Rings and a few other things : A method for the preparation of uniform mesoscopic titanium dioxide rings that are bound in a periodic array on a substrate, linked to a free‐standing membrane, or are dispersed as individual particles (see SEM image) is presented. The technique is based on the selective wetting of the inner surface of a porous membrane.
