Élucider les secrets de la formation de la croûte des planètes. La faible densité de la croûte continentale de la planète pourrait avoir donné naissance à la tectonique des plaques, à savoir les mouvements de la lithosphère de la Terre. Des études ont révélé que cette faible densité trouve son origine dans des processus qui ont affecté la répartition des matériaux à travers les continents. Cependant, il existe encore des lacunes dans nos connaissances concernant les caractéristiques de la croûte sur d’autres planètes telluriques et la manière dont elle s’est formée. Plus particulièrement, des processus physiques analogues pourraient-ils se produire sur d’autres planètes dépourvues de tectonique des plaques? Le projet CRUSLID, financé par l’UE, cherche à combler ces lacunes en développant un modèle révolutionnaire qui permettra de déterminer les caractéristiques de la croûte d’autres planètes. Pour ce faire, il tirera parti de recherches multidisciplinaires et de nouvelles observations planétaires susceptibles de fournir de précieuses informations sur la formation de la croûte des corps telluriques primitifs.

One of the most fascinating and challenging question of Modern Astrophysics is: How do planets form? Indeed, micronic dust grains must grow over 30 orders of magnitude in mass to build planet cores. Global numerical simulations of dust grains that couple the dynamics of the particles to their growth/fragmentation and the radiation in the disc are compulsory to understand this process. Yet, this coupling has never been realised, given tremendous difficulties that originate from fundamental physical properties of dusty flows. The evolution of the dust distribution in protoplanetary discs remains therefore very poorly understood. Our novel groundbreaking code is the first to handle non-ideal MHD, radiation and dust with dynamical growth and fragmentation. We can therefore overcome all past difficulties to model gasgrains mixtures in discs consistently. PODCAST is designed to study the different stages of gas and dust evolution in the various regions of the disc, with the main objective of combining these steps in a holistic model for planet formation. We will confront the results directly with observations, unleashing the full potential of the grand instruments ALMA, SPHERE, JWST and SKA.

Mechanical instabilities of thin sheets has long been exploited in Nature to create patterns and ensure vital functions such as stimuli responsiveness. By applying forces at the surface of thin objects, it is possible to create a wide variety of chiral 3D shapes such as helices, twists and rolls. Moreover, minute changes on these forces can induce dramatic shape-shifting between different geometries. Our goal is to use this general principle to establish a new class of chiral and addressable nanostructures that current synthetic strategies can not afford. Building on our pioneering results, i will use organic ligands at the surface of two dimensional colloidal nanoplatelets to bend and twist ultrathin nanosheets into complex shapes. We first aim at establishing generic synthetic principles for colloidal 2D materials. To do so, we will develop in situ scattering methods to get atomistic insight on their formation mechanism. We will then determine the link between surface chemistry, interfacial stress and conformation in a set of model systems. Based on these insights, we will design stimuli responsive surface ligands whose conformational change upon excitation by an external stimuli will impact the nanoparticle shape. Finally, understanding the nanoscale colloidal forces and geometric frustration between these new building blocks will enable the design of nanostructured solids made by out-of-equilibrium assembly. This research program will advance our fundamental knowledge on mechanics at the nanoscale and provide a mechanistic framework for synthetic chemistry of 2D materials. The nanoparticles that we will synthesize are expected to have broad applications due to their chiroptical properties and their stimuli responsive character in fields as diverse as nano-swimmers, detection of chiral bio-coumpounds, photo-catalysis, soft-robotic or sensors/actuators..

Very little is understood of the physics governing the Giant Impact and the subsequent formation of the Moon. […] We employ a multiscale approach to bridge the gap between atomic, geological sample, and planetary scales via thermodynamics […]. Plausible impact scenarios, features of the impactor and of the proto-Earth will be constrained with a feedback loop, until convergence between predictions of final Earth-Moon compositions and observations is reached.
