   en.wikipedia.org/wiki/X-ray_scattering_techniques

   X-ray reflectivity is an analytical technique for determining thickness, roughness, and density of single layer and multilayer thin films. Wide-angle X-ray scattering (WAXS), a technique concentrating on scattering angles 2θ larger than 5°. Spectrum of various inelastic scattering processes that can be probed with inelastic X-ray scattering ...

4. Radiology - Wikipedia

   en.wikipedia.org/wiki/Radiology

   A radiologist interpreting magnetic resonance imaging. Dr. Macintyre's X-Ray Film (1896) Radiology ( / ˌreɪdɪˈɒlədʒi / rey-dee-ol-uh-jee) is the medical specialty that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a ...

5. X-ray crystallography - Wikipedia

   en.wikipedia.org/wiki/X-ray_crystallography

   A powder X-ray diffractometer in motion. X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer ...

6. X-ray photoelectron spectroscopy - Wikipedia

   en.wikipedia.org/wiki/X-ray_photoelectron...

   X-ray photoelectron spectroscopy ( XPS) is a surface-sensitive quantitative spectroscopic technique based on the photoelectric effect that can identify the elements that exist within a material (elemental composition) or are covering its surface, as well as their chemical state, and the overall electronic structure and density of the electronic ...

8. Radiochemistry - Wikipedia

   en.wikipedia.org/wiki/Radiochemistry

   Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable ).

9. Electromagnetic spectrum - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_spectrum

   The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and ...
