Asbestos: the size and shape of inhaled nanofibres could be exclusively responsible for the development of pulmonary fibrosis
Asbestos: the size and shape of inhaled nanofibres could be exclusively responsible for the development of pulmonary fibrosis
The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fibreglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. This was revealed by a study, published on 3 January 2024 in the journal Nature Nanotechnology , conducted on glass nanofibers by a French-Chinese team including a CNRS chemist.

CEA-Leti Proof of Concept Demonstrates Electrons Move Faster in Germanium Tin Than in Silicon or Germanium
CEA-Leti Proof of Concept Demonstrates Electrons Move Faster in Germanium Tin Than in Silicon or Germanium
Results Reported in Nature Article Suggest Vertical GeSn Transistors May Someday Enable Low-Power, High-Performance Chips and Quantum Computers C EA-Leti research scientists ha ve demonstrated that electrons and other charge carriers can move faster in germanium tin than in silicon or germanium, enabling lower operation voltages and smaller footprints in vertical than in planar devices.

Notre Dame: First Gothic cathedral to make massive use of iron
Notre Dame: First Gothic cathedral to make massive use of iron
Study of metal components from Notre Dame site. Cyril FRESILLON / IRAMAT / NIMBE / ArScAn / CEA / Chantier Scientifique Notre-Dame de Paris / French Ministry of Culture / CNRS Is Notre Dame the original Iron Lady? Evidence of the earliest known use of the metal for the construction of a Gothic cathedral has been uncovered by a team of scientists 1 working at the Notre Dame research site (CNRS / French Ministry of Culture).

A technology that 'sees' inside commercial batteries
A technology that ’sees’ inside commercial batteries
Controlling and studying the chemistry of batteries is crucial to improving their design. Scientists have developed an optical fibre based method for monitoring the evolving chemistry of a commercial battery in real time during charging and discharging. These results pave the way for easier and improved battery design.

Research Team Proposes New Approach for Next-Generation Memories with RRAM Energy-Storage Breakthrough
In-memory energy is a supplemental feature to in-memory computing, which is a key focus in CEA-Leti's roadmap. It can reduce energy use dramatically because RRAM-based batteries are highly scalable and dynamically allocable, and they can be placed next to memory blocks, which are near the processor. Locating the energy supply close to the processor is especially helpful when the processor requires peak power, which typically comes from an external source.

Neanderthals indeed painted Andalusia's Cueva de Ardales
Neanderthals indeed painted Andalusia’s Cueva de Ardales
The origin and date of appearance of prehistoric cave art are the subjects of ongoing debate. Spain's Cueva de Ardales is one point of discussion. There a flowstone formation is stained red in places. This colouring is apparently almost 65,000 years old 1 but until now, a part of the scientific community attributed it to a natural coating of iron oxide deposited by flowing water.

Africa's oldest human burial site uncovered
Africa’s oldest human burial site uncovered
The discovery of the earliest human burial site yet found in Africa, by an international team including several CNRS researchers 1 , has just been announced in the journal Nature . At Panga ya Saidi, in Kenya, north of Mombasa, the body of a three-year-old, dubbed Mtoto (Swahili for 'child') by the researchers, was deposited and buried in an excavated pit approximately 78,000 years ago.

High-temperature, low carbon processes: the challenge for the new Canopée laboratory
High-temperature, low carbon processes: the challenge for the new Canopée laboratory
The CNRS, l'Université de Lorraine and Saint-Gobain Group signed, this Friday, October 23, 2020, the creation of the Canopée laboratory, dedicated to the study of materials and "systems" under extreme temperature conditions. The objective is to reduce the carbon footprint of high-temperature manufacturing processes.

Turbocharged supercapacitors from new ionic liquids
Publication by Laboratoire de chimie, , on August 2019. A new article describes the discovery of a new class of electrolytes, which can improve energy storage efficiency in supercapacitors. A team of scientists from US, France, UK and Australia has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of ionic liquids based on common, non-toxic chemicals.
