Determining the structure of stable and supercooled liquids by high energy X-ray diffraction
The average structure of glass-forming liquids and glasses can be studied by high energy Xray diffraction (HEXRD) and can be directly compared to predictions by simulations. X-rays with high incident energy (>100 keV) are highly penetrating and provide scattering data to high values of scattering vector (up to 30Å). The beam spot sizes are small (typically 50-500 microns) and data acquisition t...
متن کاملX-ray diffraction "fingerprinting" of DNA structure in solution for quantitative evaluation of molecular dynamics simulation.
Solution state x-ray diffraction fingerprinting is demonstrated as a method for experimentally assessing the accuracy of molecular dynamics (MD) simulations. Fourier transforms of coordinate data from MD simulations are used to produce reciprocal space "fingerprints" of atomic pair distance correlations that are characteristic of the ensemble and are the direct numerical analogues of experiment...
متن کاملShort time dynamics of glass-forming liquids
Calculations have been presented for the intermediate scattering function, dynamic structure factor, and dynamic susceptibility of a complex correlated system undergoing relaxation with independent vibrations. The vibrational contribution was approximated by a Debye spectrum, smoothed at high frequency, while the coupling model was used to describe the relaxation. This model asserts for nonpoly...
متن کاملMolecular structure from X-ray diffraction
While there are some developments in structure solution and refinement, these represent gradual improvements rather than fundamental leaps in methodology. An exception is the assessment of crystal quality by X-ray diffraction topography using a dedicated solid-state electronic detector; this is an elegant example where the precise physical nature of the crystal has been studied and analyzed. Si...
متن کامل3 Molecular structure from X-ray diffraction
Recent developments in the determination of molecular structures from X-ray diffraction data are discussed. While the problems associated with chemical crystallography using single crystals have largely been solved, those with structure from powders and of macromolecules are still the subjects of active research. New and improved methods in structure determination in both these fields dominated...
