Abstract: The present work introduces a new solar selective absorber coating (SSAC) for the receiver tube of Concentrated Solar Power (CSP) systems, proposing silver as an infrared reflector application at 550 °C. In past, Italian National Agency New Technologies, Energy and Sustainable Economic Development (ENEA) has developed SSACs suitable applications °C, featuring absorbers based on graded multilayer cermet WN-AlN W-Al2O3 tungsten. Although these coatings ensured properly stable...
We report on the self-assembling of clusters gold-nanoparticles (Au-NPs) directed by phase separation poly(styrene)-b-poly(methylmethacrylate) (PS-b-PMMA) block-copolymer (BCP) indium tin oxide coated glass, which induces onset vertical lamellar domains. After thermal evaporation gold BCP, Au-NPs 4 nm are selectively included into PS-nanodomains annealing, and then clustered with large density hot spots (> 10(4) μm(2)) in a random two-dimensional pattern.
