Dans cette étude, nous allons considérer les propriétés photoélectroniques du dioxyde de titane. TiO2 est un semi-conducteur qui peut absorber un rayonnement ultra-violet pour créer une paire électron-trou. Ces porteurs de charge vont alors migrer à la surface du matériau pour pouvoir réagir avec l’environnement. C’est cette nouvelle réactivité photogénérée qui est exploitée dans le processus de photocatalyse. De nombreux efforts de recherche sont dirigés vers ce composé pour en faire un photocatalyseur efficace pour la dépollution des eaux ou de l’air, tirant parti de son fort pouvoir oxydant sous irradiation UV et de sa stabilité thermique et chimique. Le dioxyde de titane est également abondamment utilisé dans les cellules solaires à colorant.Notre objectif est de synthétiser et d’étudier des nanoparticules d’anatase modèle afin de corréler les propriétés de surface aux résultats obtenus en photocatalyse et en photovoltaïque. Une telle approche devrait permettre une meilleure compréhension de ces processus photoélectroniques et de prétendre à une approche plus prédictive de conception de matériaux plus performants. Des nanoparticules d’anatase présentant des morphologies bien définies ont été synthétisées pour disposer d’un large éventail d’objets modèles de réactivité différente. Leur caractérisation de surface a été appréhendée en combinant des outils expérimentaux (spectroscopies in situ, dynamique des porteurs de charge, …) et des outils de chimie théorique pour apporter le plus d’éléments de compréhension possible aux systèmes étudiés. Cette étude à la fois théorique et expérimentale s’est appuyée sur l’expertise des deux laboratoires rattachés à l’école doctorale européenne IDS-FunMat (financement UPMC avec mission d’enseignement) : le Laboratoire de Chimie de la Matière Condensée de Paris (LCMCP) et le laboratoire de Chimie Physique Théorique (CPT) de l’Université de Liège. Ainsi, grâce aux connaissances avancées en synthèse et caractérisations de nanoparticules du LCMCP, en modélisation DFT de clusters du CPT et enfin à de nombreuses collaborations universitaires, nous avons pu apporter un nouvel éclairage à la compréhension des propriétés de surface dont les publications et résultats essentiels sont développés dans les cinq chapitres de ce manuscrit.

The 1st September 1995, the belgian Federal Ministry of Agriculture set up a compulsory control of the sprayers used. All the devices, except for some ofthem, are subjected to a compulsory periodic checking. The practical organsization of the control as well as the test procedure are a bit different from the ones of other European countries. They have been chosen on the basis of educational criteria rather than repressive ones. After 20 months of control, the result is encouraging. More than 13 000 sprayers have already been controlled. Less than 5 % of the devices are rejected after a first control. The condition of working sprayers has been improved. At last, this action has made the controlled owner conscious of the problems related to the spreading og agrochemicals. [less ▲]

In 1964 – 1965, four long term trials were established in Tunisia to compare several origins of Aleppo pine (Pinus halepensis Mill.). Nearest neighbour models were used to control soil’s heterogeneity and to reduce experimental error unitil to 79 %. After adjustment of data, statistical methods are applied to choice origins for a reforestation program. [less ▲]

Depression is a pathology frequently observed in general medicine (10%). Treatment of depression makes great use of drugs from different pharmacological classes. The optimal posology is difficult to establish, and clinicians prefer to avoid side effects by prescribing low regimen. This study is related to an evaluation of seric antidepressant concentrations in comparison with the daily doses in a large psychiatric population. Side effects of drugs are appreciated by enzymatic determinations. [less ▲]

An instrument based on the "electronic nose" concept was developed with the aim of controlling an odour abatement technique, as the spraying of masking or neutralising agent, on a landfill area in Belgium. Models of odour recognition and of odour level prediction were developed and successfully validated in the field. Additionally to e-nose response, the influence of meteorological data was particularly studied. The project was conducted on a real size facility and in close collaboration with the manager of the facility. [less ▲]

The morphology of abrupt bursts of magnetic flux into superconducting films with engineered periodic pinning centers (antidots) has been investigated. Guided flux avalanches of thermomagnetic origin develop a tree-like structure, with the main trunk perpendicular to the borders of the sample, while secondary branches follow well-defi ned directions determined by the geometrical details of the underlying periodic pinning landscape. Strikingly, we demonstrate that in a superconductor with relatively weak random pinning, the morphology of such flux avalanches can be fully controlled by proper combinations of lattice symmetry and antidot geometry. Moreover, the resulting flux patterns can be reproduced, to the fi nest details, by simulations based on a phenomenological thermomagnetic model. In turn, this model can be used to predict such complex structures and to estimate physical variables of more di fficult experimental access, such as the local values of temperature and electric fi eld.

Abstract. Objective. This work aims at flexible and practical pulse parameter control in transcranial magnetic stimulation (TMS), which is currently very limited in commercial devices. Approach. We present a third generation controllable pulse parameter device (cTMS3) that uses a novel circuit topology with two energy-storage capacitors. It incorporates several implementation and functionality advantages over conventional TMS devices and other devices with advanced pulse shape control. cTMS3 generates lower internal voltage differences and is implemented with transistors with lower voltage rating than prior cTMS devices. Main results. cTMS3 provides more flexible pulse shaping since the circuit topology allows four coil-voltage levels during a pulse, including approximately zero voltage. The nearzero coil voltage enables snubbing of the ringing at the end of the pulse without the need for a separate active snubber circuit. cTMS3 can generate powerful rapid pulse sequences (< 10 ms inter pulse interval) by increasing the width of each subsequent pulse and utilizing the large capacitor energy storage, allowing the implementation of paradigms such as paired-pulse and quadripulse TMS with a single pulse generation circuit. cTMS3 can also generate theta (50 Hz) burst stimulation with predominantly unidirectional electric field pulses. The cTMS3 device functionality and output strength are illustrated with electrical output measurements as well as a study of the effect of pulse width and polarity on the active motor threshold in 10 healthy volunteers. Significance. The cTMS3 features could extend the utility of TMS as a research, diagnostic, and therapeutic tool. [less ▲]
