The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Researchers at the CEA-Irig have introduced a new catalysis tool for green chemistry, by creating crystalline artificial enzymes whose solid form increases stability and allows more reaction cycles under harsher conditions.

The PMIP (Paleoclimate Modelling Intercomparison Project) collaboration publishes the first results of its 4th "phase", for the study of the climates of the Middle Holocene (6,000 years ago) and the last interglacial (127,000 years ago). These periods are characterized by a greater than average seasonality in the northern hemisphere, which increases the amplitude of the seasonal cycle of boreal temperatures and strengthens the monsoons in the north.
Nearly 200 scientists from an international collaboration including CEA-Irfu have been involved in collecting, processing and assembling images of half of the sky to prepare the DESI observations from 2021 to 2026. Objective: To unveil the mystery of dark energy!
CEA-Irig researchers are identifying a catalyst to produce methane directly from CO2.
Using an approach combining experimentation, characterization and multi-scale modeling, researchers from Iramis and their partners from the Direction des énergies and Andra have studied the corrosion of glass and metal in particular conditions of radioactive waste storage.
The data collected in 2019 by the KATRIN collaboration, in which CEA-Irfu participates, had made it possible to constrain the mass of neutrinos in an unprecedented way, leading to the world best upper limit for direct measurements. Another analysis of these same data reveals that they do not contain the signature of a hypothetical sterile neutrino. The experiment will continue, with increasing sensitivity, until 2024.
According to a study carried out by scientists from the LSCE (CEA-CNRS-UVSQ), CNRS and the Muséum national d’histoire naturelle, an isotopic analysis of strontium reveals the Indian origin of archaeological cottons dating from the 2nd-3rd centuries, in southeastern Arabia.
Noting the inconsistencies in health policies aimed at combating COVID-19, a mathematician from the LSCE (CEA-CNRS-UVSQ) and his co-authors are calling attention to the poor quality of available data, as well as the intrinsic sensitivity of epidemiological models to these data. According to them, it is impossible to make predictions about the number of infections without a thorough understanding of the non-linearities underlying the dynamics of a “complex system”, such as an epidemic.
Researchers at the CEA-Irig and their partners have provided the first demonstration of the potential of “spin-torque nano-oscillators” for use in microwave spectrum analyzers. These ultrafast devices with their nanosecond-scale resolution are proving to perform very well.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
