Low-frequency vibrational modes and infrared absorbance of red, blue and green opsin
TL;DR: It is demonstrated that terahertz spectroscopy of low-frequency modes might be relevant for identifying those vibrational degrees of freedom that correlate to known conformational changes in opsins, and the density of states profile of blue opsin in a solvent has increased populations in the very lowest frequency modes.
Making channeling visible: keV noble gas ion trails on Pt(111)
Alex Redinger,Sebastian Standop,Yudi Rosandi,Yudi Rosandi,Herbert M. Urbassek,Thomas Michely +5 more
TL;DR: In this article, the impact of argon and xenon noble gas ions on Pt(111) in grazing incidence geometry is studied through direct comparison of scanning tunneling microscopy images and molecular dynamics simulations.

Tight-binding simulation of liquid and amorphous Si at zero pressure
TL;DR: Using a parametrization of the tight-binding Hamiltonian which includes s, p, and d orbitals, the authors simulate liquid Si; it has the experimental density at zero pressure.

High-energy ion impacts into the sulfur-bearing ice surface of Europa: an atomistic study of chemical transformations
TL;DR: In this paper, the chemical alteration of the surface due to a 20 MeV sulfur ion impact, for which the most pronounced effects are expected, and monitor the chemical transformations occurring inside the ice.
Transmission of low-energy oxygen ions through ultrathin rare-gas films: Molecular-dynamics simulation.
TL;DR: In this paper, the authors simulate a recent experiment by Sack et al. in which oxygen ions are desorbed by electron impact from a small radius and their transmission through rare-gas films of a few monolayer thickness has been measured.
