X-ray Diffraction of Biological Samples01:10

X-ray Diffraction of Biological Samples

3.9K
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...

X-ray Crystallography

24.0K
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...

Electrostatic Boundary Conditions in Dielectrics

1.3K
When an electric field passes from one homogeneous medium to another, crossing the boundary between the two mediums imparts a discontinuity in the electric field. This results in electrostatic boundary conditions that depend on the type of mediums the field propagates through.
Consider a case where both the mediums across a boundary are two different dielectric materials. Recall that the electric field and electric displacement are proportional and related through the material's...

The de Broglie Wavelength

26.0K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Area of Science:

  • Materials Science
  • Crystallography
  • Computational Materials Science

Background:

  • Electron backscatter diffraction (EBSD) is vital for materials characterization.
  • Identifying crystallographic defects with EBSD remains challenging due to limited understanding of defect diffraction patterns.

Purpose of the Study:

  • To simulate EBSD patterns for FCC-Fe with edge and screw dislocations.
  • To reveal the correlation between dislocation structures and EBSD patterns.

Main Methods:

  • Revised Real Space (RRS) method for simulating EBSD patterns.
  • Analysis of EBSD patterns for FCC-Fe containing edge dislocation dipoles and screw dislocation quadrupoles.

Main Results:

  • Dislocations degrade overall EBSD pattern quality.
  • Specific Kikuchi bands and poles show distinct changes (sharpness, blurring) related to dislocation type and orientation.
  • Anisotropic blurring observed in certain Kikuchi bands.

Conclusions:

  • EBSD patterns can be simulated using electron diffraction dynamics.
  • The study provides theoretical guidance for resolving dislocation structures using EBSD.
  • Established a link between dislocation characteristics and EBSD pattern features.
