Nanotechnology creates switchable mirror
Researchers in the Energy Control Thin Film Group of the Materials Research Institute for Sustainable Development, a part of the National Institute of Advance Industrial Science and Technology (AIST) have developed a new nanotechnology thin film material for a switchable mirror that can be switched between reflective and transparent states.
The thin film forms a reflecting mirror when it is applied to the glass, but it turns transparent when it is exposed to an atmosphere that contains hydrogen but no oxygen; it reverts to a reflective state when it is exposed to an atmosphere that contains oxygen but no hydrogen.
