Could all-natural materials be used to make antimicrobial dressings for open, infected wounds? A PhD research project conducted at CEA-Leti, CERMAV, and LGP2 investigated precisely this kind of environmentally-friendly dressing for inpatient care scenarios, and the findings were encouraging. The dressings studied here were made from nanocellulose obtained from wood. The material can take the […] >>

CEA-Leti and Irig are developing a mass spectrometry-based technique to “nanoweigh” viruses. And extremely accurate nanoresonators could expand the potential uses for the technique. CEA-Leti and Irig researchers were able to detect and weigh individual biological particles (from several megadaltons to a gigadalton). The technique was effective on bullet-shaped viruses like rabies and Ebola and […] >>

In research conducted for the EU Spice project, Spintec demonstrated an optical magnetic tunnel junction that is 1,000 times faster than magnetic tunnel junctions that use an electric write current. This breakthrough could lead to non-volatile MRAM with unprecedented levels of performance. Earlier in this project, Spintec had shown that a femtosecond laser could effectively […] >>

CEA-Leti has added even more new 300 mm equipment this year. The institute’s clean rooms can now fabricate their own low-resistance ohmic contacts—a BEOL process where the electrical junctions that link the active components of a circuit to the circuit’s connectors are made. The contacts fabricated at CEA-Leti offer resistances close to those made in […] >>

In research conducted for the EU Sinbat project, Irig is pulling out all the stops—electron microscopy, MRI, X-ray diffraction, synchrotron, and neutron scattering techniques—to characterize an innovative lithium-ion battery anode. The anode’s revolutionary composition includes active domains of amorphous silicon and FeSi2 nanoparticles in a graphite matrix. The silicon increases the anode’s capacity to incorporate […] >>
