Soft matter physics

Non-linear Physics: Dr. S. Dorbolo

nonlinearIt is so elegant to describe the Nature with the linear tool despite the fact that the beauty is located along the non-linear side of phenomena. Interconnection between bouncing, evaporation, granular material, fluid-structure interaction allows the uncovering of fascinating physics.

 

Biophotonics: Prof. L. Dreesen

biophotonicsInnovative optical biosensors, based on metallic or semiconducting nanoparticles, are developed and characterized using optical spectroscopies. Works are also devoted to potential applications of metallic nanoparticles for the production of singlet oxygen with possible applications in cancer photodynamic therapy. The membrane transport is also studied using optical techniques and artificial membranes build around optical fibers. Finally, optical non-linear properties of nanoparticles deposited on surfaces are analyzed as well as their coupling with biological species.

 

Experimental soft matter physics: Prof. G. Lumay

softphysThe behavior of fine powders and colloidal systems is directed by a wide range of physical interactions (electrostatic, hydrodynamic, capillary, magnetic, van der Waals forces and gravity). At the fundamental level, we are studying the link between these interactions playing a role at microscopic scale end the macroscopic properties of the material with a particular attention to the formation of mesoscopic structures. The experimental strategy is based on the development of original experimental set-ups. For some applications, these experimental set-ups can be used for the optimization of industrial processes.

 

Statistical Physics: Prof. N.Vandewalle

statphysThe interactions lying between microscopic agents are behind the complex behaviors observed at the level of groups. The study of fluctuations or dynamical cooperative phenomena are key methods for evidencing links between microscopic and macroscopic worlds. These methods applied to soft materials like grains, droplets or magnetic particles allow us to propose models for granular materials, bouncing droplets or self-assembled microrobots.
