"For centuries people appreciated only the beautiful works of art, and long life of the colors, but little did they realize that these works of art are also, in modern language, photocatalytic air purifier with nanostructured gold catalyst," said Zhu Huai Yong, a material scientist at the Queensland University of Technology...

Science is just so very cool!
