Researchers have observed, for the first time, an exotic 3-D racetrack for electrons in ultrathin slices of a tiny crystal they made at Berkeley Lab. The team witnessed a unique behavior in which electrons rotate around one surface, then through the bulk of the material to its opposite surface and back.
Scientists at Berkeley Lab and Cornell University have successfully paired ferroelectric and ferrimagnetic materials so that their alignment can be controlled with a small electric field at near room temperatures. The achievement could open doors to ultra low-power microprocessors, storage devices and next-generation electronics.
Elementary school science teaches us that in the sun, dark colors get hot while white stays cool. Now new research from Berkeley Lab’s Heat Island Group has found an exception: scientists have determined that certain dark pigments can stay just as cool as white by using fluorescence, the re-emission of absorbed light.
Excess light energy that a plant can’t absorb needs to be dissipated to avoid damage and oxidative stress. Berkeley Lab researchers are studying ways to increase the amount of light that can be safely absorbed, potentially leading to more efficient photosynthesis and higher crop productivity.
The DOE award will fund these projects — a nanoparticle-based super insulation, a platform for automated building controls, and an advanced moisture modeling tool — will help meet DOE’s goal to reduce the energy intensity of the U.S. building sector by 30 percent by 2030.
To resolve open questions about plant plumbing — how plants transport water from roots through stems and how they respond to stress such as drought — science teams from around the world met Sept. 1 to 3 at Berkeley Lab and UC Berkeley for an intensive round of experiments using X-rays and other techniques.
Exascale refers to high-performance computing systems capable of at least a billion billion calculations per second, or 50 to 100 times faster than the nation’s most powerful supercomputers. The projects target advanced modeling and simulation solutions to specific challenges supporting key DOE missions.
Catherine “Reba” Siero has worked as an accelerator operator for more than two decades at the Lab’s 88-Inch Cyclotron. Her comfort zone is here in the control room, surrounded by walls bristling with a busy mix of modern and time-tested knobs, dials, buttons, glowing lights, switches and screens. Siero retires next month after 37 years at the Lab.
A new study links the overexpression of 14 genes related to cell division to cancer patients’ prognosis and response to specific treatments. The findings could be used to develop a biomarker used to make more informed decisions about cancer therapy.
Researchers have created a sort of nanoscale display case that enables new atomic-scale views of hard-to-study chemical and biological samples. Their work could help to reveal new structural details for a range of challenging molecules, such as complex chemical compounds and potentially new drugs, by stabilizing them inside metal-organic frameworks (MOFs).
