The research activities of Prof. Blümich aim at understanding the macroscopic properties of advanced polymer and functional porous materials by NMR on a microscopic and molecular basis. To this end he develops and applies NMR methods for NMR spectroscopy of liquids and solids, NMR imaging of heterogeneous materials and fluid flow, and measurements of NMR relaxation and diffusion. Bernhard Blümich has pioneered several methodical innovations concerning multidimensional NMR spectroscopy with noise excitation, 1D and 2D methods of studying molecular motion in solids, solid-state imaging, and flow NMR. A growing focus in his recent work is the development of magnets for compact NMR such as the NMR-MOUSE for non-destructive materials testing and permanent magnets with homogeneous fields for chemical analysis by 1H NMR spectroscopy under the fume hood and reaction monitoring. The magnet technology has been commercialized in an RWTH spin-off company ACT GmbH, which has merged with Magritek Ltd in 2012. Today the Magritek is the leading manufacturer of tabletop NMR spectrometers.
