waste heat

This transmission electron microscope image shows a single silicon nanowire. Thermoelectric materials convert heat to electricity and vice versa. Most fossil-fuel-powered engines generate waste heat, so researchers are using nanotechnologies to explore ways of making thermoelectric devices more efficient in...

This is a scanning electron microscope image of a silicon nanowire array synthesized for thermoelectric applications. Thermoelectric materials convert heat to electricity and vice versa. Most fossil-fuel-powered engines generate waste heat, so researchers are using nanotechnologies to explore ways of...
