Monument to the X-ray and Radium Martyrs of All Nations erected 1936 at St. Georg hospital in Hamburg, commemorating 359 early radiology workers. Wilhelm Röntgen discovered X-rays on November 8, 1895, and their use spread very quickly for medical diagnostics, particularly broken bones and embedded foreign objects where they were a ...
The Lada XRAY is a subcompact crossover SUV produced by the Russian car manufacturer AvtoVAZ. Designed by a team led by Steve Mattin, [2] the chief designer of the Lada Vesta, [3] it was first presented as a concept in August 2012 at the Moscow International Automobile Salon. A newer version, the Lada XRAY Concept 2, debuted in August 2014.
10 nm Shortest extreme ultraviolet wavelength or longest X-ray wavelength [72] 10 nm – the average length of a nanowire; 10 nm – lower size of tobacco smoke [73] 10 nm – the average half-pitch of a memory cell manufactured circa 2016 –2017; 13 nm – the length of the wavelength that is used for EUV lithography
X-ray absorption (left) and differential phase-contrast (right) image of an in-ear headphone obtained with a grating interferometer at 60kVp. Phase-contrast X-ray imaging or phase-sensitive X-ray imaging is a general term for different technical methods that use information concerning changes in the phase of an X-ray beam that passes through an object in order to create its images.
Mass attenuation coefficients of selected elements for X-ray photons with energies up to 250 keV. The mass attenuation coefficient, or mass narrow beam attenuation coefficient of a material is the attenuation coefficient normalized by the density of the material; that is, the attenuation per unit mass (rather than per unit of distance).
Series of density maps for GroEL: from left to right, 4 Å, 8 Å, 16 Å, and 32 Å resolution.The details are smeared away as the resolution becomes lower. Resolution in the context of structural biology is the ability to distinguish the presence or absence of atoms or groups of atoms in a biomolecular structure.
The detectors for observing cosmic X-ray sources were X-ray proportional counters. The hard X-ray telescope operated over the energy range 7 - 550 keV. OSO 7 performed an X-ray All-sky survey and discovered the 9-day periodicity in Vela X-1 which led to its optical identification as a HMXRB. OSO 7 was launched on September 29, 1971 and operated ...
