Liquid-liquid phase separation precedes crystallization in supercooled water-glycerol solutions
Iason Andronis, Sharon Berkowicz, Mariia Filianina +10
Understanding the structural evolution of supercooled water-glycerol solutions is important for cryopreservation, yet distinguishing liquid-state transformations from ice crystalli…
X-ray photon correlation spectroscopy of hydrated lysozyme at elevated pressures
Milla Åhlfeldt, Maddalena Bin, Anita Girelli +12
Pressure provides a powerful parameter to control the protein conformation state, which at sufficiently high values can lead to unfolding. Here, we investigate the effects of incre…
Coherent X-ray Scattering Reveals Nanoscale Fluctuations in Hydrated Proteins
Maddalena Bin, Mario Reiser, Mariia Filianina +15
Hydrated proteins undergo a transition in the deeply supercooled regime, which is attributed to rapid changes in hydration water and protein structural dynamics. Here, we investiga…
In-situ Characterization of Crystallization and Melting of Soft, Thermoresponsive Microgels by Small-Angle X-ray Scattering
Dmitry Lapkin, Nastasia Mukharamova, Dameli Assalauova +8
Depending on the volume fraction and interparticle interactions, colloidal suspensions can form different phases, ranging from fluids, crystals, and glasses to gels. For soft micro…
Gelation dynamics upon pressure-induced liquid-liquid phase separation in a water-lysozyme solution
M. Moron, A. Al-Masoodi, C. Lovato +9
Employing X-ray photon correlation spectroscopy we measure the kinetics and dynamics of a pressure-induced liquid-liquid phase separation (LLPS) in a water-lysozyme solution. Scatt…
Using low dose X-ray Speckle Visibility Spectroscopy to study dynamics of soft matter samples
Johannes Möller, Mario Reiser, Jörg Hallmann +10
We demonstrate the successful application of X-ray Speckle Visibility Spectroscopy (XSVS) experiments to study the dynamics of radiation sensitive, biological samples with unpreced…
Automated matching of two-time X-ray photon correlation maps from protein dynamics with Cahn-Hilliard type simulations using autoencoder networks
S. Timmermann, V. Starostin, A. Girelli +10
We use machine learning methods for an automated classification of experimental XPCS two-time correlation functions from an arrested liquid-liquid phase separation of a protein sol…
Interplay between Kinetics and Dynamics of Liquid-Liquid Phase Separation in a Protein Solution Revealed by Coherent X-ray Spectroscopy
Anastasia Ragulskaya, Nafisa Begam, Anita Girelli +7
Microscopic dynamics of complex fluids in the early stage of spinodal decomposition (SD) is strongly intertwined with the kinetics of structural evolution, which makes a quantitati…
Nanoscale Rigidity in Cross-Linked Micelle Networks Revealed by XPCS Nanorheology
M. Reiser, J. Hallmann, J. Möller +11
Solutions of wormlike micelles can form cross-linked networks on microscopic length scales. The unique mechanical properties of these complex fluids are driven by the interplay bet…
Wave vector dependence of the dynamics in supercooled metallic liquids
B. Ruta, S. Hechler, N. Neuber +13
We present a detailed investigation of the wave vector dependence of collective atomic motion in Au49Cu26.9Si16.3Ag5.5Pd2.3 and Pd42.5Cu27Ni9.5P21 supercooled liquids close to the…
