Gold nanoparticles, which are supposed to be stable in biological environments, can be degraded inside cells. This research conducted by teams from the CNRS, l'Université de Paris, Sorbonne Université, and l'Université de Strasbourg will be published in PNAS on December 16 2019, and reveals the ability of cells to metabolize gold, which is nevertheless not essential for their functioning.

'Results Hold promise for Fast, Accurate Single-Shot Readout 'Of Foundry-Compatible Si MOS Spin Qubits' 'SAN FRANCISCO ' Dec. 11, 2019 ' Leti, a technology research institute of CEA Tech, and its research partners have demonstrated a potentially scalable readout technique that could be fast enough for high-fidelity measurements in large arrays of quantum dots.

Publication by Laboratoire de physique in Physical Review Letters on August 30, 2019. We report the first quantitative measurements of the resonance frequencies of a torus of fluid confined in a horizontal Hele-Shaw cell. By using the unwetting property of a metal liquid, we are able to generate a stable torus of fluid with an arbitrary aspect ratio.

Evanescent Acoustic Beam Moves Suspended Particles at Lower Cost & Energy Consumption Than Existing Propagative Surface Acoustic Wave (SAW) Systems. CEA-Leti has developed a new acousto-microfluidic technology for manipulating microand nanoscale samples using evanescent sound waves. Described in a paper published in the September issue of Nature (Comm.

Project Combines CEA-Leti's Semiconductor Development Expertise and Silvaco's SPICE Simulation and Variability Analysis Technologies LAS VEGAS - June 3, 2019 - Leti, a research institute of CEA-Tech, and Silvaco Inc., a leading global provider of software, IP and services for designing chips and electronic systems for semiconductor companies, today announced, during the 56 th Design Automation Conference (DAC) in Las Vegas, a project to estimate and model the yield of ultra-low-voltage (ULV), ultra-low-leakage (ULL) static random access memory (SRAM) used in computing applications.

By studying the movement of runners at the start of marathons, researchers from the Laboratoire de physique (CNRS/ENS de Lyon/UCBL) have just shown that the collective movements of these crowds can be described as liquid flows. Their results, published in Science on January 4, 2019, have enabled them to predict how fluctuations in speed and density are transmitted through massive crowds.

REDFINCH Team Achieves These Capabilities in Mid-infrared Region, Where Many Important Chemical and Biological Species Have Strong Absorption Fingerprints GRENOBLE, France - March 19, 2019 - Leti, a research institute of CEA Tech, today announced prototype development of highly miniaturized, portable optical sensors for chemical detection of gas.

Leti, an institute of CEA-Tech, has developed a novel retinal-projection concept for augmented reality (AR) uses based on a combination of integrated optics and holography. The lens-free optical system uses disruptive technologies to overcome the limitations of existing AR glasses, such as limited field-of-view and bulky optical systems.

SAN FRANCISCO - Feb. CEA-Leti today announced it has prototyped a next-generation optical chemical sensor using mid-infrared silicon photonics that can be integrated in smartphones and other portable devices. Coin-size, On-chip Sensors that Combine High Performance and Low Power Consumption Presented in Paper at SPIE Photonics West 2019.
