Owen Webster
Owen Wright Webster (March 25, 1929 – April 13, 2018) was a distinguished member of the organic and polymer chemistry communities. His polymerization technique for making block copolymer dispersing agents is used by DuPont to make ink-jet printer inks. Born in Devils Lake, North Dakota, Webster received a Bachelor of Science degree from the University of North Dakota in 1951. He received his Ph.D. in organic chemistry from Pennsylvania State University in 1955 under the direction of L. H. Sommer, known for his silicon mechanistic work. After graduation, Webster joined the Central Research Department of E. I. du Pont de Nemours and Company at the DuPont Experimental Station, Experimental Station, where he spent his entire industrial career. He is Adjunct Professor of Chemistry at both the University of Alabama and the University of Pennsylvania. Webster’s early research activities at du Pont involved synthesis of cyanocarbons. His seminal discoveries in this area ranged fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glen Mills, Pennsylvania
Glen Mills is an unincorporated community in Concord Township, Delaware County, Pennsylvania, United States about 27 miles west of Philadelphia. The ZIP code for Glen Mills is 19342. History The area around Glen Mills was part of the original land grant given to William Penn in 1681. George Cheyney was the first settler here, for which the nearby town of Cheyney is named. Later, this land was sold and divided. The name Glen Mills is taken from two paper mills built by the Willcox family, one in 1835 and the second in 1846. From 1864 to 1878, these mills supplied the United States government with a special, patented paper for the printing of government bonds and notes. The Glen Mills are no longer standing, but the grist mill built by Nathaniel Newlin in 1704 still stands and is a popular destination for picnickers and history buffs alike. A blacksmith shop was built on the former property in 1975. The Newlin Mill Complex was listed on the National Register of Historic Places ...

Carbene
In organic chemistry, a carbene is a molecule containing a neutral carbon atom with a valence of two and two unshared valence electrons. The general formula is or where the R represents substituents or hydrogen atoms. The term "carbene" may also refer to the specific compound , also called methylene, the parent hydride from which all other carbene compounds are formally derived. Carbenes are classified as either singlets or triplets, depending upon their electronic structure. Most carbenes are very short lived, although persistent carbenes are known. One well-studied carbene is dichlorocarbene , which can be generated ''in situ'' from chloroform and a strong base. Structures and bonding The two classes of carbenes are singlet and triplet carbenes. Singlet carbenes are spin-paired. In the language of valence bond theory, the molecule adopts an sp2 hybrid structure. Triplet carbenes have two unpaired electrons. Most carbenes have a nonlinear triplet ground state, e ...

People From Devils Lake, North Dakota
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Ink-jet
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals. The concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s. While working at Canon in Japan, Ichiro Endo suggested the idea for a "Bubble jet" printer, while around the same time Jon Vaught at HP was developing a similar idea. In the late 1970s, inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard (HP) and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Epson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrylic Polymer
An acrylate polymer (also known as acrylic or polyacrylate) is any of a group of polymers prepared from acrylate monomers. These plastics are noted for their transparency, resistance to breakage, and elasticity. Acrylate polymer is commonly used in cosmetics, such as nail polish, as an adhesive. History The first synthesis of acrylic polymer was reported by G.W.A Kahlbaum in 1880. Acrylic elastomers Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkylester (ethyl or butyl ester). Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C. It is used primarily for producing oil seals and packaging related to automobiles. Acrylic elastomer can generally be characterized as one of two types. "Old" types include ACM (copolymer of acrylic acid ester and 2-chloroethyl vinyl ether) containing chlorine and ANM (copolymer of acrylic acid ester and ...
