| Abstract(E) | We developed the novel neutron microscope on the instrument iMATERIA at MLF of J-PARC, which was originally a powder diffractometer, recently reinforced by small-angle scattering. The method of dynamic nuclear polarization (DNP) for protons was combined with small angle neutron scattering (SANS) (DNP-SANS). In a long course of history of DNP, our activity is the first challenge to incorporate DNP-SANS for routine industry uses. This "neutron microscope" provides us multiple reciprocal space images by changing scattering lengths of proton, in turn by varying "contrast" of individual scattering components. The DNP approach is suitable for industry application (for example to observe tire rubbers), because we do not need highly-specialized deuterium substitution, which has been conventional. We report the studies on vulcanized SBR rubber. We also report the studies on the polymer electrolyte fuel cell (PEFC) by using ultra-small-angle neutron scattering and/or deuterium gas contrast variation methods. |
