The Institute of Physics (IoP) has a PhD position 'Consolidation of damaged porous media'.
Porous media such as buildings and artworks can be severely damaged due to e.g., frost or salt crystallization. When the porous material loses its mechanical integrity, solutions have to be found to preserve it by consolidating the material. We propose a combined experimental and computational PhD position at the interface between physics, chemistry and mechanical engineering. We are seeking an excellent, highly motivated PhD student to carry out the interdisciplinary research to unravel the routes and underlying mechanisms for the consolidation of porous media. The most promising route for consolidation of stone artworks is to fill the pore space of stones by polymer solutions and induce a sol-gel transition through evaporation of the solvent. While the kinematics of transport and drying of Newtonian fluids in porous media has been widely studied by both experimental and theoretical approaches, the case of non-Newtonian fluids remains largely unexplored. The student will employ a coupled experimental-computational approach to study the drying kinematics of polymer solutions in porous media undergoing a sol-gel transition upon evaporation of the solvent. The macro-mechanical reinforcement of the porous medium driven by the sol-gel transition will be investigated experimentally by tensile tests and numerically by finite element micro-mechanical simulations. Undertaking such a combined and multiscale approach, we will be uniquely positioned to provide a coherent and comprehensive picture of reinforcement of such materials.
What are you going to do?
During your PhD project, you are expected to undertake a dual experimental and computational approach to boost our understanding of the underlying mechanisms consolidation of porous media. You will:
Fixed-term contract: 18 months.
A temporary contract for 38 hours per week, preferably starting as soon as possible for the duration of 4 years (initial appointment will be for a period of 18 months and after satisfactory evaluation it can be extended for a total duration of 4 years) and should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.
The salary, depending on relevant experience before the beginning of the employment contract, will be €2,325 to €2,972 (scale P) gross per month, based on full-time employment (38 hours a week). These amounts are exclusive 8 % holiday allowance and 8.3 end-of-year bonus. A favorable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Dutch Universities is applicable.
Are you curious about our extensive package of secondary employment benefits like our excellent opportunities for study and development? Then find out more about working at the Faculty of Science.
With over 5,000 employees, 30,000 students and a budget of more than 600 million euros, the University of Amsterdam (UvA) is an intellectual hub within the Netherlands. Teaching and research at the UvA are conducted within seven faculties: Humanities, Social and Behavioural Sciences, Economics and Business, Law, Science, Medicine and Dentistry. Housed on four city campuses in or near the heart of Amsterdam, where disciplines come together and interact, the faculties have close links with thousands of researchers and hundreds of institutions at home and abroad.
The UvA’s students and employees are independent thinkers, competent rebels who dare to question dogmas and aren’t satisfied with easy answers and standard solutions. To work at the UvA is to work in an independent, creative, innovative and international climate characterised by an open atmosphere and a genuine engagement with the city of Amsterdam and society.
The Faculty of Science has a student body of around 6,500, as well as 1,600 members of staff working in education, research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works, be it elementary particles, the birth of the universe or the functioning of the brain.
You will be based at the Institute of Physics (IoP). The Institute of Physics, one of the large research institutes of the faculty of Science, combines the Van der Waals-Zeeman Institute (WZI), the Institute of Theoretical Physics (ITFA) and the Institute for High Energy Physics (IHEF). You will also become a member of the interdisciplinary Computational Soft Matter Laboratory interconnecting the Institute of Physics, Informatics Institute and Van’t Hoff Institute for Molecular Sciences benefiting strongly form intensive exchange with its other members.
