In our work, we demonstrate that X-ray photons can initiate a “molecular catapult” effect, leading to the dissociation of chemical bonds and the formation of heavy fragments within just a few femtoseconds. We reconstruct the momenta of fragments from a three-body dissociation in bromochloromethane…

Double-pentagon silicon chains in a quasi-1D Si/Ag(001) surface alloy

Conor Hogan, Andrea Sette, Vasil A Saroka, Stefano Colonna, Roberto Flammini, Laurita Florean, Romain Bernard, Laurence Masson, Geoffroy Prévot, Fabio Ronci

<div><p>Silicon surface alloys and silicide nanolayers are highly important as contact materials in integrated circuit devices. Here we demonstrate that the submonolayer Si/Ag(001) surface reconstruction, reported to exhibit interesting topological properties, comprises a quasi-one-…

Direct observation of the complex S(IV) equilibria at the liquid-vapor interface

Tillmann Buttersack, Ivan Gladich, Shirin Gholami, Clemens Richter, Rémi Dupuy, Christophe Nicolas, Florian Trinter, Annette Trunschke, Daniel Delgado, Pablo Corral Arroyo, Evelyne A Parmentier, Bernd Winter, Lucia Iezzi, Antoine Roose, Anthony Boucly, Luca Artiglia, Markus Ammann, Ruth Signorell, Hendrik Bluhm

The multi-phase oxidation of S(IV) plays a crucial role in the atmosphere, leading to the formation of haze and severe pollution episodes. We here contribute to its understanding on a molecular level by reporting experimentally determined pK a values of the various S(IV) tautomers and reaction…
