Abstract:
The Environmental Scanning Electron Microscope (ESEM) is capable of image generation in a gaseous environment at sample chamber pressures of up to 20 torr. in an ESEM, low energy secondary electrons emitted from a sample surface, by virtue of the primary electron beam, are accelerated towards the positively biased metallic ring (typically +30 to +550V) Gaseous Secondary Electron Detector (GSED). As these electrons accelerate towards the ring they undergo ionizing collisions with gas molecules producing positive ions and additional electrons known as environmental secondary electrons. The environmental electrons further ionize the gas on their way to the ring producing a cascade amplification of the original signal. The amplified signal induced in the ring is used to form an image. The electric field generated between the GSED ring and the grounded stage causes the positive ions produced in the cascade to drift towards the sample, effectively neutralizing negative charge build up on the surface of a non-conducting sample.

Two strategies have been carried out in parallel : one which consists to synthesize interpenetrating networks (IPNs) based on a cellulose derivative and a poly (ethylene oxide) swollen in an exogenous IL ; the other, more innovating, consists in the elaboration of IPNs based on polymerisable ionic liquids. The mechanical and ionic conducting properties of those new materials have been investigated.

Abstract:
Les investigations réalisées au sein du tertiaire Bi2O3-M2O3-Pb0 ont permis la mise en évidence d'une solution solide de symétrie cubique à faces centrées, lacunaires en ions O2, de type delta-Bi2O3. Par trempe à l'air, celle-ci peut être préservée à température ambiante dans un large domaine de composition. La diffraction x en fonction de la température a permis de montrer que, pour des concentrations en Y3+ et Pb2+ suffisante, la structure delta Bi2O3 était conservée lors du chauffage jusqu'au domaine d'équilibre à haute température. Il existe cependant une rupture de pente sur la courbe de variation du paramètre de maille, caractérisant l'existence d'un léger réarrangement structural. Les mesures de conductivité électrique et de nombre de transport des ions O2 ont permis de mettre en évidence une conductivité anionique importante (sigma=0,43 /ohm /xcm pour Bi1,53Pb0,27Y0,2O2,622 à 720°C). L'évolution de la conductivité en fonction de la température est en bon accord avec la présence de deux variétés de la solution solide delta. L'effet potentialisateur de Pb2+ a été mis en évidence par l'augmentation de la conductivité et de la stabilité lorsque le rapport Pb2+/(Pb2+ + Y3+) s'accroit. Une étude du système Bi2O3-Sm2O3-Pb0, a permis également de mettre en évidence une solution solide de type delta-Bi2O3. Alors que le domaine de trempe est un peu plus étendu qu'avec Y2O3, le sous-domaine au sein duquel les échantillons gardent au chauffage la structure delta est beaucoup plus restreint. L'évolution relative de sigma en fonction de la composition reflète celle rencontrée au sein du précèdent système

Abstract:
Ce travail a pour objectif l’étude de matériaux hybrides poreux de type Metal-Organic Frameworks (MOFs) et d’un cristal moléculaire en tant que conducteurs ioniques solides pour des applications dans le domaine de l’énergie et de l’environnement. Dans le premier cas, nous avons développé diverses stratégies pour optimiser et contrôler la teneur en sites acides de Lewis et en porteurs de charges de deux séries de MOFs afin de concevoir des matériaux aux propriétés de conduction protonique très prometteuses. A partir d’une approche basée sur la substitution progressive des ligands par des entités fonctionnalisées présentant des sources de protons acides, nous avons créé une série de MOFs, MIP-207-(SO3H-IPA)x-(BTC)1–x, dont la teneur en groupements sulfoniques, par l’intermédiaire du ligand SO3H-IPA, est contrôlée à façon. Le meilleur matériau qui combine stabilité structurale et conduction protonique élevée présente des performances sous humidité parmi les plus intéressantes au sein de la famille des MOFs conducteurs protoniques (e.g., σ = 2.6 × 10–2 S cm–1 à 363 K/95% d’humidité relative (RH)). Selon une autre approche, nous avons étudié un MOF mésoporeux connu (MIL-101(Cr)-SO3H) dont les parois des pores sont tapissées de sites protoniques et qui contient dans ses pores un liquide ionique, le chlorure chlorure de 1-Ethyl-3-methylimidazolium (EMIMCl) capable d’assurer le transfert de proton. L’encapsulation du liquide ionique, caractérisée par une série d’outils expérimentaux (sorption de diazote, DRX sur poudre, TGA/MS, DSC et analyse élémentaire), s’avère particulièrement efficace pour exalter les propriétés de conduction protonique des composites à la fois à l’état anhydre (σ473 K = 1.5 × 10-3 S cm-1) mais également à l’état hydraté (σ(343 K/60%-80%RH) ≥ 0.10 S cm-1). Enfin, ce travail a été étendu à une autre famille de solides poreux, à travers l’étude des propriétés de conduction ionique d’un cristal moléculaire à base de zirconium (Zr-3) qui contient des paires ioniques KCl. Nous avons démontré que ZF-3 transite d’un comportement isolant à l’état anhydre (σ = 5.1 x 10-10 S cm-1 à 363 K/0% RH) vers un comportement super-conducteur ionique en présence d’eau (σ = 5.2 x 10-2 S cm-1 à 363 K/95 % RH), suite à l’augmentation de la dynamique de ions Cl- sous hydratation. Par ailleurs, des simulations moléculaires ont permis de décrire les mécanismes microscopiques à l’origine des propriétés de conduction des matériaux étudiés. Ces avancées devraient permettre de développer dans le futur de nouveaux matériaux performants dans le domaine de la conduction protonique et ionique<br>The conductivity performance of a new series of chemically stable proton conducting Metal Organic Frameworks (MOFs) as well as a superionic molecular crystal was explored. The contribution of this PhD was to (i) select a variety of architectures and functionalities of robust MOFs/superionic molecular solids and (ii) characterize and rationalize their conducting performance over various temperature/humidity conditions. We designed two series of MOFs to achieve promising proton-conducting performance, using distinct approaches to modulate the concentration of Brønsted acidic sites and charge carriers and further boost the conductivity properties. First, a multicomponent ligand replacement strategy was successfully employed to elaborate a series of multivariate sulfonic-based solids MIP-207-(SO3H-IPA)x-(BTC)1–x which combine structural integrity with high proton conductivity values (e.g., σ = 2.6 × 10–2 S cm–1 at 363 K/95% Relative Humidity -RH-). Secondly, a proton conducting composite was prepared through the impregnation of an ionic liquid (1-Ethyl-3-methylimidazolium chloride, EMIMCl) in the mesoporous MIL-101(Cr)-SO3H. The resulting composite displaying high thermal and chemical stability, exhibits outstanding proton conductivity not only at the anhydrous state (σ473 K = 1.5 × 10-3 S cm-1) but also under humidity (σ(343 K/60%-80%RH) ≥ 0.10 S cm-1) conditions. Finally, the ionic conducting properties of another class of porous solids, considering a zirconium-formate molecular solid containing KCl ion pairs (ZF-3) were explored. ZF-3 switches from an insulator (σ = 5.1 x 10-10 S cm-1 at 363 K/0% RH) to a superionic conductor upon hydration (σ = 5.2 x 10-2 S cm-1 at 363 K/95 % RH), in relation with the boost of Cl- dynamics upon water adsorption. Noteworthy, quantum- and force-field based simulations were combined with the experimental approach to elucidate the microscopic mechanisms at the origin of the ionic conducting properties of the studied materials. This fundamental knowledge will serve to create novel robust superionic conductors with outstanding performances that will pave the way towards appealing societal applications for clean energy production

Abstract:
Abstract In Group IV bulk semiconductors such as Si, it is possible to replace some of the atoms in the lattice by impurity atoms belonging to group V of the periodic table, such as P. The group V impurity atom has an additional electron which is not used in the covalent bonding in the crystal. Due to the effective dielectric constant of the host and its reduced effective mass the electron is weakly bound to the impurity atom forming a hydrogenic structure. In III---V compound semiconductors such as GaAs an analogous impurity doping can be accomplished by using Si which replaces a Ga atom in the GaAs lattice. These impurity atoms, called donors, ionize easily, giving off the bound electron to enable electrical conduction; the binding energy of an Si donor in GaAs is about 5 meV. The conduction is limited by scattering from the ionized impurity atoms, besides other scattering mechanisms. With the advent of molecular beam epitaxy (MBE) it was recognized that the conduction channel and the location of impurity doping can be separated to improve the mobility of carriers. With the remarkable control over the composition and almost atomic perfection in the heterostructure crystals grown by MBE, a quantum well structure can be grown with selective doping only in specified sections of the barrier regions. If the barrier regions alone are doped with impurity atoms, the electrons initially bound to the impurity atoms seek lower energy states and fall into the quantum well. This reduces their probability of being in the barrier region with the ionized impurities, resulting in a reduction in ionized impurity scattering in transport in the in-plane direction. This selective doping of the barrier, or any particular layer for that matter, is called modulation doping.

Abstract:
We report the observation of a new avalanche phenomenon in superlattices. This effect is characterized by a large ratio of the multiplications for holes and electrons implying β ≫ α and is very different in nature from the previously studied band-edge discontinuity assisted ionization in quantum wells. The i region of our p+in+ structures, grown by MBE, consists of an undoped (n ≃1015 cm−3) Al0.48ln0.52As/Ga0.47ln0.53As superlattice. Six wafers with well and barrier thicknesses ranging from 100 to 470 Å and a number of periods varying from 20 to 50 were studied. In addition similar MBE structures with an AISb/GaSb superlattice were also grown. The electron and hole initiated gains (Me and Mh) were determined using standard techniques. It was found that Mh ≫ Me. Ionization ratios β/α in excess of 102 have been deduced which are the highest observed in any III–V material. All the experimental data can be explained in terms of a new mechanism, impact ionization across the band-edge discontinuity. There are concentrations of electrons and holes dynamically stored in the conduction and valence band wells which can easily approach 1016 cm−3 in our structures, at fields ≲ 105 V/cm. Consider now a carrier (e.g., a hole) photoinjected into the structure; after gaining energy in the barrier layers it can impact-ionize one of the holes dynamically stored in the low gap layers out of the well across the valence band discontinuity. Electrons may of course impact-ionize electrons out of the wells but since ∆EC(≃0.5 eV) is more than twice ∆Ev, the electron ionization rate is much smaller than the hole ionization rate which explains why the holes are multiplied much more than the electrons. New solid-state photomultipliers based on this phenomenon are discussed.

Abstract:
Ionizing radiation, when it hits our bodies, can ionize and excite the atomic nuclei of cells. Ionization and excitation will cause DNA damage either directly or indirectly. DNA damage is direct if ionizing radiation hits DNA, while DNA damage is indirectly through the formation of free radicals (atoms with unpaired electrons) and has a very damaging effect on DNA. Therefore, safety in ionizing radiation, including its use in the medical world, is essential. Protection includes safety avoiding deterministic effects and stochastic effects. To protect against both deterministic and stochastic effects, the role of the radiographer is significant. Heinrich (1980) estimates that (85%) accidents are the result of the contribution of unsafe work behavior (unsafe act). Radiation accidents reported by the United States Energy Atomic Commission from 1960-1968 were caused by operator error (68%), procedural errors (8%), equipment damage (15%), and others (9%). When viewed in detail, the operator's errors were not conducting a radiation survey (46%), not following procedures (36%), not using protective equipment (6%), human error (6%), and calculating radiation exposure errors (6%). Therefore, the radiographer must know and understand ionizing radiation, its dangers, and the application of radiation protection from the results of a survey conducted at Prof. Hospital. Dr. Margono Soekarjo Purwokerto to 22 radiographers showed that the level of understanding of ionizing radiation, the dangers, and the application of radiation protection is still low. Therefore education and training are very much needed for them. Keywords: Radiation Hazard, Radiation Protection, Radiographer Education and Training

Abstract:
Mental health is becoming increasingly important in today's society. More and more people are turning to mindfulness exercises, relaxation techniques, and sports to unwind, alleviate stress, and enhance resilience. However, amidst the stress of daily life and the constant demands of work, family, and leisure activities, many individuals still struggle to find time to nurture their mental well-being. An often-overlooked opportunity to do so lies in daily commuting. In German cities, daily commute times can reach up to 60 minutes due to traffic jam and heavy traffic. This time can be used more effectively, especially with the increasing automation of vehicles, to focus on the personal health. In order to investigate this potential, an innovative multisensory experience was developed for the vehicle interior of a ride-hailing vehicle to promote mental health. This experience was implemented in a real vehicle and examined for its efficacy in a user study. To shape the experience, insights from psychology, environmental psychology, and design research were combined to respond to the passenger's emotional and physical states during the journey. The approach is based on chromotherapy, where different light colors and intensities are used to reduce physical and mental illnesses. Furthermore, an acoustic guidance for a breathing exercise, based on the success of Pranayama practice, was developed to be practiced simultaneously by the passenger, along with a haptic element on the belt, which further enhances the emotions during the experience. The immersive experience is individualized based on an analysis of the LIMBIC types, i.e. personality models, in order to achieve the greatest possible relaxation effect.The research methodology included comprehensive literature review on existing concepts and technologies, expert interviews with both light and sound designers as well as psychologists, and two quantitative user surveys to gather requirements and define specific design elements of a holistic immersive experience. Based on the preliminary work and findings of a previous study on light combined with a breathing exercise to enhance mental health, a multisensory concept was developed and integrated into a Hyundai Ioniq 5. To achieve this, legroom on the rear bench was expanded, the driver's cabin was shielded, flexible LED panels were attached to the back of the front seats, and a 360-degree sound system was integrated. Additionally, a belt concept was designed, equipped with vibration sensors that can transmit controlled haptic impulses to the passenger during the journey. To test the success of the designed experience, a qualitative user study was conducted with 12 participants. For this purpose, a travel scenario was recreated, which all passengers had to go through. Before and after the journey, the participants were interviewed about their well-being during the entire testing period. In parallel, the vital data heartbeat and electrodermal activity were collected through a wearable device (wristband) in order to compare them with the personal assessments. The results of the ongoing study will be presented in the full paper. In summary, based on the previous interviews and quantitative user studies, there is a need for applications to improve mental health. There is also a demand to use commuting times more effectively for personal well-being, particularly in the future with automated driving.
