Research Axes

The LabEx EMC3 was designed according to a scientific roadmap including 2 axes from the research fields of our member laboratories (Materials for Energy and Clean Combustion) and a third interdisciplinary axis initiating new collaborations between our members. This roadmap is managed by Serge Bouffard along the following lines:

LAN2600_webEnergy Materials

Given the many challenges related to materials for energy, research at LabEx EMC3 focuses on topics where its members have an international reputation, that includes thermoelectricity, meterials for light emission and materials for nuclear energy. The development of new non-polluting energy sources and saving fossiles fuels represent  a great challenge for researchers. The excellence of our laboratories is based on skills and expertise in the following types of materials: ther thermoelectric materials used in generators to convert heat into electricity, structural materials used in nuclear installations and in particular the aging process of those, the electroluminescent materials and to lower power consumption.

LAN0117_webClean Combustion:

Given the significant challenges related to energy production, research at LabEx EMC3 focuses on the burning of fossil and alternative fuels as well ason systems wih high energy efficiency and on pollution control and CO2 capture processes. Combustion remains one of the most serious problems in the production of energy for urban and industrial activities and for automotive and air transportation. Estimated energy consumption is expected to grow by more than 5% per year over the next 20 years. This will have a negative effect on oil resources and the environment with the increase in greenhouse effect and the degradation of air. Thus, progress on clean combustion is essential not only from an environmental point of view bus also to enable manufacturers to competitive players.

Our laboratories have considerable expertise in combustion and depollution, especially in digital simulation in automotive catalytic engine or in fluid physics. This research is organised into four themes:
• Turbulence and viscoelasticity: 

➢ Understanding of the mechanisms of scalar turbulence flows with free jets

➢ Viscoelasticity in flows
➢ Diphasic flows, atomisation and sprays 

• Catalytic convertors: understanding and improving catalysers for environment safety
➢ Operando studies
➢ Degradation of 
volatile organic compounds
➢ Plasma kinetic chemistry

• Reactive flows: optimisation of combustion systems and plasmas
➢ Combustion in energy production field, and air & ground propulsion to achieve better energy efficiency and environmental safety
➢ High-pressure combustion
➢ Plasmas (ignition, CO2 …) 

• Advanced numerical simulation: multi-scale approach turbulent flows, from atomisation simulation of fuel jet to deep description of chemical kinetics of combustion
➢ Development of supercomputing codes
➢ N
umerical simulation of complexe systems


Transdisciplinary Research LAN1176_web

The development of high-level instrumentation is essential to our laboratories. CIMAP and CORIA laboratories have complementary skills in laser design and  physics. Common research themes reinforce partnerships and the quality of future projects. LCS and CIMAP have convergent approaches on the use of IR spectroscopy to study operando catalysts or to track changes in irradiated materials. LCMT, CRISMAT & LCS have a shared interest on the synthesis, the characterisation and the packing of materials that are organic, inorganic or hybrid. These three laboratories have convergent approaches on analytical techniques for the characterisation at the molecular scale of innovative materials.
This axis is divided into 3 themes:

• Scientific instrumentation: experimental developments implying researchers
➢ Lasers
Operando in situ spectroscopy
➢ Real-time multiparamater acquisitions
➢ Materials synthesis and characterisation methods
➢ Optical and laser diagnoses of reactive flows
➢ Metrology in high-temperature environment

• Recovery and conversion of energy by high efficiency thermoelectric modules
➢ Integration of
thermoelectric modules on combustion systems, motors and/or exhaust lines
➢ Joint approach on thermodynamic modeling and 
experimental test bench measurement to optimise this technology
➢  Centimetric scale electricity
production system
➢ Heat recovery for electricity production
•  New materials synthesis: new hybrid (organic-inorganic) and nanocomposite materials with controlled properties for thermoelectric catalysis and optics
Clean process development
➢ Easy implementation
➢ Limitation of costs
