History of superconductivity also be used i.e. the spinel battery material LiTi2Ox and the lattice pressure can increase Tc to over 13.8K Also LiHx has been theorized to metallise at a substantially lower pressure than H and could be a candidate for a Type 1 superconductor. Papers by H.K. Onnes BCS theory Other key papers Patents History of superconductivity Superconductivity is the phenomenon of certain materials exhibiting zero electrical resistance and the expulsion of magnetic fields below a characteristic temperature. The history of superconductivity began with Dutch physicist Heike Kamerlingh Onnes's discovery of superconductivity in mercury in 1911. Since then, many other superconducting
Absolute zero could not be liquefied. Decades later, in 1873 Dutch theoretical scientist Johannes Diderik van der Waals demonstrated that these gases could be liquefied, but only under conditions of very high pressure and very low temperatures. In 1877, Louis Paul Cailletet in France and Raoul Pictet in Switzerland succeeded in producing the first droplets of liquid air . This was followed in 1883 by the production of liquid oxygen by the Polish professors Zygmunt Wróblewski and Karol Olszewski. Scottish chemist and physicist James Dewar and the Dutch physicist Heike Kamerlingh Onnes took on the challenge to liquefy the remaining gases hydrogen
