Reaching the yield point of a glass during x-ray irradiation
A solid loaded beyond the yield stress loses its elastic properties and becomes plastic. From
a microscopic point of view, this limit corresponds to the condition where plastic regions …

Stochastic atomic acceleration during the X-ray-induced fluidization of a silica glass
The X-ray-induced, nonthermal fluidization of the prototypical SiO2 glass is investigated by X-
ray photon correlation spectroscopy in the small-angle scattering range. This process is …

Amorphous-amorphous transformation induced in glasses by intense x-ray beams
The atomic displacements induced by an x-ray beam of relatively low energy, ε∼ 8 KeV, are
investigated in pure boron oxide and in a set of sodium silicate glasses by means of x-ray …

X-ray driven and intrinsic dynamics in protein gels
S Timmermann, ND Anthuparambil, A Girelli… - Scientific Reports, 2023 - nature.com
We use X-ray photon correlation spectroscopy to investigate how structure and dynamics of
egg white protein gels are affected by X-ray dose and dose rate. We find that both, changes …
