PhD position on: “Advanced polymeric membranes and dialyzers for developing a miniaturized biohybrid kidney system”

Within the AOT group, we have a vacancy for a PhD student.

Patients with end stage kidney disease (ESKD) need kidney replacement therapy (KRT) to survive, but current solutions (dialysis, kidney transplantation) are insufficient. The majority of ESKD patients is dependent on dialysis which places a heavy burden on their life. Removal of uremic toxins there is inadequate. This project aims to develop a miniaturized extracorporeal device that combines artificial and biohybrid kidney functionalities and would pave the way for developing of an implantable artificial kidney device. For achieving this, new types of artificial membranes and membrane dialyzers would be developed and novel cell cultures protocols there would be investigated. Studies of uremic solutes removal from human blood as well as blood compatibility studies should be performed. The project is part of a larger consortium program, entitled Biohybrid Kidney XB, https://www.health-holland.com/program/BiohybridKidneyXB

As part of the PhD program, you would have the opportunity to receive further education within the Twente Graduate School and within various graduate education programmes in the Netherlands. Furthermore, you are expected to actively contribute to the teaching program, e.g. by supervising BSc and MSc assignments and by acting as teaching assistant in courses taught by AOT staff members.

PhD position on “Electrochemical desalination for the removal of salts and nutrients”

In this project, we aim to develop electrodialysis (ED) and bipolar membrane processes (EDBPM) as separation and on-site chemical production technologies for complex mixtures containing not only monovalent salts but also divalent ions, nutrients, and charged organic molecules. One-side coated ion exchange membranes provide a promising platform in ED and EDBPM processes to tune ion transport, as strong diode behavior of these asymmetric membranes was recently demonstrated. Our goal is to fractionate complex salt mixtures to produce valuable chemicals. Your goal is to develop a toolbox of chemically and mechanically stable membrane coatings suitable for water treatment applications in ED and EDBPM. You will evaluate the performance on complex water streams and identify process limitations by combining experimental results with advanced model development. The project is co-supervised by Jouke Dykstra from Wageningen University and Research.

The project is part of the research consortium BlueVantage. BlueVantage is a large research program with scientific and societal partners that aims to tackle growing water challenges by finding new ways to reuse water safely and sustainably. To that end, BlueVantage explores new treatment technologies to remove persistent organic micropollutants and recover valuable resources from water, thereby ensuring a clean water cycle for economy, ecology and society. The research in BlueVantage is divided over different thematic work packages in which a number of PhDs, their supervisors and societal partners together work on the ambitions of BlueVantage.

EngD Vacancy: Development of Recyclable Mono-Material Food Packaging

The project

This project focuses on creating innovative polyester-based sealable films that enable fully mono-material PET packaging, improving recyclability and reducing waste.

As an EngD, you will work on the validation of new sealing films with improved performance, including lower sealing temperatures, strong seal integrity, and robustness under contamination (e.g., moisture, fats). You will collaborate closely with industrial and academic partners to translate research into practical, scalable solutions for food packaging applications.

PostDoc position on Wafer Bonding Physics for 3D Chip Integration

Wafer-to-wafer bonding is a key enabling technology for future 3D chip integration, where chips are stacked and interconnected to create faster, more compact and more energy-efficient semiconductor devices. However, the detailed mechanisms that determine bonding quality are still not sufficiently understood. In particular, the interplay between surface properties, wafer morphology, and the resulting bonding performance is still largely optimized empirically.

In this postdoctoral project, you will develop and validate experimental methods to study wafer bonding in a quantitative and physics-based way. You will work on wafer bonding measurements and combine these with advanced surface metrology. It is relevant to have experience with analysis techniques such as AFM, WLI, contact-angle, XPS, infrared metrology.

You will work in the XUV Optics group at the University of Twente, embedded in the MESA+ Institute for Nanotechnology. The project offers a combination of hands-on experimental work, data analysis, physical interpretation and close interaction with industrial partners. You will contribute to a scientifically challenging and industrially relevant topic, with the aiming at predictive relations between measurable wafer surface properties and bonding performance for next-generation 3D chip integration.
