Abstract:
With potassium acetate as an intercalation agent, kaolinite-potassium acetate(KAc) intercalation complexes was prepared. Afterwards, nano-kaolinite was successfully made through exfoliated intercalation complexes using power ultrasonic. The intermediate and final products were characterized by X-ray diffraction(XRD), infrared spectroscopy(IR), laser particle size analyzer, and scanning electron microscope (SEM). The results show that intercalation of KAc into kaolinite resulted in a crystal space expansion, from a basal spacing of 7.14Ǻ to 14.20 Ǻ, and the intercalation rate was about 80%. KAc intercalation causes the weakening of interlayer stability. It was shown that the particles of nano-kaolinite is very thin lamellar in shape, whose average thickness, average particle size, are 50 nm and 450 nm respectively.

Abstract:
Kaolinite/benzamide complex was prepared by displacement reaction of a kaolinite/dimethylsulphoxide (DMSO) intercalation complex with melted benzamide. The whole process was recorded by powder X-ray diffractometry (PXRD) and Fourier-transformed infrared spectroscopy (FTIR). Those PXRD and FT-IR indicated that there are two stages in the process of melted benzamide replacing intercalation. The first stage is the deintercalation of DMSO molecules in the kaolinite/dimethylsulphoxide intercalation complex. And the second stage is the melted benzamide intercalation.

Abstract:
The mechanism of intercalation and the ability of double stranded DNA (dsDNA) to accommodate a variety of ligands in this manner has been well studied. Proposed mechanistic steps along this pathway for the classical intercalator ethidium have been discussed in the literature. Some previous studies indicate that the creation of an intercalation site may occur spontaneously, with the energy for this interaction arising either from solvent collisions or soliton propagation along the helical axis. A subsequent 1D diffusional search by the ligand along the helical axis of the DNA will allow the ligand entry to this intercalation site from its external, electrostatically stabilized position. Other mechanistic studies show that ethidium cation participates in the creation of the site, as a ligand interacting closely with the external surface of the DNA can cause unfavorable steric interactions depending on the ligands' orientation, which are relaxed during the creation of an intercalation site. Briefly, such a site is created by the lengthening of the DNA molecule via bond rotation between the sugars and phosphates along the DNA backbone, causing an unwinding of the dsDNA itself and separation between the adjacent base pairs local to the position of the ligand, which becomes the intercalation site. Previous experimental measurements of this interaction measure the enthalpic cost of this part of the mechanism to be about −8 kcal/mol. This paper reports the observation, during a computational study, of the spontaneous opening of an intercalation site in response to the presence of a single ethidium cation molecule in an externally bound configuration. The concerted motions between this ligand and the host, a dsDNA decamer, are clear. The dsDNA decamer AGGATGCCTG was studied; the central site was the intercalation site.

Abstract:
Abstract Unexpected intercalation-dominated process is observed during K+ insertion in WS2 in a voltage range of 0.01–3.0 V. This is different from the previously reported two-dimensional (2D) transition metal dichalcogenides that undergo a conversion reaction in a low voltage range when used as anodes in potassium-ion batteries. Charge/discharge processes in the K and Na cells are studied in parallel to demonstrate the different ion storage mechanisms. The Na+ storage proceeds through intercalation and conversion reactions while the K+ storage is governed by an intercalation reaction. Owing to the reversible K+ intercalation in the van der Waals gaps, the WS2 anode exhibits a low decay rate of 0.07% per cycle, delivering a capacity of 103 mAh·g-1 after 100 cycles at 100 mA·g-1. It maintains 57% capacity at 800 mA·g-1 and shows stable cyclability up to 400 cycles at 500 mA·g-1. Kinetics study proves the facilitation of K+ transport is derived from the intercalation-dominated mechanism. Furthermore, the mechanism is verified by the density functional theory (DFT) calculations, showing that the progressive expansion of the interlayer space can account for the observed results.

Abstract:
The formation and dissolution of aluminum carbide is considered the primary factor affecting the life of aluminum electrolysis cells. Herein, the characteristics of sodium-graphite intercalation compounds (Na-GICs)were measured and the formation mechanism of Al4C3duringthe aluminum electrolysis process was experimentally studied. The Na-GIC characteristics and the products of aluminum and Na-GIC reactions were investigated by Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy. The results showed that graphite can react with the sodium metal to form Na-GICs, which were detectable by Raman spectroscopy. Sodium that inserted into the graphite layered structure acted as an intercalation agent to change the original graphite layered structure and increase the volume and specific surface area of graphite. Further, Al4C3wasproduced by using sodium-graphite intercalation compounds and aluminum as materials. Thus, the presence of sodium plays an important role in the formation process of Al4C3in aluminum electrolysis cells.

Full text
Abstract:
The presence of clays in the sands used for concrete production interferes with the development of the fluidity of concrete, producing an instantaneous slump loss just after batching and the premature loss of fluidity. This interference occurs with all types of additives and clays but is especially problematic when combining sands containing expansive clays such as montmorillonites with new-generation high water-reducer/superplasticizer admixtures based on polycarboxylate polymers (PCE). Water-reducers based on PCE polymers offer much better performance than traditional superplasticizers based on sulfonated naphthalene polymers (BNS) and sulfonated melamine polymers (MNS), making great advances in concrete technology, both from the technical and economical point of view as in reducing the environmental impact associated to concrete. However, these advantages are inhibited when sands contain clays of the expansive type in their composition. All the preventive or corrective measures to mitigate the harmful effect of clays contained in sands result in increases of production costs and in greater environmental impact. For this reason, during the last years it has been tried to develop polymeric structures that offer the same benefits than polymers PCE but with improved tolerance against clays of the expansive type, such as montmorillonite clays, but without getting to reach solutions with guarantees of success, due to the complexity of the interaction process between PCE polymers and montmorillonite clays. This doctoral thesis aims to deepen knowledge about the mechanism of interaction between PCE polymers and montmorillonite clays, assuming that the deep understanding of the interaction mechanism is the essential previous step to finally develop high-performance, clay-insensitive superplasticizers for concrete. For this, the research is structured in three parts, motivated by the discrepancies that the current model of interaction proposed shows with the experimental results of sorption and fluidity loss. In the first part, it is intended to develop a test method that allows to observe the real expansion profiles of the clays in such a way that the mentioned discrepancies can be clarified. Secondly, with the proposed test method, it is intended to identify how the structure of PCE polymers, as well as the dosage used, influences on the expansion of montmorillonite clays produced by the absorption of polymer. And, thirdly, to identify how the properties of clay affect the interaction process. The first phase of the research campaign has made it possible to propose an improved test method for the d-spacing determination that revealed the real intercalation behavior, by which the number of PCE side chains intercalated into the interlaminar space of montmorillonite clays is up to ten times higher than that deducted from the traditional analytical method. And from the new test method proposed it has been possible to clarify the role of the different structures of PCE polymers and the properties of montmorillonite clays in the intercalation mechanism, in agreement with the experimental results of fluidity loss and of sorption behavior. Based on the mentioned achievements, an extended model for the intercalation mechanism has been proposed, whereby montmorillonite clays inhibit the dispersing capacity of PCE polymers, being able to identify the parts and properties of both the clay and the PCE polymers that control this process. With this contribution, the knowledge of the intercalation mechanism is extended to understand how the interaction between PCE polymers and montmorillonite clays is developed, which is the main objective of this research.<br>La presencia de arcillas en las arenas empleadas para producir hormigón interfiere en el desarrollo de la fluidez de los hormigones, produciendo una pérdida de cono instantánea tras el amasado y la pérdida prematura de fluidez. Esta interferencia se produce con todos los tipos de aditivos y de arcillas, pero es especialmente problemática cuando se combinan arenas que contienen arcillas expansivas del tipo montmorillonita con aditivos superplastificantes de nueva generación basados en polímeros de policarboxilato (PCE). Este tipo de aditivos superplastificantes basados en polímeros de PCE ofrecen prestaciones muy superiores a las de los superplastificantes tradicionales basados en polímeros de naftalensulfonatos (BNS) y melaminas sulfonadas (MNS), aportando grandes mejoras en la tecnología del hormigón, tanto desde el punto de vista técnico y económico como en la reducción del impacto ambiental asociado al hormigón. Sin embargo, estas ventajas quedan inhibidas cuando las arenas contienen arcillas del tipo expansivo en su composición. Todas las medidas preventivas o correctivas aplicadas para mitigar el efecto dañino de las arcillas contenidas en las arenas acarrean incrementos de coste de producción y mayor impacto ambiental. Por este motivo, durante los últimos años se ha intentado desarrollar estructuras poliméricas que ofrezcan las mismas prestaciones que los polímeros de PCE pero con mayor tolerancia frente a arcillas del tipo expansivo, como por ejemplo las montmorillonitas, pero sin llegar a alcanzar soluciones con garantías de éxito, debido a la complejidad del proceso de interacción entre los polímeros de PCE y las arcillas montmorillonitas. Esta tesis doctoral pretende profundizar en el conocimiento en torno al mecanismo de interacción entre los polímeros de PCE y las arcillas montmorillonita, entendiéndose que la comprensión del mecanismo de interacción es la etapa previa esencial para lograr, finalmente, desarrollar aditivos superplastificantes de altas prestaciones e insensibles a las arcillas. Para ello, la investigación se estructura en tres partes, motivado por las discrepancias que el actual modelo de interacción propuesto muestra con los resultados experimentales de sorción y de pérdida de fluidez. En primer lugar, se pretende desarrollar un método de ensayo que permita observar el perfil de expansión de la arcilla real de tal modo que las discrepancias mencionadas puedan ser clarificadas. En segundo lugar, con el método de ensayos propuesto, se pretende identificar como influye la estructura del polímero de PCE, así como su dosificación, en la expansión de la arcilla producida por la absorción de polímero. Y, en tercer lugar, identificar como influyen las propiedades de la arcilla en el proceso de interacción. La primera fase de investigación ha permitido proponer un método de ensayo para el factor de expansión d-spacing que vislumbra que el número de cadenas laterales del polímero de PCE intercaladas dentro del espacio interlaminar de las montmorillonitas es hasta más de diez veces superior al deducido con el método analítico tradicional. Y a partir del nuevo método de ensayo ha sido posible clarificar el rol de las diferentes estructuras de los polímeros de PCE y de las propiedades de la arcilla en el mecanismo de intercalación, en consonancia con los resultados de fluidez y de sorción. A partir de los logros mencionados, se ha propuesto un modelo extendido del mecanismo de intercalación por el cual las arcillas montmorillonitas inhiben el efecto dispersante de los polímeros de PCE, pudiendo identificar cuáles son las partes y propiedades tanto de la arcilla como de los polímeros de PCE que controlan este proceso. Con esta aportación, se amplía el conocimiento para comprender como se desarrolla la interacción entre los polímeros de PCE y las arcillas montmorillonitas, que es el objetivo principal de esta investigación.

Abstract:
Le travail de thèse, présenté dans ce mémoire, est consacré à l'étude de nouveaux matériaux d'électrode pour batterie lithium-ion pour le stockage d'énergie photovoltaïque. Ce type de production d'énergie impose de nombreuses intermittences de charge, des non synchronisations entre les périodes de production et de consommation, etc. L'objectif est d'évaluer le comportement de différents types de matériau d'électrode dans des batteries soumises à des profils de charge photovoltaïque pour ensuite sélectionner les plus adaptés à ce stockage spécifique d'énergie. Les matériaux choisis, Li4Ti5O12, Li2Ti3O7, NiP3, TiSnSb, présentent tous des mécanismes de réaction vis-à-vis du lithium très différents. Afin d'améliorer la durée de vie de ces matériaux d'électrodes, un travail d'optimisation des performances électrochimiques a été effectué en travaillant sur leur synthèse puis sur la formulation des électrodes. La formulation d'électrode en utilisant la carboxymethylcellulose sodique a notamment donné d'excellents résultats. La caractérisation de leurs propriétés physico-chimiques a été réalisée par diffraction des rayons X, in situ et en température, MEB, ATD, cyclage galvanostatique, etc.). Afin de reproduire des profils représentatifs de la production photovoltaïque à l'échelle des accumulateurs expérimentaux de laboratoire, un banc de simulation a été élaboré et validé avec un accumulateur de référence à base de Li4Ti5O12. Après cette étape de validation, les différents matériaux d'électrode ont été testés en condition photovoltaïque. Cette étude a permis de montrer que les intermittences de courte de durée (passages nuageux) et les régimes variables qu'impose ce type de production n'ont pas que peu d'influence sur les propriétés électrochimiques de l'ensemble de ces matériaux. Cependant, les périodes d'absence de production (nuit, journée pluvieuse, etc.) correspondant à une relaxation pour le matériau peuvent avoir un impact important. Les matériaux de conversion (NiP3, TiSnSb) ont montré de surprenants bons résultats. Enfin, les observations montrent que chaque type de matériau (mécanisme électrochimique différent) pourrait convenir i) à un type de production photovoltaïque, c'est à dire à une zone géographique et ii) à un type d'application particulière<br>The thesis work, presented in this manuscript, is devoted to the study of new materials for lithium-ion battery for storing solar energy. This type of energy production imposes intermittent loading, non-synchronization between periods of production and consumption, etc. The objective is to evaluate the behavior of different types of electrode material in batteries under photovoltaic (PV) charge profiles and then to select the most suitable for this specific energy storage. The chosen materials, Li4Ti5O12, Li2Ti3O7, NiP3, TiSnSb, follow all very different reaction mechanisms versus lithium. To improve the cycling life of these electrode materials, a work on electrochemical performance optimization was performed by working on the synthesis and the electrode formulation. The electrode formulation, using in particular carboxymethyl cellulose, presented excellent results. Characterization of their physico-chemical properties was carried out by X-ray diffraction, in situ and as function of temperature, SEM, DTA, galvanostatic cycling, etc.). To reproduce representative profiles of the photovoltaic production at the experimental batteries scale, a test bench has been developed and validated with reference batteries (Li4Ti5O12). After this step of validation, different electrode materials were tested under photovoltaic conditions. This study shows that both intermittences with short duration (clouds) and variable rates of current imposed by this type of production don't strong influence on the electrochemical properties of all these materials. However, periods of no production (night, rainy day, etc.), corresponding to a relaxation for the material, can impact significantly. Materials following conversion mechanism (NiP3, TiSnSb) showed surprising good results. Finally, the observations indicated that each type of material (with different electrochemical mechanism) could be adapted to i) a type of photovoltaic production, ie to a geographical area and ii) a type of application

Abstract:
Ce travail présente les études électrochimiques et structurales menées sur deux systèmes : P2/O3-NaxMn1-yFeyO2 et O’3-NaxNiO2 utilisés en tant que matériaux d’électrode positive pour batteries Na-ion.Concernant le système P2/O3-NaxMn1-yFeyO2, l’étude par diffraction des rayons X menée in situ pendantla charge de batteries a montré de nombreuses transitions structurales. Que leur structure soit de type P2ou O3, les matériaux présentent une phase distordue pour les taux d’intercalation (x) les plus élevés etune phase très peu ordonnée pour les taux d’intercalation les moins élevés. Entre ces deux étatsd’intercalation, les phases de type P2 présentent moins de transitions que les phases de type O3. Celaentraine de meilleures propriétés électrochimiques pour les phases de type P2 (meilleure capacité endécharge, meilleure rétention de capacité…).

Ces transitions s’accompagnent de mises en ordre Na+ - lacunes dans le matériau. La tailledes grains a montré avoir un intérêt majeur puisqu’elle influe sur le nombre de phases présentessimultanément dans le matériau.

Concerning theP2/O3-NaxMn1-yFeyO2 systems, in situ X-ray diffraction carried out during the charge of the batteriesshowed that both materials undergo several structural transitions. Both the P2 and O3 phases show adistorted phase for the higher intercalation rates (x) and a poorly ordered phase for the lower ones.Between these two states, P2-based materials exhibit less structural transitions than the O3-based ones.This is correlated to the better electrochemical properties the P2-based materials exhibit (better dischargecapacity, better capacity retention…). X-ray absorption and 57Fe Mössbauer spectroscopies showed thatthe Mn4+/Mn3+ and Fe4+/Fe3+ redox couples are active upon cycling, respectively at low and high voltage.Concerning O’3-NaNiO2, in situ X-ray diffraction carried out during the charge of O’3-NaNiO2//Nabatteries showed several structural transition between O’3 and P’3 structures, resulting from slab glidings.These transitions are accompanied by Na+ - vacancies ordering within the “NaO6” slabs. Upon discharge,the material does not come back to its initial state and, instead, the Na≈0.8NiO2 phase represents themaximum intercalated state. The occurrence of this limiting phase prevents O’3-NaNiO2 to be consideredas an interesting material for real Na-ion applications

Abstract:
Notre travail s'inscrit dans le cadre de l'etude par resonance magnetique nucleaire (rmn) d'une des lesions majeures de l'adn : le site abasique. Celui-ci resulte de la perte d'une base nucleique conduisant a la formation du 2-desoxyribose ou de sa forme oxyde, la 2-desoxyribonolactone. La 2-desoxyribonolactone fait l'objet de nombreux travaux mais reste une lesion mal connue, tant d'un point de vue chimique, biologique que structural. Nous avons determine par rmn et modelisation moleculaire, la premiere structure d'un oligonucleotide contenant cette lesion. Par comparaison avec la structure du duplex de reference non modifie et caracterise de la meme facon, nous avons mis en evidence les deformations specifiques induites par la 2-desoxyribonolactone. Une deuxieme partie est consacree a la determination par rmn du mode d'interaction de composes qui reconnaissent specifiquement le site 2-desoxyribose. L'interet majeur de ces molecules est qu'elles pourraient inhiber le systeme de reparation de l'adn dans la cellule. L'etude a ete realisee sur un oligonucleotide contenant un residu tetrahydrofurane, analogue stable du 2-desoxyribose. Nous avons montre qu'une molecule de type base-chaine-intercalant qui potentialise in vitro et in vivo l'effet cytotoxique d'un agent alkylant anticancereux (le bcnu), se complexe de facon specifique avec l'adn. La base de la drogue s'insere notamment dans la loge abasique et forme des liaisons hydrogene de type watson-crick avec la thymine qui fait face a lesion. Par ailleurs, l'etude de l'interaction entre un macrocycle de type bisacridine et ce meme oligonucleotide a montre que la molecule traverse l'adn, une acridine s'intercalant dans la loge abasique, l'autre a une paire de base cote 3, et les chaines polyaminees se positionnent chacune dans un sillon. Une telle molecule constitue ainsi un bon module de reconnaissance du site 2-desoxyribose et pourrait servir de modele a la conception de molecules inhibitrices du systeme de reparation. Ce travail apporte des informations nouvelles sur les lesions abasiques de l'adn et devrait, contribuer a une meilleure comprehension des phenomenes biologiques s'y rapportant ainsi qu'au developpement d'autres molecules a activite anticancereuses.

Abstract:
The intrinsic electrochemical behavior of Graphite Intercalated Compounds (GICs) during formation offers the potential for high-force, high-strain solid-state actuation applications. To explore this behavior we submitted a “model” system, highly-oriented pyrolytic graphite (HOPG)/sulfuric acid (H2SO4), to axial compressive loads from 0 to 8 MPa, and measured the intercalation response in terms of voltage and displacement. We observed strains greater than 30% between 2 and 6 MPa, confirming the potential of GIC formation as a viable actuating mechanism. Further studies are planned in order to perform more precise analysis and examine alternate GICs.

Abstract:
The actuation mechanisms of cnt-based materials are still controversially discussed. It is not common sense whether it is a macroscopic volume effect caused by ion intercalation or electrostatic repulsion of equally charged cnts or a nanoscopic effect of filled electron anti-bonding orbitals of the carbon atom or interactions with ions docking on the carbon surface. In the presented paper arrays of highly aligned multi-walled carbon nanotubes (mwcnts) are used which are stabilized by a polypyrrole-coating. The samples are tested along the cnt-orientation and in perpendicular mode to analyze the influence of the structure-ion interaction. The mwcnt-arrays exhibit only a total length of approximately 2.8 mm but by coating with polypyrrole larger geometries can be tested. The actuation is analyzed using an in-plane test and an actuated tensile testing. Free strain can be detected using the first set-up, the second method is carried out to evaluate the mechanical stability of the samples. As might be expected, the material shows a strong anisotropic active behavior with the actuation along the tube axis being only half of the value detected at the perpendicular oriented samples. The findings point out that an intercalation of ions into the charged CNT-architecture seems here to be the dominating mechanism.
