Joe Eck's Superconductors.org is reporting the discovery of the 25th and 26th high-temperature superconductors. Sn9SbTe4Ba2MnCu15O30+ displays a critical transition temperature (Tc) near 136°C (276°F) and Sn10SbTe4Ba2MnCu16O32+ transitions near 141°C (285°F).

To grasp how exceptionally high these temperatures are, consider that 141 Celsius is warmer than the melting points of more than 45 different solder alloys.

These two new formulations resulted from expanding the unit cell of the 129C superconductor announced in March 2015. One extra Sn-Cu-O2 layer was added to reach 136C and two extra Sn-Cu-O2 layers were added to reach 141C.

    You asked for the whole world to be connected on the internet and now you got it, and its not all /r/gonewild and rule 34 sometimes you're gonna see stuff that offends your sensibilities like (possibly overly) speculative basic research notebooks.

    I love how you posit that speculative science is more offensive than rule 34..

    I like how they both have a knee graph where "more is better" for some distance along the graph and then you hit the "eh a little too weird" and instantly its pitchforks and burning at stake time. Oh and everyone's got a different spot for that crazy knee where the paradigm suddenly shifts from "more tentacles" to "ugh too many tentacles must bleach eyes" or whatever.
