Combination of Precipitation and grain Refinement for the Achievement of high Strength Aluminium alloys – PRASA
Aluminium alloys play an important role in the transportation industry. In the aircraft or the car industry, the demand for high strength alloy to design low weight structures is nowadays strongly driven by energy savings and low CO2 emissions. Thus developing, optimizing and producing new alloys wi
Transport and Adsorption in MultiScale Porous Materials – TAMTAM
Hierarchical porous materials, combining multiple porosities, are widely used in industry (adsorption, separation, catalysis) to overcome slow diffusion in microporous solids ( < 2 nm) and increase access to their large surface area. The benefits of combining porosities by adding meso (2-50 nm) and
Delay transition to turbulence by mimicking lotus leaves – DETAIL
The lotus leaf is known for its self-cleaning properties that are due to its high water repellence, also called superhydrophobicity (SH). This interesting property is due to the nanostructure of its surface, which is composed by a hierarchical structure of microepidermis covered in hairlike nanowaxe
Phonon heat transport in semiconductors containing mesoscale nano-inclusions – MESOPHON
The core of the project is the understanding of the fundamental processes occurring when a phonon of a given wavelength is scattered by a mesoscale-object having a size comparable to the phonon wavelength. This problem, which appears to be a classic case of electromagnetic wave physics known as the
The physics of multicellular organization in bacteria – BactPhys
We propose a novel approach to study bacterial multicellular organization based on physical mechanisms in order to identify the minimum elements of biochemical regulation required to coordinate complex processes such as bacterial clustering, stream formation, and fruiting body formation. This is a m
Sub-Riemannian Geometry and Interactions – SRGI
cf pdf cf pdf cf pdf cf pdf Sub-Riemannian manifolds provide an important mathematical model for many problems involving some nonholonomic constraints. Since several years, there has been an impressive revival of interest in sub-Riemannian geometry (in short, SR geometry), together with many emergin
Convergent Metrics for Digital Calculus – CoMeDiC
Discrete exterior calculus has emerged in the last decade as a powerful framework for solving discrete variational problems in image and geometry processing. It simplifies both the formulation of variational problems and their numerical resolution, and is able to extract global optima in many cases.
Nano-antenna arrays for next-generation solar cells – NANOCELL
Reducing the absorber thickness is one of the main issues for most photovoltaic technologies, because of the material cost or scarcity, and potential efficiency improvements with higher carrier concentration. Hence, highly efficient energy conversion in ultra-small volumes of semiconductors is a maj
Dynamic Constitutional Systems-toward selection of functions – DYNAFUN
The key objective of DYNAFUN is to provide a research programme with a deep knowledge and expertise on Dynamic Constitutional Systems, with new insights into the basic features that control multivalent recognition towards natural selection of functions. Research will be guided by the ambitious scien
Engineering Spins and Photons from Anisotropic DOts in Nanowires – ESPADON
Semiconductor quantum dots are promising building blocks for the development of future spintronics and photonics devices. The spin of a confined carrier can be used as a quantum bit, the recombination of electron-hole pairs provides triggered sources of single photons, confined carriers induce a fer
