SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:June 5 – 2 pm – Amphi Charpak\, ESPCI Paris-PSL. Bio-inspired Buoyant Gas Bubble-Encapsulating Microcapsules (GEMs)\, Daeyeon Lee Chemical and Biomolecular Engineering\, University of Pennsylvania\, Philadelphia\, USA. \nMany aquatic microorganisms\, such as cyanobacteria and green algae\, rely on intracellular gas vesicles—protein nanostructures with tunable collapse thresholds—to regulate buoyancy\, navigate light gradients\, and avoid predation. Similarly\, vascular plants use xylem cavitation as a water-stress response\, harnessing pressure-driven gas formation to regulate transport under extreme environmental conditions. Inspired by these strategies\, we have developed gas bubble-encapsulating microcapsules (GEMs)\, synthetic\, buoyant microcapsules\, via osmotic cavitation. I will discuss themechanics and kinetics of bubble growth. These GEMs represent a new class of soft matter systems that can be used for therapeutic delivery\, environmental sensing\, or materials actuation under mechanical load. Critical to understanding and optimizing the structure–function relationships in GEMs is the ability to generate large libraries of double emulsions with finely tunable diameter and shell thickness. To accelerate the discovery of GEMs and other cell-like droplet architectures\, we have developed an artificial intelligence (AI)-empowered Automated Droplet Library (ADLib) generator. This platform integrates a convolutional neural network-based object detection model with real-time feedback control\, enabling fully autonomous and rapid generation of droplet libraries. Capable of producing 25 distinct monodisperse double emulsions within 2–3 hours—down from a month of manual effort—ADLib monitors droplet morphology every 171 milliseconds and adjusts flow conditions with reaction times faster than those of humans. With a user-friendly graphical interface and robust hardware-software integration\, ADLib eliminates the need for constant operator oversight\, significantly increasing experimental throughput\, precision\, and reproducibility. By coupling bioinspired materials design with AI-enabled microfluidic control\, this work presents a promising pathway toward functional microstructures that actively respond to their mechanical environment\, much like their biological counterparts.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:June 6 – 10 am – Amphi Charpak Emulsion-Templated Synthesis of Functional Microcapsules Using Droplet Microfluidics Hyomin Lee Department of Chemical Engineering\, Pohang University of Science and Technology\, Pohang\, Korea.  \nMicrofluidically generated emulsions provide a powerful platform for the synthesis of structurally and compositionally tunable microcapsules\, offering advanced capabilities in the encapsulation\, retention\, and controlled release of functional materials. By precisely controlling multi-phase flows and fluid– fluid interfacial properties\, we exploit complex emulsions—particularly double and triple emulsions— as versatile templates for engineering novel microcapsule systems. In particular\, we develop fluorocarbon oil-based triple emulsions featuring an ultrathin intermediate layer that physically separates the inner cargo from the outer polymeric shell\, enabling high retention of challenging actives. Furthermore\, by harnessing electrostatic complexation between oppositely charged surfactants at the emulsion interfaces\, we demonstrate a robust and generalizable approach to stabilize these emulsions and expand microcapsule diversity without the need for intricate surfactant synthesis or spreading coefficient control. This platform allows for multiple solidification strategies— including polymerization\, freezing\, and solvent extraction—offering a true degree of freedom in capsule design for applications in drug delivery\, cosmetics\, and food. \nJune 6 – 10:35 am – Amphi Charpak Particle Adhesion on Thin Liquid Layer J. Parka\, C. S. Moona\, J. T. Phamb\, H.-J. Buttc\, and S. Wooha\na Department of Chemical Engineering Chung-Ang University\, Korea\nb Department of Chemical Engineering\, University of Cincinnati\, US\nc Max Planck Institute for Polymer Research\, Germany \nDust filters with small pores have been worldwide used to clean air and now are everywhere in our daily life. Dust\, also called particulate matter (PM)\, are captured at the pore of the filters\, therefore smaller pores result in higher PM capturing efficiency. However\, air becomes more difficult to pass through the filter as the pores get smaller\, which decreases the air permeability and increases the air pressure drop across the filter. This dilemma\, caused by the low adhesion of solid PMs to the dry solid surface of the filters\, has been one of the most important issue to be overcome on dry dust filter for several decades. Here\, inspired by human nose filtering system with thin mucus coated nasal hairs\, we create a dry dust filter having a thin non-volatile liquid layer at the surface of the pores. The strong adhesion of PM on liquid thin film improves the PM capturing efficiency without affecting the air permeability of the filter. The liquid thin film coated filter particularly exhibits outstanding dust filtering capability at fast speed filtering system with no re-dispersion of captured PMs. In addition\, the suppressed PMs re-dispersion allows a new bi-directional dust filtering. The Particle Removing Oil-coated Filter (PRO) filter proposes a new paradigm of dust filtering and opens a new door for fast and efficient air cleaning. \nJune 6 – 11:25 am – Amphi Charpak\, Protective Polymer Coatings on Silicon Anodes\, Gi-Ra Yi\, Department of Chemical Engineering\, Pohang University of Science and Technology\, Pohang\, Korea.  \nSilicon (Si) anodes are considered a promising next-generation high-capacity anode material due to their theoretical specific capacity of approximately 4\,200 mAh/g\, which is more than ten times that of conventional graphite. However\, their practical application is significantly hindered by a drastic volume expansion of up to 300% during lithiation and delithiation\, leading to severe structural instability\, rapid capacity fading\, and short cycle life. Furthermore\, Si-based anodes are known to exhibit poor thermal stability under high-temperature or high-rate cycling conditions\, making them susceptible to safety issues such as thermal runaway and fire hazards. To address these challenges\, surface coating technologies using polymer thin films have been developed to stabilize the Si particle surface. In particular\, chemically crosslinked polymer coatings have been introduced to enhance long- term cycling stability. This presentation will introduce the design and performance characteristics of Si nanoparticle-based anode materials coated with polymer thin films\, as well as a polymer gel electrolyte system developed in conjunction. Finally\, we will discuss an in-situ formation method for flame-retardant polymer coatings\, designed to mitigate abnormal temperature increases during abuse conditions. This approach aims to capture radicals generated by the breakdown of the solid electrolyte interphase (SEI)\, thereby improving battery safety under extreme conditions. \n1.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Dynamics of neuronal avalanches and other collective behavior  By Karin A. Dahmen\,. Department of Physics\, University of Illinois at Urbana Champaign\, at ESPCI\, Room Charpak\, entrance building\, ground floor. The tasks of neural computation are remarkably diverse. To function optimally\, neuronal networks have been hypothesized to operate near a nonequilibrium critical point. We use the framework of nonequilibrium phase transitions to describe the statistics and the dynamics of neuron avalanches in the brain. Measured scaling exponents\, exponent relations\, and scaling functions agree with the predictions of our models. We discuss connections to avalanches in materials\, including dynamical effects that can lead to unusually large avalanches\, and possible implications for the dynamics of the brain and other systems.Collaborators: Tyler Salners\, Karina E.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Alexandra Bridarolli (C2RMF\, Center for Research and Conservation of the French Museums) for a SIMM seminar this Thursday June 12 at 2 pm in Amphi Charpak. The title of Alexandra’s talk is « Climate and Collections: Impact of Climatic Variations on the Mechanical Behavior of Heritage Materials ». \nClimate and Collections: Impact of Climatic Variations on the Mechanical Behavior of Heritage Materials\n\nIn the current climate crisis and rising energy prices\, museums\, archives and heritage collections are facing the same challenges as the rest of society: rethinking conservation\, exhibition and storage practices and finding sustainable\, low-energy solutions\, while preserving the objects in their collections. At the heart of these reflections lie questions about collection climate. How can strict temperature and relative humidity (RH) conditions be relaxed to reduce the associated energy consumption\, while maintaining the physical integrity of the objects? It has become essential to understand the impact of these climatic parameters (RH and temperature) on the mechanical and physical properties of materials\, in order to accurately model the mechanical behavior of heritage objects and predict the risks of irreversible degradation (deformation\, cracks\, breakage\, etc.).\n\nTo illustrate this point\, this presentation will present two complementary studies: one conducted in the laboratory\, the other in situ.\n\nThe first study focuses on seven animal glues (from mammals and fish)\, widely used in the making and conservation of art objects as adhesives or binders for a variety of applications: gluing furniture joints\, preparatory coats for paintings\, paper restoration\, etc. Prepared in film form\, these adhesives were subjected to dynamic mechanical analysis\, carried out under variable humidity and temperature conditions. This method enabled the precise identification of the phase transitions specific to each adhesive\, as well as their phase-specific viscoelastic and fracture properties. The results obtained make it possible to predict their mechanical behavior as a function of the environment\, thus facilitating the choice of the most suitable adhesive from a mechanical point of view\, depending on the intended use.\n\nThe second study highlights situations in which direct measurement on the work is the only relevant method for addressing specific issues. It is based on acoustic emission measurements carried out on a wooden altarpiece\, with the aim of assessing its sensitivity to the museum climate. This non-destructive technique makes it possible to detect the formation or enlargement of micro-cracks within the work\, often before they are even visible to the naked eye.\n\nIn both cases\, the data collected provided tangible evidence to help heritage professionals make the right decisions in the face of climatic and energy challenges.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Universal Features of Emergent Electronic Fractals in Quantum Material by Erica W. Carlson\, Department of Physics and Astronomy\, Purdue University\, at ESPCI\, Room Charpak\, entrance building\, ground floor.  \nElectrons inside of many quantum materials spontaneously form clumpy patterns on multiple length scales. By importing techniques from disordered statistical mechanics into the field of quantum materials\, we have defined new conceptual frameworks for understanding and controlling this electronic inhomogeneity. This allows us to use the rich information available from spatially resolved probes to diagnose criticality from the spatial structure alone\, without the need of a sweep of temperature or external field. These new methods have enabled the discovery of universal\, fractal electronic textures across a variety of quantum materials. For instance\, scanning tunneling microscopy on BSCO reveals that the orientations of electronic stripes in that material form fractal\, self similar patterns displaying power law behavior throughout the superconducting doping range [1]\, leading to a connected scaffolding on which superconductivity can arise. Surprisingly similar structures are also found in antiferromagnetic domains in NdNiO3 and the Mott metal-insulator transition in VO2. In NdNiO3\, scanning resonant magnetic X-ray scattering reveals a highly textured magnetic fabric\, establishing a self-similar network of antiferromagnetic domains [2]. In VO2\, both scanning near-field optical microscopy and far-field optical microscopy have revealed that as opposed to transitioning from insulator to metal all at once\, VO2 forms an intricate\, fractal network of metallic puddles that extend like filigree over a wide range of temperatures [3]. This identification opens the door to using hysteresis effects to sculpt the filigree\, in order to improve the function of VO2 in novel electronic applications such as neuromorphic devices and quantum sensing. The universal features of these fractal electronic textures across a disparate collection of quantum materials hints at a common origin. We show that this emergent electronic complexity is the result of proximity to a critical point arising from the combined effects of quenched disorder and interactions. \n[1] Nature Commun. 14\, 2622 (2023).

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Pr Arvind Murugan from University of Chicago at CBI for a chaire Joliot. He will present his work below\, Wednesday 18th of June at 11h\, amphi CHARPAK:\n\nEvolution of error-correction through a need for speed. \n \nPhysicists have long seen life as a non-equilibrium process that fights the 2nd law of thermodynamics by maintaining order.  While we understand how extant biological Maxwell Demons work\, much less is known about how such Demons come into existence in the first place. Using theoretical and experimental work on the molecular machinery that copies DNA-based information\, we suggest that surprisingly little might be needed – proofreading mechanisms that maintain non-equilibrium order can potentially arise due to selection for faster replication\, even if the order itself is not beneficial in any way. We argue that evolution of error correction through a need for speed might also be relevant for any high-dimensional disordered process that creates a wide variance in the distribution of completion times such as self-assembly. Our work suggests the intriguing possibility that non-equilibrium order can arise more easily than assumed\, as a byproduct of fast self-replication\, even before that order is directly functional.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Engineering Nanocellulose Hydrogel Structure for BioMedical Applications Gil Garnier1\, Vikram Raghuwanshi1\, David Mendoza1\, Joel Hooper2\nGil.Garnier@Monash.edu \n1Department of Chemical and Biological Engineering and BioPRIA\, Monash University\, Clayton\, VIC\, Australia\n2School of Chemistry and BioPRIA\, Monash University\, Clayton\, VIC\, Australia Nanocellulose is the most abundant and cheapest family of organic nanoparticles. \nProf Gil Garnier from Monash University will visit the lab next Friday June 20. He will give a talk on « Engineering Nanocellulose Hydrogel Structure for BioMedical Applications » in amphi Boreau at 11h00\, ESPCI Paris-PSL.  \nAvailable at different length scales from the deconstruction of the plant cell wall\, some bacteria and micro- organisms\, nanocellulose is found as NanoCellulose Fibers (NCF)\, Cellulose NanoCrystals (CNC) and Bacterial Cellulose (BC). Hydrophilic and polar\, thanks to its 3 hydroxyl groups per glucoside monomers\, nanocellulose is easy to functionalize chemically. In water suspensions\, Nanocellulose forms systems ranging from random suspensions to functional gels and organized chiral nematic liquid crystal solutions. These different morphologies can be modulated with their stability\, engineered with the dimensions and charge of nanocellulose\, electrolyte addition and surface functionalization.\nIn this presentation\, we will first review technics to measure hydrogel structure and then relate the engineering of the gel structure to some applications. Chemical functionalization of the\nnanocellulose will be used to control gel structure. In the second part\, 2 types of examples using (nano)cellulose for biomedical applications. First we will present nanocellulose-based gels for\norganoids growth. Nanocellulose\, nanocellulose/collagen and thermosensitive NIPAM-graft- nanocellulose gel systems will be explored. Analysis will focus on the surface chemistry-property\nrelationship with a special emphasis on colloidal stability and gel structure. Second\, we will present paper diagnostic for blood analysis. The concept behing paper devices for blood typing\, fibrinogen detection and glucose measurement will be presented. Concepts of enzyme and antibody stabilization and paper diagnostic sustainability will be discussed. Our objective is to\npresent (nano)cellulose as a performant and versatile material easy to engineer into biomedical applications .

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Phonon mediated superconductivity in complex oxides\, By Julien Varignon\, Laboratoire CRISMAT\, CNRS UMR 6508\, ENSICAEN\, Caen.  \nSeveral oxides deriving from a Ruddlesden-Popper (RP) phase with the chemical formula An+1BnO3n+1 such as bismuthates BaBiO3 [1] and antimonates BaSbO3 [2] (n=∞)\, infinite layered nickelates R1-xAxNiO2 [3] (n=∞\, R=La\, Pr or Nd\, A=Ca or Sr) and Nd6Ni5O12 [4] (n=5)\, obtained after a chemical reduction of a parent RP phase\, or ruthenates Sr2RuO4 [5] (n=1) are superconductors either in bulk or once appropriately doped with holes or electrons. However\, the attractive interaction responsible of the Cooper pair formation at the core of superconductivity in these complex oxides is not yet fully understood and unified between compounds\, thereby hindering the identification of high critical temperature Tc superconductors whose record at ambient conditions is still held by cuprates.Using first-principles simulations performed with parameter free density functional theory (DFT)\, we reveal the existence of an insulating phase in the phase diagram in several of these complex oxides that is associated with a charge/orbital and bond ordered state. The electron-phonon coupling is then weakened by doping effects (or by other stimuli) so that the materials become metallic. Nevertheless\, we find that it remains sufficiently large to mediate the Cooper pairs formation with computed Tc’s in sharp agreement with experiments. These results suggest that the phonons responsible of insulating phases in complex oxides [6] may also be at the core of their superconducting state. Finally\, these results are ratified if all relevant degrees of freedom\, such as structural lowering events and local spin formation\, as well as an exchange-correlation functional sufficiently amending self-interaction errors inherent to practiced DFT are involved in the simulations. \nReferences:[1] Sleight\, Physica C 514\, 152 (2015).[2] Kim et al\, Nat.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Co-assembly of functionally active membrane proteins in mesostructured silica\, Brad Chmelka\, Department of Chemical Engineering\, University of California\, Santa Barbara. Thursday June 26 at 2 pm in Amphi Charpak\, ESPCI Paris-PSL.  \nThe physicochemical properties of membrane proteins\, such as for ion transport\, selective catalysis\, or biosensing\, are desirable for technological applications\, although they are challenging to harness in synthetic abiotic host materials. This is due\, in part\, to the challenges of incorporating relatively fragile protein molecules at sufficient concentrations in robust host environments in which the functionalities of the membrane proteins are retained. Nevertheless\, judicious selections of self-assembling surfactants\, solvent\, silica precursors\, and synthesis conditions enable high concentrations of functionally active membrane proteins to be stabilized in robust mesostructured inorganic-surfactant host matrices. Specifically\, light-activated proteorhodopsin\, a transmembrane protein that pumps H+ ions in green light\, has been incorporated at high loadings (>30 wt%) into transparent silica-surfactant films with high extents of mesostructural order. Small-angle X-ray scattering\, solid-state NMR\, and cryo-EM analyses yield detailed insights on the extent of mesoscale order and the nanoscale interactions of the protein\, surfactant\, and silica species in the hybrid materials. Transient UV−visible spectroscopy analyses show that the proteorhodopsin molecules exhibit native-like conformational dynamics\, as well as enhanced stability compared to surfactant or lipid environments. The results correlate the compositions\, structures\, dynamics\, and  properties of the proteorhodopsin molecules in mesostructured silica-surfactant host materials\, which have potential applications for solar-to-electrochemical energy conversion. \nJ.P.
