SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Plasma flow reactor for functionalization of small organic molecule\n\n\nA presentation from Stéphanie Ognier (Chimie ParisTech – PSL)\n \n \nPlasma is a powerful technology for the generation of reactive species without any catalyst. It is currently used for the modification of materials in several areas of industry but underused in the field of small molecules due to the lack of accessible plasma reactor in liquid phase. The “Plasma\, Processes\, Microsystems” team (2PM)\, headed by Prof. M. Tatoulian\, has developed therefore since 2013 gas-liquid two-phase flows micro-structured reactors coupled to plasma devices able to generate in a controlled way gaseous reactive radical species in close contact to a flowing liquid phase. Preliminary results demonstrated the proof of concept with various types of cyclohexane and benzene functionalizations using different gases (O2\, H2\, NH3\, CO). Since then\, this unique association of plasma and microfluidics is studied to explore new functionnalizations\, such as acylation or methylation\, starting from various types of substrates. The presentation aims to show that plasma technology could open up new opportunities to functionalize organic molecules in a simple and effective way in metal-free conditions (no catalyst) at ambient temperature and pressure.\n\n \nHere is the zoom link: https://espci.zoom.us/j/88226705731?pwd=NTBTK2JhaHoxdE85VFlCbVo5ZUFSUT09

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Nanoscale Turing patterns in bismuth monolayer\n \nYuki Fuseya \nUniversity of Electro-Communications\, Tokyo\n \nOrdered patterns can arise out of randomness during morphogenesis. An explanation for this puzzle was put forward by Turing\, who explained the emergence of stational patterns by invoking the interplay between an activator and an inhibitor with different diffusion rates [1]. Turing’s theory of diffusion-reaction has proven to be highly influential across many disciplines. For example\, the pigment patterns on seashells\, stripes on tropical fish\, and the purely chemical system of chlorite-iodide-malonic acid have been studied as Turing patterns. The typical length scale for biological pigment-based patterns ranges from millimeters to centimeters\, and that for the purely chemical system is of the order of sub-millimeters. However\, Turing patterns below micrometers are extremely rare in nature and have not been examined in detail.\n \nHere we show that atomic monolayer bismuth grown on the surface of NbSe2 by molecular beam epitaxy (MBE) provides another opportunity in « hard » condensed matter [2]. We report evidence of a Turing pattern with a period of five atoms (approximately 2nm) that appears in a strained atomic bismuth monolayer assembling on the surface of NbSe2 subject to interatomic interactions and respective kinetics. We found stripe patterns and domain walls with Y-shaped junctions that bear a striking resemblance to what has been experimentally observed. This is the first demonstration of a Turing pattern at the atomic scale in hard condensed matter physics.\n \n[1] A. Turing\, Phil. Trans. R. Soc. Lond. B\, 237\, 37 (1952).\n[2] Y. Fuseya\, H.
