X-ray Crystallography

X-ray Crystallography

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...

$X-ray Diffraction of Biological Samples$ 01:10

X-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...

NMR Spectrometers: Resolution and Error Correction

NMR Spectrometers: Resolution and Error Correction

When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Background:

Bragg coherent X-ray diffraction imaging (BCDI) is vital for nanometre-scale crystal analysis.
Angular distortions during data acquisition limit BCDI's applicability, especially for small crystals and high-flux X-ray beams.

Purpose of the Study:

To develop and validate a pre-processing algorithm for correcting large angular distortions in BCDI datasets.
To improve the accuracy of strain imaging and morphology reconstruction in BCDI.

Main Methods:

A novel pre-processing algorithm was developed to recover 3D datasets from BCDI data affected by angular distortions.
The algorithm's performance was systematically evaluated across various distortion levels.

Main Results:

The algorithm successfully recovered correct angles for distortions up to 16.4 times the angular step size (dθ = 0.004°).
High accuracy was achieved in recovering angles from continuous scans.
Significant improvements in subsequent phase retrieval were observed after correction.

Conclusions:

The developed algorithm effectively corrects for large angular distortions in BCDI data.
This method broadens the applicability of BCDI for nanometre-scale crystal imaging, particularly under challenging experimental conditions.
