Position-Resolved Small-Angle X-ray Scattering of Complex Biological Materials

摘要: Many biological materials, like bone or wood, are hierarchically organized and optimized at all levels for their specific mechanical function. At the lowest level, these materials fiber composites, where direction as well size of individual components varies considerably with position inside a given specimen. For some parameters can be readily obtained by small-angle X-ray scattering (SAXS) in position-resolved way. A scanning-SAXS system based on pinhole camera rotating anode area detector is presented, first applications to study wood reported.
