Can the US catch up in the green hydrogen economy?
Green Tech Media -
Hydrogen to power fuel cells will also augment battery-powered vehicles in decarbonizing the transportation sector, particularly for vehicles requiring long range and fast refueling times such as long-haul trucks, Jack Brouwer, a professor at the University of California at Irvine and associate director of the National Fuel Cell Research Center (NFCRC), said in a Monday webinar introducing the report.

UCI Advanced Power and Energy Program to research making steel with renewable resources
Technology.org -
The U.S. Department of Energy has awarded UCI’s Advanced Power and Energy Program $5.7 million to lead an effort to develop novel processes for manufacturing steel without greenhouse gas emissions. … The UCI team is led by APEP director Jack Brouwer, professor of mechanical & aerospace engineering …. Along with its partners, the UCI team will demonstrate that its hydrogen production technology is more efficient and produces lower emissions than current technology. Read More
Population distribution can greatly impact COVID-19 spread, study finds
Medical Xpress -
"Social networks aren't smooth and tidy. They're rough and irregular, so diseases like COVID-19 that are transmitted through intensive contact can spread very unevenly," said co-author Carter Butts, UCI professor of sociology. "This results in some communities getting hit much earlier and a lot harder than others, even within the same area. Those different experiences can shape individuals' understanding of infection risk, impact their willingness to take protective actions, and potentially stress healthcare delivery systems in ways that are not captured well by standard epidemiological projections."

The United States has become a disaster area
The Atlantic -
Researchers who study this tangled web of crises call them “cascading disasters”—disasters that trigger other disasters like falling dominoes. As the climate warms, they are becoming increasingly common. Many risk analysts, though, still treat each disaster as a discrete event, according to Amir AghaKouchak at UC Irvine and Farshid Vahedifard at Mississippi State University. Read More

Twitter users were most likely to retweet public health agency tweets that contained practical information on the medical effects of COVID-19, how to mitigate those effects, and the status of the pandemic, according to a study published today in PLOS One. Led by researchers at the State University of New York in Albany and the University of California, Irvine, the study involved analyzing 149,335 tweets from 690 Twitter accounts of public health, emergency management, and elected officials across the United States from Feb 1 to Apr 30.

When do people retweet health agencies' COVID-19 messages?
Medical Xpress -
An analysis of Twitter messages has surfaced certain features of COVID-19-related tweets by public health agencies that were associated with a higher likelihood of the tweets being passed along—"retweeted"—by individual Twitter users. Jeannette Sutton of the University at Albany, New York, and co-investigator Carter T. Butts at the University of California, Irvine, present these findings in the open-access journal PLOS ONE on September 16, 2020. Read More
Coffee-cup-size gadget could hack solar power — study
E&E News - Energywire -
Researchers at the University of California, Irvine, found that solar inverters — which link solar panels to the wider grid — can be shut down or manipulated to potentially disrupt the flow of electricity. They first presented their new study at the virtual USENIX Security 2020 conference earlier this month. Mohammad Al Faruque, a UC Irvine associate professor of electrical engineering and computer science who led the research, said inverters can be hijacked with equipment worth less than $50. Read More
Slippery superfluids push jets to breaking point
Phys.Org -
To update this field for the 21st century, the Thoroddsen group collaborated with researchers at the University of California, Irvine, to build a device capable of reaching temperatures near absolute zero with windows for viewing with high-speed cameras. At these chilly depths, liquid helium can take on a range of different behaviors, including as a frictionless superfluid. Read More
Sandra Tsing Loh recommends watching in PJs with wine
Pasadena Weekly -
In 2005 Sandra Tsing Loh reconnected with the institute when Caltech and KPCC created a podcast for Loh to host “The Loh Down on Science.” The show is co-produced by LDOS Media Lab, Inc. and SCPR (Southern California Public Radio), in association with the University of California, Irvine Science Communications. The actual content is researched, written and edited by students from the UC Irvine School of Physical Sciences, School of Biological Sciences and School of Engineering. The 90-second show … is broadcast five times a week to over 4 million listeners on 150 public radio stations …. Read More
California blackouts trigger debate about electric grid resilience
Marketplace -
“Before the incorporation of all these renewables and other things, you have the load profile, and then you just turn power plants on and off to meet the load profile,” said Brian Tarroja, a researcher in the Advanced Power and Energy Program at the University of California, Irvine. Some blamed California’s adoption of renewable energy for triggering the blackouts, but Tarroja said that’s an oversimplification. The real culprit is a lack of integration of these renewables and the difficulty of getting all that power where it needs to go. Another issue is that there’s no incentive for utilities to update.
