LIST website - Job offers https://www.list.lu/ Latest job offers from Luxembourg Institute of Science and Technology website. Master Student Internship in High-performance polymer filled with electro-conductive nanoparticles: influence of nanofillers structure on electrical resistivity Current space missions require the use of light materials having a high resistance to space environments as electrical charging, heat cycling, UV, vacuum, etc. To this end, polymer composite are widely used but to date, their long term stability is far from being satisfactory. One way to dissipate charging effect is to disperse electrically-conductive nanoparticles within polymer matrix. We propose to develop and characterize such a material whose originality will rely on the nanoparticle structure that can be tuned. The training will be organized into three parts: (i) State of the art and testing plan definition, (ii) Nanoparticle synthesis and characterization, and (iii) Nanocomposite processing and electrical/structural characterization. Nanoparticle synthesis and nanocomposite processing will be done by the trainee, as well as routine characterizations, while advanced characterizations will be done by specialists. At the end of each part, a report will have to be delivered and a final presentation will have to be prepared. ]]> https://www.list.lu/jobs/interns/internship-offer/?tx_listjob_listjobdisplay%5BlistJob%5D=3833&cHash=fe409d0a5533dff73744418c147e515a Master Student Internship in Identification and handling of hazardous substances in construction (material) Awareness on the presence of hazardous substances in construction materials and the desire to use "healthier" construction materials is increasing, but available information is still limited to make an informed choice. The trainee would assess available information on hazardous substances in construction materials, based on a review of the current legislative framework in the EU, literature and available databases. Strategies to substitute hazardous substances with less hazardous alternatives and/or identification of decontamination and recycling technologies could be determined for a selection of substances in construction materials. The targeted outcome is an improved information basis to support the selection of construction materials with less human health and environmental risks. The trainee will learn about the application of EU chemical and products legislations to a group of products, namely construction products, and will gain a better understanding of health and environmental risks of these products.      ]]> https://www.list.lu/jobs/interns/internship-offer/?tx_listjob_listjobdisplay%5BlistJob%5D=3831&cHash=0992e8accab7f7517cd4997afe35b5be Master Student Internship in parametric modelling applied to office building The purpose of the internship is to contribute to developing a parametric model of an existing office building enabling the adaptation of the spaces according to the changes of an organization through time (new comings and modification of the services), while maintaining the adjacency between the spaces when required.  
The trainee will be working on a configuration of a plug-in or a 3D model based on parametric modelling. The main function of this plug-in is to help the reorganisation of spaces accordingly. The internship will specifically target to: (1) the parameters affecting the office layout, and (2) the relation between the different parameters and building elements.
Integrated into the project team, the trainee will be responsible of:
  • Updating scientific and technological state-of-the-art in the parametric modelling in general
  • Defining together with the team the specifications for a demonstrator prototype, targeting the design of the building office layout adapted to the requirements related to spaces and functions
  • Implementing, deploying and testing the prototype in LIST

Undifferentiated cells have been habituated to cellulose biosynthesis inhibitors by growing them on stepwise increasing concentrations of dichlobenil and isoxaben and they will be treated with 200 mM mannitol, which mimicks drought stress. Cells will be collected and would require an in-depth analysis.
The tasks will consist in the extraction of proteins for their analysis by LC-MSMS and/or 2D DIGE. A metabolomics study will also be conducted for these samples. Furthermore, results will be compiled and analysed by bioinformatics tools. Data will be used for further publications (poster or manuscripts).     ]]> https://www.list.lu/jobs/interns/internship-offer/?tx_listjob_listjobdisplay%5BlistJob%5D=3826&cHash=6626eca9e24364a2171f760e9f1c7405 Master Student Internship in Surface treatment and physico-chemistry LaserSTAMP project description: Combining the very specific material properties of polymers and metals enables a variety of products with tailored properties. As metals and polymers are well known and understood, the combination of both cannot be used due to missing joining knowledge.
The objective of project LaserSTAMP is to introduce a laser based thermal welding process for hybrid polymer-metal structures. Whereas successful research projects on thermal joining of polymer-metal structures have shown the general feasibility of selected material combinations, the comprehensive scientific process understanding and explanation of the joining phenomena is still missing.
The main goal of the project is to understand the physicochemical bonding phenomena. We will investigate the impact of different surface treatments. As energy source, a brilliant laser beam source will be used.
Recent results from our team emphasized the prominence of aluminum (Al) surface modification to promote the adhesion between modified Al and polyamide 6.6 (PA) after laser welding. However, further investigations are needed in order to provide relevant results when the surface chemistry of both adherents is significantly modified.
Therefore, the objective of this internship is focused on the development of thin coating deposition methods (mainly by dipping/spraying techniques) on Al. These coatings aim at promoting the adhesion between Al and PA. The surface chemistry of the coating will be chosen to develop a good adhesion with PA. Coating characterization techniques will be useful to understand the results in terms of deposition parameters and adhesion promotion, and in order to improve the adhesion promotion effect.
Depending on the progress of this study dedicated to coating deposition on Al, the same kind of investigations can be envisioned by coating the PA side for further adhesion promotion with Al. ]]> https://www.list.lu/jobs/interns/internship-offer/?tx_listjob_listjobdisplay%5BlistJob%5D=3821&cHash=f746c2225170d29fe1b2f917dbcb5277 Master Student Internship in Development of a curriculum for learning to program with Kniwwelino Your mission is to develop pedagogical instructions in paper or web-based form, supporting children to learn programming and electronics.

She/he will integrated in the research group, working with the Group Leader and the Engineer responsible of the mobile app. The internship will take place at the premises of LIST in the “Maison de l’Innovation” situated in Esch/Alzette, Luxembourg.
In the context of a European research project (www.crosscult.eu), we have developed a mobile app and web applications for the design, discovery and sharing of geo-localised points of interests (POI). The mobile app is designed like a game where users can walk from a POI to another, discovering stories about places, buildings or parts of their environment, can like or comment POIs and even create their own POIs that they can share with other users. The goal of the traineeship will be to enhance the mobile app ecosystem, so that they support 1) automated personalization features, including for example user profiling and recommendation of POIs to see or stories/comments to read; and 2) Augmented Reality features, to transform the user experience. This will be realized following an experimental approach where developed features have to be systematically evaluated in real settings with users. The user studies will be used to assess the usefulness of the new features and their impact on the user experience.
The project involves: 1) programming the new features with state of the art solutions (a small state of the art survey might be asked); 2) testing with users and leading questionnaire-based interviews to gather user feedback on user experience; and 3) analyzing the user survey to conclude on features’ usefulness and impact on user experience. ]]> https://www.list.lu/jobs/interns/internship-offer/?tx_listjob_listjobdisplay%5BlistJob%5D=3806&cHash=b86fdc6c8512c00312dfbf6975412459 Master Student Internship: Développement d'un prototype logiciel d'aide à la planification dans le domaine de la construction (M/F)
  • la maquette numérique du bâtiment ;
  • le chantier connecté ;
  • le bâtiment intelligent.
    • Dans le cadre de l'axe relatif au chantier connecté, les travaux de recherche menés par le groupe DBEM visent à améliorer la gestion opérationnelle de chantier et portent sur différents aspects :
    • la collaboration et le management visuel pour planifier la phase de construction ;
    • la maquette numérique du bâtiment pour supporter la décision lors de la phase de construction ;
    • l’Internet of Things (IoT) pour monitorer le chantier et objectiver les décisions lors de la phase de construction.

    La coordination et le pilotage de la phase de réalisation des projets de construction est traditionnellement une source importante de difficultés. La diversité des intervenants, la multiplicité des techniques employées et la complexité grandissante des ouvrages, rendent difficile la collaboration entre les équipes en charge de leur réalisation. Initialement développé par l’industrie automobile pour améliorer la performance de ses chaines de production, le lean construction, ou « construction sans gaspillage » est une philosophie de travail dont l’objectif est de créer de la valeur pour les clients de manière durable, via l’amélioration de l’ensemble des processus d’un projet de construction.
    Parmi les méthodes employées le « Last Planner® System » ou LPS est une approche visant à fiabiliser le délai de réalisation à travers un travail systématique de planification grâce et pour les différents acteurs d’un projet. Conçue pour être collaborative, elle exige l’implication de tous les acteurs du chantier et applique les préceptes du Visual Management pour assurer la communication entre les corps de métier.  Depuis plusieurs années et au travers de cas d’étude concrets, le LIST déploie et teste cette méthode basée sur l’utilisation de post-it permettant d’identifier et de partager les tâches à réaliser, en les agençant de manière structurée sur des panneaux physiques. Conçus et positionnés de manière collaborative par l’ensemble des parties prenantes au projet, ils permettent de préciser leur granularité, d’identifier leurs pré-requis (organisationnels, humains, matériel, etc.), et de produire différents niveaux de planification pour assurer la gestion opérationnelle du chantier. Se basant sur un ensemble de scénarios de planification déployés sur un logiciel de Visual Management propriétaire gérant la couche graphique de manipulation des post-it, le travail consistera à concevoir et développer en javascript un proof of concept graphiquement similaire, mais offrant des possibilités algorithmiques supplémentaires, vecteurs d’innovation et d’améliorations fonctionnelles. A visée démonstrative, cette application permettra aux spécialistes métiers d’identifier et de tester les nouvelles fonctionnalités (traitement de données, règles métier) utiles au déroulement de la méthode, en vue de les intégrer au cahier des charges de la future release. Au sein du groupe de Recherche DBEM (Digital Build Environment Management) et en partie rattaché à l’équipe chargée des réalisations IT du Département, le stagiaire mettra à profit ses connaissances en développement full-stack intégrant plusieurs technologies. Outre l’utilisation des derniers frameworks javascript, il pourra également approfondir ses connaissances en conception d’architectures logicielles et bénéficier d’une première expérience de développement en lien direct avec des professionnels du secteur de la construction. ]]>     https://www.list.lu/jobs/interns/internship-offer/?tx_listjob_listjobdisplay%5BlistJob%5D=3804&cHash=f4f8543d7b9581a8c22ef80f61a1d0a6     Master Student Internship in Investigating the influence of land-atmosphere coupling and stomatal control on water vapour and trace gas fluxes (M/F) The exchange of water vapour and trace gases between biosphere and atmosphere occurs through turbulent transport (mixing) of these air constituents towards and away from the surface. Plants exert a major control on this exchange as the uptake of CO2 and the simultaneous release of water vapour through plant stomata (transpiration) is accompanied by uptake or emission of atmospheric trace gases, such as e.g. ozone. Evaporative water losses and the simultaneous exchange of trace gases with ecosystems are strongly determined by vegetation through the dynamic control of the surface (stomata) conductance. Meteorological conditions such as rainfall, solar radiation and vapour pressure deficit strongly influence this conductance by modulating soil moisture and atmospheric demand for water vapour. This internship aims to explore the interaction of evapotranspiration and trace gas fluxes based on existing data sets (Eddy Covariance) using modelling approaches. In this context, the influence of land-atmosphere coupling and stomatal control on the interaction between evapotranspiration and trace gas fluxes (preferably ozone deposition) will be investigated. ]]> https://www.list.lu/jobs/interns/internship-offer/?tx_listjob_listjobdisplay%5BlistJob%5D=3799&cHash=d996ee28e3504626479257fb81a034d0 Master Student Internship in Inkjet Printing of Transparent Piezoelectrics (M/F) Trainee will use the existing knowledge on inkjet printing of piezoelectrics on silicon and perform it on alternative substrates. The work will consist of the following steps:
    • synthesis of the inks (based on chemical solution deposition);
    • inkjet printing (jetting of the inks, control of interaction of the inks with the substrate, crystallization at high temperatures);
    • microstructural and electromechanical characterization of the structures.

The activities include the preparation of various datasets for efficient processing and analysis by cleaning and integrating them into a unified platform. During this internship, the selected student will have to:
    • Analyse spatial and temporal distributions of end-users’ needs in terms of waste collection. This will serve as a valuable input to schedule optimised collection paths.
    • Investigate and implement data anonymisation techniques and personal data protection issues.
    • Design a visualisation tool enabling a deeper data analysis (e.g. detection of periodic behaviours per customer and more generally customer characterisation/fingerprint based on temporal distribution of waste collection needs).
    • Perform initial deployment and test of ultrasonic sensors that will be used to monitor in real-time the fill-level of smart bins.

Composite with desired properties can be achieved simply by controlling the distribution, shape and orientation of the heterogeneities within the matrix. LIST researchers have created a toolbox combining imaging tools and techniques with numerical mechanics methods to virtually create composite materials with tailored physical and mechanical properties. The programming was done in Python and a rudimentary graphical interface was realized with the module Tkinter. The Mahotas and Mayavi libraries are used for image analysis and visualization. The student will develop a user-friendly graphical interface. Visualization of 3D objects will therefore be an important aspect of the work. Project plan:
    • Task1: Understand the existing structural scheme of the python code towards possible reorganization of the code structure (1 month)
    • Task2: Develop a user-friendly graphical interface (4 months)
    • Task3: Final report

They can be used in a variety of optoelectronic applications such as solar cells, touch panels and organic light emitting diodes. Ag NWs are cheaper to fabricate than ITO and can be fast deposited as networks with spray method. In order to understand the effect of spray parameters on Ag NWs networks conductivity and transparency, the NWs density has to be determined thanks to scanning electron microscopy image analysis

    The goal of this internship will be to investigate computer and mathematical methods to determined Ag NWs density with aspect ratio (AR) above 1000 (AR=L/D where L is NWs length and D is NWs diameter), where a challenge occurs when considering interconnected NWs. The trainee will start by analysing existing plugins for the Image J image processing software, as well as modifying existing plugins and programming automated processing routines. He/she will also investigate mathematical approaches based on the NWs geometry in order to simplify the programming challenges.
