Albert Leon Henne
Albert Leon Henne (1901–1967) was an American chemist known for his work on refrigerants. Henne was born in Brussels, Belgium in 1901. He earned his PhD from the University of Brussels in 1925 with a dissertation titled "The Stereoisomers of Chloroiodoethylene". He came to the United States in 1925 as a fellow of the Belgian-American Education foundation at Massachusetts Institute of Technology and became a naturalized citizen in 1933. Henne's association with the Ohio State University Department of Chemistry began in 1931 when he began service as a Special Lecturer and as Director of Research for what was formally called the Midgley Foundation housed in the organic chemistry laboratories at OSU. He served in this capacity until 1938 when he was appointed associate professor of chemistry. He assisted Professor Cecil E. Boord in setting up and organizing the American Petroleum Institute Project at Ohio State. Henne was appointed Professor of Chemistry in 1942 and served in thi ...

Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of Chemistry#Subdisciplines, subdisciplines of chemistry. Materials science, Materials scientists and metallurgists sha ...

Free University Of Brussels (1834–1969)
The Free University of Brussels ( or ULB; , later ''Vrije Universiteit Brussel'') was a private university in Brussels, Belgium. It existed between 1834 and 1969 when it split along linguistic lines. Founded in 1834 on the principle of "free inquiry" (), its founders envisaged the institution as a freethought, freethinker reaction to the traditional dominance of Catholicism in the country's education system. It was avowedly secularism, secular and particularly associated with Liberalism in Belgium, political liberalism during the era of pillarisation. The Free University was one of Belgium's major universities, together with the Catholic University of Leuven (1835–1968), Catholic University of Leuven and the University of Liège, state universities of Liège and University of Ghent, Ghent. The "Linguistic Wars" affected the Free University, which split along language lines in 1969 in the aftermath of Split of the Catholic University of Leuven, student unrest at Leuven the prev ...

Massachusetts Institute Of Technology
The Massachusetts Institute of Technology (MIT) is a Private university, private research university in Cambridge, Massachusetts, United States. Established in 1861, MIT has played a significant role in the development of many areas of modern technology and science. In response to the increasing Technological and industrial history of the United States, industrialization of the United States, William Barton Rogers organized a school in Boston to create "useful knowledge." Initially funded by a land-grant universities, federal land grant, the institute adopted a Polytechnic, polytechnic model that stressed laboratory instruction in applied science and engineering. MIT moved from Boston to Cambridge in 1916 and grew rapidly through collaboration with private industry, military branches, and new federal basic research agencies, the formation of which was influenced by MIT faculty like Vannevar Bush. In the late twentieth century, MIT became a leading center for research in compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citizenship In The United States
Citizenship of the United States is a legal status that entails Americans with specific rights, duties, protections, and benefits in the United States. It serves as a foundation of fundamental rights derived from and protected by the Constitution and laws of the United States, such as freedom of expression, due process, the rights to vote, live and work in the United States, and to receive federal assistance. There are two primary sources of citizenship: birthright citizenship, in which persons born within the territorial limits of the United States (except American Samoa) are presumed to be a citizen, or—providing certain other requirements are met—born abroad to a United States citizen parent, and naturalization, a process in which an eligible legal immigrant applies for citizenship and is accepted. The first of these two pathways to citizenship is specified in the Citizenship Clause of the Fourteenth Amendment of the Constitution which reads: The second is provid ...

American Petroleum Institute
The American Petroleum Institute (API) is the largest U.S. trade association for the oil and natural gas industry. It claims to represent nearly 600 corporations involved in extraction of petroleum, production, oil refinery, refinement, pipeline transport, distribution, and many other aspects of the petroleum industry.

Freon
Freon ( ) is a registered trademark of the Chemours Company and generic descriptor for a number of halocarbon products. They are stable, nonflammable, low toxicity gases or liquids which have generally been used as refrigerants and as aerosol propellants. They include chlorofluorocarbons and hydrofluorocarbons, both of which cause ozone depletion (although the latter much less so) and contribute to global warming. 'Freon' is the brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company. They emit a strong smell similar to acetone. Freon has been found to cause damage to human health when inhaled in large amounts. Studies have been conducted in the pursuit to find beneficial reuses for gases under the Freon umbrella as an alternative to disposal of the gas. History The first CFCs were synthesized by Frédéric Swarts in the 1890s. In the late 1920s, a research team was formed by Charles Franklin Kettering in General ...

Refrigeration
Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature).IIR International Dictionary of Refrigeration, http://dictionary.iifiir.org/search.php ASHRAE Terminology, https://www.ashrae.org/technical-resources/free-resources/ashrae-terminology Refrigeration is an artificial, or human-made, cooling method. Refrigeration refers to the process by which energy, in the form of heat, is removed from a low-temperature medium and transferred to a high-temperature medium. This work of energy transfer is traditionally driven by work (physics), mechanical means (whether ice or electromechanics, electromechanical machines), but it can also be driven by heat, magnetism, electricity, laser cooling, laser, or other means. Refrigeration has many applications, including household refrigerators, industrial freezers, cryogenics, and air conditioni ...

Organofluorine Chemistry
Organofluorine chemistry describes the chemistry of organofluorine compounds, organic compounds that contain a carbon–fluorine bond. Organofluorine compounds find diverse applications ranging from Lipophobicity, oil and hydrophobe, water repellents to pharmaceuticals, refrigerants, and reagents in catalysis. In addition to these applications, some organofluorine compounds are pollutants because of their contributions to ozone depletion, global warming, bioaccumulation, and toxicity. The area of organofluorine chemistry often requires special techniques associated with the handling of fluorinating agents. The carbon–fluorine bond Fluorine has several distinctive differences from all other substituents encountered in organic molecules. As a result, the physical and chemical properties of organofluorines can be distinctive in comparison to other organohalogens. # The carbon–fluorine bond is one of the strongest in organic chemistry (an average bond energy around 480 kJ/mol). ...
