Researchers at Jamia Millia Islamia, New Delhi, have developed an ultrasensitive quantum thermometer which can measure micro Kelvin changes in temperature and has quick response time. The results of the study were published in the journal Nanoscale Advances.
About:
Material used: This ultrasensitive quantum thermometer has been developed using graphene quantum dots (GQDs).
Features:
The thermometer has high sensitivity when measuring different temperatures and can measure very minute (micro Kelvin) changes in temperature.
The thermometer has extreme quick response time of just about 300 milliseconds to register a change in temperature from 27 degree C to –196 degree C.
Applications: The device can find widespread applications in cryogenic temperature sensing. It will be useful in the pharmaceutical industry, healthcare to measure the incubation temperature of biological cells and molecules and the automobile industry to measure the ignition temperature within the engine.
