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.
The 9K38 Igla ( Russian: Игла́, "needle", NATO reporting name SA-18 Grouse) is a Soviet / Russian man-portable infrared homing surface-to-air missile (SAM) system. A simplified, earlier version is known as the 9K310 Igla-1 (NATO: SA-16 Gimlet ), and the latest variant is the 9K338 Igla-S ( SA-24 Grinch ). The Igla-1 entered service in 1981 ...
Universal Windows Platform. Fluent Design System. v. t. e. Windows 10 is a major release of Microsoft 's Windows NT operating system. It is the direct successor to Windows 8.1, which was released nearly two years earlier. It was released to manufacturing on July 15, 2015, and later to retail on July 29, 2015. [ 20]
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 ...
Microsoft shares fell 2.4% on Wednesday as growth in the tech giant's cloud business slowed, while Nvidia and other chipmakers rallied following a bright quarterly report from Advanced Micro Devices.
June 29, 2024 at 8:50 AM. MIAMI (AP) — As Donald Trump narrows his options for a potential running mate, two politicians known to be on his list are from Florida, leaving open a scenario where ...
President Joe Biden returns to the campaign trail Tuesday for the first time since the attempted assassination of his Republican rival, former President Donald Trump, aiming to sharpen the choice ...
X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist , or simply "resist," on the substrate to reach extremely small topological size of a feature.
