Acyl-Ethynylbenziodoxolone (acyl-EBX): Access to Ketene Dithioarylacetals
Jérôme Waser, Pierre Gérard Joseph Palamini, Morgane Elodie Marie Delattre, Julien Aymeric Borrel, Maël Djaïd
We report the synthesis of ketene dithioarylacetals in 40–97% yield using thiophenols and acyl-EBXs (ethynylbenziodoxolones) generated in situ from a common hypervalent iodine precursor and alkynyl trifluoroborate salts. The products could be further modif ...
2023Iodine oxoacids enhance nucleation of sulfuric acid particles in the atmosphere
Andrea Baccarini, Imad El Haddad, Mihnea Surdu, Lubna Dada, André Welti, Houssni Lamkaddam
The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H2SO4), stabilized by ammonia (NH3). However, in marine and polar regions, NH3 is generally low, and H2SO4 is frequently found together with iodine oxoacids [HIOx, i.e., iodic acid ...
2023Understanding the growth mechanism of BaZrS3 chalcogenide perovskite thin films from sulfurized oxide precursors
Anna Fontcuberta i Morral, Elias Zsolt Stutz, Andrea Giunto, Santhanu Panikar Ramanandan, Mirjana Dimitrievska, Iléane Tiphaine Françoise Marie Lefevre
Barium zirconium sulfide (BaZrS3) is an earth-abundant and environmentally friendly chalcogenide perovskite with promising properties for various energy conversion applications. Recently, sulfurization of oxide precursors has been suggested as a viable sol ...
IOP Publishing Ltd2023One-pot synthesis of functionalized bis(trifluoromethylated)benziodoxoles from iodine(i) precursors
Jérôme Waser, Xingyu Liu, Nieves Pilar Ramirez Hernandez, Tobias Michael Milzarek
Bis(trifluoromethylated)benziodoxoles (Bx) are broadly used cyclic hypervalent iodine reagents due to their stability and unique chemical properties. However, current methods to access them require several steps and long reaction times, making their synthe ...
2023Peptide-Hypervalent Iodine Reagent Chimeras: Enabling Peptide Functionalization and Macrocyclization
Jérôme Waser, Christian Heinis, Xinjian Ji, Xingyu Liu
Herein, we report a novel strategy for the modification of peptides based on the introduction of highly reactive hypervalent iodine reagents-ethynylbenziodoxolones (EBXs)-onto peptides. These peptide-EBXs can be readily accessed, by both solution- and soli ...
WILEY-V C H VERLAG GMBH2023Poisoning Effects of Cerium Oxide (CeO2) on the Performance of Proton Exchange Membrane Fuel Cells (PEMFCs)
Jan Van Herle, Hossein Pourrahmani
In this study, the poisoning effects of cerium oxide (CeO2) as the contaminant on the performance of proton exchange membrane fuel cells (PEMFCs) are evaluated. An experimental setup was developed to analyze the performance characteristic (I-V) curves in c ...
MDPI2022Investigation of new particle formation mechanisms and aerosol processes at Marambio Station, Antarctic Peninsula
Understanding chemical processes leading to the formation of atmospheric aerosol particles is crucial to improve our capabilities in predicting the future climate. However, those mechanisms are still inadequately characterized, especially in polar regions. ...
COPERNICUS GESELLSCHAFT MBH2022Integrated Aerodynamic/Electrochemical Microsystem for Collection and Detection of Nanogram-level Airborne Bioaccessible Metals
Jian Wang, Christian Ludwig, Tianyu Cen, Jiukai Tang
The soluble fraction of aerosol particulate matter containing trace metals has the potential to engender toxicity and exacerbate the adverse health effects of particulate matter. In this study, an inertial-impaction-based fluidic chip integrated with elect ...
2022The role of NH3 and DMA in new particle formation from ambient measurements, bias exchange metadynamics and reactive MD simulations
Athanasios Nenes, Satoshi Takahama, Spyros Pandis, Mária Lbadaoui-Darvas
Ammonia (NH3) and organic amines (dimethyl amine, DMA) play an important role in the heteromolecular nucleation of sulfuric acid (H2SO4) and water. Nucleation rates depend on their concentrations. Extremely low amine concentrations can increase nucleation ...
2021Low‐Volatility Vapors and New Particle Formation Over the Southern Ocean During the Antarctic Circumnavigation Expedition
Julia Schmale, Andrea Baccarini, Robin Lewis Modini
During summer, the Southern Ocean is largely unaffected by anthropogenic emissions, which makes this region an ideal place to investigate marine natural aerosol sources and processes. A better understanding of natural aerosol is key to constrain the preind ...
