“…The lateral gradient is approximately linear for the u-shaped sensor and zero for the barmagnet sensor. Depth resolution can be achieved with dedicated magnet configurations such as (12)(13)(14). In the first two cases, the magnet is derived from the U-shaped concept, but by splitting the magnets (13).…”

“…The entire apparatus was 30ϫ 30 cm 2 . 107 Recently, profile NMR-MOUSE has been developed with a thin, flat sensitive volume that is suited for measuring depth profiles with a spatial resolution of 5 m. 108 The scanner can move relative to the sample in order to obtain the different investigation depths and is able to cover a 500 m FOV with 5 min acquisition time.…”

The anomalous adsorbate dynamics at surfaces in porous media studied by nuclear magnetic resonance methods. The orientational structure factor and Lévy walks J. Chem. Phys. 109, 6929 (1998) Recent years have seen significant progress in the NMR study of porous media from natural and industrial sources and of cultural significance such as paintings. This paper provides a brief outline of the recent technical development of NMR in this area. These advances are relevant for broad NMR applications in material characterization.

“…One of the most important features of a unilateral NMR sensor is its capacity to analyze objects non-destructively because the portable stray-field magnet does not need to be in a direct contact with the sample and does not restrict the sample size [19,20]. In the characterization of polymers, unilateral NMR has been successfully used in the investigation of aging and cross-link density as a function of depth in elastomers and polyethylene [21][22][23][24][25].…”

Time-Resolved Study of the Photo-Curing Process of Dental Resins with the NMR-MOUSE

et al. 2013

The photo-curing reaction of dental resins has been examined with unilateral nuclear magnetic resonance (NMR-MOUSE) allowing nondestructive high-resolution measurement of depth profiles as a function of time and space. The NMR signal is sensitive to both the monomer concentration and changes in molecular mobility. Upon irradiation with blue light, it first increases due to molecular mobility enhanced by the reaction heat and then decreases exponentially with the monomer concentration as the polymer signal is lost in the dead time of the instrument upon curing. The space and time dependence of the NMR signal can be described by the photo-polymerization reaction kinetics together with a heuristic approximation of the temperature dependence.
