Herman F. Mark
Herman Francis Mark (May 3, 1895, Vienna – April 6, 1992, Austin, Texas) was an Austrian-American chemist regarded for his contributions to the development of polymer science. Mark's x-ray diffraction work on the molecular structure of fibers provided important evidence for the macromolecule, macromolecular theory of polymer structure. Together with Houwink he formulated an equation, now called the Mark–Houwink equation, Mark–Houwink or Mark–Houwink–Sakurada equation, describing the dependence of the intrinsic viscosity of a polymer on its relative molecular mass (molecular weight). He was a long-time faculty at Polytechnic Institute of Brooklyn. In 1946, he established the ''Journal of Polymer Science''. Biography Early life ''Hermann Franz'' Mark was born in Vienna in 1895, the son of Hermann Carl Mark, a physician, and Lili Mueller. Mark's father was a Jew who converted to Christianity (Lutheran Church) upon marriage. Several early stimuli apparently steered Herman ...

Hawkesbury, Ontario
Hawkesbury is a Franco-Ontarian city in United Counties of Prescott and Russell, Prescott-Russell county in Eastern Ontario, Eastern Ontario, Canada. The vast majority of its 10,550 inhabitants are Francophone Canadians, francophone. The Long-Sault Bridge links it to Grenville-sur-la-Rouge, Quebec, Grenville, Quebec to the north. This bridge, crossing Chenail Island, is the only interprovincial bridge between Ontario and Quebec east of Ottawa. Hawkesbury is about halfway between Ottawa and Montréal. History Founded in 1798, Hawkesbury was named after Charles Jenkinson, 1st Earl of Liverpool, Charles Jenkinson, Baron Hawkesbury. Thomas Mears and David Pattee, two Americans, entered into a partnership in 1805, in order to harness the power of the lower Ottawa River and built the first sawmill on the Upper Canada side of the river. The town of Hawkesbury developed around this mill. Mears also built the Union, the Ottawa River's first steamer. Demand for timber during the Napoleon ...

Dresden
Dresden (, ; Upper Saxon: ''Dräsdn''; wen, label=Upper Sorbian, Drježdźany) is the capital city of the German state of Saxony and its second most populous city, after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area (after Berlin, Hamburg and Cologne), and the third most populous city in the area of former East Germany, after Berlin and Leipzig. Dresden's urban area comprises the towns of Freital, Pirna, Radebeul, Meissen, Coswig, Radeberg and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. Most of the city's population lives in the Elbe Valley, but a large, albeit very sparsely populated area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia. Many boroughs west of the Elbe lie in the foreland of the Ore Mounta ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Canadian International Pulp And Paper Company
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Synthetic Rubber
A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About 32-million metric tons of rubbers are produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, Seal (mechanical), seals such as O-rings and gaskets, hoses, Belt (mechanical), belts, Rubber mat, matting, and flooring. They offer a different range of physical and chemical properties, so can improve the reliability of a given product or application. Synthetic rubbers are superior to natural rubbers in two major respects, thermal stability and resistance to oils and related compounds. They are more resistant to oxidizing agents, such as oxygen and ozone which can reduce the life of products like tires. History of synthetic rubber The expanded use of bicycles, and particularly their pneumatic tires, starting in the 1890s, create ...

Polyvinyl Alcohol
Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula H2CH(OH)sub>''n''. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless. It is commonly supplied as beads or as solutions in water. Without an externally added crosslinking agent, PVA solution can be gelled through repeated freezing-thawing, yielding highly strong, ultrapure, biocompatible hydrogels which have been used for a variety of applications such as vascular stents, cartilages, contact lenses, etc. Uses PVA is used in a variety of medical applications because of its biocompatibility, low tendency for protein adhesion, and low toxicity. Specific uses include cartilage replacements, contact lenses, and eye drops. Polyvinyl alcohol is used as an aid in suspension polymerizations. Its largest appli ...

Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and in the jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. I ...

Kurt Meyer (chemist)
Kurt Meyer (23 December 1910 – 23 December 1961) was an SS commander and convicted war criminal of Nazi Germany. He served in the Waffen-SS (the combat branch of the SS) and participated in the Battle of France, Operation Barbarossa, and other engagements during World War II. Meyer commanded the 12th SS Panzer Division Hitlerjugend during the Allied invasion of Normandy, and was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves and Swords. After ordering the mass murder of civilians and prisoners of war (POWs) several times during the conflict, Meyer was convicted of war crimes for his role in the Ardenne Abbey massacre (the murder of Canadian POWs in Normandy). He was sentenced to death, but the sentence was later commuted to life in prison. He became active in HIAG, a lobby group organised by former high-ranking Waffen-SS men, after his release. Meyer was a leading Waffen-SS apologist and HIAG's most effective spokesperson, depicting most of the Waffen- ...
