$X-ray Diffraction of Biological Samples$ 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...

X-ray Imaging

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

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...

Area of Science:

Materials Science
Condensed Matter Physics
High-Energy Physics

Background:

Studying material behavior under high strain rates is crucial for understanding dynamic extremes.
Existing methods often lack the resolution or simultaneity to capture rapid deformation and fracture processes.
Advanced synchrotron X-ray techniques offer potential for in-situ, high-speed material analysis.

Purpose of the Study:

To develop and validate a novel mini gas gun system for simultaneous X-ray diffraction and imaging.
To investigate the dynamic response of single-crystal sapphire under high strain-rate loading.
To quantify lattice deformation and fracture mechanisms during dynamic impact events.

Main Methods:

A mini gas gun system was integrated with synchrotron X-ray pulses at beamline 32-ID.
A modified target chamber design enhanced reciprocal space coverage for a small-area detector.
High-speed cameras synchronized with X-ray pulses enabled multiframe imaging and diffraction analysis.

Main Results:

Simultaneous X-ray diffraction and imaging captured lattice deformation and fracture in real-time.
Fracture was characterized by sequential splitting and wing crack formation.
Broadened diffraction peaks suggest increased mosaic spread within the material during impact.

Conclusions:

The developed mini gas gun system is effective for multiscale measurements of high strain-rate phenomena.
This technique provides unprecedented insights into dynamic material behavior at extreme conditions.
Further applications can advance the understanding of materials under shock loading and impact.
