Researchers have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices.
adminDrivers are seeing more hydrogen fuel cell electric vehicles on the road, but refueling stations for those vehicles are still few and far between. This is about to change. One reason is the Hydrogen Station Equipment Performance device, or HyStEP, which will greatly accelerate station commissioning.
The transportation sector has the capacity to nearly halve its carbon dioxide emissions by 2050 and, hence, to contribute far more than previously thought to mitigate greenhouse gas emissions. Realizing this would require further efficiency improvement and, especially, promotion of public transport in cities, alongside with a large-scale shift to electric cars, concludes a recent study.
Eve AndrewsHappy Roe v. Wade Day, everyone! Forty-three years ago today, the Supreme Court decided that a woman’s right to choose is protected under the Constitution. That’s not, for the record, because the U.S. Constitution makes any mention of reproductive rights, or uteri, or, for that matter, women at all — the right to choose falls under our constitutional “right to privacy.” (For a wonderful explanation of this, please read Jill Lepore’s New Yorker piece from last spring.) My generation has only known a post-Roe v. Wade America, and many (hi, Debbie Wasserman Schultz) claim that makes us “complacent” as our reproductive rights are trampled by overzealous state governments. To which I would respond: Well, we may spend literal days watching Scandal, but…
CIGSe solar cells are made of a thin chalcopyrite layer consisting of copper, indium, gallium and selenium and can reach high efficiencies. Since indium is becoming scarce and expensive, it is interesting to reduce the active CIGSe layer, which however decreases the efficiency quite strongly. Now, scientists have produced high quality ultrathin CIGSe layers and increased their efficiency by an array of tiny nanoparticles between the back contact and the active layer.
Finding a technology to shift carbon dioxide, the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream. Now, a team of chemists says they have developed a technology to economically convert atmospheric CO2 directly into highly valued carbon nanofibers for industrial and consumer products.
