present a novel method to acquire reliable scanning tunnelling spectra using iron electrodes in borate media. They provide the first quantitative map of the electronic density within the oxide as a function of both the electron energy and the electrode potential. The method can be relevantly used for the study of corrosion, catalysis and redox biomolecules.

A. K. Schaper from the Philipps University in Marburg, Germany, and co-workers present a study of the special care required for investigations with electron microscopy of natural organic and synthetic nanomaterails sensitive to high-energy electrons. Their work used naturally grown nanotubes with normal and cryogenic scanning electron microscopy, as well as template-grown nanotubes and nanorods containing discotic liquids with transmission electron diffraction and microscopy at lowdose conditions, high efficiency image acquisition, cryoprotection and additional data from electron energy filtering observations.
