Maurice Brookhart
Maurice S. Brookhart (born 1942) is an American chemist, and professor of chemistry at the University of Houston since 2015. Brookhart received his bachelor's degree from Johns Hopkins University in 1964. He received his PhD in 1968 from the University of California, Los Angeles, in physical organic chemistry where his thesis advisor was Saul Winstein. After an NSF postdoctoral fellowship at the University of California, Los Angeles in 1968 and a NATO postdoctoral fellowship at Southampton University, England. In 1969, he joined the faculty of the University of North Carolina, where he stayed until 2015, when he joined the University of Houston as a professor of Chemistry. His research group is noted for its research in the general area of synthetic and mechanistic organometallic chemistry. A recent major thrust has been the development of post-metallocene catalysts based upon late transition metal (Ni and Pd) complexes for olefin coordination polymerization. They carry ...

Cumberland (Maryland)
Cumberland is a U.S. city in and the county seat of Allegany County, Maryland. It is the primary city of the Cumberland, MD-WV Metropolitan Statistical Area. At the 2020 census, the city had a population of 19,076. Located on the Potomac River, Cumberland is a regional business and commercial center for Western Maryland and the Potomac Highlands of West Virginia. Historically Cumberland was known as the "Queen City", as it was once the second largest in the state. Because of its strategic location on what became known as the Cumberland Road through the Appalachians, after the American Revolution it served as a historical outfitting and staging point for westward emigrant trail migrations throughout the first half of the 1800s. In this role, it supported the settlement of the Ohio Country and the lands in that latitude of the Louisiana Purchase. It also became an industrial center, served by major roads, railroads, and the Chesapeake and Ohio Canal, which connected Cumberland ...

University Of California, Los Angeles
The University of California, Los Angeles (UCLA) is a public university, public Land-grant university, land-grant research university in Los Angeles, California. UCLA's academic roots were established in 1881 as a Normal school, teachers college then known as the southern branch of the California State Normal School (now San Jose State University, San José State University). This school was absorbed with the official founding of UCLA as the Southern Branch of the University of California in 1919, making it the second-oldest of the 10-campus University of California system (after UC Berkeley). UCLA offers 337 undergraduate and graduate degree programs in a wide range of disciplines, enrolling about 31,600 undergraduate and 14,300 graduate and professional students. UCLA received 174,914 undergraduate applications for Fall 2022, including transfers, making the school the most applied-to Higher education in the United States, university in the United States.

21st-century American Chemists
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman ...

University Of North Carolina At Chapel Hill Faculty
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, Hilde ...

United States 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 ...

Coordination Polymerization
Coordination polymerisation is a form of polymerization that is catalyzed by transition metal salts and complexes. Types of coordination polymerization of alkenes Heterogeneous Ziegler–Natta polymerization Coordination polymerization started in the 1950s with heterogeneous Ziegler–Natta catalysts based on titanium tetrachloride and organoaluminium co-catalysts. The mixing of TiCl4 with trialkylaluminium complexes produces Ti(III)-containing solids that catalyze the polymerization of ethene and propene. The nature of the catalytic center has been of intense interest but remains uncertain. Many additives and variations have been reported for the original recipes. Homogeneous Ziegler–Natta polymerization In some applications heterogeneous Ziegler–Natta polymerization has been superseded by homogeneous catalysts such as the Kaminsky catalyst discovered in the 1970s. The 1990s brought forward a new range of post-metallocene catalysts. Typical monomers are nonpolar ethene and pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-metallocene Catalyst
A post-metallocene catalyst is a kind of catalyst for the polymerization of olefins, i.e., the industrial production of some of the most common plastics. "Post-metallocene" refers to a class of homogeneous catalysts that are not metallocenes. This area has attracted much attention because the market for polyethylene, polypropylene, and related copolymers is large. There is a corresponding intense market for new processes as indicated by the fact that, in the US alone, 50,000 patents were issued between 1991-2007 on polyethylene and polypropylene. Many methods exist to polymerize alkenes, including the traditional routes using Philips catalyst and traditional heterogeneous Ziegler-Natta catalysts, which still are used to produce the bulk of polyethylene.
