PhD project: Development of a continuous mode (micro-)separation device

Duration: 4y

Start: 1/6/19 (Brussels/B and Enschede/NL)

The 21st century is developing such that society relies ever and ever more on (bio-)chemical measurements of fluids and matrices. By shaping microfabricated silicon-based pillar arrays, our group has during the past years drastically changed the separation capabilities and perspectives of analytical separation devices, allowing for an analytical batch type of separation of thousands of component types in single run. Next to analytical separations, there is a stringent need to perform continuous separations of molecules of interest, e.g. as a purification step of a medicine of interest so that it can be safely administered to the patient. In a reaction engineering context, it is also interesting to immediately remove products from a reagent stream during a reaction to minimize energy consumption and positively influence chemical conversion. Unfortunately, there is no continuous analogue of chromatography, capable of separating several types of small molecules in continuous mode. In the present project, such a continuous HPLC mode device is developed.      

The research will take place predominantly at the Free University of Brussels (VUB, promotor: Prof. Wim De Malsche), in close interaction (with min. 25 % research stays) with the Mesa+ Institute for Nanotechnology (UTwente) in Enschede, The Netherlands (promotor: Prof. Han Gardeniers).

Job description

Your work will have both an experimental and a modeling character. You will design and fabricate silicon and glass separation devices. You will develop electrochemical anodization protocols to increase the specific surface of the devices on innovative configurations. You will study devices that have been fabricated in a state-of-the art cleanroom on setups that you will develop. You will also be involved in the demonstration of proof-of-concepts of improved efficiencies of miniaturized reactors.  This dynamic atmosphere of the group and consortium will enable you to make important contributions on both the fundamental physics side as on the application side. You will interact with and present your results to a network of industrial and academic partners involved in other aspects of the project.

Your profile

You have a Master’s degree in physics, electrical, biomedical or chemical engineering and you are interested in microfluidics, microfabrication and material engineering, separations and reactors. You are creative, are comfortable with both experimental and theoretical work, can function independently and are willing to travel frequently between The Netherlands and Belgium. We expect the candidate to have an excellent command of the English language as well as professional communication and presentation skills. You will obtain a double PhD degree (VUB and Twente University).

Interested? Contact Prof. Wim De Malsche (wim.de.malsche@vub.be)

PhD researcher in Carbon Capture

The adsorption team of the Department of Chemical Engineering (Prof. J. Denayer) at the Vrije Universiteit Brussel aims at the development of better and sustainable separation processes. In the present project, new methods for CO2 capture are studied. 2 PhD positions are available. This research fits in a larger project, aiming at the catalytic reduction of CO2 to Solar Fuels and Chemicals. Research activities in these PhD projects include the formulation of new materials (3D-printing); characterization of the adsorption properties of the materials via a range of experimental methods (gravimetry, volumetry, calorimetry, porosimetry,…) available in the research group; modeling of the adsorptive separation process.

Admission requirements

Preferably, the candidate owns a degree in Chemical Engineering, Bio-engineering or (Physical) Chemistry. Experience is a plus.

Interested?

The candidates should contact Prof. Joeri Denayer at joeri.denayer@vub.be. Please send a complete Curriculum Vitae, with a recent photograph, and the names of two leading scientists who are ready to support your application and recommend you as an active, creative and autonomous researcher, ready to work in a team. For more information, please check the vacancy description: PhD researcher in Carbon Capture.

Postdoctoral Researcher in Pressure Swing Adsorption

Project description:

The adsorption team of the Department of Chemical Engineering (Prof. J. Denayer) at the Vrije Universiteit Brussel (http://vubchemicalengineering.be) aims at the development of better and sustainable separation processes. In the present project, an industrial Pressure Swing Adsorption (PSA) process is optimized. A fully equipped 2-bed pilot PSA unit is available in the research unit, allowing to obtain very accurate data for the cyclic separation process. In this project, pilot plant tests will be combined with detailed modeling of the PSA process to achieve an improvement of process performance in terms of power consumption, productivity etc. Besides, a full characterization of the adsorption properties of the materials used in this separation will be carried out via a range of experimental methods (gravimetry, volumetry, calorimetry, porosimetry,…) available in the research group.

Requirements:

Preferably, the candidate owns a PhD Degree in Chemical Engineering and a doctor’s degree in adsorption. Experience in modeling of Pressure Swing Adsorption and/or Temperature Swing Adsorption and/or Simulated Moving Bed is a plus.

Start date:

January 2019.

All details can be found in the following document: Postdoctoral Researcher in Pressure Swing Adsorption.
