This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

The structure of molecules, particularly the dynamic changes in structure, plays an essential
role in understanding physical and chemical phenomena. Time-resolved (TR) scattering …

Understanding high-velocity impact, and the subsequent high strain rate material
deformation and potential catastrophic failure, is of critical importance across a range of …

The response of materials under dynamic compression involves a complex interplay of
various deformation mechanisms aimed at relieving shear stresses, yielding a remarkable …

The prototypical α→ ω phase transition in zirconium is an ideal test bed for our
understanding of polymorphism under extreme loading conditions. After half a century of …

With large-scale non-equilibrium molecular dynamics simulations and in situ x-ray diffraction
analysis, we conducted a systematic investigation into the effects of pre-existing shear strain …

There has been much controversy over the behavior of zirconium under shock strong
enough to cause the pressure-induced hcp→ ω phase transformation. Due to the short time …

The plasticity and α→ ω transformation are important for the toughness and ductility of hcp
titanium under shock loading. However, three questions remain outstanding:(i) what …

[en] This is not a typical External Report--It is a Handbook. No Abstract is involved. This
includes both Parts 1 and 2. The Metallic Fuels Handbook summarizes currently available …

We systematically study the plasticity and melting behavior in shock loading, as well as their
dependence on porosity (ϕ) and specific surface area (γ) for nanoporous copper (NPC), by …
