(Nanowerk News) How can the component elements of an unknown material, such as a meteorite, be determined? X-ray fluorescence analysis can be used to identify an abundance of elements, by irradiating ...

X‐ray fluorescence (XRF) analysis has emerged as a transformative methodology for in‐situ elemental determination in soils. This technique offers a rapid, non‐destructive and cost‐effective means to ...

The formation of geological samples is the result of the constant depositing of inorganic and organic materials over millions of years. As layers of deposit accumulate, the increasing weight creates ...

The copper target was operated at voltages of 11 kV, 12 kV, 13 kV, and 14 kV for the electron source, and a 50 kV configuration using a molybdenum target was used as a representative example for the ...

Trace elements or metal elements are minerals found in trace levels in biological tissues. Some are confirmed to be nutritionally important, while the remaining are deemed non-essential. While trace ...

Flow-assisted corrosion, also termed flow-accelerated corrosion or FAC, has long been a common problem for nuclear and fossil fuel power plants in which steel piping and its components are degraded ...

WASHINGTON — Researchers have developed a new, focus-free technique for creating chemical maps using x-ray fluorescence. The approach offers fast, high-resolution measurements, which could be useful ...

The IAEA Technical Cooperation Program has implemented Regional Projects aiming at identifying the major sources of air pollution and their inventories, as well as the transboundary transport of ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...

Researchers studying the remains of six individuals from Pompeii concluded they asphyxiated during the volcanic eruption that doomed the town nearly 2,000 years ago. The research team used portable ...
