Full textDenna avhandling behandlar tillverkning av medicinska implantat för integration i ben. I fokus är den additiva tillverkningstekniken ”elektronstrålesmältning” ( Electron Beam Melting –EBM), en av flera tekniker som populärt beskrivs med termen 3D-skrivare. Avhandlingen fokuserar på mikroskopiska ytegenskaper och dess inverkan på benintegration. Processparametrarna för EBM-tillverkning studerades för att fastställa hur de påverkar ytans utseende, efter som ytegenskaper har effekt på implantatens funktion. EBM-tillverkning använder en elektronstråle som likt svetsning smälter ihop metallpulver. Elektronstrålen styrs av processparametrar som till viss mån kan justeras av maskinoperatören. Det finns individuella processparametrar för varje material och nya parametrar utvecklas till varje ny legering. I denna avhandling har ”grundinställningarnas processparametrar” studerats för att ta reda på om det är möjligt att ställa in specifika parametrar till implantattillverkning. Med hjälp av blodkammarmetoden, som använder humant blod, har thromboinflammatoriska egenskaper undersökts. Metoden identifierar tidiga koagulations- och immunologiska reaktioner. Legeringarna som undersökts i denna studie var Ti6Al4V-ELI, som är korrosionsbeständigt med samma uppsättning oxider på ytan som titan har, och CoCr-F75, en legering som har hög styvhet, är slitstarkt och är vanligt förekommande i implantat för leder. Bland de undersökta processparametrarna visar en kombination av hastighet och ström ha mest inverkan på ytjämnhet och en interaktion mellan parametrar identifierades med hjälp av försöksplanering. EBM-tillverkade ytor visade på thrombogena egenskaper som i tidigare studier kan relateras till god integration i benvävnad. Ytstrukturen hos EBM-tillverkade ytor liknar de implantatytor som Pilliar (2005) beskriver, men materialegenskaperna är bättre än de materialegenskaper som implantat, med sintrad yta, har. Genom att ändra processparametrarna som styr elektronstrålen kan ytstrukturen påverkas. Grövre EBM-tillverkade ytor tenderar att vara mer thrombogena än de finare EBM-tillverkade ytorna är. Obehandlade EBM-tillverkade ytor i allmänhet är mer thrombogena än vad konventionellt framställda implantatytor är.

Full textAdditive Manufacturing (AM) techniques based on powder bed fusion like Selective Laser Melting(SLM) and Electron Beam Melting processes(EBM) are being developed to make fully functional parts mainly in aerospace and medical sectors. There are several advantages of using AM processes like design freedom, reduced process steps, minimal material usage and reduced carbon footprint while producing a component. Nevertheless, the parts are built with near net shape and then finish machined to meet the demands of surface quality and dimensional tolerance

Full textThe present work describes the use of atomistic computer simulations in the area of Condensed Matter Physics, and specifically its application to the study of two problems: the dynamics of the melting phase transition and the properties of materials at extreme high pressures and temperatures, problems which defy experimental measurements and purely analytical calculations.
Both classical Molecular Dynamics (using semi–empirical interaction potentials) and first–principles (ab initio) Molecular Dynamics techniques has been applied in this study to the calculation of melting curves in a wide range of pressures for elements such as Xe and H2, the study of the elastic constants of Fe at the conditions of the Earth’s inner core, and the characterization of diffusion and defects formation in a generic Lennard–Jones crystal at the limit of superheating, including the role they play in the triggering of the melting process itself.

Full textDeoxyribonucleic acid (DNA) self-assembled monolayers (SAMs) immobilized on gold electrodes are the basis of many electrochemical biosensors. Control of the interfacial behavior of DNA by means of an electric field is of interest for sensing applications such as the detection of single nucleotide polymorphisms (SNPs). Moreover, the in situ characterization of immobilized DNA monolayers at a molecular level is important for the fabrication of robust, reliable and sensitive sensors.The thesis aims at studying the discrimination between DNA strands containing SNPs on the basis of electric-field assisted hybridization/denaturation of DNA. In situ electrochemical fluorescence microscopy is used as a detection methodology and characterization tool for DNA interfaces. For this purpose, fluorescently labeled DNA sequences are immobilized at gold electrodes as thiol SAMs.First, the SAMs under investigation were composed of perfect match or SNP-containing target sequences. The relationship between the applied potential and the denaturation of DNA duplexes was investigated. Electrochemical melting was observed at -0.25 V vs. Ag

"Variabilité atmosphérique en Antarctique de l'Ouest : Impact sur la circulation océanique et sur le bilan de masse de surface de la calotte Interannual Variability of Summer Surface Mass Balance and Surface Melting in the Amundsen Sector, West Antarctica." Thesis, Université Grenoble Alpes (ComUE), 2019. http://www.theses.fr/2019GREAU032.
Full textWest Antarctica, and particularly the Amundsen sector, has shown since the 1990s a large increase of mass loss related to coastal glacier acceleration in response to an increase of oceanic melt underneath ice shelves. Ice shelves play a buttressing role for ice-stream and increased oceanic melt therefore lead to ice shelves thinning and glacier acceleration, which contributes to sea level rise. West Antarctica is of particular concern because its configuration is prone to marine ice-sheet instability. It has been suggested that ice shelves weaken under large surface melt in a warmer climate (hydrofracturing), possibly leading to another kind of instability. Instabilities could be slowed down or compensated by future Surface Mass Balance (SMB) that consists mainly of snowfall, sporadic rainfall, and is slightly reduced by sublimation and runoff. The main objective of this PhD work is to model the atmospheric and oceanic processes that will most likely affect the future West Antarctic contribution to sea level rise.First, oceanic projections have been developed using the NEMO ocean model. The ocean circulation induced by ice-shelf basal melting affects the ocean response to future changes in surface winds. Therefore, models that do not represent ice-shelf cavities produce wrong warming patterns around Antarctica. A positive feedback between oceanic melting and grounding-line retreat has been identified and can increase melt rates by a factor of 2.5. These results are strong incentive to couple ocean and ice sheet models, although the projections proposed here are relatively idealized.To run SMB and surface melting projections, an atmospheric model with a fine representation of polar processes, including those related to the snowpack, is needed. MAR is found to be an appropriate tool to simulate the present-day surface climate in the Amundsen region. We find that none of the large climate modes of variability (ASL, SAM, ENSO) explains more than 50% of surface melt and SMB summer variance at the interannual timescale. The use of climate mode variability projections to estimate the future surface climate of West Antarctica is therefore not trivial.Forced by the CMIP5 multi-model mean under the RCP8.5 scenario, MAR predicts an increase of SMB by 30-40% for the end of the 21st century. This increase corresponds to 0.33 mm yr-1 of sea level drop down, which is higher than the current West Antarctic contribution of ~0.26 mm yr-1 from ice dynamics. Surface melt is also projected to increase by a factor of 5 to 15 over the Amundsen ice shelves, but most of it is projected to refreeze in the annual snow layer, so future melting should not have a strong contribution to SMB or hydrofracturing.To conclude we show that coupled ocean and ice sheet climate models are essential to simulate the future of Antarctica and Southern Ocean. A fine representation of surface melt and refreezing processes within the snowpack is also crucial as possible hydrofracturing is threatening in a warmer climate and it comes within a delicate equilibrium between snowfall, air temperature, and feedback related to albedo and humidity

Full textAptamers are single-stranded DNA (ssDNA) or RNA molecules capable of binding to target molecules, including proteins, metal ions and drugs. Because of their specific binding abilities and many advantages over antibodies (higher stability, lower cost, easy chemical modification…), they provide a great opportunity to produce sensing surfaces for effective and selective detection of small molecules. Surface Plasmon Resonance imaging (SPRi) has become one of the most widely used label-free method for the study of biorecognition events on sensor surfaces. This technique provides a rapid approach, however, limited by low refractive index changes occurring when small molecules (<2000 Da) are captured on the sensor. Whereas significant reflectivity variation is observed upon the interaction of large molecules like proteins with the sensing interface, for small molecules targets such adenosine, the reflectivity variation is often too small to be detected by SPRi. Thereby, only few studies have been reported so far on SPRi-based biosensor for small molecules detection using aptamers. In this work, we developed two bioassay strategies for the detection of a model small molecule, adenosine, using Surface Plasmon Resonance imaging. The first one combines the SPRi signal enhancement effect induced by gold nanoparticles (AuNPs) with the advantage of using engineered DNA aptamers. The experimental results have demonstrated that the presence of gold nanoparticles and adenosine, which works as a molecular linker between engineered aptamer fragments, can significantly increase the SPRi response. The second strategy is based on the thermodynamics of binding between adenosine and its aptamer. To that end, SPRi technique was coupled with rigorous temperature control and aptamer duplex stability was monitored (affected by target binding) by quantification of melting transitions. Our results initiate a new approach for small molecule detection using SPRi with the aim to validate future prospects for integration in parallelized platform

Hemette, Sylvain. "Rubber-ice friction : a multi-scale and multi-physical approach." Thesis, Lyon, 2019. http://www.theses.fr/2019LYSEC017.
Full textDriving on ice is a delicate exercise due to the poor adherence of tire on ice and the use of studded tires is tightly regulated or forbidden in many countries. In this context of road safety improvement under severe climatic conditions, it is necessary to precisely study and investigate the sliding contact between rubber and ice and to determine the different key mechanisms governing the tribological behavior of the rubber-ice contact.The strategy chosen in this work is to investigate the rubber-ice contact at different scales – macrometric (scale of apparent surface contact) and micrometric (scale of group of contact between asperities) – in order to link the physical process of friction and adhesion observed at the macrometric scale to their potential causes induced at subscale.A Surface Force Apparatus (SFA) based system, developed in Kurihara Laboratory, was used to measure rubber-ice interactions under negative temperature condition for thin rubber layer. The morphology of the rubber is strongly influenced by the presence of silica and carbon black within the elastomer matrix, forming bumps of 40 µm in diameter. These bumps have a larger rigidity than that of the surrounding elastomer matrix. They are also responsible for increased dissipation for applied loads lower than 10 mN which may be related to hysteresis phenomenon caused by fillers such as the Payne and Mullins effects and/or interface sliding. The viscoelastic properties of the rubber thin layer measured for the different rubber variants showed consistency with the dynamic mechanical analysis measurement.In parallel, the KŌRI tribometer, developed in LTDS, was used to perform rubber-ice friction experiments the contact under controlled cold environment (temperature and humidity rate). An ice manufacturing unit was also designed to produce a repeatable transparent vertically grown ice disc. The ice transparency makes it possible to investigate the evolution of the rubber-ice contact during friction. The friction behavior was analyzed at the macrometric scale for sliding velocities ranging from µm/s to m/s, temperatures ranging from -15°C to -2.5°C and various rubber mechanical properties. The rubber-ice friction as a function of the sliding velocity presents the characteristic bell-shaped curve observed usually for rubbers. In addition to the sliding velocity, the friction level also depends on the environmental temperature, the sliding history of the ice and the viscoelastic properties of the rubber. Ploughing of the ice surface by rubber asperities was observed during friction measurements. Two main friction phases were highlighted. The first one occurs for ‘low’ sliding velocities where rubber viscoelasticity and ice ploughing may govern the friction within the contact. The second one occurs at higher velocities where melting of the ice surface is expected due to frictional heating within the contact

Full textAlloy 690 (60%Ni, 30%Cr, 10%Fe) is mainly used in primary circuit pipes fornuclear power plants.The aim of this thesis is to form a Cr2O3 layer, using laser surface melting, with the objective ofcreating a chromium-rich oxide layer. In order to optimize the treatment, it was first important todetermine parameters influence on the layer oxide properties then, with the objective of adeeper understanding of mechanisms involved, to address thermo-physical phenomenaoccurring during and after the laser pulse striking the upper surface.A deep parametric study first enabled to find an optimized laser surface treatment whichproduces chromium enrichment of the upper surface and a dense and continuous oxide layer.This treatment has been applied on samples, set in a primary medium simulation loop.Experiments and calculations were carried out to provide understanding of surface chromiumenrichment by laser process. The results were shown to explain chromium enrichment until meltpool solidification occurred on the upper surface, assumingly just before chromium oxideformation. This was also promoted by a high affinity with oxygen and a higher stability of Cr2O3oxide compared with other potential oxide formation
