Donald J. Cram
Donald James Cram (April 22, 1919 – June 17, 2001) was an American chemist who shared the 1987 Nobel Prize in Chemistry with Jean-Marie Lehn and Charles J. Pedersen "for their development and use of molecules with structure-specific interactions of high selectivity." They were the founders of the field of host–guest chemistry. Early life Cram was born and raised in Chester, Vermont, to a Scottish immigrant father, and a German immigrant mother. His father died before Cram turned four, leaving him the only male in a family of five. He grew up on Aid to Dependent Children, and learned to work at an early age, doing jobs such as picking fruit, tossing newspapers, and painting houses, while bartering for piano lessons. By the time he turned eighteen, he had worked at least eighteen different jobs. Cram attended the Winwood High School in Long Island, N.Y. From 1938 to 1941, he attended Rollins College, in Winter Park, Florida on a national honorary scholarship, where he w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chester, Vermont
Chester is a town in Windsor County, Vermont, United States. The population was 3,005 at the 2020 census. History The town was originally chartered by New Hampshire Governor Benning Wentworth as Flamstead in 1754. The terms of the charter were not met and the town was re-chartered as New Flamstead in 1761. In 1766, a patent was issued by New York that changed the name of the town to Chester, after George Augustus Frederick, the Earl of Chester and the eldest son of King George III. Later, the governing authority of Chester reverted to the 1761 charter by an act of the Vermont legislature, although it left the name "Chester" in place. 2011 was thus the 250th anniversary of the town. Geography According to the United States Census Bureau, the town has a total area of , of which is land and , or 0.46%, is water. A prominent geological feature of the town is the Williams River, a tributary of the Connecticut River, whose three branches come together as a central river and run thr ...

Organic Chemistry
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.Clayden, J.; Greeves, N. and Warren, S. (2012) ''Organic Chemistry''. Oxford University Press. pp. 1–15. . Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical ( in silico) study. The range of chemicals studied in organic chemistry includes hydrocarbons (compounds containing only carbon and hydrogen) as well as compounds based on carbon, but also containing other elements, especially oxygen, nitrogen, sulfur, phosphorus (included in ...

Master Of Science
A Master of Science ( la, Magisterii Scientiae; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree in the field of science awarded by universities in many countries or a person holding such a degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis. The Master of Science degree was first introduced at the University of Michigan in 1858. One of the first recipients of the degree was De Volson Wood, who was conferred a Master of Science degree at the University of Michigan in 1859. Al ...

University Of Nebraska–Lincoln
The University of Nebraska–Lincoln (Nebraska, NU, or UNL) is a public land-grant research university in Lincoln, Nebraska. Chartered in 1869 by the Nebraska Legislature as part of the Morrill Act of 1862, the school was known as the University of Nebraska until 1968, when it absorbed the Municipal University of Omaha to form the University of Nebraska system. It is the state's oldest university and the flagship institution of the state-wide system. The university has been governed by the Board of Regents since 1871, whose members are elected by district to six-year terms. The university is organized into nine colleges: Agricultural Sciences and Natural Resources, Architecture, Arts and Sciences, Business, Education and Human Sciences, Engineering, Fine and Performing Arts, Journalism and Mass Communications, and Law. NU offers over two hundred degrees across its undergraduate, graduate, and doctoral programs. The school also offers programs through the University of Nebr ...

Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambda Chi Alpha

Aid To Dependent Children
Aid to Families with Dependent Children (AFDC) was a federal assistance program in the United States in effect from 1935 to 1997, created by the Social Security Act (SSA) and administered by the United States Department of Health and Human Services that provided financial assistance to children whose families had low or no income. The program grew from a minor part of the social security system to a significant system of welfare administered by the states with federal funding. However, it was criticized for offering incentives for women to have children, and for providing disincentives for women to join the workforce. In July 1997, AFDC was replaced by the more restrictive Temporary Assistance for Needy Families (TANF) program. History The program was created under the name Aid to Dependent Children (ADC) by the Social Security Act of 1935 as part of the New Deal. It was created as a means tested entitlement which subsidized the income of families where fathers were "de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Host–guest Chemistry
In supramolecular chemistry, host–guest chemistry describes complexes that are composed of two or more molecules or ions that are held together in unique structural relationships by forces other than those of full covalent bonds. Host–guest chemistry encompasses the idea of molecular recognition and interactions through non-covalent bonding. Non-covalent bonding is critical in maintaining the 3D structure of large molecules, such as proteins and is involved in many biological processes in which large molecules bind specifically but transiently to one another. Although non-covalent interactions could be roughly divided into those with more electrostatic or dispersive contributions, there are few commonly mentioned types of non-covalent interactions: ionic bonding, hydrogen bonding, van der Waals forces and hydrophobic interactions. Overview Host–guest chemistry is a branch of supramolecular chemistry in which a host molecule forms a chemical compound with a guest molecul ...

Charles J
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...
