Poligny, Jura
Poligny () is a commune in the Jura department in Bourgogne-Franche-Comté in eastern France. The town stands at the foot of the first plateau of the Jura region, with limestone cliffs rising to its east and south, and a steephead valley leading to the village of Vaux-sur-Poligny to the east. On the cliffs to the east is a notable cave, known as "Le Trou de la Lune" (the Moonhole); on the cliffs to the south is a large cross, the "Croix du Dan". A network of hiking trails surrounds the town and provide routes to both these viewpoints, and the GR 59 long distance footpath runs through the town. First Empire general Jean-Pierre Travot was born in Poligny; a statue in his honour stands in the principal square of the town, the Place des Déportés, and a road is named after him. Poligny is served by the railway line from Besançon to Lons-le-Saunier. The town is recognised as the " Capital of Comté", with a third of the region's production of this much-loved cheese bei ...

Phosphorus
Phosphorus is a chemical element; it has Chemical symbol, symbol P and atomic number 15. All elemental forms of phosphorus are highly Reactivity (chemistry), reactive and are therefore never found in nature. They can nevertheless be prepared artificially, the two most common allotropes being white phosphorus and red phosphorus. With as its only stable isotope, phosphorus has an occurrence in Earth's crust of about 0.1%, generally as phosphate rock. A member of the pnictogen family, phosphorus readily forms a wide variety of organic compound, organic and inorganic compound, inorganic compounds, with as its main oxidation states +5, +3 and −3. The isolation of white phosphorus in 1669 by Hennig Brand marked the scientific community's first discovery since Antiquity of an element. The name phosphorus is a reference to the Phosphorus (morning star), god of the Morning star in Greek mythology, inspired by the faint glow of white phosphorus when exposed to oxygen. This property is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Match
A match is a tool for starting a fire. Typically, matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by friction generated by striking the match against a suitable surface. Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder (material), binder, often colored for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used. Etymology The word ''match'' derives from Old French ''mèche'', referring to the Candle wick, wick of a candle. Historically, the term ''match'' referred to lengths of rope, cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to li ...

Joseph Louis Gay-Lussac
Joseph Louis Gay-Lussac ( , ; ; 6 December 1778 – 9 May 1850) was a French chemist and physicist. He is known mostly for his discovery that water is made of two parts hydrogen and one part oxygen by volume (with Alexander von Humboldt), for two laws related to gases, and for his work on alcohol–water mixtures, which led to the degrees Gay-Lussac used to measure alcoholic beverages in many countries. Biography Gay-Lussac was born at Saint-Léonard-de-Noblat in the present-day department of Haute-Vienne. His father, Anthony Gay, son of a doctor, was a lawyer and prosecutor and worked as a judge in Noblat Bridge. Father of two sons and three daughters, he owned much of the Lussac village and began to add the name of this hamlet to his name, following a custom of the Ancien Régime. Towards the year 1803, father and son formally adopted the name Gay-Lussac. During the Revolution, under the Law of Suspects, his father, former king's attorney, was imprisoned in Saint L ...

Potassium Chlorate
Potassium chlorate is the inorganic compound with the molecular formula KClO3. In its pure form, it is a white solid. After sodium chlorate, it is the second most common chlorate in industrial use. It is a strong oxidizing agent and its most important application is in safety matches. In other applications it is mostly obsolete and has been replaced by safer alternatives in recent decades. It has been used * in fireworks, propellants and explosives, * to prepare oxygen, both in the lab and in chemical oxygen generators, * as a disinfectant, for example in dentifrices and medical mouthwashes, * in agriculture as an herbicide. Production On the industrial scale, potassium chlorate is produced by the salt metathesis reaction of sodium chlorate and potassium chloride: : The reaction is driven by the low solubility of potassium chlorate in water. The equilibrium of the reaction is shifted to the right hand side by the continuous precipitation of the product (Le Chatelier's Principle). T ...

Sulfur
Sulfur ( American spelling and the preferred IUPAC name) or sulphur ( Commonwealth spelling) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the 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 common 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". Almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere Th ...

Gum Arabic
Gum arabic (gum acacia, gum sudani, Senegal gum and by other names) () is a tree gum exuded by two species of '' Acacia sensu lato:'' '' Senegalia senegal,'' and '' Vachellia seyal.'' However, the term "gum arabic" does not indicate a particular botanical source. The gum is harvested commercially from wild trees, mostly in Sudan (about 70% of the global supply) and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" (''al-samgh al-'arabi'') was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports and retained its name of origin. Gum arabic is a complex mixture of glycoproteins and polysaccharides, predominantly polymers of arabinose and galactose. It is soluble in water, edible, and used primarily in the food industry and soft drink industry as a stabilizer, with E number E414 (I414 in the US). Gum arabic is a key ingredient in traditional lithography and is used in printing, paints, glue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Walker (inventor)
John Walker (29 May 1781 – 1 May 1859) was an English inventor who invented the Match#Friction matches, friction match. Life Walker was born in Stockton-on-Tees, County Durham, in 1781. He went to the local grammar school and was afterwards apprenticed to Watson Alcock, the principal Surgery, surgeon of the town, serving him as an assistant. He had, however, an aversion to surgical operations and had to leave the profession, turning instead to chemistry. After studying at Durham, England, Durham and York he set up a small business as a chemist and Dispensing chemist, druggist at 59 High Street, Stockton, around 1818. Walker died in Stockton on 1 May 1859 and was buried in the grounds of St Mary's Church in Norton, County Durham, Norton, near Stockton.

Berne Convention (1906)
__NOTOC__ The Berne Convention (formally, the International Convention respecting the Prohibition of the Use of White (Yellow) Phosphorus in the Manufacture of Matches ()) of 1906 is a multilateral treaty negotiated in Berne, Switzerland, which prohibits the use of white phosphorus in the manufacture of matches. The treaty also prohibits the import and sale of such matches. The background to the treaty was the extensive medical problems such as phossy jaw facing workers in match production. The treaty was concluded on 26 September 1906. It entered into force on 1 January 1912. The Convention remains in force for 48 states. Switzerland is the depositary for the treaty. In 1925 Edward J. Phelan, future Director General of the International Labour Organization The International Labour Organization (ILO) is a United Nations agency whose mandate is to advance social and economic justice by setting international labour standards.
