The importance of fine characterization techniques in laboratories specializing in the study of the physical, mechanical or chemical properties of materials in general is well established. Whether for understanding microstructure/property relationships, developing new materials or analyzing synthesis or implementation processes, it is essential to have high-performance analysis tools on a wide range of scales, from the micron to the atomic scale.

Le projet MANIOC vise un rayonnement international sur les matériaux durables grâce à la collaboration entre l’INSA-Lyon et deux partenaires de renommée mondiale en Allemagne

et aux Etats-Unis. Les recherches qui y sont associées concernent l’utilisation de l’hyperthermie magnétique en science et ingénierie des polymères permettant de mettre

au point des matériaux guérissables et adaptatifs.

Le projet X-LOSM a pour objectif la production de nouveaux miroirs diélectriques à très faibles pertes optiques en vue de leur utilisation dans des expériences de pointe employant des cavités Fabry-Pérot.

This project aims at establishing post-processing methods for a better understanding of the mechanical and anisotropic fracture behavior of nacre-like ceramic composites. These methods will couple two full-field measurement approaches, namely Raman spectroscopy for local stress field measurement and digital image correlation (DIC) for local strain field measurement. This coupling will be set-up during in situ mechanical testing.

As the world fights to tackle climate change, securing affordable, net-zero energy stands out as a paramount engineering task for ensuring a future for our and next generations. Among the pivotal technologies necessary to direct energy systems toward sustainability and net-zero emissions is Carbon Capture and Storage (CCS). CCS comprises several technologies which involve capturing CO2 from major point sources, followed by compression and transportation to appropriate underground reservoirs for either sequestration or enhanced oil recovery.

L’objectif est de développer une solution française de fabrication d’outils en carbure de tungstène par fabrication additive (Binder Jetting) servant des industries de pointe telles que l’aéronautique, l’automobile, l’énergie, le naval ou encore l’armement. La chaine de valeur sera abordée dans son ensemble : de la poudre à la pièce. Des retombées sociétales fortes sont attendues avec le développement des compétences et des emplois, et l’économie d’énergie et des ressources de matériaux rares.

Ce projet a été financé par l’État dans le cadre de France 2030.

Aluminum alloys are used extensively in aircraft due to their high strength-to-weight ratio. A main drawback is that their microstructure is sensitive to corrosion, which generates pits for example. Although corrosion damage can be detected by non-destructive testing methods, such methods are limited in their ability to identify corrosion initiation and the mechanism behind the defect. As a result, corrective actions are only undertaken when corrosion becomes evident (cracks or loss of thickness).

Since the emergence of nanotechnology in the 80s, block copolymers are frequently used to design "preforms" to control the structure of inorganic nanoparticles. MANIOC's philosophy is based on the opposite reasoning. It consists in manipulating the microstructure of triblock copolymers by selectively adsorbing their ends on the surface of “stimulable” and “guidable” magnetic particles. The experimental process, allowing the design of non-equilibrium microstructures on demand, can be summarized in three steps:
