Thermal Materials
An international research team has used a "thermal metamaterial" to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories.
IN HIGH TEMPERATURES, A NEW CLASS OF CERAMICS CONTROLS HEAT RADIATION
Manufacturers frequently use coatings to protect the structural stability of engines or power generators operating at high temperatures.
NEW ANTENNA TECH TO EQUIP CERAMIC COATINGS WITH HEAT RADIATION CONTROL
The gas turbines powering aircraft engines rely on ceramic coatings that ensure structural stability at high temperatures. But these coatings don’t control heat radiation, limiting the performance of the engine.
CONTROLLING HEAT WITH CERAMIC NANOTUBES
New ceramic nanotubes could prolong aircraft engine coatings by controlling hightemperature heat radiation. Idha Valeur reports.
Metamaterials operating at frequency ranges in which the dielectric permittivity is close to zero have been discussed for use across a wide range of optical applications.
