Researchers from INAC and Liten achieved a 30% increase in the current produced by an equivalent surface of platinum when they replaced a fuel-cell’s usual platinum-coated carbon electrode with a carpet made by bonding platinum nanotubes to the proton-exchange membrane. The structure, made using CVD, is covered with a fine layer of proton-conducting polymer. The […] >>

LMGP is pleased to be hosting Hironori Yamazoe, a researcher from the University of Tsukuba on sabbatical in Grenoble since mid-March. Yamazoe is an expert in microtechniques used to selectively deposit proteins on biomaterials—a process that could be used to build musculoskeletal tissue. And on July 1st, the University of Illinois at Urbana-Champaign’s Amy Wagoner-Johnson […] >>

That an electrical field induces deformation in piezoelectric materials is well known—and the opposite is also true. However, the mechanisms underlying this deformation remain unexplained. Researchers at Leti have just characterized the mechanism for lead zirconate titanate (PZT) thin films. They took in operando measurements using the Nanocharacterization Platform’s X-ray diffraction equipment, which is suitable […] >>

Spintronics usually uses ferromagnetic materials to achieve net spin polarization of an electric current. INAC researchers recently used a Rashba magnetic field to do the opposite. They used the field to recover spin information electrically at the interface between two non-magnetic thin-layer materials, bismuth and silver. This basic mechanism could now be used to produce […] >>

Leti, working under the EU SPADnet project, assembled and characterized a gamma sensor for positron emission tomography (PET). Unlike photomultiplier tubes, the gamma sensor is compatible with the intense magnetic fields of magnetic resonance imaging (MRI). The development could result in combined PET-MRI scans for cancer patients, providing the functional information of a PET scan […] >>
