In situ three-dimensional opto-acousto-optical imaging of materials transformations at nanoscale – I2T2M
In optically transparent materials, time-domain Brillouin scattering (TDBS) [1,2] provides imaging of material inhomogeneities traversed by acoustic pulse [Fig. (a)] with nano-scale spatial resolution along its path. The first experimental applications of this technique for depth profiling (with 30-
Characterization tool of the magnetic properties at the nanometric scale – CARAMEL
The AFM allows a control of the tip height and its displacement while the magnetic sensor integrated in the AFM tip measures the magnetic field at each position. This combination is the original part of this project which will lead to a new tool opening new perspectives for material characterization
Nanoscale thermal sensing using hybrid diamond sensors – THESEUS
The sensor will be based on a novel design of hybrid architecture, building on a transduction of temperature changes on magnetic changes probed by single electronic spins in a diamond. Ultimate performances will be achieved by capitalizing in an innovative manner on (i) the unique sensitivity of dia
In situ microviscosity measurements in complex systems by using molecular rotors. – MicroVISCOTOR
The general objective of the MICROVISCOTOR project is the development of a microfluidic device able to measure on-line and in real time the microrheology with a spatial and temporal resolution. The idea is to apply this device to the measurement of microviscosity in complex fluids. For this, this pr
HYBRID DYNAMIC STRUCTURES FOR OPTICAL-QUALITY SURFACES SHAPE CONTROL – LiveMetaOptics
The novelty is to replace classical rigid and heavy optical mirrors with “live” and light dynamic optoelectronic systems consisting of a thin optical fire-polished glass sheet actively “live” supported by many-degree-of-freedom force-actuators/sensors integrated and miniaturized via additive manufac
Spectral Superdiffusive Phonon Sensor – SPiDER-man
Three challenging tasks shall tackle several scientific issues, especially in the development and the calibration of the SPSS. Among them, there is the handling of a TDTR heterodyne device to work at frequencies up to 10 THz, where thermal wave propagation dominates, keeping low signal to noise rati
Odorant Binding Proteins-based biomimetic optical nose – OBP-optinose
Today, there is a growing demand for sensitive and selective detection of volatile organic compounds (VOCs) in various domains such as environment monitoring, public safety, quality control, non-invasive medical diagnostics. Traditional methods, though accurate and reliable, require expensive equipm
Ultracompact fiber X-ray detectors based on scintillators coupled to nano-optical antennas – NANOPTiX
NANOPT-X is a forefront program aimed at realizing a new generation of X-ray detectors of improved performances (high sensitivity, high resolution, faster response time) available in ultra-compact and flexible architectures compatible with endoscopy. The main objective of NANOPTiX is to miniatur
Measurement accuracy – case of mechanical properties of oxide nanoparticles – MACAO
The behavior of materials at the nanoscale is known to be different from the one observed for bulk material. Due to the nanometer size of the sample, it is nevertheless difficult to observe the mechanisms responsible for these differences, and to measure the differences of properties. This project w
Sampled-current voltammetry on an electrode array for metallic trace elements detection in water – EASCVsens
Metallic trace elements are pollutants that are present in water naturally or because of mining, agriculture and industry. They are toxic even at trace level and so reliable analytical methods able to measure them on site are necessary. The most conventional methods used to quantify them are relativ
Super-resolution imaging through scattering media – SpeckleSTED
In recent years, super-resolution fluorescence microscopies have largely contributed to the understanding of many biological processes occurring on a nanometric scale in living matter. However, biological tissues are turbid. Beyond 100 microns in depth, focused coherent beams are then degraded into
Advanced Laboratory X-ray Microtomography – ALXM
For more than 25 years, synchrotron X-ray microtomography, especially in phase contrast or diffraction mode, has enabled the 3D characterization at the micro-meter scale of crystalline and amorphous media, both heterogeneous and architectured. By the earlier 2000s, laboratory X-ray micrography, whic
