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 ...
EPFL2024The simultaneous Selective Catalytic Reduction of N2O and NO over Fe-exchanged zeolites
Iron-exchanged zeolites are industrial heterogeneous catalysts deployed to remediate anthropogenic emissions of both nitrous oxide (N2O) and nitrogen oxides (NOx = NO + NO2). Despite the extensive scientific attention received, limited knowledge is availab ...
EPFL2024Seasonal Aerosol Acidity, Liquid Water Content and Their Impact on Fine Urban Aerosol in SE Canada
Athanasios Nenes, Andrea Mario Arangio
This study explores the drivers of aerosol pH and their impact on the inorganic fraction and mass of aerosol in the S.E. Canadian urban environments of Hamilton and Toronto, Ontario. We find that inter-seasonal pH variability is mostly driven by temperatur ...
MDPI2022Electrochemical imaging of metabolic activity in tissue and biofilms
Non-invasive and semi-invasive bioimaging is of great interest for the rapid diagnosis and efficient as well as specific treatments of biological systems affecting human health, such as cancer tissue and biofilms. Electrochemical bioimaging is one of the d ...
EPFL2022Diamine Synthesis via the Nitrogen-Directed Azidation of sigma- and pi-C-C Bonds
Diamines are essential building blocks for the synthesis of agrochemicals, drugs, and organic materials, yet their synthesis remains challenging, as both nitrogens need to be differentiated and diverse substitution patterns (1,2, 1,3, or 1,4) are required. ...
AMER CHEMICAL SOC2021Aerosol pH and liquid water content determine when particulate matter is sensitive to ammonia and nitrate availability
Athanasios Nenes, Spyros Pandis
Nitrogen oxides (NOx) and ammonia (NH3) from anthropogenic and biogenic emissions are central contributors to particulate matter (PM) concentrations worldwide. The response of PM to changes in the emissions of both compounds is typically studied on a case- ...
2020Surface functionalization of metal oxide harmonic nanoparticles for targeted cancer imaging
Cancer is a major health burden worldwide and the leading cause of death in industrialized countries. Early detection is a primary factor of survival and remission rate. Classical imaging methods such as magnetic resonance imaging, ultrasound imaging and m ...
EPFL2020Palladium-Catalyzed Synthesis of Ketenimines from Isocyanides and Synthetic Studies Towards the Total Synthesis of Mersilongine
In the first chapter of this thesis, the development of two new reactions for the synthesis of vinyl ketenimines and alpha-oxo-ketenimines from isocyanides is presented. These palladium-catalyzed transformations both feature an isocyanide insertion / beta- ...
EPFL2019Copper-Catalyzed Three-Component Carboazidation of Alkenes with Acetonitrile and Sodium Azide
Qian Wang, Jieping Zhu, Ala Bunescu, Minh Tu Ha
A copper-catalyzed three-component reaction of alkenes, acetonitrile, and sodium azide afforded gamma-azido alkyl nitriles by formation of one C(sp3)-C(sp3) bond and one C(sp3)-N bond. The transformation allows concomitant introduction of two highly versat ...
