Sharks' answer to bone: how calcified cartilage evolved and its relation to feeding.

Emilie PEDERSEN · Isabel BREET · Kathleen DOLLMAN · Richard DEARDEN · y 2 más

Sharks and their relatives (chondrichthyans) have a unique skeleton made entirely of cartilage, unlike other jawed vertebrates. Tessellated calcified cartilage (TCC) provides the skeleton with both flexibility and stiffness, and fossil evidence shows that chondrichthyans developed this innovative tissue in place of bon...

Connecting oxygen vacancy formation to the exsolution behavior of perovskite oxides

Jessica MICHALKE · Hedda DREXLER · Jonathan ROLLENITZ · Tobias BERGER · y 3 más

We propose a PDF/pXRD beamtime in which we want to investigate the role oxygen vacancy formation has on the exsolution of metallic nanoparticles (= migrating parts of the material to the surface, without destruction of the host, thus enhancing catalytic activity) in perovskite-oxides, a material used in heterogeneous c...

Tunable Periodic Screw Dislocation Networks in Twisted SrTiO3 Thin Layers Transferred onto SrTiO3 Substrate via Wafer Bonding

Jeremy MALTITZ · Carsten RICHTER (ORCID: 0000-0002-4230-215X) · Martin SCHMIDBAUER · Nils BLANC · y 2 más

Twisted perovskites represent a novel class of materials that enables a variety of fascinating novel applications in the field of nanoengineering. In the present proposal, we aim to investigate epitaxial SrTiO3 thin films that are deposited on SrTiO3 substrates by means of layer transfer and subsequent wafer bonding. T...

Silk threads spun by bagworms (Psychidae) show superb mechanical properties, resulting from a highly ordered fibrillar organization. The SAXS/WAXD analyses using nanoscale X-ray beam for a single bagworm silk (performed at ESRF, ID-13 beamline during SC5011and 5259) resolved an anisotropic structural feature made of a...

Temperature dependence of the non-ergodicity factor of vitreous GeO2

Fabio BRUGNARA · Daniele MARZI · Alberto RONCA · IRENE FESTI · y 4 más

We propose to measure the temperature dependence of the non-ergodicity factor in vitreous germanium oxide, v-GeO2, through the X-ray photon correlation spectroscopy (XPCS). We aim to compare the slow dynamics probed here with the fast dynamics determined by IXS in the same Q range. This comprehensive investigation will...

HERFD-XAS and XES study of Ag in PbS

OLGA FILIMONOVA · Jan KAMENSKÝ · Anton KUTYREV

In natural deposits, the majority of the Ag enriches sulphide minerals or forms its own phases. The contents of Ag and Sb(or Bi) in galena are often positively correlated. Up to 1.5 wt% of Ag concentrates in the pure PbS, and up to 5 wt% solutes in galena in the presence of Sb(or Bi). Based on the HRTEM, EPMA, and SEM/...

Investigating the structure-activity correlation of Fe-based catalysts during H2 production via CH4 pyrolysis by combined operando PXRD and

Alessandra BERETTA · Kirill LOMACHENKO · Chiara NEGRI · Lidia CASTOLDI · y 2 más

Fe-based catalysts are active catalysts for the catalytic decomposition of methane, key-reaction for the energy transition, which leads to pure H2 and solid C. Despite the interest, a full comprehension of the structure-activity relationship for Fe-based catalysts is still under way. In our group we focused on experime...

Transformation of iron oxides in oscillating redox and sulfidic conditions and its implications for phosphate immobilization in aquatic ecos

HESTER BLOMMAERT · Antonio AGUILAR · Mathilde DEHUE · Robin HINTZEN · y 1 más

Excessive phosphorus (P) in surface water ecosystems is a primary cause of eutrophication, and chemical immobilization using Fe-rich materials is a commonly used approach to mitigate eutrophication due to their high affinity toward P. However, the long-term effect of Fe addition on P dynamics at the sediment-water inte...
