Of these seven, three have found properties similar to those claimed for LK-99, but not superconductivity. The remaining four observed neither magnetism nor superconductivity. Ben Turner
Get a quoteIn a paper recently published in the journal Science, researchers report a breakthrough in our understanding of the origins of superconductivity at relatively high (though still frigid) temperatures. The findings concern a class of superconductors that has puzzled scientists since 1986, called ''cuprates.''. "There was tremendous excitement ...

Get a quoteMost superconducting materials must be at a very low temperature, often close to absolute zero (-459°F, -273°C), or very high pressure (more than 100,000 times atmospheric pressure) to exhibit superconductivity. This is because, in these extreme conditions, the electrons in the material pair up and form what''s known as Cooper pairs.
