Small-angle x-ray scattering和xrd
WebbI was surprised to find out that the q-value in small angle X-ray scattering (SAXS) is not defined in the same way. Units are the same [1/nm] or [1/Angstrom], but there is a factor of 2pi in there. Small-angle X-ray scattering (SAXS) is a small-angle scattering technique by which nanoscale density differences in a sample can be quantified. This means that it can determine nanoparticle size distributions, resolve the size and shape of (monodisperse) macromolecules, determine pore sizes, … Visa mer SAXS is used for the determination of the microscale or nanoscale structure of particle systems in terms of such parameters as averaged particle sizes, shapes, distribution, and surface-to-volume ratio.
