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.

Paris, 9 January 2017 To paint quickly while creating exceptional texture and volume effects, J. M. W. Turner and other English artists of his generation relied on the development of innovative gels. All the rage in the 19th century—and still in use today—these compounds alter the properties of the oil paints they are combined with.

Paris, 29 November 2018 Scientists have revealed, for the first time outside our Galaxy, the properties of rapidly moving gas clouds in the immediate vicinity of a super-massive black hole, enabling the mass of the black hole to be measured with unprecedented accuracy.

Publication from the Chemistry laboratory in the Chemical Sciences journal on September 18, 2018. Abstract: The intrinsic photostability of nucleic acids is intimately related to evolution of life, while its understanding at the molecular and electronic levels remains a challenge for modern science.

Parker Solar Probe will soon become the spacecraft to travel the closest to the Sun, by positioning itself a little over 6 million kilometers from our star's surface. During its journey within the solar corona, the NASA probe will notably have an on-board instrument developed by researchers from the CNRS, université d'Orléans, and the CNES.

Observations made with the Very Large Telescope (VLT) of the European Southern Observatory (ESO) have, for the first time, detected the effects of general relativity predicted by Einstein, in the movement of a star passing into the intense gravitational field of Sagittarius A * , a massive black hole at the centre of the Milky Way.

In 2013, ESA's Planck mission unveiled a new image of the cosmos: an all-sky survey of the microwave radiation produced at the beginning of the Universe. This first light emitted by the Universe provides a wealth of information about its content, its rate of expansion, and the primordial fluctuations in density that were the precursors of the galaxies.

French researchers and Japanese engineers have joined forces to develop a new electron microscope that can scan the properties of matter on very small scales of time and space. The Centre d'élaboration de matériaux et d'études structurales (CEMES) of the CNRS and the Hitachi High Technologies Corporation (HHT) will formalize the creation of a joint laboratory on July 2, 2018, the first between the CNRS and a foreign company.

SPIRou, the new planet-hunting spectropolarimeter developed for the Canada-France-Hawaii Telescope (CFHT), has successfully recorded its first starlight. Ten years after it was first designed and following four intensive months of installation at CFHT, this international instrument in which France has played a leading role is on the point of initiating its scientific operations, namely the detection of exoplanets around nearby red dwarf stars and the study of newborn stars and planets.

Using a new computer model, researchers at the Ecole Centrale de Marseille and CNRS have shown that a fish expends less energy when it swims in a school, because neighbouring fish produce a 'suction' effect. This work will be published on 11 May 2018 in Physical Review Letters . Schools of fish provide a fascinating example of collective behaviour in which the group moves in a coordinated manner without the need for a leader.

Quantum chance is intrinsically different than classic chance. That is what the violations of Bell inequalities, a crucial step in understanding quantum mechanics, states. One drawback remains though: until now, testing these inequalities relied on experimental configurations that use parameters set from data generated by quantum systems.

Mimicking photosynthesis in plants, using light to convert stable and abundant molecules like water and CO2 into a high energy fuel (hydrogen) or into chemicals of industrial interest, is a major research challenge today.

The European Research Council (ERC) has announced the recipients of its 2017 Advanced Grants, awarded to experienced male and female researchers well known in their fields.

The HESS international collaboration, to which CNRS and CEA contribute, has published the results of fifteen years of gamma ray observations of the Milky Way. Its telescopes installed in Namibia have studied populations of pulsar wind nebulae and supernova remnants, as well as microquasars, never before detected in gamma rays.
