Chemurgy
Chemurgy is a branch of applied chemistry concerned with preparing industrial products from agricultural raw materials. The concept developed by the early years of the 20th century. For example, products such as brushes and motion picture film were made from cellulose. Beginning in the 1920s, William J. Hale, agricultural journalist Wheeler McMillen, and other Americans began advocating a greater link between farmers and industry. The word "chemurgy" was coined by chemist William J. Hale and first publicized in his 1934 book ''The Farm Chemurgic''. The ''Hemp Body or Soybean Car'' Automaker Henry Ford began to test farm crops for their industrial potential around 1930, and soon settled on hemp and the soybean as particularly promising (the famous Hemp Body or ''Soybean Car''). The Ford Motor Company used soybeans in such parts as gearshift knobs and horn buttons, and hemp for the body of the car. The automobile was designed to run on hemp diesel. Ford Motor Company accessed these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Semisynthesis
Semisynthesis, or partial chemical synthesis, is a type of chemical synthesis that uses chemical compounds isolated from natural sources (such as microbiology, microbial cell cultures or plant material) as the starting materials to produce novel compounds with distinct chemical and medicinal properties. The novel compounds generally have a high molecular weight or a complex molecular structure, more so than those produced by total synthesis from simple starting materials. Semisynthesis is a means of preparing many medicines more cheaply than by total synthesis since fewer chemical steps are necessary. Drugs derived from natural sources are commonly produced either by isolation from their natural source or, as described here, through semisynthesis of an isolated agent. From the perspective of chemical synthesis, living organisms act as highly efficient chemical factories, capable of producing structurally complex compounds through biosynthesis. In contrast, engineered chemical s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
George Washington Carver
George Washington Carver ( 1864 – January 5, 1943) was an American Agricultural science, agricultural scientist and inventor who promoted alternative crops to cotton and methods to prevent soil depletion. He was one of the most prominent black scientists of the early 20th century. While a professor at Tuskegee Institute, Carver developed techniques to improve types of soils depleted by repeated plantings of cotton. He wanted poor farmers to grow other crops, such as peanuts and sweet potatoes, as a source of their own food and to improve their quality of life. Under his leadership, the Experiment Station at Tuskegee published over forty practical bulletins for farmers, many written by him, which included recipes; many of the bulletins contained advice for poor farmers, including combating soil depletion with limited financial means, producing bigger crops, and preserving food. Apart from his work to improve the lives of farmers, Carver was also a leader in promoting environm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Albany, California
Albany ( ) is a city on the east shore of San Francisco Bay in northwestern Alameda County, California, United States. The population was 20,271 at the 2020 United States census. History In 1908, a group of local women protested the dumping of Berkeley garbage in their community. Armed with two shotguns and a twenty-two-caliber rifle, they confronted the drivers of the wagons near what is now the corner of San Pablo Avenue and Buchanan Street. The women told the drivers of the horse-drawn garbage wagons to go home, which they did quickly and without complaint. Shortly thereafter, the residents of the town voted to incorporate as the City of Ocean View. In 1909, voters changed the name of the city, primarily to distinguish the city from the adjacent section of Berkeley which had previously been named Ocean View. On a vote of 38 to 6 the city was renamed in honor of Albany, New York, the birthplace of the city's first mayor, Frank Roberts. The Albany Sauna is one of the ...

Decorticator
A decorticator (from Latin: ''cortex'', bark) is a machine for stripping the skin, bark, or rind off nuts, wood, plant stalks, grain, etc., in preparation for further processing. History In 1933, a farmer named Bernagozzi from Bologna manufactured a machine called a ''"scavezzatrice"'', a decorticator for hemp. A working hemp decorticator from 1890, manufactured in Germany, is preserved in a museum in Bologna. In Italy, the''"scavezzatrice"'' faded in the 1950s because of monopolisation from fossil fuel, paper interests, synthetic materials and from other less profitable crops. Many types of decorticators have been developed since 1890. In 1919, George Schlichten received a U.S. 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 sufficiency of disclosure, enabling discl ... on his improvements of the decorticat ...

Castor Oil
Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant ''Ricinus communis''. The seeds are 40 to 60 percent oil. It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is and its density is 0.961 g/cm3. It includes a mixture of triglycerides in which about 90 percent of fatty acids are Ricinoleic acid, ricinoleates. Oleic acid and linoleic acid are the other significant components. Some 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced annually for a variety of uses. Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold-resistant plastics, waxes and polishes, nylon, and perfumes. Etymology The name probably comes from a confusion between the ''Ricinus'' plant that produces it and another plant, the ''Vitex agnus-castus''. An alternative etymology, though, suggests that it was used as a replace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Jute
Jute ( ) is a long, rough, shiny bast fibre that can be Spinning (textiles), spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', of the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olitorius'', but such fiber is considered inferior to that derived from ''Corchorus capsularis''. Jute fibers, composed primarily of cellulose and lignin, are collected from bast (the phloem of the plant, sometimes called the "skin"). The industrial term for jute fiber is ''raw jute''. The fibers are off-white to brown and range from long. In Bangladesh, jute is called the "golden fiber" for its color and monetary value. The bulk of the jute trade is centered in South Asia, with India and Bangladesh as the primary producers. The majority of jute is used for durable and sustainable packaging, such as Gunny sack, burlap sacks. Its production and usage declined as Disposable product, disposable plastic packaging became common, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Kenaf
Kenaf [etymology: Persian], ''Hibiscus cannabinus'', is a plant in the family Malvaceae also called Deccan hemp and Java jute. ''Hibiscus cannabinus'' is in the genus ''Hibiscus'' and is native to Africa, though its exact origin is unknown. The name also applies to the fibre obtained from this plant. Kenaf is one of the allied fibres of jute and shows similar characteristics. Common names *Europe: **English: Deccan hemp, Java jute, wild stockrose **French language, French: chanvre de Bombay, chanvre du Deccan, chanvre de Guinée, chanvre de Gambo, chanvre de roselle, jute de Java, jute de Siam, kénaf, ketmie à feuilles de chanvre (Belgium), roselle **German language, German: Ambari, Dekkanhanf, Gambohanf, Hanfeibisch, Javajute, Kenaf, Rosellahanf, Roselle, Siamjute **Portuguese language, Portuguese: cânhamo rosella, juta-de-java, juta-do-sião, quenafe **Spanish language, Spanish: cáñamo de la India, cáñamo de gambo, cáñamo Rosella, pavona encendida, yute de Java, yute ...

Newsweek
''Newsweek'' is an American weekly news magazine based in New York City. Founded as a weekly print magazine in 1933, it was widely distributed during the 20th century and has had many notable editors-in-chief. It is currently co-owned by Dev Pragad, the president and chief executive officer (CEO), and Johnathan Davis, who sits on the board; each owns 50% of the company. In August 2010, revenue decline prompted Graham Holdings, the Washington Post Company to sell ''Newsweek'' to the audio pioneer Sidney Harman for one US dollar and an assumption of the magazine's liabilities. Later that year, ''Newsweek'' merged with the news and opinion website ''The Daily Beast'', forming The Newsweek Daily Beast Company, later called ''NewsBeast''. ''Newsweek'' was jointly owned by the estate of Harman and the company IAC (company), IAC. ''Newsweek'' continued to experience financial difficulties, leading to the suspension of print publication at the end of 2012. In 2013, IBT Media acquired ...

Hemp
Hemp, or industrial hemp, is a plant in the botanical class of ''Cannabis sativa'' cultivars grown specifically for industrial and consumable use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, Bioplastic, biodegradable plastics, paint, Thermal insulation, insulation, biofuel, food, and Fodder, animal feed. Although chemotype I cannabis and hemp (types II, III, IV, V) are both ''Cannabis sativa'' and contain the psychoactive component tetrahydrocannabinol (THC), they represent distinct cultivar groups, typically with unique phytochemistry, phytochemical compositions and uses. Hemp typically has lower concentrations of total THC and may have higher concentrations of cannabidiol (CBD), which potentially mitigates the Psychoactive ...

Life Jacket
A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water. The device will keep the wearer afloat with their head and mouth above the surface – they do not have to swim or tread water in order to stay afloat and can even be unconscious. PFDs are commonly worn on small watercraft or other locations where accidental entry into deep water may occur in order to provide immediate support for the wearer should they end up in the water. PFDs are also kept on large vessels for passengers to wear in an emergency in order to help them stay afloat should they be forced to enter the water or accidentally fall overboard during an evacuation. PFDs are commonly worn for swimming and other activities that require an individual to be in water. This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Asclepias
''Asclepias'' is a genus of herbaceous, perennial, flowering plants known as milkweeds, named for their latex, a milky substance containing cardiac glycosides termed cardenolides, exuded where cells are damaged. Most species are toxic to humans and many other species, primarily due to the presence of cardenolides. However, as with many such plants, some species feed upon milkweed leaves or the nectar from their flowers. A noteworthy feeder on milkweeds is the monarch butterfly, which uses and requires certain milkweeds as host plants for its larvae. The ''Asclepias'' genus contains over 200 species distributed broadly across Africa, North America, and South America. It previously belonged to the family Asclepiadaceae, which is now classified as the subfamily Asclepiadoideae of the dogbane family, Apocynaceae. The genus was formally described by Carl Linnaeus in 1753, who named it after Asclepius, the Greek god of healing. Flowers Members of the genus produce some of the ...

Taraxacum Kok-saghyz
''Taraxacum kok-saghyz'', often abbreviated as ''TKS'' and commonly referred to as the Kazakh dandelion, rubber root, or Russian dandelion, is a species of dandelion native to Kazakhstan, Kyrgyzstan and Uzbekistan, notable for its production of high-quality rubber. ''T. kok-saghyz'' was discovered in Kazakhstan in 1932 by Soviet Union, Soviet scientists seeking a domestic source of rubber. Etymology ''Kok-saghyz'' is derived from the Kazakh ''kök-sağız'' (көк-сағыз), with ''kök'' meaning green and ''saghyz'' meaning rubber or gum. Its latex was traditionally used as a kind of chewing gum. Description ''Taraxacum kok-saghyz'' is a perennial plant with a yellow composite flower characteristic of the genus ''Taraxacum''. Each flower head may be approximately one inch in diameter and be made up for 50 to 90 florets. Plants may contain 25 to 50 leaves arranged in one or more rosettes at the upper end of the root. ''Taraxacum kok-saghyz'' can be differentiated from the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
