Anthracite
Anthracite, also called hard coal, is the highest rank of coal, hard and lustrous with about 80 percent fixed carbon, mined mostly in northeastern Pennsylvania.
Anti-perovskite lithium-ion conductors
Anti-perovskite lithium-ion conductors are lithium-rich solid electrolytes with a perovskite-inverted structure, typified by Li₃OCl, valued for high ionic conductivity, stability against lithium metal, and use in all-solid-state batteries.
Anti-perovskite solid electrolyte
An anti-perovskite solid electrolyte is a crystalline ionic conductor, built mainly from lithium, oxygen, and chlorine or bromine, in which ions occupy inverted perovskite lattice positions; the prototype is Li₃OCl.
Anti-soiling coating
An anti-soiling coating is a thin functional layer applied to solar module glass, mirrors, or heliostats to reduce dust accumulation, since soiling can cut efficiency by up to 34%.
Anti-solvent dripping processing for perovskite solar cells
Anti-solvent dripping is a film-formation step for perovskite solar cells, introduced in 2014, in which a poor solvent dripped during spin coating triggers rapid crystallization.
Anticipated transient without scram
An anticipated transient without scram (ATWS) is a nuclear reactor accident sequence in which the reactor fails to shut down automatically during an anticipated transient.
Antilag system
The antilag system, also known as a misfiring system, keeps a turbocharged engine's turbo spinning during throttle lifts, used almost exclusively in motorsport like rallying.
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/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.
