PhD in `Novel Aerospace Materials` at University Twente

Overview
PhD in Novel Aerospace Materials (Aerospace Engineering Department of Delft University of Technology in close collaboration with the Membrane Technology Group of the University of Twente)

Job description
Currently Delft University is collaborating with the Membrane Technology Group at the University of Twente (UTwente) on a project in which we explore novel, high-performance polymer architectures based on poly(ether-imide) and poly(ether-amide) chemistries as potential materials for high-pressure gas separation applications. In this project we will design and synthesise new monomers and polymers, investigate their thermo-mechanical properties and study their usefulness as films for a variety of gas separation applications (e.g. separation of CO2/CH4 and olefin/paraffin mixtures). You will not only be in charge of polymer synthesis and polymer characterisation but you will also assist with inventorying the membrane properties, which will be done in close collaboration with the UTwente.

PhD in Nature-inspired membranes at University Twente

Overview
Within the Membrane Science & Technology group (www.membrane.nl) we have a vacancy for a Ph.D. position on: `Nature-inspired membranes`
Safe and sufficient water relies on reliable and efficient separation processes. Over the past decades, membrane separations have emerged as the most viable solution to problems such as virus retention, ion retention (desalination) and ion separation (softening). Membranes used in these processes are characterized by an amorphous porosity, broad pore size distribution and low membrane porosity. Even though limited by these morphological constraints, ingenious process schemes on extremely large scale make membrane technology the technology of choice. It is highly desirable to discover new fabrication methods of new membrane materials that overcome those limitations. Filtration with high porosity, thin and isoporous membranes will be the technical solution of choice for particulate matter such as viruses and nano-particles.

PhD Effect of nanoparticles in membrane filtration at University of Twente

Overview
Within the Membrane Science & Technology group (www.membrane.nl) we have a vacancy for a Ph.D. position on: `Effect of nanoparticles in membrane filtration`

Because of the increasing use of nanoparticles, they are ending up more and more in the environment and in drinking water sources. Not much is known on the toxicity of nanoparticles, nor on the effectiveness of membrane filtration in removing them. This project makes and inventory of which nanoparticles are present in natural water, their removal efficiency at drinking and waste water plants, the fouling behavior of feed waters containing nanoparticles and the analysis of the particles.
