Ferrofluid

A ferrofluid is a colloidal liquid of magnetic nanoparticles in a carrier liquid, invented at NASA in the early 1960s and used in seals and loudspeakers.

Ferrofluid mirror

A ferrofluid mirror is an optical mirror whose reflective surface is a magnetic liquid shaped by magnetic fields, used in adaptive optics to correct wavefront aberrations.

Ferroglobe PLC is a UK-incorporated metals company producing silicon metal and silicon- and manganese-based alloys. Formed in 2015 from Grupo FerroAtlántica and Globe Specialty Metals, it trades on Nasdaq as GSM.

Ferroglobus

Ferroglobus, a genus of hyperthermophilic iron-metabolizing archaea in the Archaeoglobaceae; type species F. placidus from Vulcano, Italy, grows at 65–95°C, oxidizes Fe2+, acetate, and aromatics, and does not reduce sulfate.

Ferroin

Ferroin is the tris(1,10-phenanthroline)iron(II) complex used in analytical chemistry as a redox indicator, changing sharply from red to pale blue in titrations with cerium(IV) and dichromate.

Ferromagnetic liquid crystal

A ferromagnetic liquid crystal is a colloidal suspension of ferromagnetic nanoparticles in a nematic liquid crystal with spontaneous magnetization, first realized experimentally by Mertelj and colleagues in 2013.

Ferromagnetic liquid droplets

Ferromagnetic liquid droplets are liquid droplets that carry a permanent magnetization because magnetic nanoparticles jam at the liquid-liquid interface, first demonstrated by Berkeley Lab researchers in 2019.

Ferromagnetic resonance

Ferromagnetic resonance (FMR) is a microwave spectroscopy technique, demonstrated by J. H. E. Griffiths in 1946, that measures absorption in ferromagnets to extract damping, magnetization, and anisotropy.

Ferromagnetism

Ferromagnetism is the strongest form of everyday magnetism: unpaired electron spins align in parallel, producing spontaneous magnetization in elements like iron, cobalt, and nickel below the Curie temperature.

Ferromex

Ferromex (Ferrocarril Mexicano) is a Mexican freight railway company owned by Grupo México, operating Mexico's largest rail system since 1998 as one of two main freight operators.

Ferrone Necropolis

Ferrone Necropolis (Necropoli della Riserva del Ferrone), Etruscan chamber-tomb cemetery in the Tolfa Mountains near Cerveteri, Lazio, Italy; used mid-7th to mid-5th century BC, about 40-50 tombs including the Tomba dei Troni and the only dado tombs of the Tolfa.

ferronickel

Ferronickel (FeNi) is an iron-nickel ferroalloy, typically 20 to 40% nickel, produced from laterite ores by the rotary kiln–electric furnace process and used as a stainless steel raw material.

Ferroplasma

Ferroplasma is a genus of cell wall-lacking, iron-oxidizing archaea (Thermoplasmatales) from acid mine drainage at pH 0–2; type species F. acidiphilum, with 86% iron-metalloproteins.

Ferroportin

Ferroportin-1 (FPN, SLC40A1, IREG1, MTP1) is the only known mammalian cellular iron exporter, regulated by hepcidin, with two metal-binding sites; mutations cause hemochromatosis type 4.

Ferroportin disease

Ferroportin disease, also called hemochromatosis type 4, is an autosomal dominant iron overload disorder from SLC40A1 mutations, causing iron buildup in macrophages with high ferritin.

Ferrotec Holdings Corporation

Ferrotec Holdings Corporation, renamed Ferrotec Corporation in 2025, is a Tokyo-headquartered Japanese materials-technology group founded in 1980 that makes ferrofluid seals, quartz crucibles, ceramics, and thermoelectric modules for semiconductor manufacturing.

Ferrous ammonium phosphate

Ferrous ammonium phosphate (FeNH4PO4, FAP) is an iron salt food fortificant developed by Nestle for sensitive foods like milk and cocoa; GRAS (GRN 271, 2009), JECFA PMTDI 0.8 mg/kg bw, bioavailability between ferrous sulfate and ferric pyrophosphate.

Ferrous bisglycinate

Ferrous bisglycinate (ferrous bis-glycine chelate, FeBC), an iron(II)-glycine amino acid chelate supplement and fortificant; GRAS (GRN 19, 1999); higher bioavailability and fewer GI side effects than iron salts, though clinical superiority is unproven.

Ferrovial

Ferrovial is a Spanish-origin infrastructure group founded in 1952, known for operating toll roads like the 407 ETR and airports, and seated in Amsterdam since 2023.

Ferrovie dello Stato Italiane

Ferrovie dello Stato Italiane, known as FS Italiane or the FS Group, is the Italian state-owned railway holding company founded in 1905, controlling Trenitalia, RFI, and Anas.

Ferruccio Ferragamo

Ferruccio Ferragamo is an Italian fashion executive, eldest son of founder Salvatore Ferragamo, who ran the family luxury house as CEO from 1984 to 2006 and chairman until 2021.

Ferruccio Lamborghini

Ferruccio Lamborghini (1916–1993) was an Italian industrialist who built a tractor fortune from 1948, founded Automobili Lamborghini in 1963, and retired to a wine estate in Umbria.

Ferruginol

Ferruginol is a phenolic abietane diterpenoid with formula C20H30O, first isolated in 1939 from miro resin, characteristic of cypress-family heartwood and studied for antibacterial, antifungal, and antitumor activities.

Ferry

A ferry, or ferry boat, is a vessel that carries passengers, vehicles, or goods across water on a regular schedule, moving about 4.27 billion passengers yearly.

Ferry Corsten (musician)

Ferry Corsten is a Dutch trance DJ and producer from Rotterdam, born in 1973, best known for the 1999 anthem "Out of the Blue" as System F.

Ferry endosomal RAB5 effector complex subunit 3

FERRY3 (C12orf4, Fy-3) is a 552-amino-acid human protein on chromosome 12p13.32, a subunit of the five-subunit FERRY Rab5 effector complex that binds mRNA on early endosomes; its disruption is implicated in autosomal recessive intellectual disability.
