The Front Cover shows historic glass earrings with brass mountings from the Hamburg Museum in the background. The metal parts exhibit severe corrosion, especially where they are in contact with glass. The partial dissolution of the historic glass by moisture leads to a surface film containing formates produced by a Canizzaro reaction of formaldehyde, emitted by, e.g., wooden furniture, with the alkaline components of the film. An excerpt of the crystal structure of a new corrosion phase, Zn 4 Cu 3 (Zn 1– x Cu x ) 6 (HCOO) 8 (OH) 18 ·6(H 2 O) (“Zinc C”), is presented. More information can be found in the Full Paper by S. Bette et al. For more on the story behind the cover research, see the Cover Profile .
