This is the Ph.D. Thesis of Dr. Christopher Stiles Johnson from Northwestern University (1992). The thesis consists of the understanding of electron transfer events at metal oxide electrodes in aqueous electrolytes, methanol electrooxidation at iridium oxide electrodes, and the electrochemistry of multi-electron reactions of transition metal coordination compounds of rhenium dioxo pyridyl complexes.

Bond Interaction

Metal-coordination bond interaction within molecular junctions was revealed to significantly facilitate electron transfer between single molecules. Such facilitation was utilized to construct bistable molecular switches activated by a single metal ion.

We have already described (1.2.3) a device using a pockel's effect light valve as a microscopical electron image converter. This converter can be read out with incoherent or coherent light. In the last case we can set in line with the converter an optical diffractometer. Now, electron microscopy developments have pointed out different advantages of diffractometry. Indeed diffractogram of an image of a thin amorphous part of a specimen gives information about electron transfer function and a single look at a diffractogram informs on focus, drift, residual astigmatism, and after standardizing, on periods resolved (4.5.6). These informations are obvious from diffractogram but are usualy obtained from a micrograph, so that a correction of electron microscope parameters cannot be realized before recording the micrograph. Diffractometer allows also processing of images by setting spatial filters in diffractogram plane (7) or by reconstruction of Fraunhofer image (8). Using Electrotitus read out with coherent light and fitted to a diffractometer; all these possibilities may be realized in pseudoreal time, so that working parameters may be optimally adjusted before recording a micrograph or before processing an image.
