Clydach, Swansea
Clydach is both a village and a community in Swansea, Wales, within the Clydach ward and the Llangyfelach parish. It is located northeast of Swansea city centre. In 2011, the population was 7,503. Welsh is the first language of 24 per cent of the population and both Welsh and English language schools are available. The village lies close to the M4 motorway which can be accessed via the bypass or old road via Ynystawe. The community includes part of the village of Glais. History In the 1800s, Clydach was a very small community if it could even be called that. Maps from then show Clydach to consist of sub-areas namely 'Mount Pleasant' (the area by high street shops), 'Faerdre' (covering the area nearest to Vardre Road), 'Down' the area that was once 'Down Farm' which is now land laying behind the Farmer's Arms, Clydach and below 'Ty gwyn Road'. There was also an area called Ty Gwyn as Ty Gwyn/White House was present on the land. The road leading to Ty Gwyn is now Ty Gwyn Road an ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Tawe
The River Tawe (; cy, Afon Tawe ) is a long river in South Wales. Its headwaters flow initially east from its source below Llyn y Fan Fawr south of Moel Feity in the Black Mountains, the westernmost range of the Brecon Beacons National Park, before the river turns south and then southwest to its estuary at Swansea. Its main tributaries are the right bank Upper and Lower Clydach Rivers and the Afon Twrch. The total area of the catchment is some . The Tawe passes through a number of towns and villages including Ystradgynlais, Ystalyfera, Pontardawe, and Clydach and meets the sea at Swansea Bay below Swansea. The Tawe Valley ( in Welsh) is more commonly known as the Swansea Valley. Ownership of the riverbed was granted to the Duke of Beaufort in the 17th century by Charles II resulting in exclusive mineral and fishing rights, which is extended as far as requiring permission and payment for bridges which are built over it. This was last exercised in 2008 when Swansea Cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Pollutants
Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, carbon dioxide and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). Air pollution can be caused by both human activities and natural phenomena. Air pollution is a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, ...

Toyota Prius
The is a car built by Toyota which has a Hybrid vehicle drivetrain, hybrid drivetrain, combining an internal combustion engine with an electric motor. Initially offered as a four-door Sedan (automobile), sedan, it has been produced only as a five-door liftback since 2003. In 2007, the United States Environmental Protection Agency (EPA) and California Air Resources Board (CARB) rated the Prius as among the cleanest vehicles sold in the United States on the basis of smog-forming emissions. The 2018 model year Prius Eco ranked as the second-most-fuel-efficient gasoline-powered car without plug-in electric vehicle, plug-in capability available in the US that year, following the Hyundai Ioniq, Hyundai Ioniq Blue hybrid. The Prius first went on sale in Japan in 1997, and was available at Toyota dealerships (Japan), all four Toyota Japan dealership chains, making it the first mass-produced hybrid vehicle. It was subsequently introduced worldwide in 2000. Toyota sells the Prius in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Refining (metallurgy)
In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgy, pyrometallurgical and hydrometallurgy, hydrometallurgical techniques. Lead Cupellation One ancient process for extracting the silver from lead was cupellation. Lead was melted in a bone ash 'test' or 'cupel' and air blown across the surface. This oxidised the lead to litharge, and also oxidised other base metals present, the silver (and gold if present) remaining unoxidised. In the 18th century, the process was carried on using a kind of reverberatory furnace, but differing from the usual kind in that air was blown over the surface of the molten lead from bellows or (in the 19th century) blowing cyl ...

Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Ludwig Mond
Ludwig Mond FRS (7 March 1839 – 11 December 1909) was a German-born, British chemist and industrialist. He discovered an important, previously unknown, class of compounds called metal carbonyls. Education and career Ludwig Mond was born into a Jewish family in Kassel, Germany. His parents were Meyer Bär (Moritz) Mond and Henrietta Levinsohn. After attending schools in his home town, he studied chemistry at the University of Marburg under Hermann Kolbe and at the University of Heidelberg under Robert Bunsen but he never gained a degree. He then worked in factories in Germany and the Netherlands before coming to England to work at the factory of John Hutchinson & Co in Widnes in 1862. He worked in Utrecht for the firm of P. Smits & de Wolf from 1864 to 1867 and then returned to Widnes. Here he formed a partnership with John Hutchinson and developed a method to recover sulphur from the by-products of the Leblanc process, which was used to manufacture soda ash. In 1872 Mo ...
