New Lead (Pb) Free Material

Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, led by Prof. Kanishka Biswas have now identified a lead-free material called Cadmium (Cd) doped Silver Antimony Telluride (AgSbTe2) which can efficiently allow recovery of electricity from ‘waste heat’.It can efficiently convert waste heat to power our small home equipment and automobiles.

Cadmium (Cd) doped Silver Antimony Telluride (AgSbTe2)

  • They doped (internally introduced) Silver Antimony Telluride with Cadmium (Cd) and used an advanced electron microscopy technique to visualize the resultant ordering of atoms in nanometre scale.
  • The nanometre-scale atomic ordering scatters phonons that carries heat in a solid and ....
