Air-purifying church windows early nanotechnology
Read the full story from the Queensland University of Technology.
Stained glass windows that are painted with gold purify the air when they are lit up by sunlight, a team of Queensland University of Technology experts have discovered.
Associate Professor Zhu Huai Yong, from QUT’s School of Physical and Chemical Sciences said that glaziers in medieval forges were the first nanotechnologists who produced colours with gold nanoparticles of different sizes.
Professor Zhu said numerous church windows across Europe were decorated with glass coloured in gold nanoparticles.
