Beschreibung
Zusammenfassung:	This invention comprises methods for manufacture, and the manufacture of nanoparticle structures for use in heat transfer applications in which enhanced radiative heat transfer is desired. Nanoparticle structures can be made using chemical, lithographic or other methods, and can be made into a variety of structures having predefined physical sizes. Nanoparticles can be made of different sizes or shapes to accommodate design requirements. Nanoparticle structures used in heat pipes can have a particles of different sizes incorporated into the same structure, and the inter-particle distances can be selected to provide broad band heat absorptive and emissive properties. Alternatively, nanoparticle structures can be designed and manufactured to provide narrow band absorptive and/or emissive properties.
