Disagglomeration_nanoparticle_200X75.jpg

Importance of Disagglomeration Process on the Fate of Manufactured Nanoparticle in Aquatic Systems

  • Funding : Swiss National Fundation (SNF)
  • 2014 – 2015 (completed)
  • We proposed in this research proposal to get an insight into the understanding of the different modes and mechanisms of disagglomeration in presence of natural compounds and conditions representative of aquatic systems. Such a research domain constitutes an important aspect with regards to the risks associated with manufactured nanoparticles by including the possible transformations of the agglomerates they are frequently forming

Importance of Complexation Processes on the Fate, Reactivity and Transport of Manufactured Nanoparticles in Aquatic Systems

  • Funding : Swiss National Fundation (SNF)
  • 2012 – 2014 (completed)
  • We propose in this research proposal to get an insight into the understanding of the relationship between manufactured NP properties and most importantly their resulting stability (dispersion versus aggregation) in conditions representative of aquatic systems

Behavior of manufactured CeO2 Nanoparticles in Aquatic Systems: Coating, Aging and Agglomeration

  • Funding : University of Geneva – DIP
  • 2013 – 2017
  • We propose in this research proposal to get an insight into the behaviour of CeO2 manufactured nanoparticles which are today massively produced by the industry and incorporated in many consumer products. Focus will be made on the interactions between CeO2 nanoparticles and natural compounds as well as the aging processes under variable conditions such as pH

Computer Modeling of Nanoparticle surface charging processes and Heteroagglomeration process.

  • Funding : University of Geneva – DIP
  • 2013 – 2017
  • In this research we are exploring the nanoparticle surface reactivity and charging processes by investigating the impact of the solution chemistry and nanoparticle chemistry. Agglomeration, heteroagglomeration process are also investigated to derive predictive transport models of nanoparticles in the environment (water, soil) by including natural organic matter and inorganic colloids. These fundamental studies are mainly based on computer modelling.
