X-Ray Photon Correlation Spectroscopy Reveals Intermittent Aging Dynamics in a Metallic Glass [PDF]

, 2015
We use coherent X-rays to probe the aging dynamics of a metallic glass directly on the atomic level. Contrary to the common assumption of a steady slowing down of the dynamics usually observed in macroscopic studies, we show that the structural ...

Dynamics of soft nanoparticle suspensions at hard X-ray FEL sources below the radiation-damage threshold

IUCrJ, 2018
The application of X-ray photon correlation spectroscopy (XPCS) at free-electron laser (FEL) facilities enables, for the first time, the study of dynamics on a (sub-)nanometre scale in an unreached time range between femtoseconds and seconds.

Reverse-engineering method for XPCS studies of non-equilibrium dynamics

IUCrJ, 2022
X-ray photon correlation spectroscopy (XPCS) is a powerful tool in the investigation of dynamics covering a broad time and length scale. It has been widely used to probe dynamics for systems in both equilibrium and non-equilibrium states; in particular ...

Scientific Opportunities with an X-ray Free-Electron Laser Oscillator [PDF]

, 2019
An X-ray free-electron laser oscillator (XFELO) is a new type of hard X-ray source that would produce fully coherent pulses with meV bandwidth and stable intensity. The XFELO complements existing sources based on self-amplified spontaneous emission (SASE)

XPC multifaceted roles beyond DNA damage repair: p53-dependent and p53-independent functions of XPC in cell fate decisions

Mutation Research/Reviews in Mutation Research, 2022
Xeroderma pigmentosum group C protein (XPC) acts as a DNA damage recognition factor for bulky adducts and as an initiator of global genome nucleotide excision repair (GG-NER). Novel insights have shown that the role of XPC is not limited to NER, but is also implicated in DNA damage response (DDR), as well as in cell fate decisions upon stress. Moreover,

Structure and dynamics of dense colloidal ellipsoids at the nearest-neighbor length scale

Physical Review Research, 2021
Anisotropic particles are known to exhibit a richer and more complex phase behavior in comparison to their spherical counterpart. While the majority of the existing studies address structural properties, the dynamic behavior of anisotropic particles is a

Static Charge Density Wave Order in the Superconducting State of La2-xBaxCuO4 [PDF]

, 2017
Charge density wave (CDW) correlations feature prominently in the phase diagram of the cuprates, motivating competing theories of whether fluctuating CDW correlations aid superconductivity or whether static CDW order coexists with superconductivity in ...

Applying Feature Detection to XPCS Image Processing

Journal of Physics: Conference Series, 2022
Abstract Sequential X-ray photon correlation spectroscopy (XPCS) reveals sample dynamics by analyzing a series of coherent scattering images, which is often time-consuming. For applications like real-time XPCS analysis, high efficiency is desired. Pixel binning is a straightforward strategy to reduce the processing time, but over-binning

Ion beam sputtered surface dynamics investigated with two-time correlation functions : a model study [PDF]

, 2012
Ion beam sputtering is a widely used technique to obtain patterned surfaces. Despite the large use of this approach on different materials to create surface nanostructures, the theoretical model to explain the time evolution of the erosion process is ...
