Aerosol source identification in the spring and summertime central Arctic Ocean using high-resolution mass spectrometry during MOSAiC.
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Imad El Haddad, Jakob Boyd Pernov, Hélène Paule Angot, Lubna Dada
The Arctic region is undergoing considerable changes and is warming at a rate three to four times as fast as the rest of the world. Aerosols, which can originate from natural or anthropogenic sources, both of which can be locally emitted or long-range tran ...
2023Numerical and experimental investigations of a microwave interferometer for the negative ion source SPIDER
Ivo Furno, Rémy Jacquier, Riccardo Agnello
The electron density close to the extraction grids and the co-extracted electrons represent a crucial issue when operating negative ion sources for fusion reactors. An excessive electron density in the plasma expansion region can indeed inhibit the negativ ...
IOP Publishing Ltd2023Fragment ion-functional group relationships in organic aerosols using aerosol mass spectrometry and mid-infrared spectroscopy
Satoshi Takahama, Imad El Haddad, Nikunj Dudani, Amir Yazdani
Aerosol mass spectrometry (AMS) and mid-infrared spectroscopy (MIR) are two analytical methods for characterizing the chemical composition of OM. While AMS provides high-temporal-resolution bulk measurements, the extensive fragmentation during the electron ...
European Geosciences Union2022Negative ion density in the ion source SPIDER in Cs free conditions
The SPIDER experiment, operated at the Neutral Beam Test Facility of Consorzio RFX, Padua, hosts the prototype of the H-/D- ion source for the ITER neutral beam injectors. The maximization of the ion current extracted from the source and the minimization o ...
2022Constraining the response factors of an extractive electrospray ionization mass spectrometer for near-molecular aerosol speciation
Julia Schmale, Imad El Haddad, Yandong Tong
Online characterization of aerosol composition at the near-molecular level is key to understanding chemical reaction mechanisms, kinetics, and sources under various atmospheric conditions. The recently developed extractive electrospray ionization time-of-f ...
2021Real-Time Detection of Aerosol Metals Using Online Extractive Electrospray Ionization Mass Spectrometry
Christian Ludwig, Mohamed Tarik, Houssni Lamkaddam
Metal emissions are of major environmental and practical concern because of their highly toxic effects on human health and ecosystems. Current technologies available in the market for their detection are typically limited by a time resolution of 1 h or lon ...
AMER CHEMICAL SOC2020Online Aerosol Chemical Characterization by Extractive Electrospray Ionization-Ultrahigh-Resolution Mass Spectrometry (EESI-Orbitrap)
Current mass spectrometry techniques for the online measurement of organic aerosol (OA) composition are subjected to either thermal/ionization-induced artifacts or limited mass resolving power, hindering accurate molecular characterization. Here, we combin ...
AMER CHEMICAL SOC2020Quasi-Instantaneous Bacterial Inactivation on Cu-Ag Nanoparticulate 3D Catheters in the Dark and Under Light: Mechanism and Dynamics
César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines
The first evidence for Cu-Ag (50%/50%) nanoparticulate hybrid coatings is presented leading to a complete and almost instantaneous bacterial inactivation in the dark (
