RedOne

RedOne, born Nadir Khayat (1972, Tétouan, Morocco), is a Moroccan-Swedish producer and songwriter behind Lady Gaga's Just Dance and Poker Face, FIFA's 2006 Bamboo, and founder of 2101 Records.

Redouane Halhal (born 2003, Montpellier) is a Moroccan centre-back at Venezia FC in Serie A, formerly of Montpellier, Atlético Madrid B, Helmond Sport, and KV Mechelen, with five Morocco caps including two 2026 World Cup starts.

Redoubt

A redoubt is a small enclosed fortification, usually an earthwork with a parapet and ditch, defending a position from any direction; unlike a redan, it is closed at the rear.

Redoutable-class submarine (1967)

The Redoutable class was a class of six nuclear-powered ballistic missile submarines built for the French Navy between 1964 and 1985, the first generation of France's sea-based nuclear deterrent.

Redox

Redox (reduction–oxidation) is a chemical reaction in which electrons are transferred: the species losing electrons is oxidized, and the receiver is reduced; the two changes always occur together.

Redox biology

Redox biology studies oxidation–reduction (electron transfer) reactions in living systems, reactive oxygen species signaling, redox homeostasis, and oxidative stress in disease; also the Elsevier open-access journal Redox Biology (ISSN 2213-2317), Q1 since 2013.

Redox imaging

Redox imaging maps the oxidation-reduction state of living cells and tissues, either label-free from the autofluorescence of NADH and FAD, or from genetically encoded redox sensors.

Redox mediators in Li–oxygen batteries

Redox mediators (RMs) in lithium–oxygen batteries are soluble redox-active molecules or ions that shuttle charge between the insulating discharge product lithium peroxide and the electrode, lowering the charge voltage.

Redox non-innocent ligands in electrocatalysis

Redox non-innocent ligands are ligands in metal complexes that share electrons with the metal center, acting as electron and proton reservoirs for multielectron electrocatalytic reactions.

Redox process

The Redox process was a solvent-extraction method for reprocessing irradiated nuclear fuel, developed in 1947 and used at large scale at Hanford in Washington from 1952 until 1966 or 1967.

Redox targeting

Redox targeting is an energy-storage method in which redox mediator molecules shuttle electrons between an electrode and a solid active material not wired to the circuit.

Redox titration

A redox titration is a titration method in which an analyte is measured through an oxidation–reduction reaction with a titrant of known concentration, calculated from the volume consumed at the endpoint.

Redox-active esters

Redox-active esters (RAEs), most commonly N-hydroxyphthalimide (NHPI) esters, are carboxylic acid derivatives that fragment on single-electron reduction to give carbon radicals, letting chemists use abundant carboxylic acids in nickel-catalyzed cross-coupling.

Redox-active organic cathodes

Redox-active organic cathodes are positive electrodes for rechargeable batteries in which charge is stored by organic molecules or polymers rather than cobalt or nickel oxides.

Redox-active polymer flow batteries

Redox-active polymer flow batteries are aqueous organic redox flow batteries storing charge in redox-active polymers, first demonstrated in 2015 with dialysis membranes and a sodium chloride electrolyte.

Redox-relay Heck reaction

The redox-relay Heck reaction is a palladium-catalyzed arylation or alkenylation of alkenyl alcohols in which the catalyst migrates along the chain, oxidizing the alcohol to a carbonyl.

Redox-sensitive transcriptional activator SoxR

SoxR, a MerR-family bacterial transcription factor with [2Fe-2S] clusters, senses redox stress and nitric oxide; oxidation activates soxS and the SoxRS oxidative stress and antibiotic resistance regulon.

Redox-targeting flow battery

A redox-targeting flow battery, also called a redox-mediated or redox-shuttle flow battery, is a redox flow battery that stores most of its energy as solid material held in the tanks.

Redoxcline

A redoxcline is the layer in a lake or basin where redox conditions change sharply with depth, separating oxygenated water above from anoxic water or sediment below.

Redoxin

Redoxins are thioredoxin-fold thiol oxidoreductase proteins, including thioredoxins, glutaredoxins, peroxiredoxins, and NrdH redoxins, which reduce protein disulfides and regulate redox status in archaea, bacteria, and eukaryotes.

RedPajama

RedPajama is a pair of openly licensed pretraining corpora for large language models released by Together AI: a 1.2-trillion-token reproduction of LLaMA's data recipe in 2023, and a 100-billion-document web corpus in 2024.

Redpanda

Redpanda is a Kafka API-compatible streaming data platform written in C++, shipped as a single binary with no ZooKeeper or JVM, using thread-per-core Seastar design, Raft consensus, and BSL-licensed source-available code.

Redpoint (climbing)

Redpoint (Rotpunkt): clean lead ascent of a route after prior attempts, without falling or weighting the rope; coined by Kurt Albert in the 1975 Frankenjura; standard style for hard sport climbs, ranked below flash and onsight.

ReDRagon

reDRagon: ROH tag team of Bobby Fish and Kyle O'Reilly formed in 2012; three-time ROH World Tag Team Champions, two-time IWGP Junior Heavyweight Tag Team Champions, later NXT's Undisputed Era and AEW.

Redrama

Redrama (Lasse Mellberg) is a Finnish rapper who won the Finnish English-language rap championship in 2001 and the Emma award for best hip hop album in 2005.

Redridge Steel Dam

The Redridge Steel Dam is a decommissioned steel gravity dam across the Salmon Trout River in Houghton County, Michigan, built in 1901 to supply water for copper stamp mills.

Redrum

Redrum is the dubstep and bass music project of Tatiana Tindall, a Portland-based producer signed to Liquid Stranger's WAKAAN and SSKWAN imprints and a recurring name on the US festival circuit.

Reds (film)

Reds is a 1981 American historical drama directed, written by, and starring Warren Beatty, telling of journalist John Reed's love affair with Louise Bryant during the Russian Revolution.

Redshaw Burn

Redshaw Burn: small Roman fortlet in Crawford parish, South Lanarkshire, Scotland, beside the Carlisle-to-Forth Roman road; discovered from the air in 1939, occupied 2nd/3rd centuries AD, scheduled monument SM3348.
