Berkeley Lab materials scientist Peidong Yang has been named one of 24 new MacArthur Fellows in the class of 2015. Yang was cited for “opening new horizons for tackling the global challenge of clean, renewable energy sources through transformative advances in the science of semiconductor nanowires and nanowire photonics.”
Berkeley Lab researchers have produced the first atomically thin 2D sheets of organic-inorganic hybrid perovskites. These ionic materials exhibit optical properties not found in 2D covalent semiconductors such as graphene, making them promising alternatives to silicon for future electronic devices.
Berkeley researchers have devised an ultra-thin invisibility “skin” cloak that can conform to the shape of an object and conceal it from detection with visible light. Although this cloak is only microscopic in size, the principles behind the technology should enable it to be scaled-up to conceal macroscopic items as well.
Scientists have been scanning the sky with methods that haven’t changed much until the last two decades. Now a Berkeley Lab-based collaboration of astrophysicists, statisticians and computer scientists has created a new model, designed to enhance one of modern astronomy’s most time-tested tools: sky surveys.
Berkeley Lab’s particle accelerator blasts microprocessors with high-energy beams to toughen them up for trips into low-earth orbit and beyond. It’s a radiation-testing process that finds a chip’s weak spots, highlighting when, where, and how engineers need to make the microprocessor tougher.
Berkeley Lab researcher Evan Mills has co-authored an investigation of the aggregate global energy use of personal computers designed for gaming and found that gamers can achieve energy savings of more than 75 percent by changing some settings and swapping out some components, while also improving reliability and performance.
Berkeley Lab scientists have reported a major advance in understanding the biological chemistry of radioactive metals, opening up new avenues of research into strategies for remedial action in the event of possible human exposure to nuclear contaminants.
In the most comprehensive analysis of U.S. electricity reliability trends, researchers at Berkeley Lab and Stanford University have found that while the frequency of power outages has not changed in recent years, the total number of minutes customers are without power each year has been increasing.
