Thermoplastic Polyurethane
Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments. Chemistry TPU is a block copolymer consisting of alternating sequences of hard and soft segments or domains formed by the reaction of (1) diisocyanates with short-chain diols (so-called chain extenders) and (2) diisocyanates with long-chain diols. By varying the ratio, structure and/or molecular weight of the reaction compounds, an enormous variety of different TPU can be produced. This allows urethane chemists to fine-tune the polymer's structure to the desired final properties of the material. Morphology A TPU resin consists of linear polymeric chains in block-structures. Such chains contain low polarity segments which are rather long (called soft segments), alternating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio Agricultural Research And Development Center
Ohio Agricultural Research and Development Center (OARDC) is the research institution of the Ohio State University College of Food, Agricultural, and Environmental Sciences. The center is home to research projects ranging from plant and animal sciences to human ecology and medicine, and includes branches across the state covering a total of over 7,000 acres (28 km²).

College Of Wooster
The College of Wooster is a private liberal arts college in Wooster, Ohio. Founded in 1866 by the Presbyterian Church as the University of Wooster, it has been officially non-sectarian since 1969 when ownership ties with the Presbyterian Church ended. From its creation, the college has been a co-educational institution. It enrolls about 2,000 students and is a member of The Five Colleges of Ohio, Great Lakes Colleges Association, and the Association of Presbyterian Colleges and Universities. History Founded as the University of Wooster in 1866 by Presbyterians, the institution opened its doors in 1870 with a faculty of five and a student body of thirty men and four women. Ephraim Quinby, a Wooster citizen, donated the first , a large oak grove situated on a hilltop overlooking the town. After being founded with the intent to make Wooster open to everyone, the university's first Ph.D. was granted to a woman, Annie B. Irish, in 1882. The first black student, Clarence Allen, beg ...

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 ...

Cornell University
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Education City, Qatar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio State University
The Ohio State University, commonly called Ohio State or OSU, is a public land-grant research university in Columbus, Ohio. A member of the University System of Ohio, it has been ranked by major institutional rankings among the best public universities in the United States. Founded in 1870 as the state's land-grant university and the ninth university in Ohio with the Morrill Act of 1862, Ohio State was originally known as the Ohio Agricultural and Mechanical College and focused on various agricultural and mechanical disciplines, but it developed into a comprehensive university under the direction of then-Governor and later U.S. president Rutherford B. Hayes, and in 1878, the Ohio General Assembly passed a law changing the name to "the Ohio State University" and broadening the scope of the university. Admission standards tightened and became greatly more selective throughout the 2000s and 2010s. Ohio State's political science department and faculty have greatly contri ...

Goodrich Corporation
The Goodrich Corporation, formerly the B.F. Goodrich Company, was an American manufacturing company based in Charlotte, North Carolina. Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Benjamin Goodrich, the company name was changed to the "B.F. Goodrich Company" in 1880, to BFGoodrich in the 1980s, and to "Goodrich Corporation" in 2001. Originally a rubber manufacturing company known for automobile tires, the company diversified its manufacturing businesses throughout the twentieth century and sold off its tire business in 1986 to focus on its other businesses, such as aerospace and chemical manufacturing. The BFGoodrich brand name continues to be used by Michelin, who acquired the tire manufacturing business in 1988. Following the acquisition by United Technologies in 2012, Goodrich became a part of UTC Aerospace Systems.

Waldo Semon
Waldo Lonsbury Semon (September 10, 1898 – May 26, 1999) was an American inventor born in Demopolis, Alabama. He is credited with inventing methods for making polyvinyl chloride useful. Biography He was born on September 10, 1898. Semon is best known for inventing vinyl, the world's third most used plastic. He is also credited for being the first to commercialise plasticizers for vinyl, which greatly increased their utility, starting with dibutyl phthalate. He found the formula for vinyl by mixing a few synthetic polymers, and the result was a substance that was elastic, but wasn't adhesive. Semon worked on methods of improving rubber, and eventually developed a synthetic substitute. On December 11, 1935, he created ''Koroseal'' from salt, coke and limestone, a polymer that could be made in any consistency. Semon made more than 5,000 other synthetic rubber compounds, achieving success with ''Ameripol'' (AMERican POLymer) in 1940 for the B.F. Goodrich company. In all, ...

Magnetic Tape
Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape could with relative ease record and playback audio, visual, and binary computer data. Magnetic tape revolutionized sound recording and reproduction and broadcasting. It allowed radio, which had always been broadcast live, to be recorded for later or repeated airing. Since the early 1950s, magnetic tape has been used with computers to store large quantities of data and is still used for backup purposes. Magnetic tape begins to degrade after 10–20 years and therefore is not an ideal medium for long-term archival storage. Durability While good for short-term use, magnetic tape is highly prone to disintegration. Depending on the environment, this process may begin after 10–20 years. Over time, magnetic tape made in the 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
