Flux method
The flux method grows single crystals by dissolving a compound's components in a molten solvent called a flux and cooling, so crystals form below the compound's melting point.
Flux pinning
Flux pinning, also known as quantum locking, is the immobilization of quantized magnetic flux lines in a type-II superconductor by material defects, which lets it carry large currents without resistance.
Flux quantization
Flux quantization is the restriction of magnetic flux through a multiply connected superconductor, such as a ring, to integer multiples of the quantum h/2e, first observed in 1961.
Flux quantum
The flux quantum (Φ0) is the natural unit of magnetic flux in superconductivity, equal to h/2e and exact since the 2019 SI revision fixed h and e.
Flux qubit
A flux qubit is a superconducting quantum bit whose two states are persistent currents circulating in opposite directions around a loop interrupted by Josephson junctions.
Flux reconstruction
Flux reconstruction, also called CPR, is a high-order numerical method for solving conservation laws such as the compressible Navier-Stokes equations on unstructured grids, unifying DG, SV, and SD schemes.
Flux rope
A flux rope is a bundle of magnetic field lines twisted into a helix around a central axis, central to many solar eruptions and coronal mass ejections.
Flux tower
A flux tower is an instrumented tower or mast erected in an ecosystem to measure gas, heat, and momentum exchange with the atmosphere, usually by eddy covariance.
Flux tube (physics)
A flux tube in physics is a narrow tube of chromo-electric field connecting a quark and antiquark, whose energy grows linearly with separation, explaining quark confinement.
Flux-closure domain
A flux-closure domain is a topological domain structure in ferroelectrics in which polarization vectors rotate around a core so electric flux closes, avoiding surface charge buildup.
Flux-cored arc welding
Flux-cored arc welding (FCAW) is a semiautomatic arc welding process that joins metals with a continuously fed tubular flux-cored wire, widely used in structural fabrication, construction, and shipbuilding.
FLUX.1
FLUX.1 is a family of 12-billion-parameter text-to-image models released by Black Forest Labs in 2024, with Pro available by API, Dev open-weight for non-commercial use, and Schnell under Apache 2.0.
FLUX.2
FLUX.2 is a text-to-image generation and editing model family released by Black Forest Labs in November 2025, with an open-weight 32 billion parameter [dev] checkpoint.
Fluxà Rosselló family
The Fluxà Rosselló family (Fluxà Roselló family) is a Spanish business family from Mallorca that owns the Iberostar hotel group and the Camper and Lottusse footwear brands.
Fluxapyroxad
Fluxapyroxad (BAS 700 F) is a BASF pyrazole-carboxamide SDHI fungicide, FRAC group 7, approved in the EU on 1 January 2013 and in the US in 2012, with EU approval extended to 31 October 2027.
Fluxer
Fluxer is a free and open-source instant messaging and VoIP chat app for communities, developed by Swedish company Fluxer Platform AB and self-hostable as an alternative to Discord.
Fluxgate magnetometer
A fluxgate magnetometer is a vector instrument measuring DC and low-frequency magnetic fields via a saturating ferromagnetic core, invented in 1936 and used from space missions to submarine detection.
Fluxional molecule
A fluxional molecule undergoes rapid, reversible intramolecular rearrangements among two or more equivalent structures, fast enough to detect by NMR spectroscopy; bullvalene and PF5 are classic examples.
FLUXNET
FLUXNET is an international "network of networks" that harmonizes eddy covariance measurements of carbon, water, and energy fluxes from regional networks at over 1,000 sites worldwide.
Fluxonium qubit
A fluxonium qubit is a superconducting artificial atom in which a small Josephson junction is shunted by a superinductor, introduced in 2009 at Yale University and prized for low charge-noise sensitivity.
Fluxus
Fluxus: international avant-garde art movement founded by George Maciunas, active early 1960s to 1978, integrating art and life through event scores, fluxkits, festivals, and multiples.
Fluy
Fluy, a village in the Somme, France, is the site of a vast Gallo-Roman rural sanctuary of the Ambiani in Gallia Belgica, where aerial photography revealed a temple with arcaded enclosure and a theatre known only from the air.
Fluyt
The fluyt, also spelled fluit (Dutch: fluitschip), is a Dutch cargo sailing ship developed in the late 16th century, mainstay of Dutch Baltic trade for 200 years.
