Abstract:
Neutron scattering had its origin in 1932, the year that marked the discovery of the neutron by Chadwick, and the first nuclear reactors were successfully operated in Chicago and Oak Ridge, Tenn., in the early 1940s. During its initial stages, neutron scattering was used mainly for the study of “hard” crystalline materials. For example, Shull and Wollan's pioneering research, which led to the 1994 Nobel Prize in physics, began with studies of iron, chromium, and iridium, and was followed by the development of polarization analysis to determine the structure of magnetic materials. Such studies continue to yield important structural information (see the articles on magnetism by Aeppli and Hayden and on crystallography by Radaelli and Jorgensen in this issue of MRS Bulletin), although during the last two decades, the technique has been increasingly used by scientists from other disciplines (chemistry, biology, polymer science), and many of these newer applications have involved “soft” matter such as polymers, colloids, and gels. By definition, these substances are “plastic” or “squishy,” and easy to mold into different shapes; because of this flexibility, they have become some of the most practical and widely used materials today.

Abstract:
The cytoskeleton provides eukaryotic cells with mechanical support and helps them to perform their biological functions. It is predominantly composed of a network of semiflexible polar protein filaments. In addition, there are many accessory proteins that bind to these filaments, regulate their assembly, link them to organelles and provide the motors that either move the organelles along the filaments or move the filaments themselves. A natural approach to such a multiple particle system is the study of its collective excitations. I review some recent work on the theoretical description of the emergence of a number of particular collective motile behaviours from the interactions between different elements of the cytoskeleton. In order to do this, close analogies have been made to the study of driven soft condensed matter systems. However, it emerges naturally that a description of these soft active motile systems gives rise to new types of collective phenomena not seen in conventional soft systems. I discuss the implications of these results and perspectives for the future.

Abstract:
To obtain high ambient ionic conductivity of solid polymer electrolyte (SPE), we introduce polymer-in-salt system with ion hopping mechanism contrary to traditional salt-in-polymer system with segmental motion mechanism. In polymer-in-salt system, the interaction between polymer and salt is important because polymer-in-salt electrolyte contains a large amount of salt. Thus, we try to solve the origin of interaction between polymer and salt by using hard/soft acid base (HSAB) principle. The SPEs are made up of two types of polymers (poly(ethylene oxide) (PEO, hard base) and poly(ethylene imine) (PEI, softer base than PEO)) and four types of salts ( LiCF 3 SO 3 (hard cation/hard anion), LiCl (hard cation/soft anion), AgCF 3 SO 3 (soft cation/hard anion), and AgCl (soft cation/soft anion)) according to HSAB principle. In salt-in-polymer system, ionic conductivities of SPEs were affected by HSAB principle but in polymer-in-salt system, they were influenced by the ion hopping property of salt rather than the solubility of polymer for salt according to HSAB principle. The highest ionic conductivities of PEO-based and PEI-based SPEs were 5.13 × 10-4Scm-1 and 7.32 × 10-4Scm-1 in polymer-in-salt system, respectively.

Abstract:
Like The Magic Flute, my career has been paved by wonderful and unexpected stories played by enthusiastic and talented students, in close contact with experiments and industry. I participated in the birth of soft matter physics under the impulse of Pierre-Gilles de Gennes: polymers, liquid crystals, colloids, and wetting, which I later applied to the study of living matter. By teaching in the early days at the Institut Universitaire de Technologies d'Orsay, I came into contact with industry, which gave me the chance to collaborate with several companies: Rhône-Poulenc, Dior, Saint-Gobain, Rhodia, and Michelin. These partners have not only largely financed my research in physical chemistry but they also offered a wealth of innovative research topics. In 1996, when Professor Jacques Prost became the director of the Physico-Chimie Curie laboratory, in the Pavillon Curie built for Marie Curie, I turned to biophysics. I initiated collaborations with biologists, applying soft matter physics to the mechanics of cells and tissues. Pierre-Gilles de Gennes has been a wonderful guide throughout this scientific adventure to build my soft matter garden.

Abstract:
Recent years have seen remarkable progress in our understanding of physical aging in nondisordered systems with slow, i.e. glassy-like dynamics. In many systems a single dynamical length L(t), that grows as a power-law of time t or, in much more complicated cases, as a logarithmic function of t, governs the dynamics out of equilibrium. In the aging or dynamical scaling regime, these systems are best characterized by two-times quantities, like dynamical correlation and response functions, that transform in a specific way under a dynamical scale transformation. The resulting dynamical scaling functions and the associated non-equilibrium exponents are often found to be universal and to depend only on some global features of the system under investigation. We discuss three different types of systems with simple and complex aging properties, namely reaction diffusion systems with a power growth law, driven diffusive systems with a logarithmic growth law, and a non-equilibrium polymer network that is supposed to capture important properties of the cytoskeleton of living cells. For the reaction diffusion systems, our study focuses on systems with reversible reaction diffusion and we study two-times functions in systems with power law growth. For the driven diffusive systems, we focus on the ABC model and a related domain model and measure two- times quantities in systems undergoing logarithmic growth. For the polymer network model, we explain in some detail its relationship with the cytoskeleton, an organelle that is responsible for the shape and locomotion of cells. Our study of this system sheds new light on the non- equilibrium relaxation properties of the cytoskeleton by investigating through a power law growth of a coarse grained length in our system.

Abstract:
Nous avons étudié la friction de SBR (Styrene Butadiene Rubber) fondu sur des surfaces de faible rugosité portant des chaines ancrées de SBR, par mesures simultanées de la vitesse locale à la paroi (techniques de vélocimétrie laser par photolyse, mises au point au laboratoire pour des écoulements Couette-plan) et de la contrainte transmise. Le SBR est très enchevêtré par rapport aux études précédentes : ceci entraîne que les taux de cisaillement accessibles dans la fenêtre expérimentale peuvent être supérieurs à l'inverse du temps de reptation des chaines. Afin d'obtenir des surfaces avec des chaines de longueur et de densité contrôlées, nous avons d'abord utilisé des SBR fonctionnalisés monochlorosilane. Cette voie n'a pas abouti en raison d'impuretés résiduelles de synthèse créant des défauts dans les couches. Nous avons alors adsorbé des copolymères diblocs SBR-PDMS dont le bloc PDMS court s'adsorbe plus fortement a la surface que le bloc SBR. Dans toutes les expériences de friction sur des surfaces portant des chaines de SBR, nous avons observé le passage progressif d'un régime de glissement faible vers un régime de glissement fort en fonction du taux de cisaillement. Nous avons observé de manière quasi systématique un blocage de la contrainte sur une large gamme de vitesses de glissement, d'où une friction non linéaire, correspondant à la plage des vitesses de la transition faible -- fort glissement. La comparaison avec les modèles de Brochard-de Gennes ou d'Ajdari et al. reste qualitative compte tenu du nombre restreint de couches contrôlées, mais ces transitions de glissement et le blocage de contrainte correspondent bien an mécanisme d'étirement progressif et d'extraction des chaines ancrées en surface.

Abstract:
Le confinement nanométrique permet d'obtenir la frustration des fluctuations et/ou des transitions de phases spontanées qu'un fluide moléculaire présente en volume (i.e. en " bulk "). Le confinement au sein de matrices poreuses est donc une voie usuelle de stabilisation de phases métastables. Nous détaillons ici les propriétés structurales, dynamiques et thermodynamiques de deux systèmes moléculaires confinés : dans un premier chapitre, nous nous intéressons au cas de l'eau puis, dans un deuxième chapitre, nous traitons le cas spécifique d'un polymère semi-cristallin. Le confinement permet d'abaisser considérablement le point de fusion du fluide confiné. Cette propriété a été récemment mise à profit dans la cadre de nombreux travaux visant à tester l'existence d'un hypothétique point critique à basse température dans l'eau volumique à 228 K and 100 MPa. Dans cette contribution, nous mettons en évidence des propriétés dynamiques surprenantes de l'eau interfaciale à basse température (de 100 à 300 K). Nous proposons un modèle de percolation décrivant les transitions dynamiques et thermodynamiques que nous observons à 150, 220 et 240 K. Nous proposons une description cohérente de cette eau à deux dimensions et de ses propriétés. Nous invoquons le rôle dominant des interactions de surface pour remettre en cause la pertinence de l'utilisation de l'eau confinée pour prouver l'existence d'un point critique à basse température dans l'eau volumique. Cette étude met cependant en évidence l'existence d'une transition liquide-liquide (l'une des conditions pour observer un point critique) impliquant des molécules d'eau. Récemment, un " effet corset " a été proposé : le confinement induirait une réduction d'un ordre de grandeur du diamètre du tube de reptation d'un polymère (quelques nanomètres en volume contre quelques angströms sous confinement). Dans le second chapitre, nous utilisons une approche par diffusion de neutrons pour accéder à une description multi-échelles de la dynamique d'un polymère (en volume puis sous confinement) de l'échelle atomique à temps court (picosecondes) jusqu'à une dizaine de nanomètres, à temps long (600 nanosecondes). Cette étude détaillée de la dépendance spatiale de la relaxation temporelle des chaînes de polymère ne permet pas de mettre en évidence d'"effet corset ". De façon générale, lorsque l'on cherche à tirer profit du confinement nanométrique pour obtenir des "effets de volume", en plus d'"effets de surface" parasites décrits dans le premier chapitre, on est également confronté à une perte significative d'information induite par la moyenne spatiale des observables spectroscopiques. Nous décrivons dans le deuxième chapitre comment utiliser des matrices de confinement orientées macroscopiquement pour s'affranchir de ces effets indésirables et/ou limitants. Dans le troisième et dernier chapitre, nous définissons un système de confinement nanométrique qui permet d'associer i) une orientation macroscopique des pores et ii) une absence totale d'interactions de surface. Un tel système permet d'envisager des effets de volume unidimensionnels très significatifs et ayant une portée sur des distances macroscopiques. Nous discutons pourquoi de tels " tuyaux nanométriques" peuvent potentiellement intéresser à la fois la recherche fondamentale et l'industrie.

Abstract:
The recent development of a framework called non-affine lattice dynamics made it possible to calculate the elastic moduli of disordered systems directly from their microscopic structure and potential energy landscape at zero temperature. In this thesis different types of disordered systems were studied using this framework. By comparing the shear modulus and vibrational properties of nearest neighbour spring networks based on depleted lattices we were able to show that the dominating quantity of the system’s non-affine reorganisation during shear deformation is the affine force field. Furthermore we found that different implementation of disorder lead to the same behaviour at the isostatic point. Later we studied the effect of long range interaction in such depleted lattices with regard to spatial correlation local elasticity. We found that the implementation of long springs with decaying spring constant reproduced the spatial correlation observed in simulations of Lennard-Jones glasses. Finally we looked at simple freely rotating polymer model chains by extending the framework to angular forces and studied the dependence of the shear modulus and the vibrational density of states (VDOS) and length and bending stiffness of the chains. We found that the effect of chain length on the shear modulus and the vibrational density of states diminishes as it depends on the number of backbone bonds in the system. This number increases fast for short chains as many new backbone bonds are introduced but slows down significantly when the chain length reaches 50 monomers per chain. For the dependence on the bending stiffness we found a rich phenomenology that can be understood by looking at specific motions of the monomers relative the the chain geometry. We were able to trace back the different regimes of the VDOS to the simple model of the triatomic molecule. We also explored the limits of non-affine lattice dynamics when describing systems at temperatures T > 0 and gave an approximate solution for the shear modulus in this case.

Abstract:
Le mouillage d'un substrat soluble est une situation couramment rencontrée dans la vie de tous les jours les jours. Par exemple, les motivations pratiques de cette étude concernent la préparation de boissons à partir de poudres déshydratées, constituées de substances solubles dans l'eau telles que les glucides. Les modèles hydrodynamiques décrivant le mouillage sur un substrat non soluble ne peuvent pas expliquer les observations expérimentales dans le cas d'un liquide s'étalant sur un substrat soluble. Tay et al.(1) ont émis l'hypothèse que la fraction d'eau à la ligne de contact contrôle la valeur de l'angle de contact et ils ont montré l'importance du processus d'évaporation/condensation du solvant lors du mouillage. Dans cette étude, nous montrons que d'autres transferts de matière doivent être considérés pour améliorer la compréhension du processus de mouillage d'une couche soluble; ainsi la diffusion dans le polymère de l'eau condensée, ou directement depuis la goutte sont des processus qui contribuent à hydrater le substrat et modifier l'angle de contact de la goutte. Nous avons utilisé l'approche suivante pour réaliser cette étude: (i) pour prendre en compte la diffusion dans le substrat, nous avons réalisé des simulations en éléments finis qui permettent de valider nos arguments théoriques, (ii) des expériences d'étalement de goutte sur des couches minces de maltodextrine ont été réalisées afin d'étudier le mouillage et l'hydratation en avant de la ligne de contact. Ce travail nous permet de mettre en avant l'influence de la diffusion dans la couche qui complexifie les profils d'hydratation en avant de la ligne de contact, avec notamment l'apparition d'une région de diffusion où de l'évaporation est observée. Un diagramme de mouillage épaisseur-vitesse (e − U) avec différents régimes est établi. Nous validons ces régimes expérimentalement et plus particulièrement un régime où l'angle de contact est une fonction du produit eU. Par ailleurs, nous montrons l'influence de la transition vitreuse du polymère sur l'angle de contact et l'hydratation. Enfin, une étude préliminaire est réalisée pour comprendre l'influence de la dissolution du polymère lors du mouillage.

Full text
Abstract:
De nombreuses études théoriques et expérimentales ont été menées au cours des 30 dernières années afin d'établir le lien entre les propriétés d'interaction des protéines, leurs transitions de phase et leur auto-assemblage. Des avancées significatives ont ainsi été permises grâce à l'application de concepts et méthodes de la physique des polymères et des colloïdes. Ces études ont, pour la majeure partie d'entre elles, été limitées à des protéines d'intérêt médical et à des protéines animales. Ce travail de thèse vise à appliquer ce type d'approche aux protéines végétales afin de mieux comprendre leurs propriétés d'interaction à l'origine de leurs propriétés fonctionnelles au sein des grains et dans les matrices alimentaires. Ce travail a été mené sur un isolat de protéines de réserve du blé composé principalement de la fraction monomérique: les gliadines. Nous avons étudié les transitions de phase des gliadines afin de mieux comprendre leurs propriétés d'interaction d'une part et les structures associées d'autre part. Dans un premier temps, une procédure d'extraction a été développée afin de travailler sur un isolat de composition contrôlée dont les masses moléculaires sont comprises entre 20 kDa et 300 kDa. Le comportement de phase de cet isolat a ensuite été étudié en diminuant la qualité du solvant. Nous avons ainsi déterminé le diagramme de phases (T-Φ), où T est la température et Φv la fraction volumique des gliadines. Cette étude a mis en évidence une séparation de phase de type liquide-liquide dans le système par diminution de la température. Une analyse détaillée de la répartition des protéines au sein des deux phases en fonction de leur masse moléculaire a permis d'identifier une masse moléculaire critique séparant des protéines de comportement de type colloïdal et des protéines de comportement de type polymérique. A partir du diagramme de phase, deux études structurales ont été effectuées. La première a étudié les cinétiques de séparation de phase lors de la diminution de la température pour caractériser la dynamique locale de séparation de phase et identifier les mécanismes qui génèrent les systèmes concentrés. Deux grands types de mécanismes de séparation de phase ont été identifiés : nucléation-croissance et décomposition spinodale. La seconde étude structurale a consisté à établir l'équation d'état pression osmotique vs concentration dans des conditions de bon solvant et à caractériser la structure des dispersions de protéines associée. La relation pression osmotique vs fraction volumique a permis de mettre en évidence l'existence de plusieurs régimes de structuration, associés à des changements de structure secondaire et de propriété rhéologique. La discussion générale permet de mettre en relation les propriétés thermodynamiques déduites de cette approche expérimentale et les changements structuraux observés à différentes échelles
A substantial body of theoretical and experimental studies has been conducted over the last 30 years to establish the link between protein interaction properties, phase transitions and self-assembly. Both colloidal and polymer physics provide a new framework for understanding the driving force for proteins phase behaviour. Such studies have been limited to health-related proteins and to a few food proteins, mainly animal proteins such as casein, whey proteins. This thesis aims to apply this approach to plant proteins to better understand their interactions properties, at the basis of their functional properties within grains and food matrices. This work was carried out on a wheat storage protein isolate mainly composed of the monomeric fraction: gliadins.The objective of this PhD thesis is to investigate the phase transitions of wheat proteins to develop our knowledge on their interaction properties and the associated structures. We organized our experimental approach in five steps. First, we developed an extraction procedure to work on a protein isolate of controlled composition with molecular weight ranging from 20 to 300 kg mol-1. Then, we investigated the phase behaviour of the protein isolate by decreasing the solvent quality, here the temperature. We determined the T-Φ phase diagram, where T is the temperature and Φv the protein volume fraction, that maps the phase and structural transitions of the proteins. This study showed the existence of a liquid-liquid phase separation in the system upon a temperature decrease. We evidenced two different behaviours among proteins as a function of their MWs and highlighted a critical protein size above which the molecular weight is the key determinant of the protein properties. From the phase diagram, two structural studies were conducted. The first one studied the kinetics of phase separation upon temperature decrease to characterize the local dynamics of phase separation and to identify the mechanisms that generate concentrated systems. Two main mechanisms of phase separation have been identified: nucleation-growth and spinodal decomposition. The second one studied the effect of protein concentration on the multi-scale structure of wheat gliadins in good solvent. The integration of all these results allowed us to build the phase diagram of wheat gliadins, integrating thermodynamic and structural data

Abstract:
Polymer science is rapidly advancing towards the precise construction of synthetic macromolecules of formidable complexity. The impressive advances in control over polymer composition, topology and uniformity, enabled by the living polymerisation revolution, now permit the introduction of compartmentalisation within macromolecules. Despite the straightforward and versatile synthetic approaches to produce block copolymer, nanostructures built-up from these linear building-blocks rarely reaches dimensions beyond the 5–50 nm range and can be sensitive to their environment. The development of robust controlled polymerisation techniques has enabled the synthesis of covalently-bond polymer architectures that can be used as nano-scale building-blocks. One of these architectures are molecular polymer brushes (also known as bottlebrush polymers or cylindrical polymer brushes). Molecular polymer brushes (MPBs) are unique materials that possess astonishing properties arising from their densely grafted and extended chain structure. The field of MPBs, especially as compartmentalised entities, is rapidly growing. Recent efforts have focussed on achieving MPBs with programmed complexity and the introduction of orthogonal chemical functionality. Compartmentalised brushes can elevate their functionality beyond that of their linear constituent parts, thus offering immense potential in self-assembly and template chemistry. The aim of this thesis is to demonstrate how the compartmentalisation in MPBs can be used for the construction of complex, yet precise, polymer nano- and microstructures with the scope to develop advanced functional materials.

Full text
Abstract:
Les défauts créés dans les polymères soumis aux rayonnements ionisants, en atmosphère inerte, suivent pratiquement tous la même évolution en fonction de la dose. Lorsque la dose augmente, leur concentration augmente puis se stabilise. L'hypothèse retenue pour expliquer ce comportement est la mise en place de transferts d'énergie vers les défauts macromoléculaires créés aux faibles doses. Ceux-ci agissent comme des pièges à énergie et conduisent donc à la radio-stabilisation du polymère. Au cours de cette thèse, nous nous sommes attachés à la quantification de l'apport de l'insaturation trans-vinylène dans le comportement sous rayonnements ionisants du polyéthylène. Avec le dihydrogène, ce groupement compte parmi les défauts majoritaires créés dans ce polymère. Du fait de la variété des défauts et de la simultanéité de leur création, nous avons choisi une méthodologie nouvelle consistant à insérer par voie de synthèse, de manière spécifique et à différentes concentrations, des insaturations de type trans-vinylène, dans les chaînes de polyéthylène. Les polymères résultants ont été irradiés, en atmosphère inerte, avec des rayonnements de faibles TEL (gamma, bêta) et de forts TEL (ions lourds). Tant les défauts macromoléculaires que l'émission de dihydrogène ont été quantifiés. Il apparaît, sur la base des résultats expérimentaux, que l'apport des groupements trans-vinylènes est prédominant dans la radio-stabilisation du polyéthylène en atmosphère inerte.

Abstract:
Tom McLeash (2005), Professor of Natural Philosophy, says that “in science nothing stays the same. This is true not only at the level of discoveries, experiments, and theories, but also for the coherent structures and disciplines of the scientific community itself. A fascinating recent example has been the emergence of the field of ‘soft matter’ from a recognition that problems in polymer science, colloid science, liquid crystals, surfactant systems, foams, and even biological materials must draw on the same experimental and theoretical tools to make progress.” In this paper, we aim to highlight the concept of soft (condensed) matter physics and its association with industrial food science and (bio)technology within the scope of a new term “food physics”.

Abstract:
Abstract Two-terminal adaptive materials and circuit elements that mimic the signal processing, learning, and computing capabilities of biological synapses are essential for next-generation computing systems. To this end, we have recently developed resistive (ion channel) and capacitive (lipid bilayer) memory elements that mimic the composition, structure, and plasticity of biological synapses. Unlike solid-state counterparts, these biomolecular systems are low-power, analog, less noisy, biocompatible, and capable of exhibiting multiple timescales of short-term synaptic plasticity. However, lipid membranes lack structural stability and modularity necessary for a long-lasting adaptive material system. To address this issue, we propose the replacement of phospholipids with amphiphilic polymers to create artificial membranes, which have been demonstrated to be more durable than phospholipids. With the focus on memory capacitors, we demonstrate that polymeric bilayers can exhibit pinched hysteresis in the Q-v plane because of voltage-induced geometrical changes. Further, we demonstrate that the memcapacitive response is altered based on the surrounding oil medium; smaller oil molecules are retained at higher volume in the membrane, so that thicker bilayers have lower nominal capacitance but can vary this value by over 400%. Finally, we present a physics-based model that enables us to predict the device’s areal voltage-dependent response. Polymeric bilayers represent a significant enhancement in the field of soft-matter, geometrically-reconfigurable memcapacitors, and their highly customizable compositions will allow for a finely tuned electrical response that has a future in brain-inspired materials and circuits.
