Ludwig Clamor Marquart
Ludwig Clamor Marquart (29 March 1804 – 10 May 1881) was a German pharmacist and entrepreneur born in Osnabrück. As a teenager, he was a pharmacist's apprentice in the town of Dissen, and afterwards an assistant pharmacist in Lingen and Werden. Later he was an overseer of pharmacies in the district of Cologne, and in 1835 received a doctorate in pharmaceutical chemistry from the University of Heidelberg. In 1837 he started a private pharmaceutical institute in Bonn, where he taught classes until 1845. One of his students at the institute was renowned chemist Remigius Fresenius (1818-1897). In 1845 he founded in Bonn, ''Marquart's Lager chemischer Utensilien'', a factory that produced fine chemicals and pharmaceuticals. Today the operation in Bonn is part of Evonik; thus making it one of the oldest producers of chemicals in Germany. In 1835 Marquart is credited for coining the chemical term "anthocyanin" to denote the blue pigment of the cornflower. In 1842, Justus Carl Has ...

Remigius Fresenius
Carl Remigius Fresenius (28 December 1818 – 11 June 1897), was a German chemist, known for his studies in analytical chemistry. Biography Fresenius was born on 28 December 1818, in Frankfurt, Germany. After working for some time for a pharmacy in his native town, he entered Bonn University in 1840, and a year later migrated to Gießen, where he acted as assistant in Liebig's laboratory, and in 1843, became an assistant professor. In 1845, he was appointed to the chair of chemistry, physics and technology at the Wiesbaden Agricultural Institution, and three years later, he became the first director of the chemical laboratory which he induced the Nassau government to establish at that place. Under his leadership and direction, this laboratory continuously increased in size and popularity, a school of pharmacy being added in 1862 (though given up in 1877) and an agricultural research laboratory in 1868. Apart from his administrative duties, Fresenius occupied himself almost exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Osnabrück
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pandanaceae
Pandanaceae is a family of flowering plants native to the tropics and subtropics of the Old World, from West Africa to the Pacific. It contains 982 known species in five genera, of which the type genus, ''Pandanus'', is the most important, with species like '' Pandanus amaryllifolius'' and karuka (''Pandanus julianettii'') being important sources of food. The family likely originated during the Late Cretaceous. Characteristics Pandanaceae includes trees, shrubs, lianas, vines, epiphytes, and perennial herbs. Stems may be simple or bifurcately branched, and may have aerial prop roots. The stems bear prominent leaf scars. The leaves are very long and narrow, sheathing, simple, undivided, with parallel veins; the leaf margins and abaxial midribs are often prickly. The plants are dioecious. The inflorescences are terminally borne racemes, spikes or umbels, with subtended spathes, which may be brightly colored. The flowers are minute and lack perianths. Male flowers contain numero ...

Justus Carl Hasskarl
Justus Carl Hasskarl (6 December 1811 – 5 January 1894) was a German explorer and botanist specializing in pteridophytes, bryophytes and spermatophytes. Biography Justus Carl Hasskarl was born in Kassel in the Kingdom of Westphalia. In his earlier life he studied at a Botanical Garden, Bonn, plant nursery in Poppelsdorf in 1827. In 1834 he studied natural history while at the same time preparing himself for an expedition to the tropics. In 1836, he traveled to Java and tried to make a living through his knowledge in physics and medicine, with little success. Subsequently, he sent a request to the governor general to work in the Bogor Botanical Gardens, National Botanical Garden and a year later he was appointed assistant curator. With director Johannes Elias Teijsmann, they rearranged their crops to taxonomic families, which would result in the displacement of many specimens in the botanical garden. Together they organized expeditions to various parts of modern Indonesi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornflower
''Centaurea cyanus'', commonly known as cornflower or bachelor's button (among other names), is an annual flowering plant in the family Asteraceae native to Europe. In the past, it often grew as a weed in cornfields (in the broad sense of "corn", referring to Food grain, grains, such as wheat, barley, rye, or oats), hence its name. It is now endangered species, endangered in its native habitat by agriculture, agricultural intensification, particularly by over-use of herbicides. However, ''Centaurea cyanus'' is now also naturalisation (biology), naturalised in many other parts of the world, including North America and parts of Australia through introduction as an ornamental plant in gardens and as a seed contaminant in crop seeds. Description ''Centaurea cyanus'' is an annual plant growing to tall, with grey-green branched stems. The leaves are lanceolate and long. The flowers are most commonly an intense blue colour and arranged in inflorescence, flowerheads (capitula) of 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pigment
A pigment is a powder used to add or alter color or change visual appearance. Pigments are completely or nearly solubility, insoluble and reactivity (chemistry), chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use. Dyes are often organic compounds whereas pigments are often inorganic compound, inorganic. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic chemistry, inorganic, organic chemistry, organic, and special pigments were marketed worldwide. According to an April 2018 report by ''Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each yea ...

Anthocyanin
Anthocyanins (), also called anthocyans, are solubility, water-soluble vacuole, vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black. In 1835, the German pharmacist Ludwig Clamor Marquart named a chemical compound that gives flowers a blue color, Anthokyan, in his treatise "''Die Farben der Blüthen''" (English: The Colors of Flowers). Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins. Anthocyanins belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway. They can occur in all biological tissue, tissues of higher plants, including leaf, leaves, plant stem, stems, roots, flowers, and fruits. Anthocyanins are derived from anthocyanidins by adding sugars. They are odorless and moderately astringent. Although approved as food and beverage c ...

Fine Chemical
In chemistry, fine chemicals are complex, single, pure chemical substances, produced in limited quantities in multipurpose plants by multistep batch chemical or biotechnological processes. They are described by exacting specifications, used for further processing within the chemical industry and sold for more than $10/kg (see the comparison of fine chemicals, commodities and specialties). The class of fine chemicals is subdivided either on the basis of the added value (building blocks, advanced intermediates or active ingredients), or the type of business transaction, namely standard or exclusive products. Fine chemicals are produced in limited volumes ( $10/kg) according to exacting specifications, mainly by traditional organic synthesis in multipurpose chemical plants. Biotechnical processes are gaining ground. Fine chemicals are used as starting materials for specialty chemicals, particularly pharmaceuticals, biopharmaceuticals and agrochemicals. Custom manufa ...
