From Pasta to Superconductor In Four Easy Steps

GA

From Chem. Commun., 2013, ASAP (DOI: 10.1039/C3CC38271K)

Seriously. From the abstract:

"Self-supporting superconducting replicas of pasta shapes are reported, yielding products of differing 3D architectures. Functioning high-temperature superconductor wires are developed and refined from replicas of spaghetti, demonstrating a unique sol–gel processing technique for the design and synthesis of novel macroscopic morphologies of complex functional materials."

Huh? And it gets better in the 'General Experimental' section:

"Spaghetti (own-brand durum wheat dried pasta) was purchased from The Co-operative Food (Co-operative Group Limited, UK), penne and fusilli (own-brand durum wheat dried pasta) were purchased from Sainsbury’s (J. Sainsbury’s plc, UK) and HonigTM Samen “Piraten Pasta” was a gift from Jamie Shenston (University of Bristol, UK) and Caroline Walker (Heinz)... Unless stated otherwise, all materials were used as received, and with no further purification."

The pasta is then soaked in a delicious blend of yttrium, barium, copper and silver (until green), oven baked at 920 ºC (gas mark 36, if you're trying this in your oven at home), sintered and annealed to taste then served in liquid helium. Yum!

Thanks to occasional commenter Martyn for pointing this out!

  1. If that were the case, they would be obligated to release your car
    if you were to discover them in the act of securing it to their truck,
    which they never do unless you pay them their fine
    on the spot. Having its own governing body will provide the opportunity
    for complaints against specific tow truckers to be registered,
    as well as offenders of the law to be penalized. On one occasion, because I had commercial cleaning chemicals at my disposal, I was
    only coerced into giving the perpetrators my money to secure my release.
