From alum Walter Drisdell's lab at LBL: new research published in the journal ACS Catalysis exams experiments performed vis X-ray spectroscopy on working solar fuel generator prototypes to demonstrate that catalysts made from copper oxide are superior to purely metallic-origin catalysts when it comes to producing ethylene, a two-carbon gas with a huge range of industrial applications – even after there are no detectable oxygen atoms left in the catalyst.
BERKELEY, Calif. (KGO) -- A single image helped alert the world to a once-in-a-lifetime side effect of the COVID-19 crisis. It was a satellite map, showing a dramatic drop in pollution levels over China after the country began to effectively quarantine its population. Shortly afterward Ron Cohen, Professor of Chemistry and of Earth and Planetary Sciences at UC Berkeley, predicted a similar effect here in the Bay Area.
Fewer vehicles on the road and the slowing world economy has lead to blue skies over the world including the Bay Area, China, and Italy. Locally, every day since March 14, the EPA Air Quality Index has reported all nine Bay Area counties bathed in green on its color scale, for good quality air. It’s rare to have so many consecutive clean-air days. And last week, air-quality sensors that measure particulate matter showed the lowest average readings of any week so far in 2020 — down 21% in Oakland, 36% in San Jose and 41% in San Francisco from the week before.
Scientists who scanned the skies above dozens of U.S. cities have made a surprising discovery about the smog that’s suspended over Los Angeles: one of its key ingredients isn’t disappearing as fast as it once did. The finding may help explain why the once-steady improvements in air quality have come close to stalling out here even though nitrogen oxide emissions have continued to decline. It also suggests that the particular chemistry of L.A.'s air may complicate future cleanup efforts. “That’s certainly part of why we’re in a moment in Los Angeles where it’s harder to get the air cleaner,” said Professor Ronald Cohen.
The International Union of Pure and Applied Chemistry (IUPAC) has released the results of its first search for the Top Ten Emerging Technologies in Chemistry. Initiated as a special activity in honor of IUPAC’s 100th anniversary this year, the results have been published in the 2019 April-June 2019 issue of Chemistry International. Research from the lab of Omar Yaghi on water harvesting from desert air technology has been featured as one of the top 10.
A newly developed sorbent-based alternative has recently shown that it can harvest atmospheric moisture even when the relative humidity drops to around 10 percent. Under those conditions, that works out to around three liters of water for every million...
