In the first study of its kind, Berkeley Lab researcher Evan Mills co-authored an investigation of the aggregate global energy use of personal computers designed for gaming—including taking direct measurements using industry benchmarking tools—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. This corresponds to a potential estimated savings of $18 billion per year globally by 2020, or 120 terawatt hours (TWh).
Time-lapse imaging can make complicated processes easier to grasp. Berkeley Lab scientists are using a similar approach to study how cells repair DNA damage. Microscopy images are acquired about every thirty minutes over a span of up to two days, and the resulting sequence of images shows ever-changing hotspots inside cells where DNA is under repair.
Berkeley Lab researchers have incorporated molecules of porphyrin CO2 catalysts into the sponge-like crystals of covalent organic frameworks (COFs) to create a molecular system that not only absorbs CO2, but also selectively reduces it to CO, a primary building block for a wide range of chemical products.
Berkeley Lab researchers using a bioinorganic hybrid approach to artificial photosynthesis have combined semiconducting nanowires with select microbes to create a system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.
In the most comprehensive analysis of electricity reliability trends in the United States, researchers at Berkeley Lab and Stanford University have found that, while, on average, 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 over time.
Using physical chemistry methods to look at biology at the nanoscale, a Berkeley Lab researcher has invented a new technology to image single molecules with unprecedented spectral and spatial resolution, thus leading to the first “true-color” super-resolution microscope.
Working at the Molecular Foundry, Berkeley Lab researchers used their “Campanile” nano-optical probe to make some surprising discoveries about molybdenum disulfide, a member of the “transition metal dichalcogenides (TMDCs) semiconductor family whose optoelectronic properties hold great promise for future nanoelectronic and photonic devices.
