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

Determination of Crystal Structures

Determination 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...

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...

Summary

Researchers demonstrate a new x-ray scattering method that bypasses the optical diffraction limit. This technique generates cloned x-ray photon twins, enabling self-focused diffraction patterns beyond conventional limits.

Area of Science:

Physics
Optics
X-ray Science

Background:

The optical diffraction limit traditionally defines resolution in imaging.
Conventional x-ray diffraction theory is based on spontaneous scattering.
Circular photon sources are key to understanding diffraction limits.

Purpose of the Study:

To investigate the breakdown of conventional x-ray diffraction theory.
To explore a new x-ray scattering mechanism at high intensities.
To demonstrate self-focused diffraction beyond the conventional limit.

Main Methods:

Utilizing a back-illuminated thin film in a circular aperture as an x-ray source.
Replacing spontaneous x-ray scattering with stimulated resonant scattering at high incident intensity.
