La mutation de l’environnement et les enjeux du développement durable demandent à la société une adaptation constante.

Les technologies issues des sciences de l’ingénieur permettent le développement d’outils essentiels pour répondre aux défis des pays intertropicaux.

Le marché des sciences de l’ingénieur est extrêmement vaste et varié (capteurs, métrologie, matériaux) et reste très accessible dans les pays du Sud.

This invention combines water with a mixture of two or more salts which are excellent PCM Materials. The possible concentrations allow to achieve enthalpy values ranging from 200 to 500 kJ/kg, with intermediate properties adjustable to the targeted operating conditions. As well, their processing and use are carried out at atmospheric pressure & dissociation temperatures from -18°C to 35°C.

This innovation is related to a unique strategy to operate in a sustainable way a bio electrochemical system (BES) made of a bioanode coupled with a biocathode. This design opens up opportunities to produce, in an energy efficient way, organic molecules of interest such as biochemical and biofuels from biodegradable wastes.

This invention combines a specific device with a calculation method to determine the frictional characteristics between geotextiles and geomembranes surfaces G at the interface of a ground surfaces S. The measurements are performed on any geosynthetic materials and any “grounds” under both static & kinematic situations, using a tilted device. In the case of multilayer geosynthetics configurations, the weak sliding layer can be identified and its resistance can be quantified.
