"Hot" New Superconductors Discovered

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.

    Funny enough, here's a quote from superconductivity.org/Links.htm:

    Note: The link for Elsevier Science/Physica C has been removed. Elsevier Publishing has facilitated the theft of intellectual property belonging to Superconductors.ORG. And, despite repeated requests, refuses to redress the problem. Elsevier Science/Physica C is NOT a trustworthy source of superconductor information.

    Also, this is bullshit: http://www.superconductors.org/woman.htm [superconductors.org].

    No, that is merely a joke older than me and from your attitude, certainly older than you.
