Red wine is a popular marinade for meat, but it turns out that it may become a popular treatment for creating iron based superconductors as well (Link to academic paper): Last year, a group of Japanese physicists grabbed headlines around the world by announcing that they could induce superconductivity in a sample of iron telluride by soaking it in red wine. They found that other alcoholic drinks also worked–white wine, beer, sake and so on — but red wine was by far the best. The question, of course, is why. What is it about red wine that does the trick? Today, these guys provide an answer, at least in part. Keita Deguchi at the National Institute for Materials Science in Tsukuba, Japan, and a few buddies, say the mystery ingredient is tartaric acid and have the experimental data to show that it plays an important role in the process. . . It turns out that the best performer is a wine made from the gamay grape–for the connoisseurs, that’s a 2009 Beajoulais from the Paul Beaudet winery in central France.
As we soak our cable connections, we might recall that on this date in 1860, M L. Byrn of New York City, N.Y., was issued a patent for an improved corkscrew – a “covered gimlet screw with a ‘T’ handle” (No. 27,615). The inventor claimed the design would provide greater strength and durability and which could be manufactured at less cost than prior construction methods using a spiral twist of steel wire that gradually tapered from the handle to the point. Byrn claimed the gimlet-type screw with wider threads would also be strong enough to “remove a bung of the hardest wood from a barel or hogshead.”
