ESPCI ParisTech is a chemistry and physics engineering college run by the city of Paris, France and a member of ParisTech . It conducts high level research in those fields.The students enter the School after a competitive examination following at least two years of Classes Préparatoires. They are called Pécéen or PC1 and Pécéenne or PCN. The School itself is also known as Physique-Chimie or simply PC.The ESPCI ParisTech is one of the founding members of ParisTech and a member of the IDEA League and the UNITECH International Society.ESPCI develops its relations with industrial partners such as Schlumberger, Rhodia, Total, Thales, Arkema, Michelin, which sponsored each yeargroup of students and signed research contracts with ESPCI laboratories. ESPCI ParisTech has signed partnership agreements with L'Oréal and Saint-Gobain for the recruitment of their professionals. Wikipedia.

The glass transition, extensively studied in dense fluids, polymers or colloids, corresponds to a marked evolution of equilibrium transport coefficients on a modest change of control parameter, such as temperature or pressure. A similar phenomenology is found in many systems evolving far from equilibrium, such as driven granular media, active and living matter. Although many theories compete to describe the glass transition at thermal equilibrium, very little is understood far from equilibrium. Here, we solve the dynamics of a specific, yet representative, class of glass models in the presence of non-thermal driving forces and energy dissipation, and show that a dynamic arrest can take place in these non-equilibrium conditions. Whereas the location of the transition depends on the specifics of the driving mechanisms, important features of the glassy dynamics are insensitive to details, suggesting that an effective thermal dynamics generically emerges at long timescales in non-equilibrium systems close to dynamic arrest. © 2013 Macmillan Publishers Limited.

Electrografting refers to the electrochemical reaction that permits organic layers to be attached to solid conducting substrates. This definition can be extended to reactions involving an electron transfer between the substrate to be modified and the reagent, but also to examples where a reducing or oxidizing reagent is added to produce the reactive species. These methods are interesting as they provide a real bond between the surface and the organic layer. Electrografting applies to a variety of substrates including carbon, metals and their oxides, but also dielectrics such as polymers. Since the 1980s several methods have been developed, either by reduction or oxidation, and some of them have reached an industrial stage. This critical review describes the methods that are used for electrografting, their mechanism, the formation and growth of the layers as well as their applications (742 references). © 2011 The Royal Society of Chemistry.

This review discusses how drops can levitate on a cushion of vapor when brought in contact with a hot solid. This is the so-called Leidenfrost phenomenon, a dynamical and transient effect, as vapor is injected below the liquid and pressed by the drop weight. The absence of solid/liquid contact provides unique mobility for the levitating liquid, contrasting with the usual situations in which contact lines induce adhesion and enhanced friction: hence a frictionless motion, and the possibility of bouncing after impact. All these characteristics can be combined to create devices in which self-propulsion is obtained, using asymmetric textures on the hot solid surface. Copyright © 2013 by Annual Reviews.
