Carbon dioxide is a desired feedstock for platform molecules, such as carbon monoxide or higher hydrocarbons, from which we will be able to make many different useful, value-added chemicals. Its catalytic hydrogenation over abundant metals requires the amalgamation of theoretical knowledge with materials design. Here leverage understanding structure sensitivity, along library supports, tune selectivity methanation in Power-to-Gas concept nickel. For example, show that nickel can and does...
Bone is a complex, biological tissue made up primarily of collagen fibrils and biomineral nanoparticles. The importance hierarchical organization in bone was realized early on, but the actual interplay between structural features properties on nanostructural crystallographic level still matter intense discussion. only mineralized that can be remodeled and, at start formation new during this process, structure called cement line formed which regular grows. Here, orientational relationship...
The biomineralization of bone remains a puzzle. During Haversian remodeling in the dense human cortical bone, osteoclasts excavate tunnel that is then filled by osteoblasts with layers varying fibril orientations, resulting lamellar motif. Such represents an excellent possibility to increase our understanding as material well studying spatio/temporal variations biomineral across osteon. To this end, fluorescence computed tomography and diffraction scattering sub-micrometer resolution applied...
Computed tomography spans a versatile set of techniques that range several length scales and modalities. It is common to them all the sample must be prepared in way which allows for addressing scientific question(s) posed as well being suitable specific setup experiment. We present two lathe-based preparation workflows developed prepare biomineralized samples (here bone) very different experiments terms setup, types questions asked, requirements. The first experiment, involving measurement...
The stomatopod Odontodactylus scyllarus uses weaponized club-like appendages to attack its prey. These clubs are made of apatite, chitin, amorphous calcium carbonate, and phosphate organized in a highly hierarchical structure with multiple regions layers. We follow the development biomineralized club as function time using harvested at specific times since molting. investigated broad suite techniques unravel biomineralization history clubs. Nano focus synchrotron x-ray diffraction...
Bone has a complex hierarchical structure, which is essential for its performance. typically replete with cells called osteocytes that are embedded in the mineralized bone matrix osteocyte lacunae, interconnected by canaliculi only few hundred nanometer wide to form vast cellular network. Our understanding of lacuno-canalicular network been limited because difficulties image within opaque 3D. Synchrotron X-ray computed tomography ideally suited study it combines high penetration power X rays...
Composite materials, both biominerals such as bone or shells but also increasingly synthetic often have a complex hierarchical 3D structure ranging over several length scales. To fully understand the of method for probing nanoscale in is needed. Materials are particularly challenging due to their composition and structure. Recent developments synchrotron x-ray focusing optics paved way smaller beams with high brilliance. Herein, we present how probe elemental distribution crystallographic...
