Semipermeable polymeric membranes that selectively allow the passage of negative ions (anions) play a key role in several important technologies including fuel cells. Neutron studies untangle the complex dynamics in an anion exchange membrane when employed in a fuel cell setting. Fuel cells genera…

Des chercheurs de l'Irig réalisent des études de diffusion des neutrons sur le pnicture de fer-nickel-arsenic, un matériau supraconducteur à des températures moins basses que celles classiquement rencontrées. Ils sont parvenus à sonder ce composé à l’échelle atomique et leurs résultats pourraient favoriser la proposition d'un mécanisme commun à tous les matériaux supraconducteurs.

The worst of COVID-19 may have past, but new viral variants keep showing up. Developing new drugs that remain potent against the emerging variants is essential to stopping the spread of the deadly disease and protecting human health.After more than two years of studying SARS-CoV-2—the virus that c…

Internationally, researchers are hunting for ways to transport information via magnetic waves instead of electronsScientists have now discovered a circular wave motion in skyrmions, bringing us closer to these new technologiesMnSi, initially from cosmic dust, was studied as the closest model for t…

New algorithm enables more efficient acquisition of high-value datasets.

The weakly coupled planes of Fe ions in the material are pushed closer together under extreme pressure. This results in metallisation but not the loss of all magnetic order as previous measurements have suggested. The lower pressure order is however replaced by a new short-range version. …

During the second reactor cycle in 2020, the ThALES team and SCI/CS at ILL in Grenoble, France commissioned and tested a self-learning algorithm developed by the CAMERA team at Lawrence Berkeley National Laboratory (Berkeley Lab). For the first time, an algorithm took control over the measurement process, without human intervention. Completely agnostic (that is, without any prior information on t…

August 2020Supercapacitors are up-and-coming, energy storage devices, often used to store energy from renewable energy sources like wind turbines where power is intermittent. They combine the best of batteries and traditional capacitors – like batteries, they are able to store lots of energy but a…

Direct observations of the structure and catalytic mechanism of a prototypical kinase enzyme will provide researchers and drug developers with significantly enhanced abilities to understand and treat fatal diseases and neurological disorders
