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.

SUMMARY:Seminar of Dr F. Maschietto (Yale)
DESCRIPTION:The seminar of Dr F. Maschietto (Yale) entitled : Signatures of environmental adaptation of allostery in protein homologues. \n \nFeel free to join on Teams here\n \n\nAbstract : Signatures of environmental adaptation of allostery in protein homologues.  \nAllosteric proteins exploit dynamics and conformational changes to effectively couple distant sites responsible for the initial activation and catalysis. To date\, research effort has routinely focused on studying ligand binding to the functional sites of proteins (active sites of enzymes)\, whereas the molecular mechanisms of allosteric regulation remains poorly understood. In particular\, little is known on wether proteins from different organisms\, absolving for the same function adapt their allosteric pathways and how. Therefore\, understanding how allosteric enzymes from different evolutionary paths achieve the same catalytic function remains a subject of great fundamental interest. Here\, we examine the allosteric pathways of the imidazole glycerol phosphate synthase (IGPS) enzymes from yeast and thermophilic bacteria by combining molecular dynamics simulations and network models derived from graph theory. We find rather distinct allosteric pathways in the two enzymes from different evolutionary paths although with the same function\, involving cooperative interactions between local and collective modes. Bacterial IGPS exhibits an allosteric mechanism that involves a hinge-like motion at the cyclase:glutaminase interface of the HisF and HisH enzyme subunits. In contrast\, IGPS from yeast exhibits a spring-like motion with protein expansion and contraction mediating a more direct and internal allosteric pathway. Remarkably\, the two rather different mechanisms accomplish the same function of activating the catalytic site upon effector binding to the allosteric site.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Teaching an old foam new tricks: material design\, memories and learning in aging solids\nDaniel Hexner \nDisordered solids are often out of equilibrium\, evolving slowly as they age. The small incremental changes inherent in the aging process reduce the internal stresses through microscopic plastic deformations within the material. While often considered as merely a nuisance and detrimental to reliable material design\, aging can\, in fact\, also be used as a tool to create novel functionality. Depending on the imposed deformation\, the system will evolve in different manners. By imposing various strain protocols\, we demonstrate that non-trivial elastic responses can be trained in a generic disordered solid. These include responses that are spatially dependent\, and highly nonlinear.  We argue that training can be considered a form of learning in materials\, and to that end we train a solid to classify high dimensional data that is inputted in form of imposed strains.\n\nOur approach for material design through training contrasts traditional approaches based on computer-aided optimization of the structure\, which is usually followed by careful fabrication. Functionality in our case is achieved from the self-organization of the large number of microscopic degrees of freedom\, rather than the difficult task of directly manipulating the microscopic structure.\n***********************\n\nhttps://us02web.zoom.us/j/83880710317?pwd=dVA5NHB6UXlTM3NsVWh2bzZTMHhEZz09\nID de réunion : 838 8071 0317\nCode secret : 692394
