In 2001, researchers found that a nondescript compound, magnesium diboride, transforms into a superconductor at a temperature slightly close to the absolute temperature of 40K (- 233 °C).
ໃນປີ 2001, ນັກຄົ້ນຄວ້າພົບວ່າສານປະສົມ nondescript, magnesium diboride, ປ່ຽນເປັນ superconductor ໃນອຸນຫະພູມເລັກນ້ອຍໃກ້ກັບອຸນຫະພູມສະເພາະຂອງ 40K (- 233 °C).
