The unique properties of supercritical fluids (SCFs) have been widely used since the 1980’sin a wide range of applications including separation, chemistry and...

In this thesis, we studied the transport of single fibers and suspensions of fibers in microfluidic geometries. This collaboration work between Schlumberger and...

Colloids - e.g. nanoparticles in solution - are objects that exhibit original optical properties. Their use as building block for fabrication of subwavelength optical...

In this PhD thesis, the nano-opto-mechanical system (NOMS) is explored and two nano-opto-mechanical devices are designed, analyzed, simulated and fabricated. Firstly,...

Microfluidics is a recent technology which one of the main advantages is the miniaturization of the studied phenomena, in any domain (energy, chemistry, biology...)....

This thesis aims at numerically simulating gas flows in porous matrices with micro-sized pores. We study the influence of hydrodynamic slip phenomena that appear when...

Vesicles are spherical lipid bilayers which enclose an internal volume, there are thus used in many applications such as encapsulation or design of biomimetic systems....

Microfluidics is a relatively new field, it really appeared in the early 90s. But this area has experienced strong growth and has reached maturity that allows it to...

The aging of our society leads to a development of neurodegenerative disease like Alzheimer's disease. Patients require an important caring by their family and...

This work presents the conception, characterization and use of a microfluidic microsystem dedicated to liquid metrology at THz frequencies. First part focuses on...

The interface man / machine had followed of many researches in biotechnology. A part of these researches concern the interconnections brain / machine. Indeed, the...

This work show the development of wireless passif temperature sensor based on the thermal expansion of a liquid in a micro-channel that modifies the electromagnetic...

We present here two microfluidic lab-on-chip devices based on self-organization of magnetic beads for biological analyses. The first one is dedicated to Circulating...

This work has been done in the context of fuel reprocessing in the nuclear industry. In fact, the handling of nuclear waste is one of the major issues in the nuclear...

To better understand enhanced oil recovery processes, we performed immiscible biphasic flows in microfluidic geometries, involving oil phases and aqueous phases. We...

In Alzheimer's disease, neurons die through a process of programmed cell death, called apoptosis. In vivo studies have shown that this stage of somatic destruction,...

We developed a novel microfluidic device in which magnetic particles are maintained dynamically in a microchamber and undergo hydrodynamic recirculation. From a...

Avec l'avènement de la microélectronique et des techniques de miniaturisation, de nouveaux domaines transdisciplinaires sont nés au confluent des sciences de...

The proliferation of user needs in the field of telecommunications, has led to overexploitation of the frequency spectrum. This led to the scarcity of frequency bands...
