Times Cited Count:10 Percentile:88.88(Chemistry, Applied)Crystallinity is reflected in the mechanical properties of foods and materials. Crystallinity should be related to the structural dynamics of starch. In this study, we used quasi-elastic neutron scattering (QENS) to investigate changes in the molecular dynamics of cooked rice starch during retrogradation. The width of the measured QENS narrowed with retrogradation. The elastic incoherent structure factor (EISF) increased, which indicated that the molecular dynamics are spatially suppressed upon retrogradation. Analysis of EISF with a bimodal continuous diffusion model, where low and high mobilities are assumed to correspond to crystalline and amorphous phases, respectively, showed that the fraction of the low-mobility component increases with retrogradation.

Times Cited Count:1 Percentile:18.99(Materials Science, Multidisciplinary)We investigated the electronic structure of the MgZnY alloy using hard and soft X-ray photoemission spectroscopy and electronic band structure calculations to understand the mechanism of the phase stability of this material. Electronic structure of the MgZnY alloy showed a semi-metallic electronic structure with a pseudo-gap at the Fermi level. The observed electronic structure of the MgZnY alloy suggests that the presence of a pseudogap structure is responsible for phase stability.

Times Cited Count:38 Percentile:82.08(Physics, Multidisciplinary)We study a field-induced quantum phase in the weakly-coupled ferromagnetic frustrated chain LiCuVO by a neutron diffraction technique. A new incommensurate magnetic peak is observed at H 8.5 T. The field-dependent propagation vector is identified with the spin density wave correlation in the theoretically predicted magnetic quadrupole order. Quantum fluctuation, geometrical frustration, and interchain interaction induce an exotic spin density wave long-range order in the insulating magnet.

We, Materials Sciences Research Center (MSRC) of Japan Atomic Energy Agency (JAEA) are engaged in material science researches by using neutron and synchrotron radiation X-ray. MSRC owns 14 neutron scattering instruments at the 20 MW multipurpose research reactor JRR-3 and 3 of them are served in inelastic and quasielastic scattering experiments. TAS-1 (Triple-Axis Spectrometer-1) is a polarization neutron capable thermal-neutron TAS installed at the reactor hall. TAS-2 (Triple-Axis Spectrometer-2) is installed at a guide-end port of one of thermal-neutron guides in the guide hall. LTAS (Low Energy Triple-Axis Spectrometer) is a cold-neutron TAS installed at a cold-neutron guide in the guide hall. In this presentation, we will show the overview of our inelastic instruments, recent out-comes and future perspective.
