Materials day in Sophia Antipolis (09/2018)

Logo des JM UCA The partnership platform project for advanced characterization of materials by ACT-M electron microscopy (advanced characterization techniques for materials) includes 7 laboratories, including CRHEA, and 2 companies located in the perimeter of the Côte d'Azur University (UCA). In the framework of its mission of structuring the research on the Materials at UCA, ACT-M organizes the first UCA Materials Day on September 14th 2018.

Designing metalenses and metasurfaces of unusual shapes (08/2018)

Représetation schématique d'une métasurface CRHEA, in collaboration with the center of the CNRS International NTU THALES Research Alliance in Singapore, presents a method for designing ultrathin optical components - commonly called metasurfaces - of arbitrary shapes. The method relies on an optical transformation technique used in the field of metamaterials. With this results, it is now possible of predicting and designing the optical response of metasurfaces conformal to non-planar objects. This method would enable new design opportunities for free-form optics, illusion optics, radar and military camouflage. See the article...

Cathodoluminescence: a new look at the primitive objects of the solar system (07/2018)

Observation d'olivine en cathodoluminescence The understanding of the first stages of the formation of the solar system has always animated the community of physicists, astrophysicists and cosmochemists. In this research, the analysis of the main constituents of so-called primitive meteorites represents a major challenge in view of their potential role as witnesses to the mechanisms that occurred in the first 5 million years of the life of our solar system.
From then on, the pooling of multidisciplinary knowledge and know-how becomes a decisive asset. This is the case of a study conducted by a researcher and an engineer from the Lagrange Laboratory (CNRS-Nice Sophia Antipolis University UMR 7293 / Côte d'Azur Observatory, Nice), specialized in cosmochemistry, and the Research Center on Heteroepitaxy and its Applications (CNRS - UPR10 / University of the Côte d'Azur, Valbonne), specializing in the development of semiconductor materials. Thanks to the use of high sensitivity cathodoluminescence (CL), coupled with a field-effect scanning electron microscope, new internal structures have been observed in olivines (Mg2SiO4), one of the constituents of meteorites. This study makes it possible to highlight a mechanism of epitaxial growth of these objects at high temperature. The very high sensitivity acquired on the images of CL allowed this interpretation which is opposed to that commonly accepted in the community of cosmochemists. The study thus sheds new light on the formation of olivines as well as larger structures (the chondres) in which they are included, and allows them to be considered as local probes of the gaseous environment of the primordial protoplanetary disk.

Kleraria arrives in CRHEA (03/2018)

Klearia logo CRHEA and CNRS have signed an accommodation and collaboration agreement with Klearia, which has moved in CRHEA's laboratory since March 2018. Klearia is a spin-off from CNRS, that develops high value-added glass microfluidic devices also called “lab-on-a-chip” dedicated to researchers working in the field of flow chemical synthesis or analytical chemistry. This spin-off was previously housed in the Center for Nanosciences and Nanotechnologies in Marcoussis close to Paris. Klearia chose CRHEA for its environment and its technological platform of micro and nano-manufacturing CRHEATEC.
