PhD position in Molecular Modelling of Mineral Wool (Insulation) Dissolution

The CHEC research center at the department of Chemical and Biochemical Engineering invites applicants for a PhD position in density functional theory modelling of mineral wool dissolution properties.

The PhD position is part of a project sponsored by ROCKWOOL International A/S, where the overall goal is to develop a predictive model for how mineral wool fiber material performs in contact with solution as a function of fiber composition, solution composition, pH and temperature. One of the challenges in a sustainable energy future is to produce insulation that is effective, robust and long lasting, environmentally friendly and safe. The model will contribute to understanding product stability in various situations as well as the biosolubility characteristics of mineral wool fibers. The contribution from molecular modelling is to provide key parameters from fundamental surface processes that contribute to the overall dissolution behavior, which are not easily available through experiments.

Responsibilities and tasks
The PhD student will use density functional theory with the COSMO-RS implicit solvent model to set up models for mineral wool material and calculate and predict the equilibrium surface chemistry as a function of e.g. 

  • pH in solution
  • solution composition
  • fiber composition
Besides this PhD position, the team will consist of a postdoc performing molecular dynamics simulations, a postdoc collecting surface spectroscopy data to support the modelling and a PhD student based in Australia, who will also use molecular dynamics to model dissolution processes at fiber surfaces. Other researchers, working in project with some overlapping interests will also contribute to discussions. Personnel from the ROCKWOOL Group will be deeply involved in the project, both via complementary experiments and general scientific interactions. The project requires close collaboration within the research group and monthly meetings with the ROCKWOOL colleagues. Strong interpersonal skills and English proficiency are important. Motivation, creativity as well as willingness and ability to collaborate with both experimentalists and theoreticians is important.

Qualifications
Candidates should have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.

A first degree in physics, chemistry, chemical engineering, glass science, materials science or similar quantitative discipline and/or experience and a strong interest in quantum chemical calculations is important.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.

Assessment
Applications will be assessed by a committee formed from those most actively involved in the project. Applicants on the short list will be interviewed by skype and the most interesting candidate(s) will potentially be invited for an on-site visit and further discussion. We expect the successful candidate to begin in September but the start date can be adjusted, considering individual circumstances.  Please indicate your preferred start date in your cover letter.
