Particle-Induced X-Ray Emission or Proton-Induced X-Ray Emission (PIXE) is a technique used for determining the elemental composition of a material or a sample.When a material is exposed to an ion beam, atomic interactions occur that give off EM radiation of wavelengths in the x-ray part of the electromagnetic spectrum specific to an element.
Robert George Jahn (April 1, 1930 – November 15, 2017) was an American plasma physicist, Professor of Aerospace Science, and Dean of Engineering at Princeton University. [1] Jahn was also a founder of the Princeton Engineering Anomalies Research Lab (PEAR), a parapsychology research program which ran from 1979 to 2007.

While WDS is slower than EDS and more sensitive to the positioning of the sample in the spectrometer, it has superior spectral resolution and sensitivity. WDS is widely used in microprobes (where X-ray microanalysis is the main task) and in XRF; it is widely used in the field of X-ray diffraction to calculate various data such as interplanar ...
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science.Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.

Aaron Rodgers now has one NFL record of Tom Brady’s that the seven-time Super Bowl champ is probably very okay with losing: the most-sacked quarterback in NFL history.. But Rodgers, 41 ...
A year after a panel blew out of a Boeing 737 Max during flight, the nation’s top aviation regulator says the company needs "a fundamental cultural shift” to put safety and quality above profits.
