![]() The name under this image reads “Body-centered cubic. Consequently, a family of planes produces a diffraction peak only at a specific angle 2. using the Powder Cell 2.4 full-profile analysis program. In most diffractometers, the X-ray wavelength is fixed. properties of NiO nanoparticles were studied by XRD, TEM, FTIR, UV-VIS, and VSM. The name under this image reads “Simple cubic.” The second image in the top row shows a cube with black dots at each corner and a red dot in the center while the second image in the second row is composed of eight spheres that are stacked together to form a cube with one sphere in the center of the cube and dots at the center of each corner sphere connected to form a cube shape. from X-rays scattered by parallel planes of atoms will produce a diffraction peak. The first three images are in a row and are labeled “Lattice point locations” while the second three images are in a row labeled “Cubic unit cells.” The first image in the top row shows a cube with black dots at each corner while the first image in the second row is composed of eight spheres that are stacked together to form a cube and dots at the center of each sphere are connected to form a cube shape. 2012 was the 100th Anniversary of X-Ray Diffraction X-rays were discovered by WC Rontgen in 1895 In 1912, PP Ewald developed a formula to describe the passage of light waves through an ordered array of scattering atoms, based on the hypothesis that crystals were composed of a space-lattice-like construction of particles. \): Cubic unit cells of metals show (in the upper figures) the locations of lattice points and (in the lower figures) metal atoms located in the unit cell. ![]()
