Confined fluids under time varying tribological conditions – Confluence
The objective of this project is to identify local phenomena occurring in a confined lubricated interface under time-varying experimental conditions such as fast change in relative velocities between bodies or oscillating motion, and to characterize lubrication mechanisms taking into account the con
Grain boundaries effects on hydrogen diffusion and trapping in fcc materials – CRISTALHYD
The scientific program of our project is divided into three main tasks. The first two ( Permeation / TDS and calculations at the atomic level ) concern the determination of local properties (diffusion and trapping) within the grain and neighborhoods of grain boundaries . The third task is the devel
Interface Stability Evaluation and Optimization for Organic Photovoltaic Devices – IN-STEP
In Organic Photovoltaic field, numerous laboratories are focuses on the first limiting point of the organic PV devices: the low power conversion efficiencies. To solve this issue, lots of efforts are put into the development of low-band gap polymers and optimization of the active layer morphology.
Slender structures: stability, optimisation, control – SLENDER
In this research, we will investigate and develop applications of multistable composite panels and shells as morphing surfaces capable of large shape changes under external loading and embedded actuation. This research topic implies the study of complex non linear phenomena that take place during l
Ultimate power multi-switching cells system integration in silicon multi-poles chip. – ConvPlUS
The project deals with the integration in the field of power electronics. It aims at developing new quasi-monolithic or monolithically integrated silicon power switching cells of higher performance and reliability. More precisely, The project aims to demonstrate through technological realisations tw
ELECtric field TailoRing of Organic-based Nano and micro-composite insulating materials – ELECTRON
Power electronics (PE) is the key technology to control the flow of electrical energy from the source to the load. New developments in PE allow the increase of the total power density of the conversion systems through the advances in: semiconductor technology (wide band-gap semiconductor), packaging
Crystal Nucleation On a Chip – CNOC
The combination of microfluidics and SAXS enables in-situ measurements, at the nanoscale, of structures involved during the nucleation process and reduces the limit of time resolution at the micro/milli second range (due the spatial-to-time conversion offered by microfluidic devices). The theoretica
New generation of all fiber optical amplifiers with erbium and gold – AMPEROR
The aim of this project (36 months), is to determine the feasibility of a new generation of optical amplifiers based on the realization of microstructured fibers containing nanostructures Au / Er 3+. This combination of nanostructures and microstructured fibers will be considered throughout this pro
Effects of climatic and mechanical variations on the durability of timber structures – CLIMBOIS
This project aims at investigating the durability of wood structures under variable climatic environment as well as several mechanical loadings. During these last years, two French laboratories LAMI (University Blaise Pascal) and GEMH (University of Limoges) conducted several studies to investigate
Electrokinetical transport in liquid foams – E-FOAM
This fundamental project is devoted to the study of electro-osmotic transport in a class of materials where it has never been explored: liquid foams. Though part of our daily lives and important in many industrial processes, foams are short-lived materials. Being strongly out of equilibrium, they
Shock-tube study at High-pressure of Oxygenated fuels for Chemical Kinetic – SHOCK
Auto-ignition is a fundamental process in combustion engines since it is the ignition process for Diesel engines and efficiency-restricting process for spark-ignition engines (knock onset). Therefore, auto-ignition is important for designers to predict and control for optimizing the desired performa
Efficient heat transfer in a regime of Elastic Turbulence – HotEt
The improvement of the heat transfer and heat-exchanger performance is the subject of much intensive research work. Improved heat-exchanger designs must satisfy several criteria: they should preferably be compact, should have high thermal efficiency with low pressure losses, and, for the chemical
Poroelastic couplings in artificial and real plant tissues – ARTIS
Plants are able to perceive mechanical-stimuli and adapt their development to mechanical perturbations such as wind, rain or obstacles - a crucial issue in this period of rapid environmental changes. This project aims at investigating the role of fluid mechanics and mechanics in this complex respons
Sea-ice Evolution in Arctic Summer – SEAS
The extent of sea ice during summer in the Arctic Ocean is among the most sensitive indicators of the ongoing climate change. The Arctic sea ice is known to have a key role in determining the planet albedo, which is the ratio of reflected over incoming solar radiation. During the last summer (2
Subwavelength PHOtonic CrYstals and Applications – Sphocya
In the last two decades, there has been huge efforts to create manmade materials with novel and engineered properties. The main goal of these researches consists in developing ways to manipulate, control or guide waves. This can consist in trapping waves in cavities, in forcing them to follow given
Fundamental studies on stratified mixing – STRATIMIX
Fluids with inhomogeneous temperature or chemical species concentrations are often encountered in geophysical and industrial flows. When those tracers modify the specific weight of the fluid, the setting of a stable density stratification is frequently observed. It is then natural to wonder how the
