Gas van
Gas vans were trucks with sealed compartments into which exhaust or carbon monoxide was pumped, used by Nazi Germany from late 1939 to murder disabled people, Jews, and other civilians.
Gas washing
Gas washing is a laboratory technique in which a gas stream bubbles through a liquid to clean, dry, or humidify it, typically using a Drechsel gas washing bottle.
Gas welding
Gas welding is a family of welding processes in which a fuel gas burned with oxygen produces a flame that melts metal edges so they fuse into a joint.
Gas Works Park
Gas Works Park is a 20-acre Seattle park on Lake Union, created 1973–1976 by Richard Haag from a 1906–1956 coal gasification plant, a pioneering post-industrial landscape with ongoing contamination cleanup and 2026 tower safety removals.
Gas-cooled fast reactor
A gas-cooled fast reactor is a proposed nuclear reactor combining a fast neutron spectrum with high-temperature helium cooling and a closed fuel cycle; it is one of six Generation IV systems.
Gas-diffusion-electrode CO2 electrolyzer
A gas-diffusion-electrode CO2 electrolyzer is an electrochemical flow cell that feeds gaseous CO2 directly to a catalyst layer on a porous electrode, raising current densities from tens of milliamperes to amperes per square centimeter.
Gas-discharge lamp
A gas-discharge lamp, also called an electric discharge lamp, is an electric light source that passes current through a gas or vapor, spanning fluorescent tubes and high-intensity discharge types.
Gas-dynamic trap
The gas-dynamic trap (GDT) is an axially symmetric magnetic mirror device for plasma confinement, first proposed and studied at the Budker Institute of Nuclear Physics in Novosibirsk.
Gas-generator cycle
The gas-generator cycle is an open liquid rocket engine power cycle in which a small fraction of propellant burned in a gas generator drives the turbine pumps, with exhaust dumped overboard.
Gas-insulated line
A gas-insulated line (GIL) is a high-voltage power transmission system in which a conductor inside a compressed insulating gas carries large amounts of power underground or through tunnels.
Gas-operated reloading
Gas-operated reloading, also called the gas-operated action, is a firearm mechanism that uses propellant gas from a fired cartridge to cycle the action and load the next round.
Gas-source molecular beam epitaxy
Gas-source molecular beam epitaxy, also called chemical beam epitaxy or gas source MBE, grows epitaxial semiconductor layers in vacuum from beams of gaseous sources like arsine.
GAS5
GAS5 (growth arrest specific 5, SNHG2) is a human long non-coding RNA gene at 1q25.1 that hosts snoRNAs, decoys the glucocorticoid receptor via a GRE mimic, and acts as a tumor suppressor downregulated in many cancers.
GAS6
GAS6 is a human gene on chromosome 13 that encodes Gas6, a vitamin K-dependent protein that activates the TAM receptor Axl and is implicated in thrombosis and cancer.
Gasa
Gasa (가사) is a Korean classical verse genre, established by the scholar-official sadaebu class in early Joseon, with unlimited four-beat lines that carry narrative and lyric content.
Gasabo District
Gasabo District, a district of Kigali City, Rwanda; largest and most populous district in Rwanda with 879,505 residents (2022 census), 15 sectors, 429.3 km2, density 2,056 per km2.
GASBOL Gas Pipeline
The GASBOL gas pipeline (Gasoduto Bolívia-Brasil) is a 3,150-kilometer natural gas pipeline from Rio Grande, Bolivia, to southern Brazil, the longest in South America, operating since 1999.
GASCADE Gastransport
GASCADE Gastransport is a German long-distance gas transmission system operator headquartered in Kassel, running a roughly 3,700-kilometer high-pressure pipeline network and converting growing portions of it to hydrogen.
Gascon campaign (1294–1303)
Gascon campaign (1294–1303), the Anglo-French War over the duchy of Aquitaine and Gascony: Philip IV declared the duchy confiscate in 1294, Charles of Valois overran it except Bordeaux and Bayonne, and the Treaty of Paris of 20 May 1303 restored Gascony to Edward I.
Gascony
Gascony (Gascogne, Gasconha), historical province of southwestern France named for the Vascones; a duchy from the 7th century, merged into Aquitaine in 1073, English-held 1152-1451, home of the Gascon Occitan language.
Gasdermin
Gasdermins (GSDMA-E plus PJVK/DFNB59) are pore-forming proteins executing pyroptosis; protease cleavage releases an N-terminal domain that oligomerizes into membrane pores, releasing IL-1β and IL-18.
Gasdermin-E
GSDME (gasdermin E, DFNA5, ICERE-1), human gene at 7p15.3 encoding a pore-forming gasdermin; caspase-3 cleavage converts apoptosis to pyroptosis; mutations cause autosomal dominant hearing loss; promoter methylation links it to cancer.
Gasene Gas Pipeline
The Gasene Gas Pipeline (Gasoduto de Integração Sudeste Nordeste) is a Brazilian natural gas pipeline linking Rio de Janeiro to Catu in Bahia, inaugurated in 2010.
Gåseøen
Gåseøen ("Goose Island") names several places: a flat bird-rich island in Vega Sund, East Greenland, named Gåsøya by NSIU in 1929, and a stone-ridge islet in Gurre Sø near Elsinore, Denmark.
Gaseous diffusion
Gaseous diffusion is a separation method in which a gas mixture passes through a porous barrier, used industrially to enrich uranium until the last plants closed in 2013.
Gaseous ionization detector
A gaseous ionization detector is a radiation detector that turns ionization in a gas into an electrical signal, including ionization chambers, proportional counters, and Geiger-Müller counters.
Gasflame nudibranch
The gasflame nudibranch (Bonisa nakaza) is a colorful sea slug found only in South African waters, from the Cape Peninsula to Port Elizabeth, reaching 10 cm in length.
Gasgrid Finland
Gasgrid Finland Oy is Finland's state-owned gas transmission system operator, created in 2020 when transmission was separated from Gasum; it also operates the Inkoo LNG terminal.
Gash Group
The Gash Group was a Bronze Age culture of the Gash Delta in eastern Sudan, known from the site of Mahal Teglinos and dated to the mid-3rd millennium BCE.
Gash-Barka Region
Gash-Barka (Zoba Gash-Barka, ዞባ ጋሽ ባርካ), also called Gash Barka, is Eritrea's largest and south-western region, capital Barentu, formed in 1995 from Gash-Setit; agricultural heartland with the Barka, Gash, and Tekeze rivers and the Bisha mine.
