This vanadium dioxide discovery has such cool (ha!) implications, especially because it’s properties seem tuneable by mixing with other materials. Imagine transparent window glass that’s thermally conductive above 65F and thermally insulating below.

Not this rubbish story again, it keeps circulating bad science
Charles Batchelor​ Movement of the electrons.
MidnightVisions its in the late Jan issue of Science. It’s new research. newscenter.lbl.gov – For This Metal, Electricity Flows, But Not the Heat | Berkeley Lab
Corina Marinescu for your reading pleasure 🙂
MidnightVisions This is the first time I came across it, I didn’t realize it was old. Can you explain or provide a source to explain why you think it’s rubbish?
Chris Dolan this story had been posted multi times and the issues that the material gets around the heat by being a ceramic rather than a metal. Past arguments then moved to the authors trickery with wording, then discredited the authors over this wording trickery. These were not my words or arguments, I just got tired of seeing this article reposted, with the same statements, while the arguments that correct the articles technical points don’t follow in Google plus comments. That being said, Google plus has been clearing out posts older than 24 hrs from showing in the stream, so it’s getting very hard to point out these past corrections.
MidnightVisions Interesting, thanks for the reply. I’ll research this more deeply and if I come to agree with you I’ll put up a new post. I certainly don’t want to be one who propagates flaky news.
quick search in google scholar is not finding criticisms of Wu’s work. There is a 1987 article saying the transition obeys Mott’s rule. http://iopscience.iop.org/article/10.1088/0953-8984/12/41/310/meta
nice
