Robert Dynes was at the center of SC before he moved to USCD. His published analysis closed down the superconducting supercomputer research in 1983. SC materials are not good, fast switchers and cannot compete with Si/SiO2.
Sperry Rand went out of business as a result. He did not contribute to the theory of SC chemistry. ________________________________ From: mix...@bigpond.com <mix...@bigpond.com> Sent: Monday, August 6, 2018 11:05 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:This could be the start of something big In reply to JonesBeene's message of Mon, 6 Aug 2018 08:15:34 -0700: Hi, [snip] >Robert Dynes of UCSD found that the transition temperature of lead (Pb) >increased when it was in contact with silver.

If the transition temperature increases, I think that makes it a better superconductor, not worse. As to why it increased, I suspect it's because the two metals have different work functions, resulting in electron migration, and a matching change in the lattice constants of the Pb, which in turn would alter the Tc.
