Antimony selenide solar cell

An antimony selenide solar cell is a thin-film photovoltaic device using antimony selenide (Sb₂Se₃), an earth-abundant, low-toxicity absorber, as a candidate alternative to CdTe and CIGS, with record efficiencies of 10.12%.

Antimony sulfide selenide solar cells

Antimony sulfide selenide solar cells are thin-film photovoltaic devices using an antimony sulfoselenide absorber with a tunable 1.1–1.8 eV bandgap and record efficiencies of about 11%.

Antimony telluride

Antimony telluride (Sb₂Te₃) is a narrow-bandgap p-type semiconductor of the layered tetradymite family, used as a room-temperature thermoelectric and studied as a 3D topological insulator with a single Dirac cone.

Antimony tin oxide

Antimony tin oxide (ATO), also written antimony-doped tin oxide, is a transparent conducting oxide combining about 80 percent transparency with low resistivity, used in transparent electrodes and infrared-shielding window coatings.

Antimony trichloride

Antimony trichloride (SbCl₃), known to the alchemists as butter of antimony, is a soft colorless crystalline solid that serves as a Lewis acid, catalyst, and colorimetric reagent for vitamin A.

Antimony Trioxide

Antimony trioxide (Sb2O3) is an odorless white crystalline powder, the most commercially significant form of antimony, used mainly as a synergist for halogenated flame retardants in plastics and textiles.

Antimony trisulfide

Antimony trisulfide (Sb2S3) is an inorganic compound of antimony and sulfide, found in nature as stibnite, used in gunpowder, matches, and fireworks, and studied as a low-loss phase-change material for photonics.

Antimony/bismuth chalcohalide absorbers

Antimony/bismuth chalcohalide absorbers are nontoxic semiconductor materials for solar cells that contain antimony or bismuth with chalcogen and halide anions, studied as stable alternatives to lead-halide perovskites.

Antimycin A

Antimycin A is a depsipeptide natural product produced by Streptomyces bacteria that blocks mitochondrial Complex III, halting ATP synthesis; it is used as a fish toxicant.

Antin Holovaty

Antin Holovaty (Антін Головатий, 1744–1797) was a Ukrainian Cossack military leader and poet who served as military judge and kish otaman of the Black Sea Cossack Host.

Antinatalism

Antinatalism is the philosophical view that procreation is morally wrong, also called anti-natalism. Its most influential academic formulation is David Benatar's 2006 asymmetry argument; it divides into anthropocentric and sentiocentric (efilist) branches.

Antineoplastic

Antineoplastic agents are drugs that block or kill cancer cells, spanning cytotoxic chemotherapy classes (alkylating agents, antimetabolites, plant alkaloids, antitumor antibiotics), immunotherapy, and targeted therapy; many are hazardous occupational drugs and some treat non-cancer diseases.

Antineoplastic Combined Chemotherapy Protocols

Antineoplastic Combined Chemotherapy Protocols (MeSH D000971), also called combination chemotherapy regimens or anticancer drug combinations, are multi-drug cancer treatment protocols designed to raise tumor cell killing and delay drug resistance at the cost of added toxicity.

Antineoplastic Protocols

Antineoplastic Protocols (Cancer Treatment Protocols) are clinical protocols to inhibit growth or spread of neoplasms; a MeSH descriptor D024221 introduced in 2002, covering combination cancer treatment plans and guideline adherence.

Antineutrino

An antineutrino is the antiparticle of the neutrino, an electrically neutral, nearly massless particle emitted in beta-minus decay and first detected at the Savannah River reactor in 1956.

Antineutron

The antineutron is the antiparticle of the neutron, with the same mass and no electric charge but antiquarks inside, discovered in 1956 at the Bevatron in Berkeley.

Antinoeion at Hadrian's Villa

Antinoeion: sanctuary excavated 2002–2005 at Hadrian's Villa, Tivoli, identified by Zaccaria Mari as the temple-tomb of Antinous, Hadrian's deified lover; three temples, possible obelisk, summer-solstice sunrise alignment, tomb identification contested.

Antinomian Controversy

The Antinomian Controversy, also known as the Free Grace Controversy, was a 1636–1638 theological and political conflict in the Massachusetts Bay Colony in which Anne Hutchinson and John Wheelwright were banished.

Antinomianism

Antinomianism, from Greek for "against law," is the doctrine or charge that Christians are freed by grace from obeying God's moral law, coined by Martin Luther against Johannes Agricola.

Antinous (crater on Tethys)

Antinous is a 138-km-diameter impact crater in the far southern latitudes of Saturn's moon Tethys, IAU-named in 1982 after the chief suitor slain by Odysseus in Homer's Odyssey; it is not crater-saturated and records a low heat flux.

Antinous (Ἀντίνοος)

Antinous (Antinoos) was a Bithynian youth and companion of Emperor Hadrian who drowned in the Nile in 130 CE, after which Hadrian deified him extravagantly.

Antinuclear antibody

Antinuclear antibodies (ANAs) are autoantibodies against nuclear components, detected by HEp-2 indirect immunofluorescence or solid-phase assays; positive in 95-100% of SLE but also in about 5% of healthy adults.

Antioch

Antioch (Antakya, Turkish Antakya), ancient Syrian city on the Orontes founded 300 BCE by Seleucus I Nicator; Seleucid and Roman provincial capital, repeatedly destroyed by earthquakes, later Arab, Byzantine, Crusader, and Ottoman, now in Hatay, Turkey.

Antioch Chalice

The Antioch Chalice is a two-part Byzantine silver vessel of about 500–550 in the Metropolitan Museum of Art, exhibited in 1933 as the Holy Grail.

Antioch College

Antioch College, also called Antioch, is a private liberal arts college in Yellow Springs, Ohio, founded 1852 under Horace Mann, pioneer of co-op work education, closed 2008, reopened independently 2011, separate from Antioch University.

Antioch of Pisidia

Antioch of Pisidia (Pisidian Antioch, Colonia Caesarea) was a Seleucid-founded city near Yalvaç, Turkey, refounded by Augustus in 25 BC as the leading Roman veteran colony of the eastern empire, visited by Paul, and flourishing into the 6th century AD.
