Using operando XRD to identify the role and nature of Fe Carbide species for methane pyrolysis

Andrew Michael BEALE · Ilenia GIARNIERI · Jakub DRNEC · Antonia BOBITAN · y 1 más

The performance of methane pyrolysis catalysis is strongly influenced by the nature and properties of the supported metal however their exact relationship is still unknown. Of the most successfully applied metals for this reaction, Fe-based catalysts are considered the most robust, environmentally friendly and earth ab...

In situ X-ray diffraction study of Iron-Magnesium binary system during isothermal compressions at high pressure and high temperature.

Jérôme ANDRIEUX · Guillaume DEFFRENNES · Guillaume MORARD · Mathias DESSEAUX (ORCID: 0009-0002-6185-239X) · y 3 más

The objective is to study in situ the structural behaviour of the iron-magnesium binary systems during isothermal compressions at different temperature (1500K, 1800K and 2000K from 20-40 GPa to 100 GPa) in order to obtain new experimental data which will be used for the reassessment of Fe-Mg CALPHAD High temperature-Hi...

Experimental study of the P-T stability of phlogopite in metasomatised peridotite with varying H2O contents in the deep cratonic lithosphere

Wilson CRICHTON · Greg YAXLEY · Anja ROSENTHAL

Phlogopite is an important metasomatic, hydrous, potassic phase in peridotite from on- and off-cratonic lithospheric mantle. It is significant in the petrogenesis of mantle-derived magmas, including micaceous kimberlites, ultramafic lamprophyres, kamafugites, lamproites, which are all potential sources of diamonds. We...

Surface elasticity effects in pin-hole contact with radial clearance

Radi, E.

This work investigates the frictionless contact of a loaded rigid circular pin inserted with radial clearance into a circular hole in an infinite isotropic elastic plane, with the hole boundary described by surface elasticity theory. The problem is motivated by small-scale mechanical systems and by surface-treated pin...

Visible/near infrared spectroscopy in muscle beef analysis: How device choice and sampling affect prediction accuracy

Lopez, Annalaura · HOCQUETTE, Jean-François · GRAULET, Benoit · Constant, Isabelle · y 10 más

This study evaluated the performance of two portable spectral devices (visible: Vis; near‑infrared: NIR) and one benchtop combined Vis/NIR instrument for predicting beef biochemical traits related to meat quality. A total of 497 muscle samples were collected from 55 fattening farms across five European countries. Refer...

Statistical treatment of searches for counterparts of positionally-uncertain astrophysical sources: From flux upper limits to detection

Julian Sitarek · Abelardo Moralejo · Juan Jiménez Quiles · Giacomo D’Amico · y 2 más

Rapid growth of the multimessenger and multiwavelength astrophysics had led to an increasing number of observations of the same events with instruments with different point spread functions. In particular pointing instruments with good angular resolution are used to pin-point the source of poorly-localized alert. In ca...

Towards Pressure Triggered Phase Transition, an Experimental Observation of Charge Density Redistribution in Gypsum

Roman GAJDA · JOAO ELIAS FIGUEIREDO SOARES RODRIGUES · Mohamed MEZOUAR · Julia ALBERSKA · y 2 más

Gypsum CaSO4·2H2O is one of the most common hydrated minerals in Earth’s crust. In this project we focus on the high pressure (>4 GPa) phase transition to gypsum-II to experimentally determine quantitative charge density redistribution. The use of quantum crystallography offers a better understanding of interactions wi...

Effect of matrix stiffness on ionomics and drug resistance in ovarian cancer

Murielle SALOME · Lorella PASCOLO · Anna FLAMIGNI · Cristina TUFONI · y 1 más

Extracellular matrix (ECM) stiffness provides signals that control cell proliferation, differentiation and death in both physiological and pathological conditions. The proposal aims to investigate the relationship between ECM stiffness and cancer invasion and, in turn, the abundance of endogenous ions and metal within...

CryoEM-BAG France: Structural biology using cryoEM in France

Rhian JONES · Romain LINARES · Celia PLISSON-CHASTANG

This proposal gathers Principal Investigators from Institutes across France that use cryoEM to unravel the molecular mechanisms associated with different fundamental biological processes. Scientists belong to 12 centres that currently use CM01 for cryoEM. PIs in this application were part of the previous BAG MX2596, wi...
