  • What is the state of trust in scientists around the world? To answer this question, the authors surveyed 71,922 respondents in 68 countries and found that trust in scientists is moderately high.

  • Literature produced inconsistent findings regarding the links between extreme weather events and climate policy support across regions, populations and events. This global study offers a holistic assessment of these relationships and highlights the role of subjective attribution.

  • We visualized the spatial inhomogeneity of chain orientation on the submicron scale in high-density polyethylene associated with strain-induced density fluctuations using STXM and USAXS/SAXS/WAXD. Real-space images of the density fluctuations were obtained with STXM at the strain where a butterfly pattern was observed with USAXS. STXM observation also revealed that the chains in the low-density region were more often oriented parallel to the stretching direction than those in the high-density region.

  • A new beamline called the frontier soft-material beamline at BL03XU for soft materials was recently installed at SPring-8, using an in-vacuum undulator. The photon flux can reach 1013 photons sec−1 and the energy resolution is about 10−4 at an energy of 12.4 keV. The present paper introduces details on the instrumental and some of the first scattering data measured at BL03XU, revealing its cutting-edge design and high performance.

  • The new experimental system has been launched by coupling with the measurement techniques, which are grazing incidence small/wide-angle X-ray Scattering (GISWAXS) and grazing incidence X-ray diffraction (GIXD), as well as X-ray reflectivity (XR), at the BL03XU of SPring-8. Using this integrated system, we can achieve to measure the hierarchical structure of the same sample.

  • A poly(4-methylpentene-1) (P4MP1) film was prepared on a quartz substrate, which was a model system of interfaces in a filler-reinforced semicrystalline polymer composite. Grazing-incidence wide-angle X-ray diffraction measurements revealed that P4MP1 in the film after the isothermal crystallization formed a Form I crystal polymorph, in which the chain axis was oriented along the direction parallel to the quartz interface. Combining sum-frequency generation vibrational spectroscopy with molecular dynamics simulation enabled us to study the local conformation of P4MP1 chains at the quartz interface and the changes that occurred with isothermal crystallization.
