In situ Gas-Cell Electron Microscopy Reveals Pressure-Selected Restructuring Pathways in AuRu Ammonia Catalysts
Amy S. McKeown-Green, Parivash Moradifar, Zisheng Zhang +7
Bimetallic catalysts provide new routes toward sustainable ammonia synthesis, but the nanoscale structural dynamics under reaction-relevant conditions remain poorly understood. Her…
A Coordination-Based Model for the Prediction of Surface Energies and the Shape of Metal Particles
Shyama Charan Mandal, Frank Abild-Pedersen
Surface energies of metal-based systems are important for determining the Wulff-constructed shapes of metal nanoparticles and understanding the stability. We have developed a coord…
Single-Ion Sensing in Liquid Using Fluorescent h-BN Point Defects
Yecun Wu, Kun Xu, Hori Pada Sarker +7
Understanding the chemical state of individual ions in solutions is crucial for advancing knowledge of complex systems. However, sensing systems at the single-ion level in liquid e…
Atom-Specific Probing of Electron Dynamics in an Atomic Adsorbate by Time-Resolved X-ray Spectroscopy
Simon Schreck, Elias Diesen, Martina Dell'Angela +25
The electronic excitation occurring on adsorbates at ultrafast time scales from optical lasers that initiate surface chemical reactions is still an open question. Here, we report t…
X-ray Free Electron Laser Studies of Electron and Phonon Dynamics of Graphene Adsorbed on Copper
Hirohito Ogasawara, Han Wang, Jörgen Gladh +23
We report optical pumping and X-ray absorption spectroscopy experiments at the PAL free electron laser that directly probe the electron dynamics of a graphene monolayer adsorbed on…
Ultrafast adsorbate excitation probed with sub-ps resolution XAS
Elias Diesen, Hsin-Yi Wang, Simon Schreck +24
We use a pump-probe scheme to measure the time evolution of the C K-edge X-ray absorption spectrum (XAS) from CO/Ru(0001) after excitation by an ultrashort high-intensity optical l…
