DailyDirt: Closer To Understanding Superconductivity
from the urls-we-dig-up dept
The phenomenon of superconductivity could be extremely useful -- if the materials that exhibit the behavior could do so at ambient conditions. The first material discovered to conduct electricity with no resistance was mercury in 1911, but mercury requires temperatures below 10 °K to do this. In 1986, a high temperature superconductor was found that seemed to work around liquid nitrogen temperatures. We've made some progress pushing the limits of the superconductors we've made so far, and it looks like we may be on the cusp of a much better understanding these materials and how they work. Here are just a few links on the matter.- Superconductivity at room temperature has been an unattainable goal for decades (or almost a century), until recently. Using short infrared laser pulses, a ceramic material was made superconducting at room temperature... for only a few picoseconds. [url]
- Over 60,000 papers have been published on so-called high temperature superconductors since 1986, but the phenomenon is not well understood at all. The "high temperatures" above -237 °C are still pretty chilly, but it's been hard to find examples of different superconductors that could help elucidate the mechanism. Researchers have recently discovered a new class of superconducting material, but we're still a long way from really understanding what's going on. [url]
- Physicists are starting to come up with better explanations for superconductivity and how it occurs. There doesn't seem to be any good reasons why superconductivity can't persist at room temperatures, but there may very well be practical barriers that we just haven't found yet. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

One reason for the lack of progress in understanding is ...
I will not be surprised when the current crop of models are laid to rest and completely new models are put in place. There are a number of alternatives, some of which date back to the 1920's or there-about which are being revived which have the potential of a much better view of the natural world.

Supposedly, from what I could understand of it, they would run cooler. I had heard they got the expenses down pretty low, in making them.
I thought this was going to be one of the ways, they hoped to develop superconductors?
Had you heard of this process? If so, would it aid in the process of superconducting?
