X-ray Diffraction of Biological Samples01:10

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 crystal...
X-ray Crystallography02:18

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 Structures01:29

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...

Area of Science:

  • Materials Science
  • Polymer Science
  • Wood Science

Background:

  • Bamboo is a sustainable material with diverse applications.
  • Understanding the effects of gamma irradiation on bamboo's properties is crucial for material processing and development.
  • Gamma irradiation is a potential method for modifying lignocellulosic materials.

Purpose of the Study:

  • To investigate the impact of gamma irradiation on the microfibril angle and crystallinity of bamboo.
  • To determine the relationship between irradiation dose and changes in bamboo's structural properties.
  • To assess the influence of these structural changes on the physical-mechanical properties of bamboo.

Main Methods:

  • Bamboo samples were subjected to varying doses of gamma irradiation.
  • X-ray diffraction (XRD) was employed to analyze microfibril angle and crystallinity.
  • Physical-mechanical properties were evaluated in relation to structural changes.

Main Results:

  • Bamboo crystallinity initially increased with irradiation doses below 100 kGy.
  • Crystallinity decreased when irradiation doses reached approximately 100 kGy.
  • Microfibril angle showed no significant changes throughout the irradiation process.

Conclusions:

  • Gamma irradiation dose-dependently alters bamboo's crystallinity.
  • Microfibril angle is not a primary factor influencing property variations post-irradiation.
  • The findings provide insights into optimizing gamma irradiation for bamboo modification.
