Atomic layer deposition (ALD) of controlled-thickness TiO 2 films was carried out on particle substrates in a fluidized bed reactor for the first time. Films were deposited on 550 nm SiO 2 spheres and 65 nm ZnO nanoparticles for enhanced optical properties. Nanoparticles were fluidized with the assi

Membrane walls composed of vertical tubes connected by fins, as shown in Figure , are commonly employed as heattransfer surfaces to remove heat from circulating-fluidized bed (CFB) combustors. The riser reactors are rectangular or square in cross section. The membrane tubes influence the dynamics of
