News & Events

On the 4th of April 2019, Roger Lentle from Massey University (New Zealand) will give a seminar on the "Verifiable modelling of physical processing in the various compartments of the gut"

He will discuss the rheological and physiological difficulties in predicting mixing and propulsion of digesta within the intestinal lumen, and will also describe the use of spatiotemporal mapping to quantify movements in ex vivo segments of the intestinal wall in real time, the use of this data in computational fluid dynamic models to predict flow and mixing, and the concurrent use of dye marker excretion profiles to validate the models. Further he will give an example of how discrepancies between the two can highlight previously unknown sources of mixing. Finally he will discuss recent work on the stomach.

Roger Lentle is currently visiting researchers from the LRP to investigate the opportunity of coupling experimentations on the rheology of gastric fluids to his numerical approach.

The seminar will be held in the Nanobio Building at 2 pm.

The CERMAV, Grenoble's leading research center in glycosciences, is looking for a post-doc researcher to work within its "structure and properties of glycomaterials" team.

The project deals with the bulk production of cellulose oligomers with a controlled degree of polymerisation.

This one year position is opened to candidates with experience in material science, soft matter chemistry or physics, and with a good knowledge of X-ray or neutron diffraction analysis.

The project will be carried out in collaboration with researchers from the CERMAV, the LIPhy, the LGP2 and the FCBA.

Further to the 2018 call for research proposals, Tec21 will welcome two invited scientists in 2019.

Sami Boufi is a Professor at the Department of Chemistry of the University of Sfax (Tunisia) and develops his research activity in the field of biomass valorisation with a focus on nanocelluloses, their production, characterisation and use. He comes to Grenoble to work with Albert Magnin from the LRP and Julien Bras from the LGP2 on the production of high-consistency cellulose nanofibrils via twin screw extrusion. The aim is to be able to obtain highly concentrated suspensions of nanocelluloses without any concentration step required, therefore reducing the production costs, a key challenge in the industrial production of nanocellulose.

Dr. Madhav Ranganathan is associate professor at the Department of Chemistry of the IIT Kampur (India). He works on statistical and non-linear physics, crystal growth, biophysics and cellular motion, and comes to Grenoble to collaborate with Chaouqi Misbah from the LIPhy and Marc Leonetti from the LRP on the development of a computational model for the 3D simulation of the amoeboid swimming of cells. Besides the numerical developments, experimental investigations will be carried out to elucidate the importance of the cellular fluidity and the viscosity of the cell membrane on the mechanics of the motion.

The piece of artwork “Essere vento”, literally, “being the wind“, was revealed on the 4^th of December 2018 at the "laboratoire 3SR" in presence of the Italian sculptor Giuseppe Penone himself.

Giuseppe Penone likes to work with natural elements and materials, moulding them, sculpting them, and sometimes trying to reproduce the action of nature, as in his famous piece of work “Essere fiume”, for which he sculpted a rock just the way the river did it.

When they first met in 2015 in an exposition at the art museum of Grenoble, Giuseppe Penone asked the researchers if they would be able to sculpt a sand grain. “You bet!” was the answer.

Using high tech imaging tools, the researchers in close collaboration with the artist, carefully selected the grains that would serve as models, as well as those that would be eroded micron after micron, using LASER beam machining, to shape them like the models, as closely as possible. A number of pair grains were fabricated, and in honour of this collaboration with the researchers from the "laboratoire 3SR" specialising in the microstructure of geomaterials, Giuseppe Penone has chosen to include a pair of twin grains in a 50 kg piece of art made of moulded concrete. The sculpture was offered to the art museum of Grenoble and will be kept at 3SR for 3 years.

This work is the result of a collaboration between Giuseppe Penone, Joël Chevrier (Néel Institute), Cino Viggiani and Edward Andò (laboratoire 3SR), and the MUL company in Toulouse.

Jacky Mazars and Félix Darve are amongst the main contributors to civil engineering sciences and solid mechanics. In honour of their (solid and non-linear!) career, their colleagues from the 3SR lab have invited collaborators and friends to pay tribute to their work in a two-sessions conference, the one dealing with geomechanics, the other one dealing with the vulnerability of civil engineering structures. Both will most certainly appreciate such a nice present just before Christmas!

The conference will be held in the Kilian amphitheatre on the 11^th and the 12^th of December.

On the 24th of January 2019, the IRSTEA, the CEN and the ANENA organise a workshop on avalanches for high school students.

The researchers from Grenoble have long been involved in the study of avalanches, in particular in the modelling of snow as a granular material exhibiting a complex behaviour. This outreach day will consider the aspects in relation to risk and safety, avalanche prediction, protection infrastructures and the modelling of snow flows. In the afternoon, two parallel sessions will be held, the one dealing with the mechanical modelling of powder snow avalanches and dense snow avalanches, the other one dealing with climate change and the future of snow in ski resorts. During these sessions, the students will have the opportunity to interact with the speakers and ask their questions to researchers from the IRSTEA and the CEN (French Centre for Snow Studies).

Registrations are open until the 20th of December 2018.

The collaborative research platform PEI, dedicated to clean technologies and industrial processes, brings together students, researchers and industrials in an environment likely to favour the connexions between them.

The building was delivered in october 2015, and the platform was officially launched in July 2016 with the ambition of hosting education programmes, collaborative research projects, and startups.

After two years of efforts, PEI is now fully working, with almost 10 research projects in progress from 6 different laboratories on the campus, more than 100 hours of teaching at the master level for the past year, and since the beginning of 2018, 3 startups companies hosted, developing activities in industrial gas analysis, air purification, and the characterisation of complex fluid.
