Nanomechanical damping via electron-assisted relaxation of two-level systems

Olivier Maillet, Dylan Cattiaux, Xin Zhou, Rasul R. Gazizulin, Olivier Bourgeois, Andrew D. Fefferman, Eddy Collin

We report on measurements of dissipation and frequency noise at millikelvin temperatures of nanomechanical devices covered with aluminum. A clear excess damping is observed after switching the metallic layer from superconducting to the normal state with a magnetic field. Beyond the standard model…

Progress in process development of La0.7Sr0.3MnO3 thin films for uncooled THz bolometers

Thomas Quinten, Yoann Lechaux, Victor Pierron, Chantal Gunther, Laurence Méchin, Jean-Francois Lampin, Marc Faucher, Benjamin Walter, Bruno Guillet

We present preliminary results of uncooled THz bolometers based on La 0.7 Sr 0.3 MnO 3 thin films on SrTiO3 buffered high resistivity silicon substrates. Fabrication improvements enable to obtain low contact resistance and the impedance measurements show that it is possible to minimize the…

High Throughput Characterization Methods at the Wafer Scale for Sputtered Films Used in Micro-Supercapacitors and Li-Ion Micro-Batteries

Pascal Roussel, Aiman Jrondi, Khac Huy Dinh, Bukola Jolayemi, Clément Leviel, Maxime Hallot, Christophe Lethien

The emergence of new miniaturized and autonomous electronic technologies leads to a request of efficient microdevices for energy storage. The development of thin film Li-ion micro-batteries or micro-supercapacitors is an interesting way to power connected sensors, as their manufacturing method is…

In-Depth Investigation of Manganese Dioxide as Pseudocapacitive Electrode in Lithium- and Sodium-Doped Ionic Liquids

Thibaud Guillemin, Camille Douard, Anthony Impellizzeri, Christopher Ewels, Bernard Humbert, Christophe Lethien, Scott Wilfred Donne, Jean Le Bideau, Thierry Brousse

We investigate the contribution of pseudocapacitance to the overall capacitance of MnO2 electrodes in pure and alkaline-doped ionic liquids via two spectroscopic methods: step potential electrochemical spectroscopy (SPECS) and in situ Raman spectroscopy. For both characterization methods, thin-film…

Pharmacological inhibitors of β-cell dysfunction and death as therapeutics for diabetes

Stéphane Dalle, Amar Abderrahmani, Eric Renard

More than 500 million adults suffer from diabetes worldwide, and this number is constantly increasing. Diabetes causes 5 million deaths per year and huge healthcare costs per year. β-cell death is the major cause of type 1 diabetes. β-cell secretory dysfunction plays a key role in the development…
