Katharine Burr Blodgett
Katharine Burr Blodgett (January 10, 1898 – October 12, 1979) was an American physicist and chemist known for her work on surface chemistry, in particular her invention of "invisible" or nonreflective glass while working at General Electric. She was the first woman to be awarded a PhD in physics from the University of Cambridge, in 1926. Early life Blodgett was born on January 10, 1898, in Schenectady, New York. She was the second child of Katharine Buchanan (Burr) and George Reddington Blodgett. Her father was a patent attorney at General Electric where he headed that department. He was shot and killed in his home by a burglar just before she was born. GE offered a $5,000 reward for the arrest and conviction of the killer, but the suspected killer hanged himself in his jail cell in Salem, New York. Her mother was financially secure after her husband's death, and she moved to New York City with Katharine and her son George Jr. shortly after Katharine's birth. In 1901, Kathari ...

Schenectady, New York
Schenectady () is a city in Schenectady County, New York, United States, of which it is the county seat. As of the 2020 census, the city's population of 67,047 made it the state's ninth-largest city by population. The city is in eastern New York, near the confluence of the Mohawk and Hudson rivers. It is in the same metropolitan area as the state capital, Albany, which is about southeast. Schenectady was founded on the south side of the Mohawk River by Dutch colonists in the 17th century, many of whom came from the Albany area. The name "Schenectady" is derived from the Mohawk word ''skahnéhtati'', meaning "beyond the pines" and used for the area around Albany, New York. Residents of the new village developed farms on strip plots along the river. Connected to the west by the Mohawk River and Erie Canal, Schenectady developed rapidly in the 19th century as part of the Mohawk Valley trade, manufacturing, and transportation corridor. By 1824, more people worked in manufac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salem, New York
Salem is a town in eastern Washington County, New York, United States. It is part of the Glens Falls Metropolitan Statistical Area. The town population was 2,702 at the 2000 census. The town of Salem contains a hamlet also named Salem, formerly an incorporated village. History Salem was first settled in 1761 by Joshua Conkey and James Turner, who as soldiers in the French and Indian War, passed through the territory. In 1764, Alexander and James Turner acquired a patent which was soon divided up between the New Englanders from Pelham, Massachusetts and a group of Scotch-Irish Presbyterians, led by Dr Thomas Clark from Ballybay, County Monaghan, Ireland. The Charlotte County and White Creek militia used Salem as its base in 1776. The 123rd Volunteer Regiment was recruited from Salem during the Civil War. The Alexander McNish House was added to the National Register of Historic Places in 2010 and Martin–Fitch House and Asa Fitch Jr. Laboratory in 2014. People of note i ...

Boston Marriage
A "Boston marriage" was, historically, the cohabitation of two wealthy women, independent of financial support from a man. The term is said to have been in use in New England in the late 19th/early 20th century. Some of these relationships were romantic in nature and might now be considered a lesbian relationship; others were not. Etymology The fact of relatively formalized romantic friendships or life partnerships between women predates the term ''Boston marriage'' and there is a long record of it in England and other European countries.Elizabeth Mavor, ''The Ladies of Llangollen'' (London: Penguin, 1971) The term ''Boston marriage'' became associated with Henry James's ''The Bostonians'' (1886), a novel involving a long-term co-habiting relationship between two unmarried women, "new women", although James himself never used the term. James' sister Alice lived in such a relationship with Katherine Loring and was among his sources for the novel. Some examples of women in "Bost ...

Deicing
Deicing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only deice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier. Deicing can be accomplished by mechanical methods (scraping, pushing); through the application of heat; by use of dry or liquid chemicals designed to lower the freezing point of water (various salts or brines, alcohols, glycols); or by a combination of these different techniques. Application areas Roadways In 2013, an estimated 14 million tons of salt were used for deicing roads in North America. Deicing of roads has traditionally been done with salt, spread by snowplows or dump trucks designed to spread it, often mixed with sand and gravel, on slick roads. Sodium chloride (rock salt) is normally used, as it is inexpensive and readily available in large quantities. However, since ...

Vincent Schaefer
Vincent Joseph Schaefer (July 4, 1906 – July 25, 1993) was an American chemist and meteorologist who developed cloud seeding. On November 13, 1946, while a researcher at the General Electric Research Laboratory, Schaefer modified clouds in the Berkshire Mountains by seeding them with dry ice. While he was self-taught and never completed high school, he was issued 14 patents. Personal life The Schaefer family lived in Schenectady, New York, and due to his mother's health, starting in 1921 the family made summer trips to the Adirondack Mountains. Vincent Schaefer had a lifelong association with the Adirondacks, as well as interests in hiking, natural history, and archeology. In his youth he was the founder of a local tribe of the Lone Scouts and with some of his tribe mates wrote and printed a tribe paper called "Archaeological Research." Schaefer credited this publication with his introduction to many prominent individuals in the Schenectady area, including Dr. Willis Rodney Whi ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Gone With The Wind (film)
''Gone with the Wind'' is a 1939 American epic historical romance film adapted from the 1936 novel by Margaret Mitchell. The film was produced by David O. Selznick of Selznick International Pictures and directed by Victor Fleming. Set in the American South against the backdrop of the American Civil War and the Reconstruction era, the film tells the story of Scarlett O'Hara ( Vivien Leigh), the strong-willed daughter of a Georgia plantation owner, following her romantic pursuit of Ashley Wilkes (Leslie Howard), who is married to his cousin, Melanie Hamilton (Olivia de Havilland), and her subsequent marriage to Rhett Butler (Clark Gable). The film had a troubled production. The start of filming was delayed for two years until January 1939 because of Selznick's determination to secure Gable for the role of Rhett. The role of Scarlett was difficult to cast, and 1,400 unknown women were interviewed for the part. The original screenplay by Sidney Howard underwent many revisions ...

Nanometer
330px, Different lengths as in respect to the molecular scale. The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American and British English spelling differences#-re, -er, American spelling) is a units of measurement, unit of length in the International System of Units (SI), equal to one billionth (short scale) of a metre () and to 1000 picometres. One nanometre can be expressed in scientific notation as , and as metres. History The nanometre was formerly known as the millimicrometre – or, more commonly, the millimicron for short – since it is of a micron (micrometre), and was often denoted by the symbol mμ or (more rarely and confusingly, since it logically should refer to a ''millionth'' of a micron) as μμ. Etymology The name combines the SI prefix ''nano-'' (from the Ancient Greek , ', "dwarf") with the parent unit name ''metre'' (from Greek , ', "unit of measurement"). ...

Monolayer
A monolayer is a single, closely packed layer of atoms, molecules, or cells. In some cases it is referred to as a self-assembled monolayer. Monolayers of layered crystals like graphene and molybdenum disulfide are generally called 2D materials. Chemistry A Langmuir monolayer or insoluble monolayer is a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough. Traditional compounds used to prepare Langmuir monolayers are amphiphilic materials that possess a hydrophilic headgroup and a hydrophobic tail. Since the 1980s a large number of other materials have been employed to produce Langmuir monolayers, some of which are semi-amphiphilic, including polymeric, ceramic or metallic nanoparticles and macromolecules such as polymers. Langmuir monolayers are extensively studied for the fabrication of Langmuir-Blodgett film (LB films), which are formed by transferred monolayers on a solid substrate. A Gibbs monolayer or ...

Ernest Rutherford
Ernest Rutherford, 1st Baron Rutherford of Nelson, (30 August 1871 – 19 October 1937) was a New Zealand physicist who came to be known as the father of nuclear physics. ''Encyclopædia Britannica'' considers him to be the greatest experimentalist since Michael Faraday (1791–1867). Apart from his work in his homeland, he spent a substantial amount of his career abroad, in both Canada and the United Kingdom. In early work, Rutherford discovered the concept of radioactive half-life, the radioactive element radon, and differentiated and named alpha and beta radiation. This work was performed at McGill University in Montreal, Quebec, Canada. It is the basis for the Nobel Prize in Chemistry he was awarded in 1908 "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances", for which he was the first Oceanian Nobel laureate, and the first to perform the awarded work in Canada. In 1904, he was elected as a member to the Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adsorption
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the ''adsorbate'' on the surface of the ''adsorbent''. This process differs from absorption, in which a fluid (the ''absorbate'') is dissolved by or permeates a liquid or solid (the ''absorbent''). Adsorption is a '' surface phenomenon'', while absorption involves the whole volume of the material, although adsorption does often precede absorption. The term ''sorption'' encompasses both processes, while ''desorption'' is the reverse of it. Like surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent or metallic) of the constituent atoms of the material are fulfilled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bon ...
