The recently launched EU-funded project GAIN4CROPS aims to improve photosynthetic efficiency of the oil crop sunflower using nature-inspired solutions and innovative breeding techniques. The 5-year 8M € project, funded under the EU Horizon 2020 Framework Programme, will pave the way for the introduction of strategic crops which might decrease the use of major resources in agriculture: land, nitrogen, and water.
In order to improve lithium-ion batteries, IRIG researchers are replacing the graphite of the negative electrode with silicon-based materials that can store much more lithium. These new nano-architected composite materials are made up of active domains of Si-amorphous and crystalline FeSi2 nanoparticles dispersed in a graphite matrix. They are studying the ageing phenomenon of these anodes capable of withstanding 700 cycles with a capacity of nearly 70%.
Researchers at the IBS (CEA-Irig) have revealed a previously unknown mechanism for the proliferation of SARS-CoV-2, in which the virus uses immune cells to enhance its own capture and transmission!
Researchers from IRIG [collaboration] publish their solution to create an interface between two crystals without generating dislocations, even though their mesh parameters differ by several percent. This work opens up new possibilities for integrated optoelectronics and photonics on silicon.
This summer, after being shut down for 20 months, the ESRF (European Synchrotron Radiation Facility) has once again opened its doors to scientists, boasting an X-ray source that is one hundred times more brilliant than before (the EBS, Extremely Brilliant Source). Researchers at the Interdisciplinary Research Institute of Grenoble (CEA-IRIG) are involved in designing new experiments using the new beamlines, which are smaller, more brilliant and more coherent.
Researchers at the CEA-Irig have developed a new concept in nanomaterials involving an assembly of silver nanoparticles linked by a bio-inspired molecule.
On August 19, 2020, the European consortium SpinTronicFactory, led by the French laboratories[1] Spintec (CEA, CNRS, Université Grenoble Alpes) and Thales-CNRS Joint Unit (Palaiseau), published an ambitious spintronics road map in Nature Electronics. The field, at the frontier between magnetism and microelectronics, is coming of age, and offers wide possibilities for innovation.
A bacterium present in our intestinal macrobiota produces a particularly interesting antibiotic: Ruminococcin C1. Explanations from CEA-Irig.
Researchers at CEA-IRIG have used NMR to reveal the molecular mechanisms that support the adaptation of avian influenza virus from birds to humans. By uncovering the secrets of the interactions between the mutated viral polymerase and a key transcription factor in host cells, this new insight will make it possible to study the mechanism of cross-species contagion of these viruses and thus open up potential new therapeutic avenues.
A CEA team, in collaboration with the Pablo de Olavide University (Seville, Spain) and the Swiss company Solaronix, has invented a new family of photochromic dyes for photovoltaics. The result of this work paves the way for photovoltaic glasses whose transparency adapts to the luminosity, an interesting application in particular in the buildings and automotive sectors.
The CEA-Irig (IBS) has reported in Nature Catalysis a review on SAM proteins, a type of catalyst that produces highly reactive radical species.
At a time when mercury is becoming a highly toxic material for the nervous system, researchers at the Irig [collaboration] are making significant progress towards efficient, mercury-free, deep-ultraviolet light-emitting diodes used in water and air treatment, disinfection, counterfeit detection, etc...
To be or not to be expressed? Researchers at the CEA-Irig (IBS) are showing with precision how a bacterial metalloprotein controls the expression of certain genes. And all it takes is an electron and a proton!
Researchers from the CEA-Irig and the “Unité mixte de physique” CNRS-Thales have proposed a new spintronic approach based on ferroelectricity. For the first time, this approach allows spin currents to be manipulated using non-magnetic interfaces controlled by electric fields. The result: the electrical consumption of non-volatile spintronic devices can potentially be reduced by a factor of one thousand!
Researchers at the CEA-Irig have elucidated the activation cascade of one of the four Bacillus thuringiensis toxins that specifically target mosquito larvae, in order to prevent them from becoming vectors of devastating diseases.
Cern turned to the expertise of the DSBT to create a heat exchanger for the HL-LHC collider. This exchanger represents a technical feat in terms of compactness and performance, leading the CERN to commission the DSBT to carry out optimization, industrialization and cold tests with a view to installing exchangers in the superconducting magnets and then in the LHC tunnel by 2022.
IBS researchers and their partners have discovered a new weapon in the Pseudomonas aeruginosa arsenal.
Researchers at the CEA’s BIG Institute have shown how floral stem cells differentiate to form a flower, through an epigenetic regulation that could upset the canonical models.
Several nuclear magnetic resonance (NMR) techniques have enabled chemists from the Inac to elucidate the surface state of ternary chalcogenide nanocrystals (CuInS2) dispersed in an organic solvent. This is a key step in providing these nano-objects with new functionalities for energy conversion, photonics and biological analysis.
Researchers from the IBS have shown how bacteria converse within floating biofilms. The proteins involved in this interaction could be new targets in the fight against antibiotic resistance and nosocomial infections.
Thanks to progress in lithography techniques, new so-called “lateral” architectures are emerging in spintronics. Far more versatile and just as powerful as the current devices, they are opening up important prospects for memory and logic applications. It’s time to get creative!
When exposed to low-energy ultraviolet radiation, the extremities of chromosomes (or telomeres) can produce radicals that cause oxidative damage. A detailed study using time-resolved spectroscopy conducted at the Iramis reveals the mechanisms associated with these processes.
Les propriétés magnétiques et électriques des jonctions tunnel magnétiques ont pu être améliorées significativement en insérant des couches de métal réfractaire (tungstène) dans les empilements. Cette avancée ouvre de belles perspectives aux mémoires magnétiques MRAM composées de telles jonctions et qui rentrent en production de volume.
Scientists have performed a thorough analysis of promising silicon-based electrode technology with regard to Li-ion battery decay in the course of charge/discharge cycles. Oversaw by the CEA, this project was carried out through a balanced partnership between three academic and as many industry partners.
Using optical rather than electrical technology to write to MRAM magnetic storage media would unlock a thousandfold speed increase and slash power consumption by a factor of 100. Spice aims to tackle this challenge and promote the use of non-volatile memory near processor cores. A computing revolution in perspective...
A team from the BIG Institute has just demonstrated that uranium is not necessarily toxic to plants.
The hypothesis of a smallpox re-emergence cannot be ruled out. Researchers from the IBS are working on its cousin, vaccinia.
A team from the IBS has shown how some antibiotics become insensitive to the principal mechanisms of bacterial resistance.
