Cover: Wetting Modification by Photocatalysis 

Photoactive semiconductor oxides, such as titanium dioxide, display intriguing wetting properties: their surface can be modified by functionalization with organic moieties to prepare superhydrorepellent materials, whereas, upon light irradiation, these materials become superhydrophilic through photocatalysis. In Wetting Modification by Photocatalysis: A Hands-on Activity To Demonstrate Photoactivated Reactions at Semiconductor Surfaces, Luca Rimoldi, Tommaso Taroni, and Daniela Meroni present a laboratory activity aimed at providing students with basic knowledge about photocatalysis and surface science. The cover shows the process of photocatalytic lithography, in which patterned surfaces are prepared with superhydrophilic/superhydrophobic contrast. Upon irradiation through a paper photomask, the irradiated areas become superhydrophilic, while the covered areas retain their superhydrophobicity. These contrasting properties are revealed by pouring an aqueous dye solution on the film.
