High-Pressure Cell for the Study of In-Situ Hydrates Using Energy-Dispersive X-ray Diffraction
Journal of Synchrotron Radiation
|September 1, 1996
Abstract:
A high-pressure low-temperature cell has been developed for in-situ diffraction studies of carbon dioxide and propane gas hydrate crystallization. The design and implementation of the cell, which can operate up to 3.5 MPa and down to 253 K, are described. Using synchrotron energy-dispersive X-ray diffraction, the first growth of the hydrate crystals from solution has been successfully observed. The lattice parameters of the hydrate crystals were found to be 11.927 (2) and 17.196 (2) A, respectively.

01:29Determination of Crystal Structures
In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...
01:10X-ray Diffraction of Biological Samples
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
