Jean'ne Shreeve
Jean'ne Marie Shreeve (born 1933) is an American chemist known for her studies of fluorine compounds and explosives. She has held her namesake professorship at the University of Idaho since 2004. Early life and education Born in Deer Lodge, Montana in 1933, Jean'ne Shreeve was the second of two children to Mary-Frances and Charles W. Shreeve. She was named for the popular 1928 song " Jeannine, I Dream of Lilac Time". Her father worked for the Northern Pacific Railway and her mother was a teacher, though she spent much of Jean'ne's childhood unemployed, her job a casualty of the Great Depression and the idea that families only needed one adult breadwinner. Mary-Frances later worked as a public school teacher for 40 years. Jean'ne Shreeve had a close bond with her brother William, 22 months older. She attended public schools in Montana for her primary and secondary education, graduating from Thompson Falls High School and earning a full scholarship to what was then Montana State ...

Fluorine
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative reactive element, it is extremely reactive, as it reacts with all other elements except for the light inert gases. Among the elements, fluorine ranks 24th in universal abundance and 13th in terrestrial abundance. Fluorite, the primary mineral source of fluorine which gave the element its name, was first described in 1529; as it was added to metal ores to lower their melting points for smelting, the Latin verb meaning 'flow' gave the mineral its name. Proposed as an element in 1810, fluorine proved difficult and dangerous to separate from its compounds, and several early experimenters died or sustained injuries from their attempts. Only in 1886 did French chemist Henri Moissan isolate elemental fluorine using low-temperature electrolysis, a process still employed for modern ...

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 em ...

Royal Society Of Chemistry
The Royal Society of Chemistry (RSC) is a learned society (professional association) in the United Kingdom with the goal of "advancing the chemical sciences". It was formed in 1980 from the amalgamation of the Chemical Society, the Royal Institute of Chemistry, the Faraday Society, and the Society for Analytical Chemistry with a new Royal Charter and the dual role of learned society and professional body. At its inception, the Society had a combined membership of 34,000 in the UK and a further 8,000 abroad. The headquarters of the Society are at Burlington House, Piccadilly, London. It also has offices in Thomas Graham House in Cambridge (named after Thomas Graham, the first president of the Chemical Society) where ''RSC Publishing'' is based. The Society has offices in the United States, on the campuses of The University of Pennsylvania and Drexel University, at the University City Science Center in Philadelphia, Pennsylvania, in both Beijing and Shanghai, China and in Ba ...

Iota Sigma Pi
Iota Sigma Pi () is a national honor society in the United States. It was established in 1902 and specializes in the promotion of women in the sciences, especially chemistry. It also focuses on personal and professional growth for women in these fields. As with all honor societies, they create professional networks along with recognizing achievements of women in chemistry. History The society was formed during a period when women gained little recognition for their work. Therefore, women began to set up their own awards to highlight their abilities on their resumes. The national society was formed in 1902 by Agnes Faye Morgan. She was appointed department chair of the Department of Household Science and Arts at the University of California and was one of the first to integrate chemistry into the curriculum of home economics. She continued to participate in the society throughout her professional life and had a particular focus on research. She also founded a local honour socie ...

Garvan–Olin Medal
The Francis P. Garvan–John M. Olin Medal is an annual award that recognizes distinguished scientific accomplishment, leadership and service to chemistry by women chemists. The Award is offered by the American Chemical Society (ACS), and consists of a cash prize (US$5,000) and a medal. The medal was designed by Margaret Christian Grigor. Background Any individual may nominate a single eligible chemist in one year. Nominees must be a female citizen of the United States. The award was established by Francis Garvan and Mabel Brady Garvan in 1936 in honor of their daughter. It was initially an essay contest, that ran for seven years, as a memorial to their daughter (the American Chemical Society's Prize Essay Contest). It was solely funded by the Francis P. Garvan Medal Endowment from its establishment in 1936 until 1979. W. R. Grace & Co. assumed co-sponsorship of the award from 1979 to 1983. In 1984, Olin Corporation assumed co-sponsorship.

Sloan Fellowship
The Sloan Research Fellowships are awarded annually by the Alfred P. Sloan Foundation since 1955 to "provide support and recognition to early-career scientists and scholars". This program is one of the oldest of its kind in the United States. Fellowships were initially awarded in physics, chemistry, and mathematics. Awards were later added in neuroscience (1972), economics (1980), computer science (1993), computational and evolutionary molecular biology (2002), and ocean sciences or earth systems sciences (2012). Winners of these two-year fellowships are awarded $75,000, which may be spent on any expense supporting their research.

Dinitrogen Difluoride
Dinitrogen difluoride is a chemical compound with the formula N2F2. It is a gas at room temperature, and was first identified in 1952 as the thermal decomposition product of the azide N3F. It has the structure F−N=N−F and exists in both a ''cis''- and ''trans''-form. Isomers The ''cis'' configuration lies in a C2v symmetry and the ''trans''-form has a symmetry of C2h. These isomers are thermally interconvertible but can be separated by low temperature fractionation. The ''trans''-form is less thermodynamically stable but can be stored in glass vessels. The ''cis''-form attacks glass over a time scale of about 2 weeks to form silicon tetrafluoride and nitrous oxide: :2 N2F2 + SiO2 → SiF4 + 2 N2O Preparation Most preparations of dinitrogen difluoride give mixtures of the two isomers, but they can be prepared independently. An aqueous method involves ''N'',''N''-difluorourea with concentrated potassium hydroxide. This gives a 40% yield with three times more ...
