Texto completoNon-destructive testing constitutes a major challenge in research on metallic materials. Indeed, taking into account the mechanical state of the finished component but also throughout the manufacturing process is necessary to best control the design, optimize the performance and service life of the product without destroying components and wasting materials, all in a context of cost reduction and sustainability.A new non-destructive analysis technique using near-field microwave microscopy, based on the variation of electromagnetic fields interacting with materials, has been developed particularly for measuring local micromechanical changes on very small parts. With a lateral resolution of the order of a nanometer, it is entirely suitable for small-scale measurements (nm to mm). It also offers the possibility of obtaining a depth gradient by skin effect depending on the frequency of the signal.This thesis aims to identify the mechanical origin of the microwave signal obtained by this technique on different metals by experimentation (comparison to other analysis techniques) and modeling.In general, the experimental work made it possible to better understand the impact of the mechanical state and to differentiate the effect of a stress (elastic regime) from the effect of a plastic strain on the measured signal. The modeling work has provided a better understanding of the interactions involved

Texto completoVarious disciplines of micro- and nanotechnology requires combinatorial tools for the investigation, manipulation and transport of materials in the submicrometer range. The coupling of multiple sensing and imaging techniques allows for obtaining complementary and often unique datasets of samples under test. By means of an integrated microscopy technique with different modalities, it is possible to gain multiple information about nanoscale samples by recording at the same time. The expansion with nanorobotics and an open-source software framework, leads to a technology approach for semiconductor research and material science. This work shows the potential of such a multimodal technology approach by focusing on a demonstrator setup. It operates under high-vacuum conditions inside the chamber of a Scanning Electron Microscope and serves as a technology platform by fusing various microscopy modalities, techniques and processes. An Atomic Force Microscope based on a compact, optical interferometer performs imaging of surface topography, and a Scanning Microwave Microscope records electromagnetic properties in the microwave frequency domain, both operating inside an SEM. A software framework controls the instrument. The setup allows for observing with SEM, while imaging and characterizing with interacting evanescent microwaves and intermolecular forces simultaneously. In addition, a multimodal test standard is introduced and subsequently confirms the functionality of the demonstrator. Within this context, the work also includes an electrical analysis of micro-scale MOS capacitors, including an approximation for use in the calibration

Texto completoSolvent-Free Microwave Extraction (SFME) is a new extraction process developed at thé Laboratoire de Chimie des Substances Naturelles et des Sciences des Aliments of Université de La Réunion. SFME is a combination of traditional extraction technique and an innovative technology, microwave heating. When we compared SFME and HD oil extraction on aromatic herbs and spices, we found that, herb extraction times from leaves are greatly reduced (up to seven times less) using SFME, spice yields are higher using HD. However, substantially higher amounts of oxygenated compounds, thé most valuable in terms of fragrance, are présent in thé essential oils extracted by SFME when compared with HD. Scanning Electronic Microscope techniques showed that using microwaves contributes to an almost instantaneous release of essential oils from thé glandular hairs and cells. Différence in essential oil composition between ESSAM and HD could be explained by solubility phenomena

Texto completoThermal characterizations at nano-scale remain a challenge since the emergence of nano-structured devices. Having advantages in term of lateral resolution compared to far field techniques, the scanning thermal microscopy has become an essential tool for local materials heat transport characterization. In the frame of the European Quantiheat Project, several laboratories have worked together trying to figure out and to obtain quantitative thermal measurements covering spatial scales from the micrometre to the nanometre.This document contains six chapters with four main parts, in which micro-wire thermocouple based SThM probes have been used to enhance our knowledge in quantitative thermometry at this scale. This kind of probe has been developed and improved for several years. We demonstrate that it is adapted for measuring temperature of active samples as well as thermal conductivity of passive samples.Through the dissertation, the last version of the microscope (hardware, software) and probe design are presented. Attached on a quartz tuning fork, the tip-sample contact force can be quantified. Placed in a vacuum chamber, this system permits a full control of predominant parameters on the measurement such as air pressure and contact force. Thanks to samples provided by Quantiheat partners, measurements in active and passive modes have been performed to demonstrate that quantitative measurements are feasible. By changing ambient conditions from primary vacuum to ambient pressure, the tip-sample heat transfer mechanisms have been analysed in detail to reveal the preponderant role of air and solid-solid contact conductions

Texto completoA titre de comparaison, les huiles essentielles de plantes aromatiques fraîches et d'épices sèches ont été extraites par l'ESSAM et par une technique plus traditionnelle l'HD. Concernant les plantes aromatiques fraîches, les rendements sont identiques à ceux obtenus en HD et les temps d'extraction sont divisés par sept. Pour les épices, les rendements sont meilleurs en HD. La fraction en composés oxygénés, réputée pour être la plus valorisable au niveau olfactif, a une teneur toujours supérieure en utilisant l'ESSAM.
L'observation au Microscope Electronique à Balayage (MEB) des végétaux (feuilles ou graines) soumis à l'ESSAM et à l'HD a mis en évidence la spécificité de l'ESSAM au niveau des mécanismes de libération et d'extraction des molécules aromatiques au sein du végétal. L'effet des micro-ondes a pour conséquence une libération plus rapide de l'huile essentielle contenue dans la plante grâce à l'ouverture quasi instantanée des glandes et poils sécréteurs. L'explication de la différence de composition chimique entre les procédés d'extraction par HD et par ESSAM pourrait être basée principalement sur des phénomènes de solubilité.

Texto completoCorrelative microscopy is the result of the combination of two or more microscopy techniques to provide complementary information on a sample. When using a scanning electron microscope (SEM) and an atomic force microscope (AFM), AFM-in-SEM correlative microscopy not only enables the 3D characterization of samples observed inside a SEM, but also the manipulation of micro- and nanostructures with an extremely high precision. This technique can be applied to various samples in biology, electronics and materials science. Although existing AFM-in-SEM solutions in the current state of the art are powerful, they require expert users; they are not versatile enough to be used for different types of tasks; and they use Cartesian AFM robots that severely limit the dexterity and performance of the imaging system. The aim of this thesis is to study and experiment an original concept of an AFM based on poly- articulated robotics for AFM-in-SEM correlative microscopy. A homemade 6 DoF (3 translations and 3 rotations) robotic AFM system is developed and integrated inside a SEM. The ability to control 3 positions and 3 rotations of a micrometer sized AFM probe while keeping the center of rotation at the close proximity of a micro-structure is very challenging. This is mainly due to the uncertainties inherent to the assembly of micro-robotic systems and clearances in the joints of the robot that are of the same order of magnitude as the required AFM probe positioning accuracy. Robot calibration methods and control theory can however overcome these limitations as demonstrated in the thesis. Control strategies and a user interface are studied to operate the multi DoF correlative imaging system in a versatile and intuitive way for low-level end users while keeping it enough powerful for high-level end users. Several key features that go beyond the state of the art are implemented, including - Vision based control for fast and automated landing of an AFM probe on a micrometer sized sample with robustness with respect to the SEM magnification. The user can select any region of interest (ROI) on a sample by simply performing a mouse click on the SEM screen. Whatever the SEM magnification, the control algorithm ensures a safe landing of the AFM probe on the ROI. The surface of the sample can be as high as several square centimeters and the positioning can be achieved with a micrometric precision. - In-plane and out-of-plane rotation of a sample relatively to the AFM probe while keeping the center of rotation around the tip of the AFM. The center of rotation is defined by the user with a mouse click on the SEM screen. This feature is useful for manipulation and topography tasks, as well as for multi-angle observations of a sample inside a SEM. - Trajectory/speed selection modes. Low speed AFM mode for a detailed topography imaging. Fast AFM mode (4fps) for dynamic observations at the nanoscale. The users also have access to the control parameters. They can be modified to suit their needs. - Mosaic AFM mode to extend the topography scanning area inside a SEM. All these features rely on research works in robotics, mechatronics and control made during the thesis. The latter has the potential to opens the door to a new era of poly-articulated atomic force microscopes used in correlative microscopy

Texto completoAfter classifying the various probes used in near field optics, we present a new polymer probe for field optics microscopy. We describe its fabrication and its major optical characteristics and then present the improvements that can be made to those probes in order to enhance their resolution. In order to use those new probes, we developed a scanning near field optical microscope (SNOM) using a regulation system based on a quartz tuning fork. We present the experimental apparatus concentrating ourselves on the development of the regulation system. We then expose some chosen results obtained with the polymer probes. We thus present two luminescence studies : a study of a nanostructured luminescent sample which allowed us to determine the resolution of the probe used, and a study on the luminescence of optically nanostructured porous silicon. Next we present results obtained on guided optics and optoelectronics samples : a mode study on a vertical cavity surface emitting laser (VCSEL), and a new method for mapping the refractive index inside a guiding structure, and finally we observe modes propagating through an optical waveguide which allowed us to test yet another aspect of the polymer probes. Lastly, we present a study of the coupling between fluorophores and metal nanoparticles
