Journal ArticleDOI
Molecular simulation study to examine the possibility of detecting collective motion in protein by inelastic neutron scattering
TL;DR: In this article, the shape of the three dynamic structure factors in (Q,ω)-space are in good agreement in high-frequency regions (>10 −meV), but considerably different in low frequency regions.
Journal ArticleDOI
Extending the potential of x-ray free-electron lasers to industrial applications - An initiatory attempt at coherent diffractive imaging on car-related nanomaterials
Rikiya Yoshida,Hisao Yamashige,Masahide Miura,Takashi Kimura,Yasumasa Joti,Yoshitaka Bessho,Mayumi Kuramoto,Jian Yu,Krishna P. Khakurel,Kensuke Tono,Makina Yabashi,Tetsuya Ishikawa,Yoshinori Nishino +12 more
TL;DR: In this article, the SPring-8 Angstrom compact free-electron laser (SACLA) was used for the analysis of car-related nanomaterials.
Journal ArticleDOI

TL;DR: The timescale for crystalline disordering when a nanoparticle is hit with an intense laser pulse scales as the inverse of the speed of ions ejected from the ensuing nanoplasma.
Journal ArticleDOI
Universality and Structural Implications of the Boson Peak in Proteins.
TL;DR: The effect of hydration, temperature, and pressure on the boson peak and volumetric properties of a globular protein are evaluated by using inelastic neutron scattering and molecular dynamics simulation.
Proceedings ArticleDOI
