Tungnath (तुंगनाथ)
Tungnath (तुंगनाथ) is a Hindu temple of Shiva in Uttarakhand, India, perched at about 3,680 m and regarded as the highest Shiva temple in the world.
Tungstate
Tungstate is the divalent anion WO₄²⁻, the fully deprotonated form of tungstic acid, and any salt containing it; its minerals scheelite and wolframite are the chief ores of tungsten metal.
Tungsten
Tungsten, also known as wolfram, is a hard, steel-gray transition metal with the highest melting point of any metal, 3414 °C, best known for tungsten carbide tools and light bulb filaments.
Tungsten bronzes
Tungsten bronzes are non-stoichiometric compounds of formula MxWO3, in which metal atoms enter the tungsten trioxide lattice; they are named for their bronze-like luster, not because they contain bronze.
Tungsten carbide
Tungsten carbide is an extremely hard compound of tungsten and carbon, best known as the hard phase of cemented carbide used in cutting and drilling tools.
Tungsten diselenide
Tungsten diselenide (WSe₂) is a layered two-dimensional semiconductor of tungsten and selenium whose monolayer has a direct bandgap, and which enables complementary logic, optoelectronics, and moiré superconductivity.
Tungsten disulfide
Tungsten disulfide (WS₂) is an inorganic compound of tungsten and sulfur that occurs as the rare mineral tungstenite and is used as a dry film lubricant.
Tungsten ditelluride
Tungsten ditelluride (WTe₂) is a layered transition-metal dichalcogenide semimetal, prominent in physics since 2014 for extremely large, non-saturating magnetoresistance and 2015 type-II Weyl semimetal predictions.
Tungsten divertor
A tungsten divertor is the bottom structure of a tokamak that exhausts heat and helium ash, its plasma-facing surface made of water-cooled tungsten, chosen for ITER.
Tungsten fill
Tungsten fill is the semiconductor manufacturing step that fills contact holes and vias with CVD-deposited tungsten, forming the industry's standard conductive plug since the late 1980s.
Tungsten fuzz
Tungsten fuzz is a porous nanostructure of thin tungsten nanotendrils that forms on hot tungsten under helium ion bombardment, studied as a degradation route for fusion device components.
Tungsten hexafluoride
Tungsten hexafluoride (WF6), also called wolfram hexafluoride, is a dense, colorless gas that boils at 17.1 °C and is the standard precursor for chemical vapor deposition of tungsten in semiconductor manufacturing.
Tungsten trioxide
Tungsten trioxide (WO₃) is an n-type semiconductor oxide of tungsten, best known as the standard electrochromic material in smart windows and the intermediate from which tungsten metal is made.
Tungurahua (district)
Tungurahua province, Ecuador (capital Ambato), created 3 July 1860 as Ambato province, renamed 1861 after Tungurahua volcano; nine cantons, 563,532 people (2022), 3,335 km2, second smallest province.
Tungurahua (landform)
Tungurahua, an active 5,023 m andesitic stratovolcano in Ecuador's Eastern Cordillera near Baños, erupted 1999–2016 with Strombolian, Vulcanian, and pyroclastic activity, frequent rain-generated lahars, and now sits in repose.
Tungurahua Volcano UNESCO Global Geopark
Tungurahua Volcano UNESCO Global Geopark (Geoparque Mundial UNESCO Volcán Tungurahua), designated April 10, 2025, is Ecuador's third geopark: 2,397 km² in Tungurahua and Chimborazo provinces around an active subduction-zone volcano, with 20 geosites and 417 million years of geological history.
Tungusic languages
Tungusic (Manchu-Tungusic) languages: a small family of about 12 endangered languages of Siberia, the Russian Far East, and northeast China, with four branches (Ewenic, Udiheic, Nanaic, Jurchenic), suffixing SOV grammar, vowel harmony, and disputed wider Altaic/Transeurasian affinities.
Tungusic peoples
Tungusic peoples are the ethnolinguistic groups speaking Tungusic languages across Siberia, Manchuria, and Xinjiang, including Evenks, Evens, Nanai, Oroqen, Xibe, and Manchus; about twenty endangered languages, with Manchu the Qing official language.
Tunguska Basin
The Tunguska Basin (Тунгусский угольный бассейн) is a vast coal basin in Siberia, Russia, holding about 3 trillion tons of coal and ranking among the world's largest by reserves.
Tunguska event
The Tunguska event, also called the Tunguska blast, was a powerful airburst over central Siberia on June 30, 1908, flattening about 2,150 square kilometers of forest without a crater.
Tunic
Tunic: a simple slip-on garment, sleeved or sleeveless, usually knee-length or longer and often belted. From Latin tunica; primary male garment in ancient Peru (uncu) and the basic garment of Rome, Egypt, and Byzantium.
Tunic (military)
The military tunic is a thigh-length uniform coat that replaced the waist-length coatee in most armies from the mid-19th century; introduced in the British Army in 1855 during the Crimean War, in scarlet, khaki, and olive drab patterns.
Tunic (video game)
Tunic is a 2022 isometric action-adventure game by Andrew Shouldice (Isometricorp Games), published by Finji, starring a fox who rebuilds a runic instruction manual; Zelda-inspired, Souls-like combat, Golden Path meta-puzzle, PC, Xbox, PlayStation, Switch.
Tunicate
Tunicates (sea squirts, Urochordata) are marine chordate invertebrates, sister group to vertebrates, with a cellulose tunic, filter feeding, sessile adults, and uses in food, feed, and pharmaceuticals.
Tunicate swarm algorithm
The tunicate swarm algorithm (TSA) is a swarm-based metaheuristic for derivative-free global optimization, introduced in 2020 and modeled on the jet propulsion and foraging of marine tunicates.
Tunicates of Ireland
Tunicates of Ireland: sea squirts (Urochordata) in Irish waters, 72 recorded species, over 65 ascidians, six invasive including Styela clava and Didemnum vexillum, threatening shellfish aquaculture.
Tuning fork
A tuning fork is a U-shaped metal resonator that produces a nearly pure tone at a fixed frequency when struck, invented by John Shore in 1711 as a pitch standard for musicians.
