Thin films of amorphous and crystalline tungsten trioxide were deposited onto glass covered with indium tin oxide, by reactive dc magnetron sputtering. The samples were intercalated with Li ions in 1M LiClO4 in propylene carbonate. The infrared refle

The temperature of a nanosatellite in orbit varies strongly as it goes into earth shadow or solar radiation. A variable emittance panel built with an electrochromic material, could improve the temperature control by providing an adaptive thermal cont
