University research team members brainstorm idea to safeguard artworks

A new type of nanomaterial developed by a university research team in Xi'an, capital of Shaanxi province, has been used to protect murals.

Li Xuanhua, a professor at the School of Materials Science and Engineering at Northwestern Polytechnical University, said nanotechnology breaks down inorganic materials in the murals into small particles.

These particles can be better applied to the murals in an effort to protect them.
