NanoSlim
The NanoSlim project (2018-2021) aims to design nanoparticles during the drawing of optical fibers. Centrale Nantes is involved in this project alongside six French laboratories.
The goal of the NanoSlim project it to develop fiber lasers and amplifiers with augmented and new properties. Such optical fibers rely on the doping of the fiber’s glass by luminescent ions, whose properties can be engineered through their encapsulation in particles of designed composition. However, the presence of nanoparticles induces light scattering that is detrimental for the guiding properties of optical fibers and imposes a need for size control of particles. In this context, the NanoSlim project aims to develop a new strategy to tailor nanoparticles, taking advantage of hydrodynamic effects during the drawing of the optical fibers.

Optiscan
OptiScan combines new machine learning techniques with ICI’s solid background on statistical shape modelling to reconstruct 3D objects from partial scans of their surface. Thanks to close collaboration with our partner company, STELIA Aerospace, software prototypes will be validated in an industrial environment using real data. The first tests on large fuselage panels have already been carried out, showing very promising results: scanning time could be reduced by more than 80%.

Calcium treatment
ICI is working with ArcelorMittal on the subject of calcium treatment of steel. In steel making process, the calcium treatment has the benefit of modifying the composition, shape and size of inclusions. However, it gives very irregular results in terms of calcium recovery. Even with many efforts done to understand the behavior of calcium in the liquid steel, it is not yet accurately predicted. Therefore, the mechanism by which the calcium droplets/bubbles dissolves into the melt and transforms the solid inclusions must be understood in order to optimize the process conditions. In order to identify the dissolution mechanism of calcium in liquid steel, mass transfer between the calcium droplets/bubbles and liquid steel needs to be predicted. Hence, the calcium/liquid steel interface must be accurately tracked. ICI-tech and its mesh adaptation features are used in this context.
