Dr. Bernhard Blümich, professor of macromolecular chemistry at the Technical University of Aachen in Germany, will present a seminar on nuclear magnetic resonance (NMR) April 16 from 3:10-4:00 p.m. in Glover 201 on the Colorado State University campus. The seminar is sponsored by the Colorado State University Rocky Mountain Magnetic Resonance Center and the Department of Chemical Engineering.
Blümich's research interests include methods and applications
of solid-state NMR spectroscopy, NMR imaging in material science and chemical
engineering, and mobile NMR for process and quality control.
Research Abstract:
NMR imaging is known for its superior contrast in soft matter. For this reason, NMR imaging is well suited not only for medical diagnostics of human tissue but also for applications in the polymer and elastomer field as well as for the analysis of flow in a chemical engineering environment. However, conventional NMR is bound to the laboratory and cannot be carried to the object of interest. On the other hand mobile NMR was developed for logging oil wells, and this approach can be generalized for technical applications in a production environment. Unilateral NMR devices have been developed for local inspection of large objects from one side. Here the magnetic fields are inhomogeneous, and in contrast to conventional NMR relaxation-type information is measured instead of spectroscopic information. By incorporating pulsed gradient fields into unilateral NMR devices, sensors are obtained which are capable of measuring local images and flow fields from selected volume sections in large objects similar in their use to a magnifying glass. Examples of conventional and unilateral NMR are given for measuring images at flow fields, addressing quality issues of polymer and elastomer products as well as fundamental flow studies with relevance to chemical engineering.
The Rocky Mountain Magnetic Resonance Center was established to foster the development and application of nuclear magnetic resonance to a broad range of areas in science and society.
