Achieving superconductor operation at room temperature was a goal that for decades seemed unattainable. Now it is possible. Until now it was necessary to be very cold, well below zero, which is difficult to achieve outside the laboratory.
That’s right, a group of researchers managed to generate superconductivity at room temperature in a laboratory using a compound that contains hydrogen, sulfur and carbon, which allowed it to be generated at a temperature of 13.3C, the highest ever reached.
It should be noted that this result was obtained under extremely high pressures, which were 2 million times higher than the air we breathe, a milestone according to the computational physicist at the La Sapienza University of Rome, Jos Flores-Livas, who despite not Being a participant in the work expressed his admiration for the achievement, also emphasizing the progress achieved over the previous indexes of -75 and -23 degrees Celsius.
Initially, the researchers proceeded to mix carbon and sulfur, elements that were later ground into small balls. These were then squeezed between 2 diamonds, adding hydrogen gas in the process.
Subsequently, a laser was illuminated for several hours in the compound in order to break the bonds present between the sulfur atoms and thus be able to alter both the chemistry of the system and the behavior of the electrons, resulting in a superconducting crystal at low pressures. .
Added to this, the smallness of the crystal is remarkable, which reaches a size of about 30 millionths of a meter in diameter due to the high pressures generated by superconduction.
Despite the feat achieved, researchers have not yet been able to provide exact details that explain the dynamics involved in the operation of this compound due to little understanding of it.
However, initiatives have been taken to develop tools that allow us to decipher this unknown, so that researchers can later make the necessary adjustments in the composition in order to maintain the superconducting properties in the compound, even when it is at low pressures.
