PhD Researcher: Separation of rare-earth ions in strong magnetic fields
The rare earths (REEs) are a group of 17 elements in the periodic system, including neodymium (Nd), europium (Eu), terbium (Tb), dysprosium (Dy) and yttrium (Y). These elements have become critical elements (as witnessed by the recent commotion around the Chinese restriction of the export of REEs), because of their essential role inpermanent magnets, lamp phosphors, catalysts and rechargeable batteries. The rare earths occur in nature as mixtures and these mixtures are difficult to separate into the individual elements due to the almost identical chemical properties of the rare earths. For many industrial applications, very pure rare earths are required. This project aims to develop a novel separation method, not based on differences in chemical properties, but rather on differences in magnetic properties. Rare-earth ions in solution will follow different flow paths in a microfluidic device placed in a strong magnetic field, depending on the magnetic character of the ions (diamagnetic, weakly paramagnetic or strongly paramagnetic). Another approach is to use magneto-chromatography for separation of rare earths. In an HPLC setup with a ferromagnetic stationary phase, different rare-earth ions will show different retention times in the column as a function of their magnetic properties.
Master degree with distinction in one of the following fields (or similar): Composites materials, Materials Science, Materials Engineering, Mechanical engineering, Chemical Engineering, etc.
A strong motivation for scientific research is a must.
Candidates having publications and/or conference papers will have an advantage.
A strong interest for multidisciplinary research is required.
Communication skills: ability to work both independently and in a team.
English language proficiency.
The project offers funding for a 4-year program towards a PhD at the KU Leuven within the Department of Materials Engineering, subject to meeting the requirements and deadlines set out by the supervisors and the Arenberg Doctoral School.
KU Leuven offers an exciting multi-disciplinary research environment, a broad gamut of training courses for Ph.D. students, competitive salaries or scholarships and full social and medical insurance.
You can apply for this job no later than November 13, 2016 via the online application tool.
