PhD position - Frictional Colloids

University of Twente (UT)
In the Physics of Complex Fluids group at the University of Twente (part of the MESA+ Institute), research is aimed at
understanding various behaviors of multicomponent fluids near interfaces. One line of research addresses the behavior
of colloidal suspensions under confinement and in flow.
The vacant project in the PCF group focuses on the influence of particle surface roughness on the rheology
of concentrated suspensions, where it is expected that friction plays a central role, leading to a spectacular shear
thickening. This behavior has been attributed to a transition from a ’lubricated’ to a ’frictionated’ particle contact,
above a critical shear rate. This proposed underlying phenomenon will also be studied at the particle level, using
Confocal and Atomic Force Microscopies. In collaboration with the Multi-Scale Mechanics group (Prof. Luding), also
simulations on particles in flow (including their friction and rolling resistance) will be performed by the candidate.
For this ambitious and multidisciplinary project we are looking for a skilled experimentalist (MSc degree) with a background
in physical chemistry or fluid physics. Experience with (the rheology of) colloidal suspensions, and affinity with computer
simulations are considered very advantageous. You are highly motivated and driven to develop into an excellent young researcher
in a competitive field. Collaborations with colleagues within the PCF and MSM groups, the MESA+ institute as well as outside
form an integral part of the work.
We offer a very challenging position in an inspiring multidisciplinary and international environment. As a PhD candidate you
will be offered a full-time (38 hours/week) position for four years, after which you should have completed your PhD thesis.
After 6-9 months into the first contract year admission to years 2-4 is decided based on a qualifier exam. In accordance with
the Collective Labour Agreement for Dutch Universities, the gross monthly salary for a PhD increases from € 2.191,-- in the
first year to € 2.801,-- gross per month in the final year, plus a holiday allowance (8%), an end-year bonus (8,3% of the
annual salary) and a number of additional benefits. The University of Twente provides excellent campus facilities, and
actively supports professional and personal development.
The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and
research that matter. New technology which drives change, innovation and progress in society. The University of Twente is the
only campus university in the Netherlands; divided over five faculties we provide more than fifty educational programmes. The
University of Twente has a strong focus on personal development and talented researchers are given scope for carrying out pioneering research.
Within the TNW Faculty (Faculty of Science & Technology) of the University of Twente some 700 staff members and 2000
students are involved in training and research on the interface of chemical technology, applied physics and biomedical technology.
Fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine.
Research, which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research
institutes MESA+ and MIRA. The faculty works together intensively with industrial partners and researchers in the Netherlands
and abroad and conducts extensive research for external commissioning parties and funders.
