Biological materials obtain their properties through hierarchical structuring. Understanding such materials calls for multimodal and multiscale approaches. Based on two example systems, bone and shell, we discuss current analytical approaches, their capabilities and limits, and how to tie them together to fully cover the different length scales involved in understanding materials' functions. We will further discuss advances in this area and future developments, the possible roadblocks (radiation damage, data quantity, sample preparation) and potential ways to overcome them.
NEUTRON | SYNCHROTRON
Coherent X-ray diffraction imaging and 3D X-ray fluorescence were used to visualize in 3D the self-transformation of polycrystalline microspheres of calcium carbonate into hollow and core-shell microspheroid hierarchical structures.

A comprehensive review about the use of micro- and nanostructured superhydrophobic surfaces as a tool for in situ X-ray scattering investigations of soft matter and biological materials.
research papers
Grazing-incidence small-angle X-ray scattering (GISAXS) is used to examine crystalline and locally quasicrystalline 2D photonic structures produced by nanoimprint lithography for photovoltaic applications. Using a hierarchical theoretical description, lattice distortions are quantified from the GISAXS measurements, showing the differences in reproduction quality between the investigated samples.
X-ray spectroscopy for functional materials
The RefXAS database under DAPHNE4NFDI enables users to access quality-controlled, curated X-ray absorption spectra of references along with important metadata and to share their data with the research community in easy steps.

A new model for the interpretation of small-angle neutron scattering data from aqueous foams is presented and validated using experimental data from a model foam system.
research papers
The rapid growth of the World Wide Web provides major new opportunities for distributed databases, especially in macromolecular science. A new generation of technology, based on structured documents (SD) and XML, is being developed which will integrate documents and data in a seamless manner.

The most fascinating natural examples of nanocomposite materials are represented by so-called biominerals, acting as functional materials in living systems. In particular, apatite-organic (protein) nanocomposites are the main components of bone and teeth hard tissues of vertebrates (including humans) [1]. Biomimetic systems provide an excellent possibility to get deeper insight into the fundamental principles of structuring, organization and formation of biominerals. Therefore, our investigations are focused on biomimetic fluorapatite-gelatine nanocomposites grown by double-diffusion in gelatine gels [2]. In the gelatine gel protein molecules interact with the ions in solution in such a way that they provide nucleation positions for nano apatite and, in this way, give rise to dramatic processes of self-organization and hierarchical composite formation. Numerous experimental observations (by means of XRD, SEM, HRTEM, EH, etc.) together with atomistic computer simulations reveal the material to be best described as a mosaic-dominated nanocomposite superstructure. Furthermore intrinsic electric dipole fields, generated by a non-classical crystallization process of composite nanoboards, cause the integration of a meso/macroscopic pattern of gelatine microfibrils into the superstructure matrix and govern morphogenetic process of fluorapatite-gelatine nanocomposites [3].
