Surface-induced vibrational energy redistribution in methane/surface scattering depends on catalytic activity

Rainer Beck, Christopher Scott Reilly, Patrick Floss

Recent state-to-state experiments of methane scattering from Ni(111) and graphene-covered Ni(111) combined with quantum mechanical simulations suggest an intriguing correlation between the surface-induced vibrational energy redistribution (SIVR) during the ...

Year-round trace gas measurements in the central Arctic during the MOSAiC expedition

Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot

Despite the key role of the Arctic in the global Earth system, year-round in-situ atmospheric composition observations within the Arctic are sparse and mostly rely on measurements at ground-based coastal stations. Measurements of a suite of in-situ trace g ...

Taming Hypervalent Bonds and Strained Rings for Catalysis and Synthesis

Jérôme Waser, Reto Frei, Florian Patrick Marie Daniel De la Barre De Nanteuil, Yifan Li, Sophie Lucie Racine, Maria Victoria Vita, Eloísa Sofía Serrano Robledo

Improving the synthesis of complex organic molecules is essential for progress in many fields such as medicine, agrochemicals or materials. Since 2007, our laboratory has been focusing on the development of non-classical bond disconnections based on the us ...

Mass density of individual cobalt nanowires

Dongfeng Zhang

The mass density of nanowires is determined using in situ resonance frequency experiments combined with quasi-static nanotensile tests. Our results reveal an average mass density of 7.36 g/cm3, which is below the theoretical density of bulk cobalt. The res ...

Coupling CFD and chemical kinetics: examples Fire II and TITAN aerocapture

Pénélope Leyland

The investigation of the thermochemical field around planetary reentry capsules, and their experimental scaled models is made by coupling aerothermodynamic simulation of the corresponding flow field to a library of chemical kinetics of the specific atmosph ...

Disentangling oil weathering using GCxGC. 1. Chromatogram analysis

Jeremy Samuel Arey

Historically, the thousands of compounds found in oils constituted an “unresolved complex mixture” that frustrated efforts to analyze oil weathering. Moreover, different weathering processes inflict rich and diverse signatures of compositional change in oi ...
