We developed a novel ultra-small-angle X-ray scattering apparatus for analyzing particle distribution in turbid systems. This advanced technique detects density fluctuations from nanometers to micrometers, overcoming limitations of traditional methods.

Area of Science:

  • Materials Science
  • Physics
  • Chemistry

Background:

  • Conventional light-scattering and microscopic methods have limitations in studying particle distribution in turbid systems.
  • Investigating density fluctuations at the nanoscale is crucial for understanding material properties.

Purpose of the Study:

  • To report the construction of a multiple-reflection type ultra-small-angle X-ray scattering (USAXS) apparatus.
  • To enable the investigation of solute or particle distribution in turbid systems using USAXS.

Main Methods:

  • Construction of a multiple-reflection type ultra-small-angle X-ray scattering apparatus based on the Bonse-Hart principle.
  • Calibration of the USAXS apparatus using well-defined latex particles.

Main Results:
