SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:And yet it clogs: flow (or no-flow) of suspensions in constricted channels\n\nAlban Sauret\, University of California Santa BarbaraAbstract:From pipes\, to highways\, to arteries\, stopping the flow is always inconvenient and sometimes dangerous. Clogging can occur whenever a suspension\, comprised of discrete particles dispersed in a liquid\, flows through a confined geometry. It is a major issue in many engineering systems\, such as additive manufacturing\, filters\, or in bioengineering. In this talk\, I will discuss the role of the different clogging mechanisms and our recent efforts to characterize and model the clogging of millifluid and microfluidic systems.I will first show that clogging by bridging of non-cohesive particles\, i.e.\, through the formation of a stable arch at a constriction\, is primarily controlled by the constriction width and the volume fraction of the suspension. Our experiments can be rationalized using a stochastic approach and provide guidelines to avoid clogging by bridging in constricted channels. In a second part\, I will report how pulsatile flows can help mitigate clogging when compared to steady flows in microfluidic systems. In this case\, the colloidal particles can attach to the wall and eventually leads to clogging. Yet\, by combining flow rate measurements with direct visualizations at the pore scale\, I will describe how pulsations can delay (or not) the clogging of the system.Even if clogging may always occur in a fluid system\, understanding the mechanisms and conditions of clog formation can lead to new design principles and to improve the reliability of many engineering systems.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Pr. Didier GOURIER\nChimie ParisTech\, PSL University\, CNRS\, IIRCP\, UMR8247\, 11 rue Pierre et Marie Curie\, 75005 Paris et Centre de Recherche et de Restauration des Musées de France C2RMF\, Palais du Louvre\n\n\n \n\nTitre:  « The proliferation of scientific misconducts: a plague for science and society in the 21st century »\n\n\nRésumé:\nOver the last few decades\, there has been a worrying increase in misconduct in the research community. They generally result in the retraction of articles\, because of falsified or even invented results\, methodological bias\, plagiarism\, etc… Disseminated and amplified by the media and social networks\, these misconducts have negative impacts on society (health for example) but also induce a loss of confidence of citizens towards scientific research and researchers.  Through some recent and even current examples this presentation shows the consequences of such misconducts in our society.

SUMMARY:Rentrée Climat
DESCRIPTION:C’est une première à Chimie ParisTech – PSL ! \nNous organisons la « Rentrée climat » pour nos élèves. Il y aura d’abord l’atelier de la Fresque du climat pour les 1A\, un atelier d’intelligence collective pour comprendre les liens de cause à effet entre énergie\, climat et biodiversité. L’atelier sera suivi d’une conférence « Etudiants\, Climat et Entreprises  » orientée vers les leviers d’action dans les entreprises\, en amphi Friedel ouverts à tous les étudiants et personnels de l’école. \nCet évènement est réservés aux étudiants de Chimie ParisTech – PSL. \n \n  \n
