Making small changes in the composition can change the transition temperature of the alloy significantly.
The rise in transition temperatures has stalled again, well below room temperature.
"If someone comes up with a transition temperature to two or three significant figures, you know that guy is wrong."
When cooled below its transition temperature, it has zero electrical resistance.
The critical transition temperature can be adjusted over a wide range by variations in chemistry.
The predicted benefit in superconducting transition temperature was therefore a factor of about 300.
The transition temperature is the unique point where the different curves cross.
For sulphur, the transition temperature at one atmosphere is 368.5 K.
Further increase of the pressure reduces the transition temperature usually.
Superconducting transition temperatures up to 20 K have been observed in this case.
