A team of engineers and physicists at Southern University of Science and Technology, in China, has created a nickel-based material that behaves as a superconductor above the -233°C (40 K) threshold under ambient pressure. In their study published in Nature, the researchers synthesized thin films of bilayer nickelate (La₂.₈₅Pr₀.₁₅Ni₂O₇) and found one that behaved as […]

1,337 seconds: that was how long WEST, a tokamak run from the CEA Cadarache site in southern France and one of the EUROfusion consortium medium size Tokamak facilities, was able to maintain a plasma for on 12 February. This was a 25% improvement on the previous record time achieved with EAST, in China, a few […]

In a study published in Optics Express, a research group led by Prof. Fu Yuxi from Xi’an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences has developed the first room temperature holmium-doped yttrium lithium fluoride (Ho:YLF) composite thin disk laser, which can achieve high efficiency and quality continuous-wave laser output. […]

Scientists are racing to develop new materials for quantum technologies in computing and sensing for ultraprecise measurements. For these future technologies to transition from the laboratory to real-world applications, a much deeper understanding is needed of the behavior near surfaces, especially those at interfaces between materials.
