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.
X-ray reflectivity (sometimes known as X-ray specular reflectivity, X-ray reflectometry, or XRR) is a surface-sensitive analytical technique used in chemistry, physics, and materials science to characterize surfaces, thin films and multilayers.
New details are emerging about the case against Luigi Mangione, the man indicted on murder charges in the deadly shooting of UnitedHealthcare CEO Brian Thompson in New York City. The 26-year-old ...
Clark went on to win Rookie of the Year, averaging 19.2 points, a league-high 8.4 assists and 5.7 rebounds per game. She led the Fever to their best record (20-20) and first playoff appearance ...
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
With their fourth consecutive win, the Cavaliers improved to 21-3, 1.5 games ahead of the Boston Celtics (19-4) for the NBA's top record. Mobley's previous career best was 38, set in January 2023 ...
Iron-55 decays via electron capture to manganese-55 with a half-life of 2.737 years. [1] The electrons around the nucleus rapidly adjust themselves to the lowered charge without leaving their shell, and shortly thereafter the vacancy in the "K" shell left by the nuclear-captured electron is filled by an electron from a higher shell.
