Aluminum back surface field
An aluminum back surface field (Al-BSF) is a heavily aluminum-doped layer formed on the rear of a p-type silicon solar cell to suppress electron recombination at the metal contact.
Aluminum Corp of China
Aluminum Corp of China, known as Chalco, is the listed aluminum producer of China's state group Chinalco, founded in 2001 and by its own account the world's largest alumina supplier.
Aluminum fluoride
Aluminum fluoride (AlF₃) is an inorganic compound of aluminum and fluorine, appearing as white crystals and used chiefly to adjust the cryolite electrolyte in the Hall-Héroult cells that smelt aluminum.
Aluminum formate
Aluminum formate, Al(HCOO)₃, is one of the simplest metal-organic frameworks, a low-cost adsorbent that selectively captures carbon dioxide from flue gas and regenerates at about 80 °C.
Aluminum honeycomb
Aluminum honeycomb is a lightweight core material of hexagonal cells made from thin aluminum foil, bonded between face sheets in sandwich panels used widely in aircraft, spacecraft, and crash-absorbing structures.
Aluminum Monostearate
Aluminum monostearate (dihydroxy(stearato)aluminum) is an aluminum soap, the aluminum salt of stearic acid, used mainly as a pharmaceutical excipient that gels oily injectable vehicles and as a cosmetic colorant and viscosity agent.
Aluminum nitride
Aluminum nitride (AlN) is a hard, covalently bonded ceramic of aluminum and nitrogen, first synthesized in 1877 and used since the mid-1980s as an electrically insulating, heat-conducting substrate in microelectronics.
Aluminum nitride substrate
An aluminum nitride substrate is a wafer or ceramic plate of aluminum nitride (AlN), a wide-bandgap semiconductor prized for its high thermal conductivity in power and deep-UV devices.
Aluminum Phosphate
Aluminum phosphate (AlPO₄) is a water-insoluble inorganic salt of aluminum and phosphoric acid, used in baking powders, as a vaccine adjuvant, and as a molecular sieve.
Aluminum Phosphide
Aluminum phosphide (AlP) is an inorganic compound that reacts with moisture to release toxic phosphine gas, used since the 1940s as the dominant fumigant for stored grain.
Aluminum plasmonics
Aluminum plasmonics uses aluminum nanostructures to support surface plasmons resonant into the ultraviolet, where standard plasmonic metals gold and silver perform poorly, enabling UV sensing and photocatalysis.
Aluminum scandium nitride
Aluminum scandium nitride (AlScN) is a wurtzite III-nitride semiconductor alloy of AlN and scandium, ferroelectric above 30 percent Sc and used in 5G RF filters and memory.
Aluminum sulfate
Aluminum sulfate, commonly called alum or filter alum, is a water-soluble aluminum salt used chiefly as a coagulant in water treatment and historically in paper sizing, where it acidified paper.
Aluminum-activated malate transporter
Aluminum-activated malate transporters (ALMTs), founder TaALMT1, are plant anion-channel proteins, not true transporters, mediating malate efflux for aluminum tolerance, plus stomatal function, fruit acidity, and GABA transport.
Aluminum-air battery
The aluminum-air battery, or Al-air battery, is a primary metal-air electrochemical cell that generates electricity by oxidizing an aluminum anode while drawing oxygen from surrounding air.
Aluminum-ion battery
An aluminum-ion battery is a rechargeable battery that uses a metallic aluminum anode with chloride-based electrolytes, promising high capacity and safety but not yet commercially viable.
Aluminum–sulfur battery
An aluminum–sulfur battery (Al–S battery) is a rechargeable battery pairing an aluminum anode with a sulfur cathode, typically in molten salt or ionic liquid electrolytes.
Aluminylene
An aluminylene is a neutral low-valent compound of aluminum in the +1 oxidation state, the heavier group 13 analog of a carbene, with a two-coordinate aluminum center.
Alumis Inc.
Alumis Inc. is a South San Francisco biopharmaceutical company, public on Nasdaq since 2024, whose lead drug envudeucitinib showed positive Phase 3 psoriasis results in 2026.
Alun
Alun: name of two villages in Hunedoara County, Romania, one with a Roman iron mine and marble quarry in the Poiana Ruscă Mountains, the other at the Dacian fortress of Piatra Roșie; also a Pembrokeshire river and a Welsh lead mine.
Alun Armstrong
Alun Armstrong (born Robert Alun Armstrong, 1946) is an English character actor, not to be confused with the astronaut Neil Armstrong or unrelated Armstrong companies. Known for nine years with the Royal Shakespeare Company, Thénardier in the original 1985 London Les Misérables, an Olivier Award for Sweeney Todd, Brian Lane in New Tricks (2003–2013), and roles in Get Carter, The Mummy Returns, Van Helsing, and The Choral (2025).
Alun Millward Davies
Alun Millward Davies, publishing as Alun M. Davies, is a developmental neuroscientist at Cardiff University known for work on neurotrophic factors and nerve cell survival.
Alun Wyn Jones
Alun Wyn Jones (born 1985, Swansea) is a Welsh former rugby union second row and the most capped international rugby player, with a world-record 170 caps (158 Wales, 12 British and Irish Lions), five Six Nations titles including three Grand Slams, and four Lions tours.
