Welcome to the 

Nature Inspires Creativity Engineers Lab 

of IMREDD – University of Nice, France


Our laboratory is internationally known in the synthesis and development of organic and organic-inorganic hybrid materials. Our knowledge allows going from the molecular conception toward the construction of surface with specific properties in different fields: NanoTech, SmartTech, BioTech.

Highlight: Superpropulsion of Droplets and Soft Elastic Solids

We investigate the behavior of droplets and soft elastic objects propelled with a catapult. Experiments show that the ejection velocity depends on both the projectile deformation and the catapult acceleration dynamics. With a subtle matching given by a peculiar value of the projectile/catapult frequency ratio, a 250% kinetic energy gain is obtained as compared to the propulsion of a rigid projectile with the same engine. This superpropulsion has strong potentialities: actuation of droplets, sorting of objects according to their elastic properties, and energy saving for propulsion engines.
