As an alternative to the blast furnace, the current pig iron production reactor using fossil coal and coke and emitting huge CO2 amounts, we propose a novel, cleaner, direct reduction process using biomass (charcoal gasified in situ), able to cut down CO2 emissions by a factor 8.

Magnetron sputtering offers precise control over material properties, yet its potential on nanostructured substrates remains underexplored. We show that carbon nanomaterial substrates induce open microstructures that increase the active surface and enhance electrochemical performance. This scalable approach extends across multiple materials.

The original multidisciplinary approach described in this article, combining X-ray and electron diffraction, electron microscopy, and ab initio calculations, has successfully resolved the crystal structure of thin films of perovskite oxides. This work provides new insights for the vanadates and a methodology for determining precisely structural distortions for other heterostructures in general.

The Institut Jean Lamour is organizing a workshop on high-entropy alloys aimed at showcasing the breadth of research conducted at the institute on this new class of materials. In addition to presentations by IJL members, we will have the honor of welcoming Prof. Brian Cantor (University of Oxford and Brunel University) as well as Prof. Erik Lewin (Uppsala University).
The workshop will be held on February 25th at Amphitheater 200 (Campus Artem)

In 2019, the Nano-Bio-Materials for Life team was approached by the French Rowing Federation in Nancy to assist a world champion athlete suffering from motor disorders related to carpal tunnel syndrome. The team developed two grip solutions: one eliminating constraints on the affected part of the musculoskeletal chain, and the other alleviating them. Both solutions were patented in 2022 and 2025. This work subsequently led to the writing of this article.
This article explores the biomechanical consequences of using customized ergonomic equipment for each high-level single sculler on the water. It validates an ergonomic handle designed and manufactured in Nancy in the context of high-performance sports.

This publication marks the first contribution from the "Microstructures and Stresses" group within the framework of the DIAMS project (PEPR DIADEM). It demonstrates the feasibility of studying phase transformations in combinatorial metallurgy by leveraging the "process" parameters of the design space.
This result stems from a significant collaboration between IJL, SIMAP, LEM3, and ESRF, with whom the team is developing the Long Term Partnership "CombiMet."

In this study, we propose a new model-assisted method to design patterned membranes. This solution opens up new prospects for the design of customized membranes with technical specifications tailored to each patient.

Amorphous Sm–Ni–O nanoparticles produced by laser ablation were crystallized into the perovskite phase (SmNiO3) via in situ thermal treatments in the TEM. This study demonstrated that the initial Sm/Ni stoichiometry of the nanoparticles plays an important role during crystallization, as confirmed by analysis of high-resolution TEM images and by the increase in the Ni3+/Ni2+ ratio, a clear indicator of perovskite formation-measured by EELS.

Ce travail a pour objectif ultime de concevoir un dispositif capable de surveiller en temps réel l’endommagement d’une lime endodontique par analyse acoustique, afin d’alerter le chirurgien-dentiste en cas de risque imminent de rupture et de lui signaler la nécessité d’interrompre immédiatement son utilisation. Cette approche fondée sur l’émission acoustique est appliquée pour la première fois en endodontie. Cet article présente une première proposition de critère d’alarme acoustique.
