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…
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…
X-ray Diffraction and Molecular Dynamics Study of Medium-range Order in Ambient and Hot Water
Congcong Huang, K. T. Wikfeldt, D. Nordlund +5
We have developed x-ray diffraction measurements with high energy-resolution and accuracy to study water structure at three different temperatures (7, 25 and 66 C) under normal pre…
Spatially Inhomogeneous Bimodal Inherent Structure in Simulated Liquid Water
K. T. Wikfeldt, A. Nilsson, L. G. M. Pettersson
In the supercooled regime at elevated pressure two forms of liquid water, high-density (HDL) and low-density (LDL), have been proposed to be separated by a coexistence line ending…
Ab initio van der Waals interactions in simulations of water alter structure from mainly tetrahedral to high-density-like
Andreas Møgelhøj, André Kelkkanen, K. Thor Wikfeldt +7
The structure of liquid water at ambient conditions is studied in ab initio molecular dynamics simulations using van der Waals (vdW) density-functional theory, i.e. using the new e…
