-efficient computing.
Highlights of the two-hour visit included behind-the-scenes looks at one of the most powerful X-ray sources on the planet and at the construction of the world’s largest digital camera for astronomy. She also joined presentations of the lab’s research in machine learning, quantum technology and climate science and engaged in discussions about diversity, equity and inclusion at SLAC.
Are new nickelate superconductors close kin to the original high-temperature superconductors, the cuprates? The first study of their magnetic properties says the answer is yes. Scientists from SLAC, Stanford and Diamond Light Source found important similarities but also subtle differences between the two.
Petroglyphs are carved in a material called rock varnish, the origins of which have been debated for years. Now, scientists argue it’s the result of bacteria and an adaptation that protects them from the desert sun’s harsh rays.
SLAC and Stanford scientists took a unique and detailed nanoscale look at how oxygen seeps out of lithium-ion battery electrodes, sapping their energy over time. The results could suggest a fix.
Among the many scientists who push the frontiers of knowledge at the Department of Energy’s SLAC National Accelerator Laboratory, the Panofsky fellows stand out.
Transitioning to a hydrogen economy will require massive production of cheap, clean hydrogen gas for fuel and chemical feedstocks. New tools allow scientists to zoom in on a catalytic reaction that’s been a bottleneck in efforts to generate hydrogen from water more efficiently.
When light hits certain molecules, it dislodges electrons and creates areas of positive and negative charge. An X-ray free-electron laser study has directly observed how this charge transfer affects a molecule's structure for the first time.
Although many organisms capture and respond to sunlight, enzymes – proteins that catalyze biochemical reactions – are rarely driven by light. A new study captures the full cycle of complex structural changes in an light-driven enzyme called FAP as it transforms a fatty acid into alkanes or alkenes.
High-temperature superconductors conduct electricity with no loss, but no one knows how they do it. SLAC scientists observed the signature of an exotic state of matter called “pair density waves” in a cuprate superconductor and confirmed that it intertwines with another exotic state.
Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots’ light-producing efficiency. A new study explains why, and the results have broad implications for developing future quantum and photonics technologies where light replaces electrons in computers and fluids in refrigerators, for example.
For the past few years, researchers at the Department of Energy’s SLAC National Accelerator Laboratory have been developing “virtual diagnostics” that use machine learning to obtain crucial information about electron beam quality in an efficient, non-invasive way. Now, a new virtual diagnostic approach incorporates additional information about the beam that allows the method to work in situations where conventional diagnostics have failed.
