Description
Mechanical properties of biological materials are strongly dependent on the nano- and microstructure of the materials. By measuring the orientation of fibers or nanocrystallites it is possible to gain insight into their physical properties. Standard X-ray diffraction is a well-established technique for this kind of measurements but needs multiple measurements involving sample rotation to reconstruct the fiber orientation, which is often not easily doable for biological samples due to their complex morphology.
We present an alternative approach, where crystallographic texture information can be obtained in a single measurement, called Energy Dispersive Laue Diffraction (EDLD). The newly set-up X-ray Color Camera Microscope hosts a modern, pixelated CCD-based X-ray detector, and can provide direct detection of X-rays with both energy and spatial resolution. Using a broad spectrum of photon energy, sample rotation is not needed to provide three-dimensional information in a single shot. We will show measurements on different biological materials from the synchrotron as well as from the lab setup, using a modern high-flux lab source.
