This paper describes the development of ultra-small-angle X-ray scattering–X-ray photon correlation spectroscopy (USAXS–XPCS). This technique takes advantage of Bonse–Hart crystal optics and is capable of probing the long-time-scale equilibrium and non-equilibrium dynamics of optically opaque materials with prominent features in a scattering vector range between those of dynamic light scattering and conventional XPCS. Instrumental parameters for optimal coherent-scattering operation are described. Two examples are offered to illustrate the applicability and capability of USAXS–XPCS. The first example concerns the equilibrium dynamics of colloidal dispersions of polystyrene microspheres in glycerol at 10, 15 and 20% volume concentrations. The temporal intensity autocorrelation analysis shows that the relaxation time of the microspheres decays monotonically as the scattering vector increases. The second example concerns the non-equilibrium dynamics of a polymer nanocomposite, for which it is demonstrated that USAXS–XPCS can reveal incipient dynamical changes not observable by other techniques.

Coarsening Dynamics

Grazing-Incidence Small Angle X-ray Scattering (GISAXS) and X-Ray Photon Correlation Spectroscopy (XPCS) studies of island growth in two different systems are presented: 5 ML of iron on MgO(001) and 10 ML of iron on Au(001). Due to a missing conducting surface Fe/MgO thinner than approximately 20 ML could not be studied previously by common methods like STM. Fe/Au(001) is interesting as atoms of gold diffuse easily through iron layers and form precipitates. The coarsening dynamics of these precipitates is investigated by XPCS in GISAXS geometry. Their growth depends on the crystallographic directions of the substrate and correlates with the morphology measured by STM microscopy. Measurements were performed at the ESRF in Grenoble.

The coherent X-ray scattering beamline at the 9C port of the upgraded Pohang Light Source (PLS-II) at Pohang Accelerator Laboratory in Korea is introduced. This beamline provides X-rays of 5–20 keV, and targets coherent X-ray experiments such as coherent diffraction imaging and X-ray photon correlation spectroscopy. The main parameters of the beamline are summarized, and some preliminary experimental results are described.

Filler nanoparticles such as carbon black and silica play a vital role in the reinforcement effect of rubber, whereby its viscoelastic and mechanical properties are dramatically improved. The reinforcement effect is of great importance for developing rubber products such as vehicle tires. Its mechanism, however, has not been clarified despite a large number of studies. We have aimed at elucidating the mechanism by clarifying the spatio-temporal hierarchical structure of filler nanoparticles in rubber with various X-ray scattering techniques: ultra-small-angle X-ray scattering (USAXS) for elucidating the hierarchical structures of filler aggregates and their deformation under stretching, and X-ray photon correlation spectroscopy (XPCS) for observing the translational and rotational dynamics of nanoparticles in rubber. For that purpose, we have developed time-resolved two-dimensional USAXS at BL20XU [1] and XPCS at BL40XU, SPirng-8 [2, 3]. Based on the results of these novel scattering experiments, we have characterized spatio-temporal structure of filled rubber system, thereby developing tire products. In this presentation, experimental details and their results will be presented.
