João Da Silva Feijó
João da Silva Barbosa or João da Silva Feijó, (1760 Rio de Janeiro – 1824), was a naturalist, mineralogist and Portuguese soldier, born in Brazil. João da Silva Feijó studied philosophy and mathematics at the University of Coimbra and adopted the name Feijó in homage to Benito Jerónimo Feijoo, Spanish philosopher, who at the time was respected among natural history students. In 1778, the Italian professor, Domenico Agostino Vandelli, was part of a group that founded the Natural History Museum in Lisbon. João da Silva was part of this group with Alexandre Rodrigues Ferreira, Manuel da Silva Galvão and Joaquim José da Silva. The feijoa, a tree that bears green fruits similar to guavas, is named after him. Cape Verde Beginning in 1783, scientific voyages under Vandelli were launched. Naturalists were to plan expeditions to various colonies. Feijó arranged to explore the islands of the archipelago of Cape Verde, and arrived there in June 1783. Like his colleagues ...

Potassium Nitrate
Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or ''saltpetre'' in the UK). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792 he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a proponent of th ...

Sulphur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
