Research Interests
Prof. Giessen's materials chemical research is principally in two
areas, much of it done in interdisciplinary cooperations with
physicists and engineers in the framework of the Materials Science
Division of the Barnett Institute. These research areas are: new
ceramic cuprate superconductors with high critical temperatures and
high critical currents prepared by new processes described in a
series of patents; and plasma surface modification of metals by ion
nitriding, especially stainless steels with corrosion-resistant
single phase constitution of interest to the chemical industry.
Important tools are X-ray diffraction (pole figure analysis),
electron and scanning tunneling microscopy, magnetometry and
scanning calorimetry. This research is often conducted in
association with industrial firms.
An additional, interdisciplinary research topic (with the Economics
Department) concerns the econometric analysis of usage, supply and
pricing patterns of chemicals and materials, using pattern
recognition and other advanced computer methods. In this research
area, supply, demand and pricing patterns of commercial commodities
and other types of futures are studied by analytical techniques,
using computer programs written by associated staff and students.
