Radiolabeling of Micro-/Nanoplastics via In-Diffusion
Autor: Alexandra Stricker, Stephan Hilpmann, Alexander Mansel, Karsten Franke, Stefan Schymura
Publikováno v: Nanomaterials, Vol 13, Iss 19, p 2687 (2023)
Micro- and nanoplastics are emerging pollutants with a concerning persistence in the environment. Research into their environmental impact requires addressing challenges related to sensitively and selectively detecting them in complex ecological medi

Heterogeneous Sorption of Radionuclides Predicted by Crystal Surface Nanoroughness
Autor: Thorsten Stumpf, Konrad Molodtsov, Paul Chekhonin, Till Bollermann, Tao Yuan, Cornelius Fischer, Moritz Schmidt, Stefan Schymura
Publikováno v: Environmental Science & Technology 55(2021)23, 15797-15809
Reactive transport modeling (RTM) is an essential tool for the prediction of contaminants' behavior in the bio- and geosphere. However, RTM of sorption reactions is constrained by the reactive surface site assessment. The reactive site density variab

Molecular-Level Speciation of Eu(III) Adsorbed on a Migmatized Gneiss As Determined Using μTRLFS
Autor: Milan Zuna, Konrad Molodtsov, Maximilian Demnitz, Moritz Schmidt, Stefan Schymura, Václava Havlová, Filip Jankovský
Publikováno v: Environmental Science & Technology. 55:4871-4879
The interaction of Eu(III) with thin sections of migmatized gneiss from the Bukov Underground Research Facility (URF), Czech Republic, was characterized by microfocus time-resolved laser-induced luminescence spectroscopy (μTRLFS) with a spatial reso

Dissolution-based uptake of CeO2 nanoparticles by freshwater shrimp – a dual-radiolabelling study of the fate of anthropogenic cerium in water organisms
Autor: Aleš Lapanje, Sandra Drev, Rok Podlipec, Seniha Simale Su Uygan, Marko Štrok, Stefan Schymura, Iaroslav Rybkin, Tomaz Rijavec, Karsten Franke, Alexander Mansel
Publikováno v: Environmental Science: Nano
Manufactured nanoparticles, such as CeO2, give rise to novel risks when released into the environment. To assess these risks it is important to quantify the nanoparticle mass flows, as well as their speciation and the mechanisms of their transformati

Mechanistic understanding of Curium(III) sorption on natural K-feldspar surfaces
Autor: Maximilian Demnitz, Stefan Schymura, Julia Neumann, Moritz Schmidt, Thorsten Schäfer, Thorsten Stumpf, Katharina Müller
Publikováno v: Science of the Total Environment 843(2022), 156920
To assess a reliable safety case for future deep underground repositories for highly active nuclear waste the retention of radionuclides by the surrounding host rock must be understood comprehensively. Retention is influenced by several parameters su

Spatially resolved sorption of Cm(III) on crystalline rock: influence of surface roughness and mineralogy
Autor: Ariette Schierz, Maximilian Demnitz, Stefan Schymura, Konrad Molodtsov, Moritz Schmidt, Katharina Müller
Publikováno v: Goldschmidt Virtual 2021, 08.07.2021, Lyon, France
Interdisciplinary research symposium On the safety of nuclear disposal practices 2021, 10.-12.11.2021, Berlin, Germany
Many countries will use deep geological repositories to dispose of highly active nuclear waste. Crystalline rock is a potential host rock because of its strong geotechnical stability, low permeability and low solubility; however, its inherent mineral

Publikováno v: Journal of Hazardous Materials 423(2021)Part A, 127006
Crystalline rock is one of the host rocks considered for a future deep geological repository for highly active radiotoxic nuclear waste. The safety assessment requires reliable information on the retention behavior of minor actinides. In this work, w

Elucidating the Role of Dissolution in CeO2 Nanoparticle Plant Uptake by Smart Radiolabeling
Autor: Stefan Schymura, Heike Hildebrand, Thomas Fricke, Karsten Franke
Publikováno v: Angewandte Chemie International Edition. 56:7411-7414
The identification of major uptake pathways in plants is an important factor when evaluating the fate of manufactured nanoparticles in the environment and the associated risks. Using different radiolabeling techniques we were able to show a predomina
