Abstract:
In this Chapter we review knowledge about diffusion and cation conduction in oxide glasses. We first remind the reader in Section 1 of major aspects of the glassy state and recall in Section 2 the more common glass families. The diffusive motion in ion-conducting oxide glasses can be studied by several techniques – measurements of radiotracer diffusion, studies of the ionic conductivity by impedance spectroscopy, viscosity studies and pressure dependent studies of tracer diffusion and ion conduction. These methods are briefly reviewed in Section 3. Radiotracer diffusion is element-specific, whereas ionic conduction is not. A comparison of both types of experiments can throw considerable light on the question which type of ions are carriers of ionic conduction. For ionic conductors Haven ratios can be obtained from the tracer diffusivity and the ionic conductivity for those ions which dominate the conductivity.In the following sections we review the diffusive motion of cations in soda-lime silicate glass and in several alkali-oxide glasses based mainly on results from our laboratory published in detail elsewhere, but we also take into account literature data.Section 4 is devoted to two soda-lime silicate glasses, materials which are commonly used for window glass and glass containers. A comparison between ionic conductivity and tracer diffusion of Na and Ca isotopes, using the Nernst-Einstein relation to deduce charge diffusivities, reveals that sodium ions are the carriers of ionic conduction in soda-lime glasses. A comparison with viscosity data on the basis of the Stokes-Einstein relation shows that the SiO2 network is many orders of magnitude less mobile than the relatively fast diffusing modifier cations Na. The Ca ions are less mobile than the Na ions but nevertheless Ca is considerably more mobile than the network.Section 5 summarizes results of ion conduction and tracer diffusion for single Na and single Rb borate glasses. Tracer diffusion and ionic conduction have been studied in single alkali-borate glasses as functions of temperature and pressure. The smaller ion is the faster diffusing species in its own glass. This is a common feature of all alkali oxide glasses. The Haven ratio of Na in Na borate glass is temperature independent whereas the Haven ratio of Rb diffusion in Rb borate glass decreases with decreasing temperature.Section 6 reviews major facts of alkali-oxide glasses with two different alkali ions. Such glasses reveal the so-called mixed-alkali effect. Its major feature is a deep minimum of the conductivity near some middle composition for the ratio of the two alkali ions. Tracer diffusion shows a crossover of the two tracer diffusivities as functions of the relative alkali content near the conductivity minimum. The values of the tracer diffusivities also reveal in which composition range which ions dominate ionic conduction. Tracer diffusion is faster for those alkali ions which dominate the composition of the mixed glass.Section 7 considers the pressure dependence of tracer diffusion and ionic conduction. Activation volumes of tracer diffusion and of charge diffusion are reviewed. By comparison of tracer and charge diffusion the so-called Haven ratios are obtained as functions of temperature, pressure and composition. The Haven ratio of Rb in Rb borate glass decreases with temperature and pressure whereas that of Na in Na borate glass is almost constant.Section 8 summarizes additional common features of alkali-oxide glasses. Activation enthalpies of charge diffusion decrease with decreasing average ion-ion distance. The Haven ratio is unity for large ion-ion distances and decreases with increasing alkali content and hence with decreasing ion-ion distance.Conclusions about the mechanism of diffusion are discussed in Section 9. The Haven ratio near unity at low alkali concentrations can be attributed to interstitial-like diffusion similar to interstitial diffusion in crystals. At higher alkali contents collective, chain-like motions of several ions prevail and lead to a decrease of the Haven ratio. The tracer diffusivities have a pressure dependence which is stronger than that of ionic conductivity. This entails a pressure-dependent Haven ratio, which can be attributed to an increasing degree of collectivity of the ionic jump process with increasing pressure. Monte Carlo simulations showed that the number of ions which participate in collective jump events increases with increasing ion content – i.e. with decreasing average ion-ion distance. For the highest alkali contents up to four ions can be involved in collective motion. Common aspects of the motion process of ions in glasses and of atoms in glassy metals are pointed out. Diffusion in glassy metals also occurs by collective motion of several atoms.Section 10 summarizes the major features of ionic conduction and tracer diffusion and its temperature and pressure dependence of oxide glasses.

Abstract:
This review article presents recent studies on nanostructured glass-ceramic materials with substantially improved electrical (ionic or electronic) conductivity or with an extended temperature stability range of highly conducting high-temperature crystalline phases. Such materials were synthesized by the thermal nanocrystallization of selected electrically conducting oxide glasses. Various nanostructured systems have been described, including glass-ceramics based on ion conductive glasses (silver iodate and bismuth oxide ones) and electronic conductive glasses (vanadate-phosphate and olivine-like ones). Most systems under consideration have been studied with the practical aim of using them as electrode or solid electrolyte materials for rechargeable Li-ion, Na-ion, all-solid batteries, or solid oxide fuel cells. It has been shown that the conductivity enhancement of glass-ceramics is closely correlated with their dual microstructure, consisting of nanocrystallites (5–100 nm) confined in the glassy matrix. The disordered interfacial regions in those materials form “easy conduction” paths. It has also been shown that the glassy matrices may be a suitable environment for phases, which in bulk form are stable at high temperatures, and may exist when confined in nanograins embedded in the glassy matrix even at room temperature. Many complementary experimental techniques probing the electrical conductivity, long- and short-range structure, microstructure at the nanometer scale, or thermal transitions have been used to characterize the glass-ceramic systems under consideration. Their results have helped to explain the correlations between the microstructure and the properties of these systems.

Abstract:
Lithium phosphate glass with composition of 45Li2O-55P2O5 (in mol%) was prepared by the conventional melt quenching method and the electrical properties were examined by DC conductivity and impedance spectra. It was found that the difference between DC conductivity and DCtot conductivity deduced from impedance spectra was distinct. Difference of activation energies obtaining by DC and DCtot conductivity implied that the conduction mechanism was different. The glass of 45Li2O-55P2O5 is lithium ion conductor while the oxygen ion in the glass can migrate in some conditions.

Abstract:
L'objectif principal de ce travail est de développer une nouvelle vitrocéramique structurée par NASICON avec une conductivité Li-ion élevée. Par conséquent, ce travail présente une nouvelle série de compositions de type NASICON sur la base du système Li1+xCrx(GeyTi1-y)2-x(PO4)3. Dans un premier temps, une composition spécifique de ce système a été synthétisée par la méthode de fusion et refroidissement rapide, suivie d'une cristallisation. Le comportement de cristallisation du verre précurseur a été examiné par calorimétrie différentielle à balayage et spectroscopie infrarouge. Les principaux résultats indiquent que le verre précurseur présente une nucléation homogène, a une stabilité de verre considérable et cristallise une phase de type NASICON, qui permet d'obtenir des électrolytes solides par voie vitrocéramique. Dans une deuxième étape, on examine l'effet de la substitution de Ti par Cr et Ge sur la stabilité de verre du verre précurseur, sur les paramètres structuraux de la phase cristalline NASICON et sur les propriétés électriques des vitrocéramiques. Par conséquent, un ensemble de seize compositions de ce système est synthétisé. Les principaux résultats indiquent que la stabilité de verre augmente lorsque Ti est remplacé par Ge et Cr. Après cristallisation, toutes les vitrocéramiques présentent une phase de type NASICON, et leurs paramètres de maille décroissent avec Ge et augmentent avec la teneur en Cr, ce qui permet de régler le volume de la cellule unitaire de la structure de type NASICON. De plus, la conductivité ionique et l'énergie d'activation pour la conduction du lithium dans les vitrocéramiques dépendent notamment du volume de la cellule unitaire de la structure de type NASICON. Enfin, la fenêtre de stabilité électrochimique de la vitrocéramique à structure NASICON de conductivité ionique la plus élevée est étudiée. Les mesures de voltampérométrie cyclique sont suivies par spectroscopie d'impédance électrochimique in situ, permettant de déterminer l'effet des réactions d'oxydation et de réduction sur les propriétés électriques des vitrocéramiques en question. La spectroscopie photoélectronique par rayons X, à son tour, est appliquée pour déterminer quelles espèces chimiques subissent une réduction/oxydation. Nos résultats révèlent que la stabilité électrochimique de ce matériau est limitée par la réduction des cations Ti+4 dans les faibles potentiels et par l'oxydation des anions O-2 dans les hauts potentiels. Aux hauts potentiels, un comportement similaire a également été rencontré pour d'autres conduites Li-ion de type NASICON bien connues, suggérant que le comportement électrochimique dans les potentiels oxydatifs pourrait être généralisé pour les phosphates à structure NASICON
The primary goal of this work is to develop a new NASICON-structured glass-ceramic with high Li-ion conductivity. Therefore, this work introduces a new series of NASICON-type compositions based on the Li1+xCrx(GeyTi1-y)2-x(PO4)3 system. At first, a specific composition of this system is synthesized by the melt-quenching method, followed by crystallization. The crystallization behavior of the precursor glass is examined by differential scanning calorimetry and infrared spectroscopy. The main results indicate that the precursor glass presents homogeneous nucleation, has considerable glass stability and crystallizes a NASICON-like phase, which allows solid electrolytes to be obtained by the glass-ceramic route. As a second step, we examine the effect of substituting Ti by Cr and Ge on the glass stability of the precursor glass, on the structural parameters of NASICON-like phase and the electrical properties of the glass-ceramics. Hence, a set of sixteen compositions of this system is synthesized. The main results indicate that the glass stability increases when Ti is replaced by Ge and Cr. After crystallization, all the glass-ceramics present NASICON-like phase, and their lattice parameters decrease with Ge and increase with Cr content, making it possible to adjust the unit cell volume of the NASICON-type structure. Furthermore, the ionic conductivity and activation energy for lithium conduction in the glass-ceramics are notably dependent on the unit cell volume of the NASICON-type structure. Finally, the electrochemical stability window of the NASICON-structured glass-ceramics of highest ionic conductivity is investigated. Cyclic voltammetry measurements are followed by in situ electrochemical impedance spectroscopy, enabling the effect of oxidation and reduction reactions on the electrical properties of the glass-ceramics in question to be determined. X-ray photoelectron spectroscopy, in turn, is applied to determine which chemical species undergo reduction/oxidation. Our findings reveal that the electrochemical stability of this material is limited by the reduction of Ti+4 cations in low potentials and by the oxidation of O-2 anions in high potentials. At high potentials, similar behavior is also encountered for other well-known NASICON-like Li-ion conducting suggesting that the electrochemical behavior in oxidative potentials could be generalized for NASICON-structured phosphates

Abstract:
Fast-ion conducting glasses of the compositions Na1+xM2-x/3SixP3-xOI2-2x3 (0≤ x ≤3), where M = Zr, Ti, were studied to determine their structural arrangement, physical properties and ionic conductivity. Glass samples were prepared using the conventional melt-quench method in the melting temperature range, 1550 °C to 1650 °C. Glass products were characterised by XRD, DTA, dilatometry and density measurement. Solid state MAS NMR experiments of three accessible nuclei, 23Na, 29Si and 31P were used to determine short-range order arrangement in the glasses. XRD confirms the amorphicity of glasses for the compositions of x in range 0-3. Glass transition temperatures, Tg. TEC, and molar volume are controlled by glass composition. The MAS NMR results suggest that glass structure could be visualised as the silicate network modified by Na+ and Zr4+ or Ti4+ and [PO4] tetrahedra link up with the remaining of these modifiers with no Si-O-P observed. The glass structures were also controlled by the compositions. Using parameters determined by DTA, the corresponding glass-ceramics were produced by heat treatment for 4 hr. The composition containing ZrO2 provided the fast-ion conducting crystalline phase at a small concentration. The major crystalline phase is Na2ZrSi2O7. Glass-ceramics containing TiO2 produce very small concentration of the crystallised phase. Ionic conductivity measurement was used to determine the electrical properties of glass and glass-ceramics. Glasses having high Na2O content showed the higher ionic conductivity compared to the others.

Abstract:
Le but de ce travail de thèse a consisté à étudier les propriétés physico-chimiques des verres chalcogénures des systèmes pour pouvoir les utiliser comme les membranes des capteurs chimiques pour le dosage des ions TI⁺ et NA⁺ . D'abord, on a effectué les mesures des propriétés macroscopiques telles que les densités et les températures caractéristiques (Tg, Tc, Tf) et leur analyse selon les compositions des verres. Après, les propriétés de transport ont été étudiés à l'aide de la spectroscopie d'impédance complexe ou par les mesures de la résistivité. Il a été ainsi montré l'effet de cation mixte pour les trois systèmes vitreux avec les ions TI/Ag et le régime de la percolation dans le système NaCl-Ga₂S₃-GeS₂ . Puis, on a réalisé les mesures de diffusion par traceur ¹⁰⁸mAg et ²⁰⁴TI pour le système (TI₂S)ₓ(Ag₂S)₅₀₋ₓ(GeS)₂₅(GeS₂)₂₅. Les résultats ont permis d'expliquer l'effet de cation mixte. Afin de mieux comprendre les phénomènes de transport des systèmes étudiés, diverses études structurales ont été déployées par spectroscopie Raman, diffusion de neutrons et diffraction de rayons X haute énergie. Enfin, la dernière partie de ce travail est entièrement consacrée à la caractérisation de nouveaux capteurs chimiques pour la détection des ions TI⁺ et NA⁺ en solution. Dans le premier cas, les électrodes sélectives aux ions TI⁺ avec les différentes compositions de membrane ont été testées afin de définir la sensibilité, la limite de détection, les coefficients de sélectivité en présence d'ions interférents, la reproductabilité, l'influence de pH. En plus, il était effectué l'échange des traceurs ²⁰⁴TI entre la solution et les verres à base des matrices GeS₂ et Ge₂S₃ pour comprendre et expliquer les différences significatives dans la sensibilité et la limite de détection présentés par les capteurs dont les membranes ont la composition de verre similaire. Dans le deuxième cas, les études montrent l'existence de la sensibilité aux ions NA⁺ donc le développement des capteurs pour le dosage des ions de sodium est possible
The aim of this thesis was to study the physicochemical properties of the chalcogenide glasses for possibility to use them as the chemical sensor membranes for the quantitative analysis of TI⁺ and NA⁺ ions. Firstly, the measurements of the macroscopic properties such as the densities and the characteristic temperatures (Tg, Tc, Tf) and their analysis according to the glass compositions were carried out. After that, the transport properties were studied through complex impedance conductivity measurements and from dc conductivity measurements. These experiments have shown the mixed cation effect in three chalcogenide glassy systems with TI/Ag ions and the percolation regime in the NaCl-Ga₂S₃-GeS₂ system. Then the silver ¹⁰⁸mAg and thallium ²⁰⁴TI tracer diffusion measurements were carried out for (TI₂S)ₓ(Ag₂S)₅₀₋ₓ(GeS)₂₅(GeS₂)₂₅ system. The result permit to explain the mixed cation effect. In order to better understand the transport phenomena of the studied systems, the various structural studies have been deployed using Raman spectroscopy, neutron diffraction and high energy X-ray diffraction. Finally, the last part of this work is entirely devoted to the characterization of new chemical sensors for detection of TI⁺ and NA⁺ ions in solution. In the first case, the sensors with different membrane compositions were tested for defining the sensitivity, the detection limit, the selectivity coefficients in the presence of interfering ions, the reproductibility, the pH influence. In addition, the ionic exchange with radioactive isotopes ²⁰⁴TI between the solution and the GeS₂ or Ge₂S₃ based glasses was performed for understanding and explaining the significant differences in the sensitivity and the detection limit presented by the sensors whose membranes have the similar glass compositions. In the second case, the studies shows the existence of sensitivity for NA⁺ ions so the development of sensors for the determination of sodium ions is possible

Abstract:
L'objectif de ce travail a consisté à identifier des polluants émergents dans des eaux usées issues de stations d'épuration ainsi que dans le milieu naturel et à proposer une méthode de remédiation et un suivi de ces polluants. Dans un premier temps, nous avons identifié les polluants organiques contenus dans les échantillons d'eaux usées et issues du milieu naturel par chromatographie en phase liquide ou gazeuse couplée à une spectrométrie de masse, chromatographie en phase gazeuse par espace de tête statique et par spectrométrie par torche à plasma couplée à une spectrométrie de masse. Différents polluants ont été trouvés tels que les phtalates, des substances médicamenteuses, le cholestérol et des éléments de traces métalliques. Dans le but de piéger ces polluants, différents polymères de cyclodextrine (CD) solubles et insolubles dans l'eau ont été synthétisés et leurs capacités d'adsorption ont été évaluées. Après adsorption sur les polymères de CD, nous avons observé une diminution de la teneur en carbone organique total (COT) de l'effluent. Ces polymères se sont révélés être des adsorbants efficaces. Dans un second temps, des verres du système pseudo-ternaire Agl-HgS-As₂S₃ ont été synthétisés en ajoutant le composé le composé Agl dans le système pseudo-binaire HgS-As₂S₃. Ces verres de chalcogénures sont des membranes ionosélectives permettant de détecter les ions Hg²⁺ dans les effluents. Tout d'abord, nous avons défini le domaine vitreux des verres à l'aide de la diffraction des rayons X, ensuite les propriétés macroscopiques des verres ont été déterminées. Ainsi, les propriétés de transport ont été étudiées à l'aide de la spectroscopie d'impédance complexe montrant que l'ajout d'Agl dans le verre pseudo-binaire HgS-As₂S₃ provoque une augmentation de la conductivité ionique. Afin de comprendre ce phénomène, diverses études structurales ont été déployées par spectroscopie Raman, diffraction de neutrons et de rayon X haute énergie. Ces techniques ont montré que l'évolution de la conductivité ionique est dépendante de la structure du verre qui forme des chemins préférentiels de conduction. Enfin, différents capteurs avec différentes compositions sont testés afin de définir la sensibilité, la limite de détection et les coefficients de sélectivité en présence d'ions interférents
The aim of this work was to identify the emerging pollutants in the effluents of wastewater treatment plants as well as in the natural environment, and to propose a method of remediation and monitoring of these pollutants. In the first part of the thesis, we have identified the organic pollutants contained in the wastewater samples using (i) gas and/or liquid chromatography coupled with a mass spectrometry, (ii) static-headspace gas chromatography, and (iii) inductively coupled plasma atomic emission spectroscopy. Different pollutants were found such as phthalates, drugs, cholesterol, and heavy metal traces. In order to trap these pollutants, various water soluble/insoluble cyclodextrin β-CD polymers have been synthesized and their adsorption capacities were evaluated. After the analysis of the effluent samples, we observed a decrease of the Total Organic Carbon (TOC). This decrease was attributed to the adsorption of pollutant by CD polymers which have proven to be effective adsorbents. The second part of the thesis included two main sub-parts : (i) a synthesis and characterization part and (ii) an application part. In the first sub-part, chalcogenide glasses in the pseudo-ternary Agl-HgS-As₂S₃ system have been synthesized by adding silver iodide "Agl" to the quasi-binary HgS-As₂S₃ system. The vitreous domain and the macroscopic properties of glass samples were determined. Electrical conductivity of glasses was studied using both the complex impedance spectroscopy and resistivity measurements ; it was found that adding Agl to the quasi-binary HgS-As₂S₃ alloy causes an increase in the ionic conductivity. Structural studies, using various techniques as Raman spectroscopy, neutron scattering and high-energy X-ray diffraction, have been performed in order to decipher the relation between both structural and transport properties in these glasses. In the second sub-part, the obtained glasses in the ternary system were used as membranes in chemical sensors dedicated to mercury detection in aqueous solution. As a result, various sensors with different compositions were tested to determine their corresponding sensitivity, detection limit and selectivity coefficients in the presence of interfering ions

Abstract:
Horror cinema grants bodies and images a precarious hold on sense and order: from the zombie’s gory disintegration to the vampire’s absent reflection and from the shaky camerawork of ‘found footage’ horror to the spectacle of shattering glass in the Italian giallo. Addressing classic horror movies alongside popular and innovative contemporary works, Visceral Screens shows how they have rendered the human form as a type of ‘image-body’, mediated by optical effects, chromatic shifts, glitches and audiovisual fragmentation. The question of signification is central to this metaphorical exchange, since horror frequently pushes both bodies and media to the limits of their expressive capacity. Conducting their own anatomies of the screen, cutting across bodies and media alike, horror films revel in the breakdown of frames, patterns and figures, exposing the seams between matter and meaning.

Abstract:
Diffusion of atoms, molecules, and ions control many processes in glasses, including ionic diffusion, ion exchange, electrical conduction, chemical durability, gas permeation, and permeation-controlled reactions. Since the mechanisms underlying all of these processes are based on similar principles, a fundamental understanding of diffusion phenomena serves as the basis for understanding all diffusion-controlled properties of glasses.

Abstract:
In the present research work, melt-quench technique was employed for synthesis of Nd2O3 doped lithium borosilicate glasses having general system 30Li2O- (70-x) [1/7SiO2:6/7B2O3]-xNd2O3. Electrical conductivity of produced samples was tested in frequency band of 2mHz to 20MHz at 423K to 673K, using Impedance Analyser. Impedance data was used for scaling which shows that the process of conduction is based on the composition and not on the temperature. The inclusion of neodymium oxide in the lithium borosilicate glass affects molar volume, density and various physical properties like Ion concentration, ionic radius. The electrical modulus data obtained from impedance analyser was utilized to study relaxation behaviour of the samples. In the temperature band, 423-673 K, the variance of the dielectric loss (Tan δ), dielectric constant (ε’) and ac conductivity (σ’) with frequency was measured using impedance spectroscopy and discussed at length.

Abstract:
Bulk chalcogenide glass semiconductors have been shown to exhibit a large, yet fast absorption nonlinearity.1 The greatly broadened absorption edge characteristic of these amorphous semiconductors offer the possibility for large dynamic optical nonlinearities over a much larger range of wavelengths than found in crystalline materials. In addition, amorphous semiconductors are attractive for optical device applications because they can be deposited easily on a variety of substrates. Thin films of amorphous arsenic sulfide, a chalcogenide glass semiconductor, have been deposited on quartz and silicon substrates by ion beam sputtering. This method of deposition produces films which are amorphous, smooth, and of excellent optical quality. Preliminary measurements using a cw pump-probe technique show that, unlike in crystalline materials, where bandfilling effects cause a decrease in absorption, the absorption increases with pump intensity over a broad range of probe wavelengths. As in the bulk,1 the mechanism responsible for this effect is believed to be a result of structural disorder. Intraband transitions of a type forbidden in crystalline materials cause an increase in absorption at low energies when conduction band tail states are filled by bandgap energy radiation. Quantitative measurements of the change in the absorption spectrum of these films as a function of pump intensity and pump wavelength are presented.

Abstract:
Recently, electrochromic thin films and thin film devices have attracted more and more interest because of strong possibility to act as smart windows and smart glass that may be widely used in the daily life[1]. The electrochromic thin film devices usually have a five layers structure: an actual electrochromic layer, an ionic conductor and an ion storage layer are sandwiched between two outer transparent electrical conductive layers, WO3 film is used as the actual electrochromic films in the general studies. The coloration and bleaching are accomplished when positive ions (Li+, H+ etc. )are moved from the ion storage, via the ionic conductor, into the electrochromic layer, or in the inverse direction. Currently, the electrochromic thin films or thin film devices are characterized by electrochemical analysis and optical spectral transmittance measurement. In fact, the electrochromic effect is a spectral absorption modulation, the investigation of the optical absorption variation during the electrochromic process may offer us more information about the process.

Abstract:
We developed two types of polyatomic cluster ion sources, one of which was a liquid cluster ion source using organic materials with a high-vapor pressure. Vapors of liquid material such as ethanol and water were ejected through a nozzle into a vacuum region, and liquid clusters were produced by an adiabatic expansion phenomenon. Another type was a cluster ion source using ionic liquids with a relatively low-vapor pressure. Positive and negative cluster ions were produced by a high-electric field emission. In addition, the interaction of polyatomic cluster ions with solid surfaces such as Si(100), SiO2, glass, and PMMA surfaces was investigated, and chemical sputtering was predominant for the Si(100) surfaces irradiated by ethanol cluster ion beams. Also, the irradiation damage of the Si(100) surfaces by ethanol and water cluster ion beams was smaller than that by Ar monomer ion irradiation at the same acceleration voltage. With regard to surface modification, PMMA surfaces were chemically modified by water cluster irradiation. Also, glass surfaces changed to electrically conductive surfaces by ionic liquid cluster ion irradiation. Furthermore, to demonstrate engineering applications of high-rate sputtering and low-damage irradiation by ethanol cluster ion beams, micro-patterning was performed on the Si surfaces.

Abstract:
A novel interaction was observed in cadmium-alumino fluorosilicate glasses when exposed to near UV radiation. Glasses high in cadmium were observed to be photochromic. Accompanying the darkening process was a change of up to five orders of magnitude in the DC conductivity. The process involved the formation of the cadmous ion (Cd+1) as an electron trap. A thin, transparent conductive skin could also be formed by appropriate heat treatments.
