Zaibudeen A.W.

Zaibudeen A.W., and John Philip, scientists at Indira Gandhi Centre for Atomic research (IGCAR) at Kalpakkam (Tamil Nadu) have developed whereby body temperature could seen rather than being read over a thermometer. In a study published in the journal, Optical Materials, the two scientists have described the concept in which ferrofluid emulsion contained in a thin film changes colour with rise in temperature within a narrow range of 30 to 40 degree Celsius.
