Development of Hyphenated Analytical Techniques using spICP-MS for Online Characterization of Metallic Nanoparticles in Aerosols
The presence of metallic nanoparticles (NPs) in aerosols has raised concern about their fate in the environment through natural processes and anthropological activities. The state-of-the-art technologies for direct aerosol characterization cannot reach rea ...
EPFL2024Nb, Ta and Hf-The tri-dopant tournament for the enhancement of TiO2 photochromism
TiO2 quantum dot (QD) size nanoparticle colloids have shown tremendous photochromic response. Here we show that the of the photochromic response of TiO2 QDs can be further enhanced by doping. Our synthesis approach allows to reach high nominal doping level ...
ELSEVIER SCIENCE SA2023Plasmon-induced near-infrared fluorescence enhancement of single-walled carbon nanotubes
Ardemis Anoush Boghossian, Giulia Tagliabue, Sayyed Hashem Sajjadi, Alessandra Antonucci, Shang-Jung Wu, Theodoros Tsoulos, Amirmostafa Amirjani
Single-walled carbon nanotubes (SWCNTs) emit near-infrared (NIR) fluorescence that is ideal for optical sensing. However, the low quantum yields diminish the sensor’s signal-to-noise ratio and limits the penetration depths for in vivo measurements. In this ...

David Lyndon Emsley, Raffaella Buonsanti, Anna Loiudice, Michael Allan Hope, Ona Segura Lecina, Kevin Rossi, Snaedis Björgvinsdóttir, Amrit Venkatesh
Colloidal atomic layer deposition (c-ALD) enables the growth of hybrid organic/inorganic oxide shells with tunable thickness at the nanometer scale around ligand-functionalized inorganic nanoparticles (NPs). This recently developed method has demonstrated ...
2021Born to be different: the formation process of Cu nanoparticles tunes the size trend of the activity for CO2 to CH4 conversion
We investigate the impact of the formation process of Cu nanoparticles on the distribution of adsorption sites and hence on their activity. Using molecular dynamics, we model formation pathways characteristic of physical synthesis routes as the annealing o ...

Esther Amstad, Alvaro Lino Boris Charlet, Raffaele Mezzenga
Metal-coordinated hydrogels are physical hydrogels entirely crosslinked by complexes between ligand decorated polymers and metal ions. The mechanical properties of these hydrogels strongly depend on the density and dynamics of metal-coordinated interaction ...
2021CO2 chemical transformations using metal-organic frameworks
During the last decades, intensive efforts have been applied to tackle the enormous emissions of CO2 into atmosphere. These efforts include not only developing efficient carbon capture techniques, but also the introduction of new ways to transform the capt ...
EPFL2020Structure-Property Relationships of Microphase-Separated Metallosupramolecular Polymers
The structural, thermomechanical, and viscoelastic properties of metallosupramolecular polymers (MSPs) can be controlled through the choice of the multiligand monomer and the nature of the metal salt from which these materials are assembled. This versatili ...
