High-pressure X-ray photon correlation spectroscopy at fourth-generation synchrotron sources [PDF]

Journal of Synchrotron Radiation
A new experimental setup combining X-ray photon correlation spectroscopy (XPCS) in the hard X-ray regime and a high-pressure sample environment has been developed to monitor the pressure dependence of the internal motion of complex systems down to the ...

Analysis Strategies for MHz XPCS at the European XFEL [PDF]

Applied Sciences, 2021
The nanometer length-scale holds precious information on several dynamical processes that develop from picoseconds to seconds. In the past decades, X-ray scattering techniques have been developed to probe the dynamics at such length-scales on either ...

Coherent X-rays reveal anomalous molecular diffusion and cage effects in crowded protein solutions [PDF]

Nature Communications
Understanding protein motion within the cell is crucial for predicting reaction rates and macromolecular transport in the cytoplasm. A key question is how crowded environments affect protein dynamics through hydrodynamic and direct interactions at ...

XPC protects against smoking- and carcinogen-induced lung adenocarcinoma [PDF]

Carcinogenesis, 2019
Cigarette smoke (CS) contains hundreds of carcinogens and is a potent inducer of oxidative and bulky DNA damage, which when insufficiently repaired leads to activation of DNA damage response and possibly mutations. The DNA repair protein xeroderma pigmentosum group C (XPC) is primed to play an important role in CS-induced DNA damage because of its ...
