Postdoctoral position: atomic scale modelling of metal/metal oxide interfaces

Duration: 18 months

A full-time postdoctoral research position is available in the LAAS-NEO research team at LAAS-CNRS, Toulouse. Within the project “chaire d’attractivité de l’université Fédérale de Toulouse - MUSE”, which aims at developing novel bottom-up engineering towards multifunctional & performance-tailored nano-materials, a two years position is opened for investigating fundamental aspects of the interface formation when processing metal/metal oxide nano-materials.

Ingénieur en Informatique - Statistique et Analyse d'information

Poste à pourvoir pour 12 mois, démarrage Mars 2016, rémunération selon expérience.

Lieu : LAAS – CNRS, Toulouse

Contact : Eric Campo, campo@laas.fr

Sujet : Développement d'une gestion automatique d’un système domotique à domicile

Le LAAS travaille depuis quelques années sur des solutions domotiques innovantes pour renforcer l'autonomie des personnes âgées à leur domicile. Ces solutions repose sur la mise en place d'un réseau de capteurs, essentiellement de présence, et sur l'implémentation d'un logiciel de calcul qui sur la base de la présence permet de construire un modèle des habitudes (habitudes de présence/absence, entrée/sortie...). Un module logiciel permet ensuite de comparer le modèle appris avec la situation courante pour détecter des écarts et assurer une alerte. Le travail proposé s'appuie sur ces concepts et acquis et vise à mettre en place une méthode et outil pour une gestion automatique de l'actionnement des commandes d'activation/désactivation d'un système domotique de surveillance correspondant au souhait de l'occupant. Pour atteindre cet objectif, l’idée est de modéliser les habitudes de vie des occupants de l’habitation (entrée/sortie, présence, ...) et de s’appuyer sur ces modèles, pour assurer la gestion automatique de la commande. Il conviendra de concevoir et prototyper un algorithme embarqué, typiquement dans un PC, reposant sur l'apprentissage de la présence en fonction des horaires et de l'entrée/sortie du logement et le déclenchement d'actions sur la base de règles de décisions. Il s'inscrit dans un projet région en partenariat avec une entreprise régionale.

Compétences requises : Formation de base en informatique. Compétences en développement logiciel, apprentissage et analyse statistique des données, définition et mise en place d'une table et règles de décision, développement d'interfaces utilisateurs.

Qualités attendues : Grande autonomie, curiosité et force de propositions, pragmatisme et capacité à trouver des solutions, bonne communication orale, qualité rédactionnelle.

Engineer or post doctoral position for RF sensors

Job profile 1 : Technological development of RF transducers

Job profile 2 : RF conception and characterization of sensors
 

 

Context

Since the late 1990s, wireless sensor networks emerge as a key technology for numerous applications (domestic, health, environmental, industrial, military, ...) and especially for SHM (Structural Health Monitoring).

In the 2000’s a new class of wireless sensor with electromagnetic transducers appeared, combining RF-MEMS technologies and wireless sensors and using electromagnetic transducers. These transducers are mainly composed of a variable RF impedance or RF resonator connected to an antenna that can be interrogated through backscattered wave analysis. Several concepts are possible to realize a sensor with this kind of device by changing the size, the RF properties of a material constituting the devices and the coupling between different parts of the devices (using displacement of a fluid or mechanical part). The main advantages of these types of wireless chipless passive sensors are : 1) the full energy autonomy (no consumption and no battery), 2) the long range (several ten of meters) interrogation distance compare to other kind of passive sensors (like Surface Acoustic Wave or classical RFID sensors), 3) the high miniaturization (using mm-wave frequency : 24GHz and 79GHz), 4) the compatibility with harsh environments (no active electronic circuits, no battery), 5) the large range of physical and chemical applications.

CNRS-LAAS (MINC team) was among the first laboratories in the world to investigate this new kind of sensors. This laboratory has already validated several original concepts for pressure, temperature, stress and nuclear radiation transducers [1-2] but also Frequency-Modulated Continuous-Wave radar for the wireless localization, identification and reading of these transducers [3-4].

Several funded projects started in 2015 in collaboration with industrial partners and we are looking for 2 research engineers (or post doctoral position) for at least 24 months. The two people will work together and be directly involved on these new projects : the first one more focused on transducers fabrication and the second one on RF transducers conception and characterization.

Nano-material scientist 

Location: LAAS-CNRS, Toulouse, FRANCE

Duration: 18 months

LAAS-CNRS seeks for a self-motivated post-doctoral researcher to take in charge a French-US research project aimed at developing advanced nano-material for energy production applications.

The main goal is to explore how the interface chemistry of nanomaterials affects their thermal properties. This position will involve the synthesis of nanoscale thermite materials (e.g., Al/CuO nanolayers) including potential physico-chemical modifications of their interfaces. The candidate will interact with a larger group effort exploring advanced thin films and nanomaterials for energy production applications, with a particular emphasis on controlling the physical structure and interface chemistry of Al/CuO nanolaminates to develop a better understanding of the fundamental structure-property relationships  of such materials. The collaborative environment requires a candidate who has the ability to work as part of a team with scientists coming from different disciplines and to learn topics outside his area of expertise. The position will involve a combination of nano fabrication (RIE, photolithography, PVD), advanced characterization (HR-TEM, XPS, DRX) as well thermal and electrical analysis to characterize accurately the energetic capabilities.

The candidate will be required to work temporary in clean room facilities and to follow safe work procedures, as well as to handle chemical waste properly and keep a clean, well-organized work environment.

Required Education and Experience:

Must be a recent PhD graduate (within the last three years).

The ideal candidate for this position should have a strong background in the following areas: (1) nanomaterial synthesis and manipulation; (2) physico-chemical modificaions of surfaces (e.g., nanocrystals, nanowires, thin films); and (3) nanoscale characterizing  nanomaterials and their surfaces. Although general expertise in nanotechnologies, chemical engineering and manipulation will be considered.

 

Preferred Qualifications Ph.D. in materials science & engineering, physics, mechanical/electrical engineering or related fields.
