Windows that block heat only on hot days: New research brings us closer
(PhysOrg.com) -- New materials science research from the University at Buffalo could hasten the creation of "smart" windows that reflect heat from the sun on hot summer days but let in the heat in colder weather.
"By preparing vanadium oxide as a nanomaterial instead of in bulk, the scientists managed to lower the compound's trigger point from 153 degrees Fahrenheit to 90. Doping vanadium oxide  with tungsten brought the temperature down further, to 7 degrees Fahrenheit.  doping had a similar but smaller effect."
