Postdoc in Molecular Modeling of Mineral Wool (Insulation) Dissolution

Technical University of Denmark



The CHEC research center at the Department of Chemical and Biochemical Engineering invites applicants for a Postdoc position in molecular dynamics simulations of mineral wool dissolution properties. 

The Postdoc 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 loading, 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 modeling 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 Postdoc will set up bulk and surface models for mineral wool material and use molecular dynamics to simulate dissolution processes at the solid-solution interface. Several surface models are needed to model the fundamental dissolution process as a function of 

  • pH in solution
  • solution composition
  • fiber composition

Besides this Postdoc position, the team will consist of a PhD student performing density functional theory calculations, a postdoc collecting surface spectroscopy data to support the modeling and a PhD student based in Australia, who will also use molecular dynamics to model dissolution processes at fiber surfaces . Other researchers 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,

Candidates should have a PhD or equivalent in physics, chemistry, chemical engineering, glass science, materials science or similar quantitative discipline. Experience in molecular dynamics is a requirement.
