Better camouflage is needed to hide from new electronic sensors

The Economist -
A team at the University of California, Irvine is designing infrared camouflage by embedding tiny metal flakes into thin sheets of rubber. These sheets can then be incorporated into clothing. … Both designs would add but a trivial amount of weight to military fatigues, notes Alon Gorodetsky, a professor of chemical and biomolecular engineering at Irvine, who leads the project. The technology, he says, could be ready within a few years. Such materials, he adds, might also be used as insulation for the better control of heat flows in electronics. Read More

Hydrogen may help replace fossil fuels in California — but it’s still a greenhouse gas

Desert Sun -
DWP is hardly the only Californian institution rushing to commit to hydrogen. SoCalGas, one of the state’s largest natural gas utilities, hopes to blend hydrogen into the gas network that supplies homes and businesses across Southern California. To do that, it has begun work on a massive hydrogen pipeline project called the Angeles Link, and is planning tests in campus buildings at UC Irvine. Meanwhile, a Bay Area transit agency is preparing to manufacture hydrogen to power a new train line linking Alameda and San Joaquin counties. Read More

Electric generators will fill a critical role in developing hydrogen in the LA area, analysis finds

Utility Dive -
Analysis from the University of California, Irvine, concluded that green hydrogen could provide about 20% of the emissions reductions needed for Los Angeles to comply with federal smog standards …. In a four-month period modeled by UC Irvine, the improved air quality would result in 27 fewer deaths, 960 fewer hospitalizations and 7,500 fewer lost work days, said Michael MacKinnon, a senior scientist in the advanced power and energy program at UC Irvine. … Developing a green hydrogen industry could also support more than 28,000 full-time jobs in the LA area, compared to the 22,000 jobs currently supported by the natural gas and refining industries, according to Jeffrey Reed, chief scientist for renewable fuels and energy storage at UC Irvine.

Human cells hacked to act like squid skin cells could unlock key to camouflage

Ars Technica -
"In general, there's two ways you can achieve transparency," UC Irvine's Alon Gorodetsky, associate professor, chemical & biomolecular engineering], who has been fascinated by squid camouflage for the last decade or so, said during a media briefing at the ACS meeting. "One way is by reducing how much light is absorbed—pigment-based coloration, typically. Another way is by changing how light is scattered, typically by modifying differences in the refractive index." The latter is the focus of his lab's research. Read More

Human cells help researchers understand squid camouflage

Science Daily -
For many years, Alon Gorodetsky, Ph.D., and his research group have been working on materials inspired by squid. In past work, they developed "invisibility stickers," which consisted of bacterially produced squid reflectin proteins that were adhered onto sticky tape. "So then, we had this crazy idea to see whether we could capture some aspect of the ability of squid skin tissues to change transparency within human cell cultures," says Gorodetsky, who is the principal investigator on the project.

"So then, we had this crazy idea to see whether we could capture some aspect of the ability of squid skin tissues to change transparency within human cell cultures," says Gorodetsky, who is the principal investigator on the project. The team at the University of California, Irvine focused their efforts on cephalopod cells called leucophores, which have particulate-like nanostructures composed of reflectin proteins that scatter light.

Mammalian Cells Help Researchers Study Squid Transparency

Laboratory Equipment -
Typically, scientists use animals to study humans, but researchers at the University of California, Irvine reversed the system in their newest research. At the American Chemical Society 2023 meeting, researchers detailed how they used human cells to better understand squid camouflage. … “We had this crazy idea to see whether we could capture some aspect of the ability of squid skin tissues to change transparency within human cell cultures,” said PI [and Associate Professor] Alon Gorodetsky, whose research group has been working on materials inspired by squid.

Engineer breaks Guinness World Record

The Circuit News -
A UC Irvine engineer is breaking a Guinness World Record using a drone and an internet connection. Under the direction of Peter Burke, [professor of electrical engineering and computer science], a drone in Irvine, California, was remotely operated by a pilot 11,000 miles away on a French island in the Indian Ocean. This new technology can be used in a variety of applications from rescue missions and railway safety inspections to water, forest and land surveying. [Starts :52] Read More
