Ceramic Nanotube Coating Controls Heat Radiation

Ceramic Nanotube Coating Controls Heat Radiation
A ceramic ‘antennae’ able to control heat radiation could increase the performance of gas turbines.

Typically, gas turbines such as those in aircraft engines feature ceramic-coated components to help the unit withstand high temperatures without damage. The new coating developed by the team from Purdue University takes the protection a step further by with the incorporation of ceramic nanotubes made of boron nitride that will function as ‘thermal antennas’ to control heat radiation. According to the team, this level of control could improve performance by providing enhanced cooling, and could even be used to send information in specific directions.
