TL;DR: In this article, the authors used x-ray photon correlation spectroscopy to determine the liquid-liquid phase separation dynamics of a model protein solution upon low temperature quenches and find distinctly different dynamical regimes.

TL;DR: In this article, the kinetics of heat-induced gelation and the microscopic dynamics of a hen egg white gel are probed using x-ray photon correlation spectroscopy along with ultrasmall-angle xray scattering, revealing an exponential growth of the characteristic relaxation times followed by an intriguing steady state in combination with a compressed exponential correlation function and a temporal heterogeneity.

TL;DR: This work uses the scattering invariant Q to probe how approaching the glass transition affects the shape of LLPS boundaries in the temperature / volume fraction plane, and non-invasively identifies system-dependent differences for the effect of glass formation on the LLPS boundary.

TL;DR: In this paper, the authors used X-ray photon correlation spectroscopy to study the dynamics and kinetics of a protein solution undergoing liquid-liquid phase separation (LLPS) and demonstrated that in the early stage of spinodal decomposition, the kinetics relaxation is up to 40 times slower than the dynamics.

TL;DR: In this paper , the dynamics of dense antibody protein (Ig-PEG) solutions using megahertz X-ray photon correlation spectroscopy (MHz-XPCS) at the European XFEL were investigated.
