X-ray absorption spectroscopy. X-ray absorption spectroscopy (XAS) is a widely used technique for determining the local geometric and/or electronic structure of matter. [1] The experiment is usually performed at synchrotron radiation facilities, which provide intense and tunable X-ray beams. Samples can be in the gas phase, solutions, or solids.
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, characteristic distances of partially ordered materials, and much more.
Industrial radiography is a modality of non-destructive testing that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures. It plays an important role in the science and technology needed ...
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 ...
June 4, 2024 at 3:16 PM. NEW YORK (AP) — Donald Trump’s lawyers are asking a New York judge to lift the gag order that barred the former president from commenting about witnesses, jurors and ...
U.S. Immigration and Customs Enforcement (ICE) will close a costly Texas detention center and reallocate the funds to increase overall detention capacity as the agency ramps up operations to ...
That’s because the batboy at the Dodgers’ 4-0 over the White Sox on Wednesday saved star Shohei Ohtani from a potential injury in the Los Angeles dugout. At one point in the game, the Dodgers ...
Wide-angle X-ray scattering. In X-ray crystallography, wide-angle X-ray scattering ( WAXS) or wide-angle X-ray diffraction ( WAXD) is the analysis of Bragg peaks scattered to wide angles, which (by Bragg's law) are caused by sub-nanometer-sized structures. [1] It is an X-ray-diffraction [2] method and commonly used to determine a range of ...
