Plan to test hydrogen energy at UC Irvine, other spots, stirs controversy

The Orange County Register -
Supporters view a pilot project in the works at UC Irvine as a crucial step in helping California hit its clean energy goals. … UC Irvine could be among the first places in the country, and one of a small number worldwide, where cleaner-burning hydrogen is blended with natural gas and injected into existing pipelines that directly fuel furnaces, water heaters and other gas-powered appliances.

‘Enough is enough!’ Striking UC workers say they are weary but won’t give up

Los Angeles Times -
Jackie Ku, a doctoral student who represents UC Irvine on the UAW 2865 bargaining team, said he is prepared to strike for as long as it takes to secure a fair contract. … As the quarter wound down during finals last week at UC Irvine, the number of picketers on campus thinned slightly. … “It’s exhausting, but if we don’t do it, who else will?” said Tia Wilson, a PhD candidate in material science and engineering at UC Irvine. “I can’t live with the crappy contract, so I’m in it for the long haul.” [Subscription required, you can request an electronic copy of the article by sending an email to communications@uci.edu.] Read More

And a team at the University of California, Irvine, discovered that music could be used to trigger a deadly pathogen release from a negative-pressure room used for biological research. They noted that someone familiar with how pressure controls are used for such rooms could embed a tone in a song playing on a smartphone that would change how the pressure-control fans operate in the room, and thus affect air flow, potentially blowing air out instead of keeping it in.

Why EVs are considered greener

AAA Journey -
“That’s why reuse, purposing and recycling becomes important,” says Iryna Zenyuk, associate professor in chemical and biomolecular engineering at the University of California, Irvine. “Most EV manufacturers provide battery warranty of 8 years or more and about 100,000 miles of driving range. And during this time the battery will lose about 20% of its capacity essentially reaching 80% of its beginning of life capacity.” Rather than replace and discard those batteries, Zenyuk says these lithium-ion batteries still can work very well for stationary applications, where power density is not as demanding, and charging/discharging cycles are slower.

Southern California coastal towns are losing valuable sand, putting some beaches at risk

The Orange County Register -
If solutions aren’t swift, the Southern California coast — and the economy it supports — will surely suffer. “If we have no sand, it’s like a car and we’ve taken the engine out of it,” said UC Irvine civil engineering professor Brett Sanders, a leading expert on coastal erosion. … UCI grad student Daniel Kahl recently analyzed satellite imagery — a project possible with a $675,000 grant from NASA — to measure beaches through recent decades to find out which are eroding at the fastest pace.

An Orange County coastal town grapples with losing its beach

The Orange County Register -
The shoreline from San Clemente to Dana Point is a microcosm of what issues can arise when the beach disappears from a “beach town” – and how much is at stake for coastal communities when their sand disappears. … UC Irvine civil engineering professor Brett Sanders, a leading expert on sand erosion, said the beach went through what’s called a “tipping point.” South San Clemente had about 200 feet of sand through the 1990s and 2000s, based on satellite imagery analyzed by grad students. … Now, at the point where the railroad damage occurred, there’s no beach at all during higher tides, and only wet sand exposed when tides drop.

Can Southern California save its disappearing beaches?

The Orange County Register -
Sand nourishment isn’t always the best answer. … But UC Irvine civil engineering professor Brett Sanders argues sand replenishment sometimes gets a bad rap. Without sand solutions, some coastal wildlife won’t have places to go. … State Parks is collaborating with UC Irvine to conduct high-tech studies to pinpoint problem areas, said Orange Coast State Parks Superintendent Kevin Pearsall. Researchers are using drone images, topography, monitoring and surveying to measure beaches and track sand movement. [Subscription required, campus-wide access provided by UCI Libraries.

Study reveals new ways microbes might help humans build colonies on Moon, Mars

ANI -
Researchers at the University of California, Irvine have been motivated to consider new ways that microbes can assist humans in colonising the Moon and Mars by studying the biochemical process by which cyanobacteria absorb nutrients from rocks in Chile's Atacama Desert. … Corresponding author David Kisailus, UCI professor of materials science and engineering [said], "Could humans use a similar biochemical approach to obtain and manipulate the minerals that we find valuable? This project has led us down that pathway." Read More

Sea urchins’ sperm pathway could help tiny robots find their way

Interesting Engineering -
University of California, Irvine, and University of Michigan researchers prepared a mathematical model of sea urchin sperm's pathway to grasp its behavior, initially reported by Popular Science. The authors claim that understanding the biological makeup of the sea urchin can be used to create tiny robots that mimic its behavior while taking cues from their environment. Read More
