Durability of cement pastes exposed to external sulfate attack and leaching : Physical and chemical aspects

The unfortunate recent collapse of the Morandi bridge in Genoa has reminded us of the importance of the degradation of concrete and cement with time. For example, cement is attacked by sulfate (...)

Interplay between silicate and hydroxide ions during geopolymerization

Geopolymer is a low environmental impact binder obtained from clay or industrial by-products. However, to be a realistic competitor to the ordinary cement used in construction or nuclear waste (...)

Mechanics of elastomeric molecular composites

A classic paradigm of soft and extensible polymer materials is the difficulty of combining reversible elasticity with high fracture toughness, in particular for moduli above 1 MPa. Our recent (...)

Dual Marangoni effects and detection of traces of surfactants

In an article recently published in Soft Matter Journal, we report controlled and tunable Marangoni flows resulting from concentration gradients that are induced by placing a droplet of volatile (...)

Foaming of transient polymer hydrogels

Foams made with complex fluids enables to obtain a very good foam stability, however such foams are usually difficult to produce and process : entrapping air bubbles into viscoelastic materials (...)

Internal field 59Co NMR study of cobalt-iron nanoparticles

The catalytic growth of carbon nanotubes by catalytic carbon vapor deposition (CCVD) can be performed on variety of Co, Fe, and Ni catalysts. It is typically a three-step process where an (...)

Jeudi 31 janvier 2019 - 14h00 - Amphi Urbain

There is great interest to develop new materials with properties that resemble those of biological systems such as hierarchical organization, (...)

Dynamics of Active Particles

Cécile Cottin-Bizonne Institut Lumière Matière, Université C. Bernard, Lyon

Jeudi 14 février 2019 - 14h00- Amphi Holweck

The behavior of self-propelled particles, that are intrinsically out of equilibrium, is rather fascinating and opens new questions. Here we study (...)
