“…And the correlation between the photos are ignored in the small angel X-rat scattering (SAXS) [12,13]. The diffract-before-destroy nature of serial nanocrystallography can be well applied into single-particle and solution scattering [6,[14][15][16][17][18]. Because the CXS can reveal more details information of the molecule's structure in solution as expected by Kam [19,20].…”

Abstract. The correlated X-ray scattering (CXS) was introduced and compared with other methods which were used to study the structures of the biomacromolecules in solution, such as nuclear magnetic resonance (NMR), electron microscope (EM) and small-angle x-ray scattering (SAXS). Then the corrected results of the sum, the mean, the median and the variance of the scattering intensity that we collected from xFEL (x-ray Free Electron Laser) experiments in SACLA were calculated. Furthermore, the density scanning method was used to pick out the useful cluster and the other 28 useless clusters were filtered. Finally, our results will lay a good foundation for the application of correlated X-ray scattering (CXS) in computing the angular correlation of the scattering intensity with the one chosen cluster effectively in future.

The correlated X-ray scattering (CXS) was introduced and compared with other methods which were used to study the structures of the biomacromolecules in solution, such as nuclear magnetic resonance (NMR), electron microscope (EM) and small-angle x-ray scattering (SAXS). Then a key step which was used to filter the scattering data was put forwarded. And some important clusters were obtained with density based scanning method. Finally, the clusters will lay a good foundation in computing the correlation in future.

Methane hydrates can be preserved at ambient pressure, beyond their region of thermodynamic stability, by storing them at temperatures from 240 to 270 K. The origin of this anomalous self-preservation is the formation of an ice coating that covers the clathrate particles and prevents further loss of gas. While there have been several studies on self-preservation, the question of what is the mechanism by which ice nucleates on the decomposing clathrate hydrates has not yet been fully explained. Here, we use molecular simulations, thermodynamic analysis, and nucleation theory to investigate possible scenarios for the nucleation of ice: heterogeneous nucleation at the clathrate/vapor or clathrate/liquid interfaces and homogeneous nucleation from supercooled water. Our results indicate that clathrates cannot heterogeneously nucleate ice and that ice nucleation is due to the cooling of water at the decomposing clathrate/liquid interface, which suffices to trigger homogeneous ice nucleation. We find that the (111) face of the sII structure clathrate can bind to the (111) plane of cubic ice or the basal plane of hexagonal ice through domain matching, resulting in a weak binding that—while insufficient to promote heterogeneous ice nucleation—suffices to produce epitaxy and alignment between these crystals. We use thermodynamic relations, theory, and the contact angles of ice at the (111) sII clathrate/liquid interface to determine—for the first time—the interfacial free energy of this most favorable ice-clathrate interface, 59 ± 5 mJ/m2. We discuss the implications of our results for the feasibility of heterogeneous nucleation of gas clathrates at ice/vapor interfaces.
