It is longer than an age but shorter than a period. The geological periods basically reflect the natural patterns and changes of Earth… Continue reading Scientists give the thumbs-up for Anthropocene epoch
Finally,IISc team confirms breakthrough in superconductivity at room temperature
Recently,researchers from the IISc,Bengaluru has achieved breakthrough in ambient superconductivity which normally requires extremely low temperatures and extremely high pressure. Superconductivity is the phenomenon in which a material offers zero or vanishingly low resistance to the passage of electrical current below a certain temperature called its critical temperature (Tc). Since the mid-20th century,scientists have been… Continue reading Finally,IISc team confirms breakthrough in superconductivity at room temperature
