This project is part of our joint efforts with NCCR MARVEL in the computational design of new advanced materials for laser 3D printing applications. At the same time in LAMP, we apply extensive expertise in process design, monitoring, and control as well as state-of-the-art multiphysics modeling and machine learning techniques towards designing Digital Twins for Laser Metal 3D printers, significantly reducing the trial-and-error experimental efforts in simultaneous processmaterial optimization (https://www.empa.ch/web/s204/modeling-simulations). Specifically for this project, we are using Beam 3D printers with our world-unique setup of simultaneous injection of metal powder and reinforcement nanoparticles, which allows for local modification and fine-tuning of process-microstructure-property relations during laser metal deposition. Thus, multiscale multiphysics modeling approach accelerated by deep learning and supported by benchmark and validation experiments is required for successful execution of this project.The research is multidisciplinary and requires close collaboration with experimentalists as well as multiphysics modeling and machine learning experts in the lab. We offer a world-class mentorship, an excellent infrastructure, and broad interdisciplinary surroundings with plenty of possibilities for personal and professional development. Due to a high world interest in additive manufacturing of metals and alloys, the research experience acquired in this program will guarantee exciting future opportunities both in academia and industry, nationally and internationally. The work will be carried out at Empa in Thun, next to Bern, Switzerland, and the resulting PhD degree will be issued by EPF Lausanne.

Environmental pollution by tyre wear and microplastics in general is an issue of growing concern. Tyre wear particles are found in various environmental compartments such as aquatic systems and soils. Their detection far from emission areas indicates that atmospheric transport and deposition are significant processes for the large-scale distribution of tyre wear. In this project, the atmospheric deposition of tyre wear particles is investigated. The project is strongly linked to other studies that focus on wet and dry atmospheric deposition of microplastics (except tyre wear) across Switzerland. Therefore, you will closely collaborate with our partners at Eawag and Agroscope towards a comprehensive and quantitative understanding of microplastics deposition in the environment.

We are looking for a highly motivated candidate with a strong experimental background in materials chemistry, solid state physics or nanoscience who wants to pursue cutting-edge research at a world-class level.

Within this project, you will work on the development of gate-tunable graphene nanoribbon devices and their characterization by Raman spectroscopy, photoelectron spectroscopy and scanning probe microscopy and spectroscopy. To transfer spin-bearing GNRs from their metallic growth substrate to gate-tunable (device) substrates, you will develop ultra-high-vacuum dry-transfer stamping methods. Successful substrate transfer will allow you to control the charge and spin state of GNRs, and to characterize their (opto)electronic and magnetic properties in great detail.

The project: The development of many next-generation technologies requires thin films and coatings, which exhibit more than one functionality. In this research project, we are targeting the development of novel ceramic thin film materials that are capable of this feat. Such materials may combine favorable mechanical properties, such as high hardness or scratch-resistance, with other functionalities. These can range from high transparency and electrical conductivity to their chemical stability or even their piezoelectric response. Applications of such coatings range from simple optical components such as lenses to more complex devices such as MEMS or displays. The materials of interest for this study mainly include ternary and quaternary nitrides and oxynitrides. Simultaneously optimizing multiple functional properties in these materials is a complex challenge with many variables. To accelerate this process you will employ high-throughput combinatorial materials science techniques. The project is part of a larger effort in our laboratory to develop tools and methods to accelerate the development of novel functional thin films. As part of our Accelerated Materials Development team, you will use state-of-the-art physical vapor deposition processes, such as high-power impulse magnetron sputtering (HiPIMS) in combination with automated in-depth materials characterization and data analysis. The goal is to rapidly investigate the synthesis-structure-property relationships in complex synthesis phase spaces.

(a)ll are welcome, regardless of gender, origin etc.Empa's Electron Microscopy Center located in Dübendorf conducts forefront research in the development and application of new electron microscopy techniques in materials science, and has currently two PhD positions available to carry out cutting-edge research in two different projects:The goal of the first project is to explore 4D-STEM (scanning transmission electron microscopy) modalities using an aberration-corrected microscope equipped with an energy filter and a fast, direct electron detector. You will be responsible for innovative, experimental studies aiming at phase and/or strain mapping, differential phase contrast imaging and energy-filtered electron ptychography employing new experimental approaches. As the data sets collected by 4D-STEM are large, an important aspect of the project is data handling and data analysis. You will also coordinate collaborations with internal and external research groups. In addition, simulations can be carried out to complement the experimental part of the project. The second project aims at advancing the understanding of current nanoparticle synthesis routes and at developing alternative pathways for nanoparticles production in ionic liquids, e.g. to effi-ciently produce quantum dots. To study particle formation processes in situ and at the atomic scale, you will perform liquid phase scanning transmission electron microscopy (LP-STEM) experiments on an aberration-corrected microscope. Since the ionic liquids are, besides their outstanding properties as solvents, also useful for reaching high resolution in LP-STEM, you will identify such liquids that are optimal for both aspects. Therefore, you will not only be responsible for exploring new custom-tailored synthesis strategies, but also for further development of the experimental approach. Please express in your cover letter in case you have a preference for one of the two projects.

Your task is to develop and characterize next-generation cathodes for high-temperature sodium-zinc chloride battery cells with molten sodium anode.

Project Background and Job description: Traditional formwork for reinforced concrete structures can account for up to 50% of the total construction cost and 75% of the total construction time and is a major source of wastage in construction as it is often made of timber that is eventually discarded after a few time usage. To overcome the disadvantages of traditional formwork, this cutting-edge project concerns the development of an advanced slab system comprising a geometrically optimized stay-in-place 3D printed concrete formwork and cast-in-place reinforced concrete topping. It is anticipated that the developed system would lead to the construction of lightweight buildings with large material and labor cost savings and may serve as a stepping-stone towards digitization of the construction industry. Within this project, you will develop methods for prestressing 3D printed concrete formwork to improve its load-carrying capacity. Your work will entail the implementation of topology optimization methods on formwork to manufacture slabs with free-form geometries. The project involves finite element modeling, analytical solutions, small- and large-scale experiments for the structural evaluation of the developed slab system. The project aims to culminate in a large-scale pilot application. The doctoral thesis will be pursued in collaboration with research colleagues from Empa and ETH Zurich. The project will start upon mutual agreement, earliest by December 1st, 2022.
