ERC Advanced Grant TimeMan, Rheology of Earth materials: closing the gap between TIME scales in the laboratory and in the MANtle

ERC Advanced Grant TimeMan, Rheology of Earth materials: closing the gap between TIME scales in the laboratory and in the MANtle

2018-2023

Most large-scale geological process such as plate tectonics or mantle convection involve plastic deformation of rocks. With most recent developments, constraining their rheological properties at natural strain-rates is something we can really achieve in the decade to come. Presently, these theological properties are described with empirical equations which are fitted on macroscopic, average properties, obtained in laboratory experiments performed at human timescales. Their extrapolation to Earth’s conditions over several orders of magnitude is highly questionable as demonstrated by recent comparison with surface geophysical observables. Strain rates couple space and time. We cannot expand time, but we can now reduce length scales. By using the new generation of nanomechanical testing machines in transmission electron microscopes, we can have access to elementary deformation mechanisms and, more importantly, we can measure the key physical parameters which control their dynamics. At this scale, we can have access to very slow mechanisms which were previously out of reach. This approach can be complemented by numerical modelling. By using the recent developments in modelling the so-called “rare events”, we will be able to model mechanisms in the same timescales as nanomechanical testing. By combining, nanomechanical testing and advanced numerical modelling of elementary processes I propose to elaborate a new generation of rheological laws, based on the physics of deformation, which will explicitly involve time (i.e. strain rate) and will require no extrapolation to be applied to natural processes. Applied to olivine, the main constituent of the upper mantle, this will provide the first robust, physics-based rheological laws for the lithospheric and asthenospheric mantle to be compared with surface observables and incorporated in geophysical convection models.

 
Interreg Allihentrop - Synthèse et mise en œuvre de revêtements à base d'ALLIages à Haute ENTROPie

Interreg Allihentrop - Synthèse et mise en œuvre de revêtements à base d'ALLIages à Haute ENTROPie

2018-2022

Le projet ALLIHENTROP est porté par un consortium transfrontalier constitué de Materia Nova et du CRIBC (Mons) pour la Belgique, ainsi que du LAMIH (Université Polytechnique Hauts-de-France) et de l’UMET (Université de Lille) pour la région des Hauts de France. ALLIHENTROP propose de développer des revêtements à hautes performances (en termes de dureté, résistance au frottement, ductilité, tenue en température et résistance à la corrosion) formés d’Alliages à Haute Entropie (HEA). Le but est d'apporter une fonctionnalité à une pièce métallique, ou d'en améliorer les performances, et de valoriser ainsi des matériaux supports ou structurels à faible valeur ajoutée. Les méthodes de dépôt sont conçues de manière à être compatibles avec les processus de production industriels. La synthèse et la mise en forme de ces matériaux, ainsi que l'évaluation de leurs performances, requièrent une approche pluridisciplinaire faisant appel à des spécialistes de la modélisation, de la synthèse d’alliages complexes, des dépôts en couches de diverses épaisseurs et des caractérisations physico-chimiques.

 
ANR MISMATCH -- MultIfunctional and Multi-sTimuli responsive Hydrogels

ANR MISMATCH -- MultIfunctional and Multi-sTimuli responsive Hydrogels

2018-2022

Le projet concerne l’élaboration d’hydrogels « intelligents » multi-stimulables et multifonctionnels. L’intérêt de l’approche supramoléculaire préconisée est, qu’en fonction du stimulus ou des stimuli appliqué(s), le matériau pourra répondre différemment et être utilisé pour différentes applications. Dans le cadre de ce projet, ces matériaux trouveront des applications plus particulièrement en tant que senseurs et/ou actuateurs.

European project H2020 : GEMMA for GEneration iv Materials MAturity

2017-2021

The general objective of GEMMA Project is to qualify and codify the selected structural materials for the construction of Generation IV reactors, as envisaged within the European Sustainable Nuclear Industrial Initiative (ESNII). The contribution of UMET covers as well atomic scale simulation studies as mesoscopic scale experimental ones. The density functional theory is used to determine the necessary data required developing a kinetic model of Ni-Cr under thermal conditions and the effect of Fe as a dilute species will be then considered. Due to its recognized expertise in the field of liquid metal embrittlement of structural materials, UMET plans to investigate the mechanical behaviour of new alumina forming austenitic steels and of the 15-15Ti steel in liquid lead and in liquid lead-bismuth at temperatures up to 500°C.

 
ERC Advanced Grant FireBar-Concept, Multi-conceptual design of fire barrier, A systemic approach

ERC Advanced Grant FireBar-Concept, Multi-conceptual design of fire barrier, A systemic approach

2016-2021

The development of science and technology provides the availability of sophisticated products but concurrently, increases the use of combustible materials, in particular organic materials. Those materials are easily flammable and must be flame retarded to make them safer. In case of fire, people must be protected by materials confining and stopping fire. It is one of the goals of the FireBar-Concept project to design materials and assembly of materials exhibiting low flammability, protecting substrates and limiting fire spread. The objective of FireBar-Concept is to make a fire barrier formed at the right time, at the right location and reacting accordingly against thermal constraint (fire scenario).

ANR MADISON

ANR MADISON

2018-2021

MADISON is motivated by our lack of knowledge on the mechanical behavior of key rocks located in subduction zones, where tectonic plate meet. The mechanical strengths of these rocks play a major role on mass transfers at depths, and on shallow, human-impacting processes such as seismicity and volcanism. The rocks physical properties will be studied by three complementary approaches: in-situ experiments, numerical models and natural samples observations.

ANR NanoPiC - Etude du comportement piézoélectrique multi-échelles de composites innovants micro- et nano-structurés

2016-2020

Le projet NanoPiC a pour objectif de mener un programme de recherche et de développement de matériaux piézoélectriques innovants et ayant des propriétés améliorées, à partir de composites céramiques - polymère structurés.

RheoMan: a five-year, ERC-funded (Advanced Grant), project to model the rheology of the Earth's mantle

RheoMan: a five-year, ERC-funded (Advanced Grant), project to model the rheology of the Earth's mantle

2012-2018

The goal of RheoMan is to model the rheology of the Earth’s mantle from the properties of its constitutive minerals and rocks. It proposes a novel approach based on multiscale modelling of rheology. The goal of multiscale modelling is to link our understanding of a few elementary mechanisms (usually at the microscopic scale) with a behaviour observed at the macroscopic scale. In solids, plastic deformation results from the motion of crystal defects: point defects, dislocations, grain boundaries.
