Superconductivity
Why is it in news?
- Recently, a team from the Indian Institute of Science (IISc), Bengaluru has confirmed that the material they tested exhibits major properties of superconductivity at ambient temperature and pressure.

- What is superconductor?: A material is said to be a superconductor if it conducts electricity with nil resistance to the flow of electrons.
- Application: Superconductors will help build very high efficiency devices leading to huge energy savings.
- Significance of the research:(1) Until now, scientists have been able to make materials superconduct only at temperature much below zero degree C and hence making practical utility very difficult.(2) This is where the IISc’s work becomes particularly important.(3) The material that exhibited superconductivity is in the form of nanosized films and pellets made of silver nanoparticles embedded in a gold matrix.(4) Interestingly, silver and gold independently do not exhibit superconductivity.
