X-ray Diffraction of Biological Samples01:10

X-ray Diffraction of Biological Samples

4.7K
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

9.8K
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...

  • Integration of a motorized, flexible sample stage for seamless switching between Small-Angle X-ray Scattering (SAXS), Wide-Angle X-ray Scattering (WAXS), and High-Resolution X-ray Diffraction (HR-XRD) modes.
  • Validation of optical performance using SHADOW4 geometric ray-tracing simulations for a Mo/Si multilayer ellipsoidal mirror.

Main Results:

  • The instrument produces a high-quality X-ray beam with a maximum photon flux of 7 × 10^8 photons/s.
  • Optical simulations confirmed 80% reflectivity at a grazing incidence angle of 1.031°, with a focused beam spot size of approximately 1 × 0.5 mm^2.
  • The modular architecture was demonstrated to be a practical and cost-effective solution compared to synchrotron facilities.

Conclusions:

  • The developed laboratory instrument offers versatile X-ray analysis capabilities for diverse materials.
  • This platform supports routine materials characterization across biomedical sciences, materials science, and environmental research.
  • The novel instrument presents a viable alternative to synchrotron facilities for specific research needs.
