Description
Superconductivity being a gray area of research for the past four decades now is still a hot topic for discussion. It was discovered in 1911 by kammerling Onne’s where a mercury wire upon immersed in liquid helium realized an abrupt change of resistance to zero. Further research has been conducted until today to unravel a superconductor that can operate at room temperature and ambient pressure possibly so that technological advancement can take off worldwide. Superconducting power lines need a single crystal for example in order to reduce resistance to carry enormous amount of power without losses on transmission, MRI machines need to be built without a lead joint material since lead is poisonous and so very harmful to human health yet it’s still in use till today on these machines yet the same are operated by people. The many superconductors that have been unravelled by researcher in superconductivity just to mention: the hydrides, cuprites polyhydrides and heavy fermion materials, none has depicted that possibility to operate within the room temperature. The latest superconductor , the polyhydrides showed conformity within which we can conclude that they are superconductors however, experimental results shows that they could not exclude the magnetic field from their internal structure , which is the Meissner effect that defines superconductivity. A quick check will be sintering and fabricating the binary cerium based and uranium based superconductors, which are heavy fermions to test their physical and thermal properties including but not limited to exclusion of magnetic fields and results analysed optically and by x –ray spectroscopy before a material is tested on an MRI joint then conclusion will be drawn.
