Adsorption of Copper by Naturally and Artificially Aged Polystyrene Microplastics and Subsequent Release in Simulated Gastrointestinal Fluid
Florian Frédéric Vincent Breider, Thibault Béranger Masset, Lu Zhou
Microplastics, especially aged microplastics can become vectors of metals from environment to organisms with potential negative effects on food chain. However, a few studies focused on the bioavailability of adsorbed metals and most studies related to aged ...
2024Gas/Surface reactions probed by reflection absorption infrared spectroscopy
In my thesis, I present an investigation of the dissociation reactions of gas phase molecules on single crystal metal surfaces studied by a molecular beam in combination with Reflection Absorption Infrared Spectroscopy (RAIRS). Two gas/surface systems were ...
EPFL2023Deposition freezing, pore condensation freezing and adsorption: three processes, one description?
Athanasios Nenes, Mária Lbadaoui-Darvas
Heterogeneous ice nucleation impacts the hydrological cycle and climate through affecting cloud microphysical state and radiative properties. Despite decades of research, a quantitative description and understanding of heterogeneous ice nucleation remains ...
Gottingen2023Adsorption of Copper by Naturally and Artificially Aged Microplastics and Subsequent Release in Simulated Gastrointestinal Fluid
Florian Frédéric Vincent Breider, Thibault Béranger Masset, Lu Zhou
Microplastics, especially aged microplastics can become vectors of heavy metals from environment to organisms with potential negative effects on food chain. However, a few studies focused on the bioavailability of adsorbed metals and most studies related t ...
ChemRxiv2023Adsorption of HPDX and CaHPOx (x=1, ...,4) molecules on anatase TiO2 (001) surfaces
perform DFT calculations within the COSMO framework to study the adsorption properties of the CaHPOx (x = 1,...,4) phosphate family, and of the related HPOx acids, on a paradigmatic anatase (001) surface. Of particular interest is CaHPO4, a precursor of hy ...
ELSEVIER SCIENCE BV2019Two dimensional diffusion-controlled triplet–triplet annihilation kinetics
Hubert Girault, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet, Grégoire Clément Gschwend, Morgan Kazmierczak
Diffusion controlled chemical reactions are usually observed in three dimensionalmedia. In contrast, planar bimolecular reactions taking place between reagents adsorbed at a soft interface are two-dimensional and therefore cannot be studied within the same ...
2019Adsorption Free Energy of Single Amino Acids at the Rutile (110)/ Water Interface Studied by Well-Tempered Metadynamics
Paul Bowen, Ulrich Aschauer, Azade Yazdan Yar
Single amino acids are present in blood plasma and are the building blocks of larger organic residues. Their interaction with surfaces is therefore crucial for biomedical applications in contact with blood. In this work, we use well-tempered metadynamics t ...
2018Oxygen enriched network-type carbon spheres for multipurpose water purification applications
Potassium hydroxide (KOH) modified network-type carbon spheres (CSs) with abundant oxygen-rich groups were synthesized using a simple hydrothermal carbonization (HTC) of glucose precursor and utilized for the adsorptive removal of cadmium(II) heavy metal a ...
ELSEVIER SCIENCE BV2018Adsorption of thiophene by activated carbon: A global sensitivity analysis
The removal of sulfur compounds in biomass gasification processes is crucial to protect downstream equipment. While conventional sorbent materials can retain H2S, many fail to capture heterocyclic sulfur compounds such as thiophene (C4H4S). This work explo ...
Elsevier Sci Ltd20174 f occupancy and magnetism of rare-earth atoms adsorbed on metal substrates
Harald Brune, Stefano Rusponi, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Aparajita Singha, Romana Baltic, Sebastian Stepanow
We report x-ray absorption spectroscopy and x-ray magnetic circular dichroism measurements as well as multiplet calculations for Dy, Ho, Er, and Tm atoms adsorbed on Pt(111), Cu(111), Ag(100), and Ag(111). In the gas phase, all four elements are divalent a ...
