Acoustic velocites of enstatite at mantle PT conditions

Billy RAYNER · Andrew THOMSON · Ry AFFLECK · Anja ROSENTHAL

We are proposing to measure the acoustic velocity (vs and vp) of enstatite, the second most abundant mineral in ultramafic assemblages at depths extending to ~ 400 km beneath Earth’s surface. MgSiO3 enstatite and FeSiO3 ferrosilite are both known to undergo a series of pressure- and temperature-induced phase transition...

Establishing reference density profiles of the Earth’s inner core

Giacomo CRINITI (ORCID: 0000-0002-9414-523X) · Lola PERRUCHON-MONGE · JOAO ELIAS FIGUEIREDO SOARES RODRIGUES · Silvia BOCCATO · y 4 más

The goal of this proposal is to establish density profiles of the Earth’s inner core by determining equations of state (EOS) of iron alloys at inner core conditions. The inner core has 3-4% density deficit compared with density of pure Fe. Interpretation of the density deficit requires accurate density measurements of...

Operando X-ray Raman Scattering for Probing Lattice Oxygen Mediated Pathways in Electrocatalysts for the Oxygen Evolution Reaction

Connor SHERWIN · Peixi CONG · Robert WEATHERUP · Christoph SAHLE · y 2 más

The adoption of electrolyser technology for hydrogen production by water splitting is hampered by the high overpotential of the oxygen evolution reaction (OER). The recently identified Lattice Oxygen Mediated (LOM) mechanism for OER offers a promising route to significantly improve the efficiency of water splitting. O...

GROS: A General Robust Aggregation Strategy

Cholaquidis, Alejandro · Joly, Emilien · Moreno, Leonardo

A new, very general, robust procedure for combining estimators in metric spaces is introduced GROS. The method is reminiscent of the well-known median of means, as described in \cite{devroye2016sub}. Initially, the sample is divided into $K$ groups. Subsequently, an estimator is computed for each group. Finally, these...

Soft tissue preservation in Paleozoic jawed vertebrates

Alan PRADEL · Alicia SÁNCHEZ GIMENO · Vincent FERNANDEZ · Francois CLARAC

We recently discovered new well 3D-preserved jawed vertebrates in two Paleozoic (540-240 Ma) deposits, one in Uruguay, the other in Peru. Exceptionally, in addition to some muscles associated to the head, we found a mineralized brain in a cartilaginous fish (sharks, rays and chimaeras) and probably in a stem jawed vert...

RIXS characterization of sub-stoichiometric tungsten oxide films for transparent electric contacts

Enrico BERGAMASCO · Marco MORETTI · SILVIA MARIA PIETRALUNGA · JULIA KUESPERT · y 3 más

We propose employing RIXS characterization to qualify the electronic structure of sub-stoichiometric WO3-x thin films, in view of applications such as transparent electric contacts. Oxygen-deficient WO3-x exhibits high electrical conductivity, concurrently it displays enhanced optical absorption within the visible-to-N...

Munich Crystallography BAG

Christoph MUELLER DIECKMANN · Tulika CHAKRABORTTY · Katja LAMMENS · Andre MOURAO · y 2 más

The diverse groups of the Munich Crystallography BAG study a far range of subjects, reaching from structural aspects of fundamental cellular processes - such as RNA processing, protein folding and degradation, DNA repair, chromatin remodelling, enzymes - to the design of foldamers. The research groups are located at th...
