title: Metastable β-Bi2O3 Nanoparticles with Potential for Photocatalytic Water Purification Using Visible Light Irradiation.
abstract: Invited for this month's cover is the group of Prof. Michael Mehring. The cover picture shows the degradation of the model dye rhodamine B (RhB) in water using β-Bi2O3 nanoparticles as photocatalyst, which was prepared from pre-organized bismuth oxido clusters.
