Are you ready for a green CO2 utilisation challenge? Join our TU Delft & TNO project team as postdoc for electrochemical carboxylation – E-CARB!
Although there is significant progress related to electrochemical utilisation of CO2, the field of carboxylation has been lacking. E-CARB is developing a showcase for a novel electrochemical utilization route of CO2, renewable electricity and circular bio-feedstock for the production of adipic acid, a precursor of nylon 6,6 polymer. E-CARB gathers a consortium of academic experts and companies along the nylon 6,6 polymer value chain from Germany and the Netherlands. You will work together with a team of leading experts from TNO, TU Delft and Frauenhofer on the development of an electrochemical carboxylation route using CO2 and butadiene as starting materials. As a postdoc, you will be aiming to achieve the exciting goal of experimental proof of concept.
You excel at conducting advanced electro-chemical research and being at the forefront of experimental work in your field. Working with your colleagues and our partners, you leverage your communication skills to drive progress. And while growing your own skills and knowledge, you are committed to coaching and interacting with students. You need to have:
- A PhD degree in Mechanical engineering, Chemical engineering, Chemistry, Applied physics, or related field is required.
- Excellent familiarity with (electro-)chemical experimental work is considered an advantage.
- A critical and inquisitive attitude with regard to results is expected, which translates into formulating new research questions.
- Ability to function both in a team and independently.
- Good communication skills. Fluent in English, both spoken and written.
Photosynthetic microalgae hold promise for the sustainable production of high-value products, bioplastics, biofuels and future engineering living materials. Flowing suspensions of living microalgae cells form a living fluid, which physiologically respond to the environment and to the flow conditions. Fundamental knowledge of the flow dynamics of living suspensions of microalgae is now crucial to develop new flow technologies for bioreactors.
Several PhD positions are available in the project “Flow4Algae”. The goal of this experimental project is to understand the multiscale fluid dynamics of living microalgae suspensions. We are particularly interested in the interplay between flow conditions, cell physiology and cell growth. Each different project will focus on flow conditions ranging from linear shear flows in microfluidics to weak turbulence and will characterize cell growth and distribution in the fluid medium and biofilm growth on surfaces. In this project, you will design new multi-scale experiments and analytical tools for the different flow regimes. These studies will be conducted in BioFluids Laboratory in TU Delft and will use the infrastructure in the laboratory including advanced flow diagnostics (Particle Image Velocimetry, Particle Tracking Velocimetry and Laser Induced Fluorescence), microscopy (3D tracking multi-view microscopy and Fluorescence), rheology tools, microfluidics and existing flow dynamics set ups.
As a PhD, you will be part of a vibrant team of researchers working on the project Flow4Algae, which is housed in the Biofluids laboratory, Fluid Dynamics and Multiphase Systems groups, with diverse backgrounds and expertise. The group is part of the Process & Energy Department, which thrives to conduct world-class research & education focusing on process & energy technologies for sustainable development.
The research is conducted from a deep understanding of the underlying physics and is oriented towards industrial applications and societal needs. Read more.
Are you interested in survivable DC systems for ships and their integration into the ship power propulsion and energy system?
Energy transition, smart manning, and survivability are three of the main challenges of the Navy and the rest of the maritime sector. The NWO project "Survivable DC Systems for Ships" investigates DC system technology that enables integration of energy from renewable sources, and makes it possible to continue operation after failures from wear, calamities such as fires and floods, or missile impact, by being fault tolerant. This project aims to answer the following research questions. First, how to design meshed DC system architectures, components, and protection for vessels in such a way that survivability is maximized? Secondly, how can reliability of the DC system and its components be modelled in such a way that performance can be guaranteed? Thirdly, how to design and control fault tolerant decentralized DC energy systems, and how to integrate them into the ship design? Fourthly, is it viable to replace a part of the DC system conductors by superconductors; what are the benefits of these superconductors and in which parts of the power system should they be applied? TUDelft, TUEindhoven and UTwente are collaborating in this project.
This vacancy focusses on the third research question: how to design and control a decentralized energy system both in normal operation and in the case of extreme events? How can energy sources and loads be distributed over the vessel to ensure safety, reliability, availability, and efficiency? And what are the implications of this DC system architecture for the ship design? Can we get rid of switchboards? Extreme events include electromagnetic guns or laser weapons requiring extremely high power for a very short time and consequences of missile impacts, such of compartment flooding or fire.
The candidate will be working in the Marine Engineering group of the Ship Design, Production and Operation section at the Maritime and Transport Technology department of Delft University of Technolgoy. In addition, he/she will be working closely with other researchers working within other projects at TUDelft dealing with energy transition in the maritime sector. Furthermore, this research will be carried out in close collaboration with a user committee with representatives from the Navy, industrial partners and other research institutes. Read more.
Model the next generation of alkaline water electrolyzers.
Alkaline water electrolyzers, for green hydrogen production, have been used at a large scale for about a century. Presently, a large scale-up in the number and size of industrial electrolyzers and electrolyzer plants is taking place, using modern materials and construction techniques. Their larger size and higher current densities require a partial re-design in which the numerical simulations you will perform can be of great assistance.
Removing the large amounts of gas produced in stacks consisting of many cells, while avoiding large shunt currents, requires you to careful consider the geometry and dimensions of the manifold and channels. Inside each cell, the membrane-electrode and electrode-bipolar plate distances, and the elastic element properties influence the gas distribution, pressure drop, and energy efficiency in a yet unknown way.
In this project, in collaboration with McPhy, you will use multiphysics multiphase simulations to answer some of the design questions associated with the scale-up of future water electrolyzers. Read more.
