Copper nanoparticles, green laser light cost beneficial in circuitry printing

Copper nanoparticles, green laser light cost beneficial in circuitry printing

Science
Sept. 13 (UPI) -- Printing electronic circuitry with copper nanoparticle ink and green laser light can be more cost beneficial and efficient, according to a study. Researchers at Soonchunhyang University in South Korea studied the thin-film printing technique instead of the conventional methods, based on laser power, scanning speed, pre-baking conditions and film thickness effects. Their findings were published this week in the journal AIP Advances. Nanoparticles in metallic inks have an advantage over bulk metals because of their lower melting points in the circuitry manufacturing. Originally the researchers, led by Kye-Si Kwon, tested silver nanoparticle ink but found it is costlier. Then, they studied studied copper, which is derived from copper oxide. Although copper's melting point ...
Large-scale wind and solar power 'could green the Sahara'

Large-scale wind and solar power 'could green the Sahara'

Science
Installing huge numbers of solar panels and wind turbines in the Sahara desert would have a major impact on rainfall, vegetation and temperatures, researchers say.They found that the actions of wind turbines would double the amount of rain that would fall in the region.Solar panels have a similar impact although they act in a different way. The authors say their work reinforces the view that large-scale renewables could transform the Sahara region. The scientists modelled what would happen if 9 million sq km of the Sahara desert was covered in renewable energy sources. They focussed on this area because it is sparsely populated, and it is also exposed to significant amounts of sun and wind and is close to large energy markets in ...
Green Bay Packers camp setup: Healthy Aaron Rodgers a must

Green Bay Packers camp setup: Healthy Aaron Rodgers a must

Sports
DE PERE, Wisc. -- In every way imaginable, the Green Bay Packers went backward in 2017. Green Bay failed to reach the postseason for the first time since 2008. The Packers' 7-9 record was the second worst of Mike McCarthy's 12 seasons as head coach. And after reaching the NFC Championship Game in both 2014 and 2016, the Packers were eliminated from the playoffs by mid-December. Green Bay could be poised for a bounce-back season, though. The Packers return nine starters on each side of the ball and addressed several positions of weakness in free agency. Most important, though, quarterback Aaron Rodgers returns after missing nearly 10 full games last season with a broken collarbone. At the end of the Packers' offseason program, McCarthy called it "one of our best offseasons, just as f...
Aviation sector in Alberta working to green up

Aviation sector in Alberta working to green up

Business
July 19 (UPI) -- Greenhouse gas emissions from Alberta are on the decline in part because of alternate fuels in the transportation sector, leaders said. The provincial government of Alberta announced $ 53 million (USD) is available through its Emissions Reduction Alberta Biotechnology, Electricity and Sustainable Transportation program. The funding would draw in new investments that would diversify the oil-rich economy. Teresa Ehman, the director of environmental affairs for Air Canada, said the company is investing billions of dollars in building a fuel-efficient and cleaner fleet. "To date, we have operated eight biofuel flights and will continue to advocate for the development of sustainable aviation biofuels in Canada," she said in a statement. The International Civil Aviation Organi...
Green in legal fight with FRC over BHS probe

Green in legal fight with FRC over BHS probe

Business
The high street billionaire Sir Philip Green has sparked a legal battle with regulators over a probe into the audit of BHS's accounts during the year before the now-collapsed chain was sold for £1. Sky News can exclusively reveal that Sir Philip's company Taveta Investments has made an urgent application for a judicial review aimed at forcing the Financial Reporting Council (FRC) to amend its report on the issue.A hearing is understood to have been scheduled to take place at the High Court on Friday, but has been postponed after lawyers for the FRC requested more time to prepare their case, according to insiders.Taveta, which is the parent company of Sir Philip's Top Shop-owning Arcadia Group, is also thought to have applied separately for an injunction to prevent the...
