Lithium-ion batteries’ energy-storing capacity can be boosted tenfold when the batteries’ electrodes are doped with silicon nanoparticles. Until now, the enhanced performance has only lasted a few cycles. This is because the electrode cannot withstand the tripling in volume the nanoparticles undergo during charging. Researchers at INAC and IMN Nantes recently maintained the doped performance […] >>

A new indoor-air-quality regulation will come into force in France on January 1, 2016. All buildings open to the public will have to prove that their indoor air contains less than 1 ppb of benzene. However, current portable testing systems are neither sensitive enough nor suitable for on-site testing. A research project backed by the […] >>

The geometry of gallium nitride (GaN) wires makes it tough to characterize a single wire’s electrical properties and n and p doping. Researchers from Leti and Institut Néel have found a solution. Using electronic lithography, the researchers connected a wire attached to an insulating substrate to four metal blocks and created a source of heat […] >>

To optimize the magnetic coupling in memory-type spintronic systems, the ferromagnetic (FM) and antiferromagnetic (AFM) parts must be very close to each other. Surprisingly, researchers at Spintec achieved a jump in performance by doing the opposite when they separated the FM and AFM parts with a diffusion barrier. Their unexpected results can be explained by […] >>

Researchers at Leti have developed a simulator to validate the position and size of the holes used to remove, via etching, the sacrificial material used to temporarily support structures during the fabrication of MEMS and NEMS—and release the systems’ moving parts. The holes substantially shorten a critical phase in the process of releasing moving parts, […] >>
