Energy-Dispersive X-Ray Emission Spectroscopy A review is given of recent developments in energy-dispersive x-ray emission spectroscopy, with the aim of providing both an introductory and usefully prac... RS Frankel,DW Aitken - 《Applied Spectroscopy》 被引量: 48发表: 1970年 Energy-Dispersive X...
Dual-energy X-ray absorptiometry (DXA) is an accurate and reliable method for assessing body composition, and is capable of separating body mass into LM and FM [10]. Moreover, DXA has the ability to measure on both a regional and whole-body basis with the advantages of low cost, low ra...
Surface applicator calibration and commissioning of an electronic brachytherapy system for nonmelanoma skin cancer treatment. The Xoft Axxent x-ray source has been used for treating nonmelanoma skin cancer since the surface applicators became clinically available in 2009. The auth... Yi,Rong,James,.....
A millihertz frequency X-ray quasi-periodic oscillation has been observed near the innermost orbit of an actively accreting supermassive black hole and its frequency has evolved significantly over 2 years, a phenomenon that is difficult to explain with existing models. ...
3.5 Electron dispersive X-ray spectroscopy Energy-dispersive X-ray spectroscopy is an X-ray technique employed to identify the elemental composition of materials. The data produced after EDX analysis in the form of spectra showing peaks that correspond to the elements making the composition of the ...
A proposal for an X-ray free-electron laser oscillator with an energy-recovery linac. We show that a free-electron laser oscillator generating x rays with wavelengths of about 1 A is feasible using ultralow emittance electron beams of a mult... KJ Kim,Y Shvyd'Ko,S Reiche - 《Physical ...
of X-rays and the (ER)X-ray detector comprising an annular slit which defines an incident beam of polychromatic X-rays to irradiate a portion of the analysis zone, (v) a scatter collimator disposed between the primary beam collimator and the ERX-ray detector, the scatter collimator comprising...
The study of the speciation of highly diluted elements by X-ray absorption spectroscopy (XAS) is extremely challenging, especially in environmental biogeochemistry sciences. Here we present an innovative synchrotron spectroscopy technique: high-energy resolution fluorescence detected XAS (HERFD-XAS). With ...
In addition, IHEP is taking the lead to push forward an international cooperation space science plan to explore the extreme universe (EXU). Cosmic-ray physics and high energy gamma-ray astronomy are also the main scientific objectives of the program, said Zhang. ...
Understanding the origin of lithium dendrite branching in Li6.5La3Zr1.5Ta0.5O12solid-state electrolyte via microscopy measurements Lithium dendrite growth in solid-state electrolytes is a significant challenge for next-generation battery development. Here, authors used dark-field X-ray microscopy to inv...
