John Yates (chemist)
John T. Yates Jr. (August 3, 1935 – September 2015) was an American chemist. He was an investigator in the field of surface chemistry and physics, including both the structure and spectroscopy of atoms and molecules on surfaces, the dynamics of surface processes and the development of new methods for research in surface chemistry. He worked at the National Bureau of Standards (now NIST) in Washington, D.C., and subsequently at the University of Pittsburgh, where he was for 25 years the R. K. Mellon Professor of Chemistry and Physics as well as the founding director of the Pittsburgh Surface Science Center before moving to the University of Virginia in 2007. Yates received his bachelor's degree from Juniata College in 1956 and his doctorate in physical chemistry from the Massachusetts Institute of Technology in 1960. He was a Senior Visiting Scholar at the University of East Anglia from 1970 to 1971. Following three years as an assistant professor at Antioch College, he joined t ...

Winchester, Virginia
Winchester is the most north western independent city in the Commonwealth of Virginia. It is the county seat of Frederick County, although the two are separate jurisdictions. The Bureau of Economic Analysis combines the city of Winchester with surrounding Frederick County for statistical purposes. As of the 2020 census, the city's population was 28,120. Winchester is the principal city of the Winchester, Virginia–West Virginia, metropolitan statistical area, which is a part of the Baltimore–Washington metropolitan area. Winchester is home to Shenandoah University and the Museum of the Shenandoah Valley. History Native Americans Indigenous peoples lived along the waterways of present-day Virginia for thousands of years before European contact. Archeological, linguistic and anthropological studies have provided insights into their cultures. Though little is known of specific tribal movements before European contact, the Shenandoah Valley area, considered a sacred co ...

Spectroscopy
Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure an ...

University Of Pittsburgh Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hild ...

National Academy Of Sciences
The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve '' pro bono'' as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. ... to provide sci ...

Surface Chemistry
Surface science is the study of physical and chemical phenomena that occur at the interface of two phases, including solid–liquid interfaces, solid– gas interfaces, solid–vacuum interfaces, and liquid– gas interfaces. It includes the fields of '' surface chemistry'' and '' surface physics''. Some related practical applications are classed as surface engineering. The science encompasses concepts such as heterogeneous catalysis, semiconductor device fabrication, fuel cells, self-assembled monolayers, and adhesives. Surface science is closely related to interface and colloid science. Interfacial chemistry and physics are common subjects for both. The methods are different. In addition, interface and colloid science studies macroscopic phenomena that occur in heterogeneous systems due to peculiarities of interfaces. History The field of surface chemistry started with heterogeneous catalysis pioneered by Paul Sabatier on hydrogenation and Fritz Haber on the Haber proce ...

Free Union, Virginia
Free Union is a census-designated place (CDP) in Albemarle County, Virginia, United States, ten miles north-northwest of Charlottesville. The population as of the 2020 Census was 187. It is a very small hamlet consisting of a private school (Free Union Country School), a doctor's office, a post office, a country store, a homebuilder, and several dozen homes. Otherwise it is entirely rural in character. History The area was first settled in the mid-18th century and became a part of Albemarle County in 1761. The village was originally referred to as Nicksville after a free slave blacksmith named Nick, who opened a blacksmith's shop there in the early 19th century. When a post office was established in 1847, it was given the name of Free Union to avoid confusion with Nixville, another post office in the county. The name was taken from that of the Free Union Church, which had been built in 1837 and is still operating as the Free Union Baptist Church. The church was "free" in that all ...
