One way to increase the rate of an electrochemical process is to increase the area of the interface between the electrode and the electrolyte. A novel polymer electrode, with a very high effective surface area and a nanometer‐scale continuous conducting network that extends into a large volume, is presented and its preparation from a commercially available aqueous dispersion of a conducting polymer described. An application to supercapacitors is detailed, as a demonstration of the properties that are a consequence of the unique structure of the material.

Randianin, a haemolytic active saponin from Randia dumetorum, and some of its isomers with different carbohydrate side chains have been synthesized from oleanolic acid. The in¯uence of the linkage within the disaccharide residue on the haemolytic activity of these glycosides has been investigated.
