Grenoble INP
Science and Engineery of Materials and Processes
< >

The laboratory is organised into five research groups concentrating on fundamental science in physics and physical chemistry, thermodynamics and kinetics, solid and fluid mechanics.
Research strategy, combining preparation - modelling - characterisation - usage properties is one of the strong points of the laboratory.
 

The fields studied concern nanosciences and materials for electronics, structural materials, solidification, materials for energy, divided materials, surfaces and interfaces and multiscale modelling.
It offers a wide range of high-temperature preparation processes (in particular electromagnetic processes) for solid or layered materials, based on gas-solid, liquid-solid and solid-solid methods, including the use of magnetic fields. Lastly, it offers facilities for multiscale analyses (modelling and characterisation) focusing on complementary scales from nanoscopic to microscopic, mesoscopic, process and reactor.

Cold crucible for nuclear waste vitrification

 Due to a collaboration between CEA-Marcoule and AREVA, this process reduces by a factor of 2-3 the volume of the technologic waste, thanks to the increase of the life of molten glass pots, moreover, by increasing the concentration of waste in the glass, it decreases approximately 25% of the volume of produced glass.

Topological optimization of architectured materials

 Finding the architecture that combines in the most efficient way a given set of conflicting properties is a key issue.  In such a context of material by design, we have developed a numerical approach based on topological optimization techniques.

Coherent X-ray diffraction by a Si single crystal surface

Using coherent X-ray scattering, we evidence atomic step roughness at the (111) vicinal surface of a silicon monocrystal of 0.05° miscut.  This experiment opens the way towards step dynamics on crystalline surfaces. (Scientific leader:Marc de Boissieu)

Throwing light on the undercooling puzzle

Simap-TOP-modelisation at the atom scale

Using ab initio molecular dynamics simulations, a new remarkable undercooling phenomenon has been explained namely an undercooling as deep as 350°C for Gold-Silicon eutectic alloy in contact with a specially decorated silicon (111) surface where the outermost layer of the solid featured pentagonal atomic arrangements.

Behavior of ferritic stainless steels stabilized during the annealing and pickling stages

 The metal/oxide interface of oxidized samples was three dimensional reconstructed using a scanning electron microscope coupled with a focused ion probe: MEB-FEG/FIB.
