At the time of the Miller–Urey experiment, Harold Urey was a Professor of Chemistry at the University of Chicago who had a well-renowned career, including receiving the Nobel Prize in Chemistry in 1934 for his isolation of deuterium [21] and leading efforts to use gaseous diffusion for uranium isotope enrichment in support of the Manhattan Project. [22] In 1952, Urey postulated that the high ...
Argonne National Laboratory is a federally funded research and development center in Lemont, Illinois, United States. Founded in 1946, the laboratory is owned by the United States Department of Energy and administered by UChicago Argonne LLC of the University of Chicago. [2][3] The facility is the largest national laboratory in the Midwest.
Steven Simon (University of Chicago) and seven colleagues from the University of Chicago, the Planetary Studies Foundation, Harper College, Pacific Northwest National Lab, and the Field Museum of Natural History have classified the meteorite fragments that fell on Chicago 's southern suburbs on the night of March 26, 2003. That area is described as "the most densely populated region to be hit ...
The first unambiguous consequence of the existence of presolar grains within meteorites came from the laboratory of Edward Anders in Chicago, [11] who found using traditional mass spectrometry that the xenon isotopic abundances contained within an acid-insoluble carbonaceous residue that remained after the meteorite bulk had been dissolved in ...
The High-frequency Active Auroral Research Program (HAARP) is a University of Alaska Fairbanks program which researches the ionosphere – the highest, ionized part of Earth's atmosphere. Work on the HAARP facility began in 1993. The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power radio frequency ...
Widmanstätten patterns, also known as Thomson structures, are figures of long phases of nickel – iron, found in the octahedrite shapes of iron meteorite crystals and some pallasites. Iron meteorites are very often formed from a single crystal of iron-nickel alloy, or sometimes a number of large crystals that may be many meters in size, and ...
Specifically, the company took material from a meteorite that landed in Argentina in prehistoric times, processed it and fed it through the new 3D Systems ProX DMP 320 direct metal printer. The ...
He moved to the University of Chicago at the Enrico Fermi Institute for Nuclear Studies (1977-1980) where he worked with Robert N. Clayton using lunar samples to track solar wind origin and evolution, meteorite cosmochemistry, and early atmospheric chemistry.
