re: EE Times corrects story on silane as a potential superconductor

Perhaps you have corrected the article, but you still need to correct the title. The abstract of the paper in Science states that the compressed silane became superconducting below 17 Kelvin, which is -256 C or -429 F.

I forgot to add that Si is the best characterized material on the planet, so this may be easier to achieve than my estimate of 10 years.

Obviously, this is a very early stage research result, but it's not that difficult to make a practical superconducting material out of it - it's mainly a materials-engineering issue. It's not necessary to use a diamond anvil to get the high pressures necessary - it may be possible to use a material that can adsorb SiH4 instead - maybe a metal or metal-hydroxide that can trap SiH4 in a crystalline lattice and retain it at enormous pressure from molecular-scale forces alone (if you think about it, that's how previous High-Tc perovksite materials actually work). It's a non-trivial engineering challenge, but well within reach over a decade for any reasonable materials lab in the industry.

"Max Plank Institute?" For shame. Of all the people in the world, you ought to know how to spell the name of one of the great physicists of the 20th century, whose name graces the basic equations of quantum mechanics. And not just once, but you misspelled it twice. WTF kind of journalism is this? One wonders if your fact-checking is as shoddy as your knowledge of physics history.

THIS IS FANTASTIC NEWS !!!!! thats what I think... although commercial applications could take some time and engineering, a new area of superconductor research directed towards a whole new horizon of applications is a possibility which is more than near with this break through !!

of course it will take a couple of years to get the material in a stable casing but I think it has quite some potential.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
