At NTNU, creating knowledge for a better world is the vision that unites our 7 400 employees and 42 000 students.

We are looking for dedicated employees to join us.

About the position

We have a vacancy for a researcher in the Materials Group at the Department of Mechanical and Industrial Engineering.

The materials group deals with applications of materials science: engineering materials and surfaces with desirable properties for specific applications. The group consists of an interdisciplinary mixture of engineers, physicists, and chemists. We have many industrial and international academic collaborations and aim to provide a stimulating environment for young scientists.

The project for this post doctoral research position is concerned with understanding and modelling the viscosity of complex fluids, particularly polar fluids, ionic liquids, and electrolyte solutions. Viscosity of fluids arises from the nonlinear interactions between molecules at the nano scale.

The goal of this project is to link these microscopic dynamics to the macroscopic transport properties of the fluid. To this end, you will make use of both numerical methods, specifically molecular-dynamics simulations, and analytical approaches using kinetic theory. Along with this, there will be close interaction with experimental and theoretical groups in Trondheim, Stockholm and at Imperial College London.

The focus of this project is on electrolytes (salts): water-based electrolyte solutions and ionic liquids, which are liquid salts. These systems are becoming a new frontier in friction research and are very promising for low-friction applications, as demonstrated for instance by the amazing effectiveness with which water-based synovial fluid lubricates our joints. To make full use of these possibilities, we need more general understanding of the transport properties of these complex liquids. The aim of this project is to develop this understanding as well as practical methods for calculating the viscosity and other transport properties.

The position reports to supervisor Associate Professor.

Duties of the position

  • develop new theory for the viscosity of complex fluids
  • construct and perform molecular-dynamics simulations of models of complex fluids with various level of detail to compare with the theory
  • compare theoretical and simulation results to experimental data

Required selection criteria

  • a PhD in material science, physics, chemistry, or engineering on similar field
  • affinity for analytical or numerical modelling on atomic or molecular scales, preferably with mathematical theory or Molecular-Dynamics / Monte-Carlo simulations
  • good written and oral English language skills

Preferred selection criteria

  • experience with atomic-scale modelling of transport or fluids
  • evidence of scientific creativity as demonstrated for example by a sound publication record in internationally respected peer-reviewed journals

Personal characteristics

  • highly motivated, with enthusiasm for applied theoretical research
  • be able to work both in a research team as well as carry out personal research projects
  • good interpersonal skills
  • strong analytical skills

In the assessment of the best qualified applicant, we will emphasize education, experience and personal suitability as well as your motivation for the position.
