X-ray Crystallography

23.7K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

X-ray Diffraction of Biological Samples

3.8K
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...

For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
 Solutions containing organic solvents, such as low-molecular-mass alcohols, esters, or ketones, enhance absorbances by increasing...

Atomic Absorption Spectroscopy: Atomization Methods

Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the...

Area of Science:

  • Materials Science
  • Solid-State Physics
  • Crystallography

Background:

  • Diffuse scattering in X-ray diffraction patterns contains vital information about local atomic structure and disorder in crystalline materials.
  • Pair distribution function (PDF) analysis is a common method for extracting local structural information, but Fourier transforms can introduce aberrations.
  • Distinguishing static and dynamic disorder components from experimental data is challenging.

Purpose of the Study:

  • To develop and validate a novel method for analyzing thermal diffuse scattering directly from X-ray powder patterns.
  • To investigate the local atomic structure and dynamics of silver oxide (Ag₂O) using this new approach.
  • To correlate experimental findings with theoretical calculations for force constants.

Main Methods:

  • Analysis of thermal diffuse scattering directly on X-ray powder patterns using the Rietveld method.
  • Integration of a correlated displacement model for atomic pairs.
  • Experimental data collection using synchrotron radiation and laboratory X-ray diffraction.
  • Application of an Einstein model and density functional theory (DFT) for calculating force constants.
  • Comparison with *ab initio* molecular dynamics simulations.

Main Results:

  • The study successfully analyzed thermal diffuse scattering directly from Ag₂O powder patterns.
  • Experimental force constants obtained using the Einstein model showed good agreement with DFT and *ab initio* simulations.
  • The dynamic structure of Ag₂O was revealed to be complex, with anisotropic phonon dispersion and soft phonon modes.
  • These dynamic features explain the observed significant atomic displacement parameters.

Conclusions:

  • The proposed method offers a direct approach to analyze thermal diffuse scattering, bypassing Fourier transform limitations.
  • The findings elucidate the complex dynamics and local forces within Ag₂O, linked to its structural disorder.
  • This technique is applicable to various binary and complex crystalline systems for understanding local dynamics via X-ray diffraction.
