Enhanced particle diffusion in fluctuating binary environments
Fivos Perakis, Takeshi Kawasaki, Shinji Saito
We investigate single-particle diffusion in a two-state Langevin model where the friction coefficient randomly switches between low-friction (liquid-like) and high-friction (glassy…
Melting Domain Size and Recrystallization Dynamics of Ice Revealed by Time-Resolved X-ray Scattering
Cheolhee Yang, Marjorie Ladd-Parada, Kyeongmin Nam +13
The phase transition between water and ice is ubiquitous and one of the most important phenomena in nature. Here, we performed time-resolved x-ray scattering experiments capturing…
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…
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…
Brine rejection and hydrate formation upon freezing of NaCl aqueous solutions
Ifigeneia Tsironi, Daniel Schlesinger, Alexander Späh +3
Studying the freezing of saltwater on a molecular level is of fundamental importance for improving freeze desalination techniques. Here, we investigate the freezing process of NaCl…
