George Andermann recieved his B.S. in 1949 from UCLA. He worked in industry until 1963 and then returned to school to recieve his M.S. in 1961 and Ph.D. in 1965, both from USC. He joined the University of Hawaii in 1965. He was awarded a NATO Senior Fellowship in 1973. His research interests are physical-analytical chemistry, material science, cold fusion, and chemical physics.

Our Research areas include:
In 1981 we completed the construction of a unique, high resolution (0.005 to 0.1 eV) 5 M grating spectrometer dedicated for ultrasoft (lambda>10Å) XFS studies of chemical bonding using photographic and photoelectric detection. In 1984, we developed a new accessory based on variable grazing angle sample optics to achieve surface analysis capability with XFS. Current plans include:
In our studies (C&EN, 5/8/85 p. 28) we demonstrated that variable angle XFS is a useful surface-thin film analytical tool in terms of non-destructive sample depth profiling in an overall thickness (t) range of 10 to 106Å with elemental and chemical speciation analytical capabilities for micro and macroscopic characterization (1). This technique can be utilized with ultrahigh vacuum or with real world, ambient sample surface conditions. For lambda<10Å interfacial studies involving solids, liquids, and gases are feasible. Applications have included the determination of thickness of multilayer systems of interest in magnetic thin films, and detailed evaluation of corrosion of Cu, Fe, Ni, Co, Cr and Al. Current interests include corrosion studies of metal surfaces in methanol fuel systems in alternate energy development. Recently (2), in cooperation with IBM we have discovered a non-destructive methodology for characterizing 'buried' interfaces. Studying various Mn-Oxides, we have found that using L Beta/L alpha intensity ratio values lead us to believe that there may be a charge transfer between Mn and O atoms (3). Using the L beta/ L alpha intensity ratio techniques on Cu-Oxide high Tc superconductors, it was found that this ratio had to be 0.33 for any material to superconduct (4). At the recent 2000 Pac. Chem. Congress we have provided a terse review of our 35 years of involvement in molecular, high- resolution XFS (5). We have summed up our experiences in using XFS as a central atom and a ligand atom probe in studying valence electron structures of some 85 different compounds. At this Congress we also disclosed that very low electron kinetic energies, below about 1 KeV, were extremely efficient in exciting ultra-soft X-ray spectra, providing trace analysis at surfaces, or limits of detection, for example, of Al, in the picogram range (6). At the same Congress we showed that Carbon K and Iron L emission spectroscopies are useful tools in characterizing methanol induced corrosion products obtained with galvanostatic treatment of iron surfaces(7) .We also reported (8) that our select ferro-manganese crust's Carbon K emission was primarily due to organic compounds rather than inorganic carbonates. We also showed at this Congress that our select marine ferro-manganese crust material had unusually high and selective sorption characteristics for gases with possible application in air pollution control (9). Finally, at this Congress we also presented data on anomalous Si Solubility in a select ferro-manganese crust (10). Currently (11,12) we are developing a new theoretical model to rationalize the events reported by investigators for the so-called 'cold fusion' phenomenon. The proposed model is based on the electron capture of the D 1s electron to yield a di-neutron, Nu. The subsequent thermal adsorption of Nu is responsible for the reported 'cold fusion' events. Preliminary experiments are under way.
