Abstract:
AbstractThe phenomenon of ion migration in solids forms the basis for a wide variety of electrochemical applications, ranging from power generators and chemical sensors to ionic switches. Solid-state ionics (SSI) is the field of research concerning ionic motions in solids and the materials properties associated with them. Owing to the ever-growing technological importance of electrochemical devices, together with the discoveries of various solids displaying superior ionic conductivity at relatively low temperatures, research activities in this field have grown rapidly since the 1960s, culminating in “nanoionics”: the area of SSI concerned with nanometer-scale systems. This theme issue introduces key research issues that we believe are, and will remain, the main research topics in nanoionics and SSI during the 21st century. These include the application of cutting-edge experimental techniques, such as secondary ion mass spectroscopy and nuclear magnetic resonance, to investigate ionic diffusion in both bulk solids and at interfaces, as well as the use of atomic-scale modeling as a virtual probe of ionic conduction mechanisms and defect interactions. We highlight the effects of protonic conduction at the nanometer scale and how better control of interfaces can be employed to make secondary lithium batteries based on nanoionics principles. Finally, in addition to power generation and storage, the emergence of atomic switches based on cation diffusion shows great promise in developing next-generation transistors using SSI.

Abstract:
A controlled experimental study of the sorption of colloidal humic substances (humic acid) and a non-ionic hydrophobic organic compound (naphthalene) onto typical inorganic constituents of aquifer solids was performed using four types of model solid phases {i.e., individual model solids (montmorillonite, kaolinite, amorphous aluminosilicate gel, and amorphous iron oxides) and combined model solids (montmorillonite coated by amorphous aluminosilicate gel or iron oxides)}, which are synthesized in the laboratory. The batch experimental results indicated that the sorption of non-ionic hydrophobic organic compounds and colloidal humic substances onto the aquifer solids is significantly influenced by the solid composition. And it was also suggested that the non-ionic hydrophobic organic compounds which have greater hydrophobicity are considered to be sorbed and stabilized by the mobile colloidal humic substances in groundwater, and these colloids may act as a third phase that can increase the amount of compounds that the flow of groundwater can transport. On the other hand, the non-ionic hydrophobic organic contaminants of smaller hydrophobicity may be retarded significantly with the sorption of colloidal humic substances onto the aquifer solids.

Abstract:
A series of ionic solid nanomaterials denoted as IS1, IS2 and IS3 have been prepared using butylmethylimidazolium bromide ([BMIM][Br]) ionic liquid as cation, and three types of heteropolyacid; phosphotungstic acid (H3PW12O40), phosphomolybdic acid (H3PMo12O40), and silicotungstic acid (H4SiW12O40) as anion. The nanomaterials were characterized by FTIR, XRD, SEM, TGA, NH3-TPD and BET. Its catalytic performance was investigated by catalyzing glucose conversion to levulinic acid and hydroxymethylfurfural. It was observed that the ionic solids have higher acidity with semi amorphous structure, higher thermal stability and insignificant water content compared to the parent compound. Among the three prepared ionic solids, phosphomolybdic based ionic solid (IS2) exhibited the best catalytic performance due to its highest total acidity.

Abstract:
A fluorescence quenching method was used to determine the sorption of polycyclic aromatic hydrocarbons (PAHs) onto natural solids in batch experiments. This method is based upon the observation that PAHs fluoresce in aqueous solution but not when associated with natural solids. It avoids problems of incomplete solid-liquid separation. As natural solids, eleven different USEPA soils and sediments were used. Anthracene and 2-aminoanthracene, which are respectively non-ionic and ionic PAHs, were chosen as sorbates. The fractional decrease in fluorescence intensity as a function of added natural solid concentration is referred to as Stem-Volmer plots. The plots were linear for all natural solids investigated. The conditional sorption coefficients (Ksc) at pH 6 through 8 and I=0.1 M were obtained as the slopes of the plots. While the Ksc values of anthracene were independent of pH, the values of 2-aminoanthracene decreased with increasing pH. The Ksc values of anthracene correlated well with the organic carbon content of natural solids. However, the values of 2-aminoanthracene did not depend on the content of organic carbon in natural solids. For 2-aminoanthracene, inorganic matrices of the natural solids may contribute to the sorption.

Abstract:
The study of crystalline materials has played a prominent role in solid state physics, whose basic theories were formulated for crystalline matter. However, disordered materials are more abundant in nature than crystalline ones, and, moreover, many practical applications use materials which are weakly or strongly disordered, such as molecular crystals, glasses, plastic crystals, liquids, polymers, or liquid crystals. In glasses, for example, the arrangement of the constituent atoms or molecules lacks any long-range order. From a fundamental viewpoint, we still lack an understanding of the properties of disordered materials and of the glass transition: understanding the many fascinating issues related with disorder requires in fact the use of concepts that are far from the well-known solid-state concepts associated with periodicity. From an applied perspective, the intense research in disordered solids is driven by the technological importance of these materials in daily life. From an electrical viewpoint, disordered solids can conduct electricity by transport of either electrons or ions. In the first case, disordered materials display lower electrical conductivity than their crystalline counterparts, due to localization of conduction electrons due to disorder, so that electron hopping is the main charge transport mechanism. On the other hand, the same disorder may allow the diffusion of ions through interstitial sites; the ionic conductivity of disordered materials is normally higher than the crystalline counterparts. This thesis presents an experimental study of the conduction properties and molecular dynamics of molecular solids made of fullerene derivatives (C60Br6, C60(ONa)24) and of dinitrile molecules such as succinonitrile (C2H4(CN)2) and glutaronitrile (C3H6(CN)2). The studied materials display, depending on the case, mainly electronic, protonic, or ionic conduction. The thesis provides insight into the different possible types of charge conduction in organic molecular materials and on related physical processes such as space-charge relaxations. In C60Br6 we observe n-type electronic conduction below room temperature and a non-trivial phase behavior. The temperature dependence of the dc conductivity of this organic semiconductor is in agreement with the variable-range hopping model. C60(ONa)24 has even richer phase behavior. It is synthesized as a polycrystalline hydrate, and can be obtained as pure material by heating to high temperature. We show that while the pure material is an n-type (electron) semiconductor, exposing it to humid atmosphere leads to a dramatic conductivity enhancement due to charge transport through the hydration layers, which is likely mediated by a proton exchange mechanism as in bulk water and ice. We also show that the dc conductivity of the hydrate is strongly temperature dependent across the dehydration process, and that both pure and hydrated forms display a conductivity-related dynamic process associated with accumulation of electrons at grain boundaries. The presence of water has strong impact on such frequency-dependent charge-accumulation dynamics. We finally analyze the relaxation dynamics and the ionic conductivity of plastic-crystalline ionic conductors, in particular the plastic cocrystals of succinonitrile with glutaronitrile. In plastic crystals, the molecules occupy lattice sites but undergo free rotational motions about their centers of mass. We find that succinonitrile-glutaronitrile cocrystals are the first ever known plastic crystals to display a perfect correlation between the ion drift and the on-site reorientational dynamics. Doping the cocrystals with Li salts boosts the conductivity but breaks down this perfect correlation. This indicates that the rotation-drift correlation is only valid when charge transport is dominated by self-diffusion of molecular (dinitrile) ions, and that it is a consequence of the correlation between rotational and diffusional time scales.<br>El estudio de los materiales cristalinos juega un papel destacado en la física del estado sólido. Sin embargo, los materiales desordenados son más abundantes en la naturaleza que los cristalinos y, además, muchas de las aplicaciones prácticas utilizan materiales que son débilmente o fuertemente desordenados, como vidrios, líquidos, cristales plásticos, cristales moleculares, polímeros, o cristales líquidos. Desde un punto de vista fundamental, aún carecemos de una comprensión de de los materiales desordenados y de la transición vítrea: la comprensión de las propiedades asociadas desorden requiere el uso de conceptos que se alejan de los aplicables al estado cristalino. Desde una perspectiva aplicada, la investigación en los sólidos desordenados está promovida por la importancia tecnológica de estos materiales en la vida cotidiana. Los sólidos desordenados pueden conducir electricidad por transporte de electrones o de iones. En el primer caso, los materiales desordenados muestran menor conductividad que sus respectivas fases cristalinas, debido a la localización de los electrones de conducción por la existencia de desorden, que da lugar a saltos de electrones como principal mecanismo de transporte de carga. Por otro lado, el mismo desorden puede permitir la difusión de iones a través de intersticios; la conductividad iónica de materiales desordenados es más alta que sus fases homólogas cristalinas. Esta tesis presenta un estudio experimental de la conducción eléctrica y de la dinámica molecular de sólidos moleculares formados por derivados de fullereno (C60Br6, C60(ONa)24) o por moléculas con dos grupos nitrilos (succinonitrila (C2H4(CN)2), glutaronitrila (C3H6 (CN)2)). Estos materiales presentan, según el caso, conducción electrónica, protónica, o iónica. La tesis analiza los diferentes tipos de conducción de carga en materiales moleculares así como los procesos físicos relacionados, tales como las relajaciones de carga espacial. En el material C60Br6 observamos conducción electrónica tipo n y un comportamiento de fase no trivial. La dependencia de la conductividad con la temperatura está de acuerdo con el modelo de salto de rango variable (VRH). El C60(ONa)24 tiene un comportamiento de fase aún más rico. Se sintetiza como un hidrato policristalino, y se puede obtener como material puro por calentamiento. Mientras que el material puro es un semiconductor de tipo n, su exposición a una atmósfera húmeda aumenta la conductividad de forma dramática debido al transporte de carga a través de las capas de hidratación, lo que probablemente se debe a un mecanismo de intercambio de protones como en el agua pura o en el hielo. La conductividad del hidrato depende fuertemente de la temperatura en el proceso de deshidratación. Ambas formas, pura e hidratada, muestran un proceso dinámico asociado a la acumulación de electrones en los límites de grano. La presencia de agua tiene un fuerte impacto en tal proceso. Por último se analizan la dinámica molecular y la conductividad iónica de cristales plásticos, en particular, de las aleaciones moleculares en fase plástica formadas entre la succinonitrila y la glutaronitrila. En las fases plásticas las moléculas ocupan los sitios cristalográficos de la red, pero se encuentran orientacionalmente desordenadas. Se demuestra que las aleaciones succinonitrila-glutaronitrila son los primeros cristales plásticos que se conocen en los que existe una correlación perfecta entre la corriente de iones y la dinámica reorientational de las moléculas en los sitios cristalográficos. El dopaje de las aleaciones con sales de Li aumenta la conductividad pero destruye la correlación anterior, lo que indica que la correlación sólo es válida cuando el transporte de carga está dominado por la difusión de iones moleculares. Tal correlación puede ser consecuencia de una correlación entre las escalas de tiempo de rotación y de difusión.

Abstract:
In the past decade, the field of NMR spectroscopy has seen the emergence of ever more powerful superconducting magnets, which has opened the door for the observation of many traditionally challenging or non-receptive nuclei. In this dissertation, a variety of ionic solids with organic coordination environments are investigated using quadrupolar solid-state NMR experiments with an ultrahigh-field magnet (21.1 T). Two general research directions are presented including a 79/81Br solid-state NMR study of a series of 6 triphenylphosphonium bromides for which single-crystal X-ray structures are reported herein. A second research direction is also presented wherein alkaline-earth metal (25Mg, 43Ca, and 87Sr) solid-state NMR is used to characterize a systematic series of 16 aryl and alkyl carboxylates. In both studies, the quadrupolar nuclei studied are deemed “exotic” due to their unreceptive nature to NMR spectroscopic analysis including low natural abundances, large quadrupole moments, or low resonance frequencies. A variety of coordination modes to alkaline-earth metals, including N-atom coordination, are characterized herein for the first time using alkaline-earth metal solid-state NMR. In all cases, the electric field gradient (EFG) and chemical shift (CS) tensors are characterized and correlated to structural features such as interatomic distances measured from the crystal structure of the compound under study. In all of the projects undertaken herein, the gauge-including projector-augmented-wave density functional theory (GIPAW DFT) method is used, which allows for the prediction and rationalization of the experimental EFG and CS tensor parameters based on the input crystal structure. In the case of 43Ca solid-state NMR experiments reported in this dissertation, a linear correlation between the calculated and experimental 43Ca quadrupolar coupling constants, CQ, is used as a calibration curve for GIPAW DFT calculations performed on the 18 structural models currently available for the vaterite polymorph of CaCO3. Vaterite cannot be fully characterized by X-ray diffraction alone; therefore an NMR crystallography protocol is used in order to identify the model that best accounts for 43Ca solid-state NMR experiments performed on vaterite. It is expected that the conclusions from this dissertation can be used for future studies involving structural refinement and elucidation of solid materials containing challenging quadrupolar nuclei.

Abstract:
Physics<br>Ph.D.<br>The field of condensed matter computational physics has seen an explosion of applicability over the last 50+ years. Since the very first calculations with ENIAC and MANIAC the field has continued to pushed the boundaries of what is possible; from the first large-scale molecular dynamics simulation, to the implementation of Density Functional Theory and large scale Car-Parrinello molecular dynamics, to million-core turbulence calculations by Standford. These milestones represent not only technological advances but theoretical breakthroughs and algorithmic improvements as well. The work in this thesis was completed in the hopes of furthering such advancement, even by a small fraction. Here we will focus mainly on the calculation of electronic and structural properties of solids and liquids, where we shall implement a wide range of novel approaches that are both computational efficient and physically enlightening. To this end we routinely will work with maximally localized Wannier functions (MLWFs) which have recently seen a revival in mainstream scientific literature. MLWFs present us with interesting opportunity to calculate a localized orbital within the planewave formalism of atomistic simulations. Such a localization will prove to be invaluable in the construction of layer-based superlattice models, linear scaling hybrid functional schemes and model quasiparticle calculations. In the first application of MLWF we will look at modeling functional piezoelectricity in superlattices. Based on the locality principle of insulating superlattices, we apply the method of Wu et al to the piezoelectric strains of individual layers under iifixed displacement field. For a superlattice of arbitrary stacking sequence an accurate model is acquired for predicting piezoelectricity. By applying the model in the superlattices where ferroelectric and antiferrodistortive modes are in competition, functional piezoelectricity can be achieved. A strong nonlinear effect is observed and can be further engineered in the PbTiO 3 /SrTiO 3 superlattice and an interface enhancement of piezoelectricity is found in the BaTiO 3 /CaTiO 3 superlattice. The second project will look at The ionization potential distributions of hydrated hydroxide and hydronium which are computed within a many-body approach for electron excitations using configurations generated by ab initio molecular dynamics. The experimental features are well reproduced and found to be closely related to the molecular excitations. In the stable configurations, the ionization potential is mainly perturbed by solvent water molecules within the first solvation shell. On the other hand, electron excitation is delocalized on both proton receiving and donating complex during proton transfer, which shifts the excitation energies and broadens the spectra for both hydrated ions. The third project represents a work in progress, where we also make use of the previous electron excitation theory applied to ab initio x-ray emission spectroscopy. In this case we make use of a novel method to include the ultrafast core-hole electron dynamics present in such situations. At present we have shown only strong qualitative agreement with experiment.<br>Temple University--Theses

Abstract:
A NMR study of the structure-dynamics relationships in heterogeneous materials is presented. In the first part, transport in soft-matter systems is studied using the pulsed field gradient NMR technique (PFG NMR). The molecular crowding effect in biological matter has been addressed using polymer solutions as model systems. By performing ensemble-based diffusion studies, the earlier obtained data on anomalous diffusion have been complemented. The transition to normal diffusion on a larger time scale has been shown. Taking advantages of the NMR approach, transport properties of microemulsions consisting of micellar colloids dissolved in liquid crystals have been investigated. The self-diffusivities measured under equilibrium conditions have shown weak correlations with microscopic ordering and macroscopic phase transitions occurring in the systems under study. The formation of micelles is shown to be decisive for macroscopic separation at the isotropic-nematic transition. The second part of the thesis covers heterogeneous effects in diffusion for fluids in porous solids, as probed using a combination of NMR diffusometry and structure characterization methods. Ionic liquids have been investigated, revealing a complex behavior under confinement. The attempts to correlate the observed characteristics of the ionic liquids with their internal chemical structure were undertaken. Finally, the series of nanoporous glasses with tunable pore structure characteristics were studied. Strong correlations between their structure and the preparation conditions as well as between the resulting transport properties have been shown.

Abstract:
L’un des enjeux pour le développement des batteries tout-solide est d’augmenter la conductivité ionique des électrolytes solides. Le sujet de la thèse porte sur l’étude de deux types de matériaux d’électrolytes solides inorganiques cristallins: les Grenat Li7- 3xAlxLa3Zr2O12 (LLAZO) et les Nasicon Li1.15- 2xMgxZr1.85Y0.15(PO4)3 (LMZYPO). L’objectif de cette étude est de comprendre dans quelle mesure les propriétés conductrices des matériaux étudiés sont impactées par des modifications structurales générées soit par un procédé de traitement particulier, soit par une modification de la composition chimique, et ce grâce au croisement des données structurales acquises par diffraction des rayons X (DRX) et Résonance Magnétique Nucléaire (RMN) MAS avec des données de dynamique des ions déduites de mesures de RMN en température et de spectroscopie d’impédance électrochimique (SIE).Les poudres ont été synthétisées après optimisation des traitements thermiques par méthode solide-solide ou solgel. La densification des pastilles utilisées pour les mesures de conductivité ionique par SIE a été réalisée par la technique de frittage Spark Plasma Sintering (SPS).Dans le cas des grenats LLAZO, l’originalité de notre travail est d’avoir montré qu’un traitement de frittage par SPS, au-delà de la densification attendue des pastilles, engendre également des modifications structurales qui ont des conséquences directes sur la mobilité des ions lithium dans le matériau et par conséquent sur la conductivité ionique. Une augmentation franche de la dynamique microscopique des ions lithium après frittage par SPS a en effet été observée par des mesures en température de RMN de 7Li et le suivi des constantes de relaxation.La deuxième partie de l’étude constitue un travail exploratoire sur la substitution de Li+ par Mg2+ dans LMZYPO. Nous avons ainsi étudié les propriétés de conduction ionique de ces composés mixtes Li/Mg, en parallèle d’un examen minutieux des phases cristallines formées. Nous avons notamment montré que la présence de Mg2+ favorise la formation des phases β’ (P21/n) et β (Pbna) moins conductrices ce qui explique la diminution de la conductivité ionique avec le taux de substitution de Li+ par Mg2+ observée dans ces matériaux de type Nasicon.Nos travaux soulignent donc l’importance primordiale des effets de structure sur les propriétés de matériaux d’électrolytes solides de type céramique<br>One of the issues for the development of all-solid-state batteries is to increase the ionic conductivity of solid electrolytes. The thesis work focuses on two types of materials as crystalline inorganic solid electrolytes: a Garnet Li7-3xAlxLa3Zr2O12 (LLAZO) and a Nasicon Li1.15-2xMgxZr1.85Y0.15(PO4)3 (LMZYPO). The objective of this study is to understand to what extent the conduction properties of the studied materials are impacted by structural modifications generated either by a particular treatment process, or by a modification of the chemical composition. Structural data acquired by X-ray diffraction (XRD) and Magic Angle Spinning (MAS) Nuclear Magnetic Resonance (NMR) were then crossed with ions dynamics data deduced from NMR measurements at variable temperature and electrochemical impedance spectroscopy (EIS).The powders were synthesized after optimizing thermal treatments using solid-solid or sol-gel methods. Spark Plasma Sintering (SPS) technique was used for the densification of the pellets used for ionic conductivity measurements by EIS.In the case of garnets LLAZO, the originality of our work is to have shown that a SPS sintering treatment, beyond the expected pellets densification, also generates structural modifications having direct consequences on the lithium ions mobility in the material and therefore on the ionic conductivity. A clear increase of the lithium ions microscopic dynamics after SPS sintering was indeed observed by variable temperature 7Li NMR measurements and the monitoring of the relaxation times.The second part of the study provides an exploratory work on the substitution of Li+ by Mg2+ in LMZYPO. We studied the ionic conduction properties of these mixed Li/Mg compounds, in parallel with a fine examination of the crystalline phases formed. We have showed in particular that the presence of Mg2+ favors the formation of the less conductive β’ (P21/n) and β (Pbna) phases, which explains the decrease of the ionic conductivity with the substitution level of Li+ by Mg2+ observed in these Nasicon type materials.Our work therefore highlights the crucial importance of structural effects on the conduction properties of ceramic solid electrolyte materials

Abstract:
A framework is proposed for the investigation of chemical and mechanical properties of nanostructures. The methodology is based on a two-step approach to compute the electronic density distribution in and around a nanostructure, and then the equilibrium configuration of its nuclei. The Electronic Problem embeds interpolation and coupled cross-domain optimization techniques through a process called electronic reconstruction. In the second stage of the solution, the Ionic Problem repositions the nuclei of the nanostructure given the electronic density in the domain. The new ionic configuration is the solution of a nonlinear system based on a first-order optimality condition when minimizing the total energy associated with the nanostructure. The overall goal is a substantial increase in the dimension of the nanostructures that can be simulated by using approaches that include accurate DFT computation. This increase stems from the fact that during the solution of the Electronic Problem expensive DFT calculations are limited to a small number of subdomains. For the Ionic Problem, computational gains result from approximating the position of the nuclei in terms of a reduced number of representative nuclei following the quasicontinuum paradigm.

Abstract:
During the past decade zero kinetic energy photoelectron spectroscopy (ZEKE-PES)1 has become one of the most important techniques for gas-phase studies of molecular ions and ionic complexes. Compared to conventional photoelectron techniques a resolution enhancement by 2 to 3 orders has been achieved and even the rotational structure of larger polyatomic ions can be resolved.2

Abstract:
Stimulated Raman Scattering (SRS) in solid state materials is a new extensively growing area in laser physics. SRS allows to change laser radiation frequency with the certain energy shift that is determined by the crystal structure of Raman material. The advantage of solid state Raman material is their high concentration of Raman active centers and their favorable thermal and mechanical properties. There is a limited number of solids that have been identified to possess the narrow, isolated and intense Raman active vibronic modes which are necessary for efficient SRS scattering. Intense modes in solids can be attributed to internal symmetrical vibrations within molecular ionic complexes, such as [CO3], [NO3], [SO4], [WO4] and similar. In spite of a large number of solids which exhibit SRS properties, nitrates of alkaline and alkali-halide metals attract attention as the most promising class of Raman laser media.

Abstract:
The transient waveforms measured in the femtosecond time-resolved, optical heterodyne detected Raman-induced Kerr effect in liquid water (fs OHD-RIKE) are interpreted by the combination of a forced oscillator kinetic analysis and modal decomposition of the depolarized Raman spectrum deduced from a fast Fourier transform analysis of the discreetly sampled experimental observable. We recently presented an analysis of the fs OHD-RIKE dynamics observed in room temperature/atmospheric pressure liquid water accounting for the structural/vibrational dynamics over the inverse frequency range 0-600 cm-1[1].

Full text
Abstract:
Theoretical models and MD simulation studies suggest that dissolved salts tend to alter the surface tension at liquid vapor interfaces and affect the stability of the free liquid film between adjacent bubbles. Recent modeling of the Leidenfrost phenomenon also indicates that bubble merging is a key mechanism affecting the Leidenfrost transition conditions. This investigation summarizes the results of an investigation of the effects of dissolved salts on liquid film stability and bubble merging in the aqueous solution. The interaction of pairs of bubbles injected into solution with different dissolved salt concentrations was studied experimentally to determine the probability of merging from statistics for ensembles of bubble pairs. The results of these experiments indicate that very low dissolved salt concentrations can strongly reduce the tendency of adjacent bubbles to merge, implying that the presence of the dissolved salt in such cases strongly enhances the stability of the free liquid film between adjacent bubbles. The trends are compared to predictions of free liquid film stability by wave instability theory and MD simulations. These trends are also compared to experimental data indicating the effects of dissolved salt on the Leidenfrost transition. These comparisons indicate that the suppression of merging due to the effects of some dissolved salts can significantly alter the Leidenfrost transition conditions. The implications of this in quenching of cast aluminum or steel parts using water of variable hardness are also discussed.
