Transformation of nanomaterials in the environment - Quantifying the dissolution behaviour of nanomaterials

The dissolution of nanomaterials is one of the three most relevant transformation processes: (i) physicochemical transformation, (ii) (hetero-) agglomeration and (iii) dissolution. During the dissolution process, nanomaterials can potentially dissolve completely or only partially, resulting in a different composition, particle shape and size, agglomeration state and crystallinity. Electrolytes, dissolved elements and (inorganic and organic) complexes are able to interact with nanoparticles in the (aquatic) environment changing the nanomaterials' physicochemical properties. Those interactions have an important influence on solubility and dissolution rates. The applicant is expected to improve current static and dynamic methods to determine the solubility and dissolution rates of nanomaterials and to evaluate relevant (environmental) media compositions. In a final step, those improved methods will be validated and submitted as a proposed directive to the Organization for Economic Co-operation and Development (OECD).

The researchers of the department are at the forefront of nanoparticle analysis, behaviour and fate in the natural environment and develop methodologies for nanoparticle analysis. The department operates a unique, well-equipped infrastructure to investigate nanoparticulate processes and analyse nanoparticles in complex aquatic systems and have access to specialized instrumentation in-house or through intensive collaborations on all levels.

Preferred period of employment is 17.02.2020 - 16.02.2022.
