Oxford Instruments
Oxford Instruments is a British supplier of high-technology scientific instruments, headquartered in High Wycombe. Founded in 1959 by Sir Martin and Lady Audrey Wood, it began with superconducting magnets.
Oxford Ionics
Oxford Ionics is a British quantum computing company founded in 2019 by Oxford physicists Chris Ballance and Tom Harty that builds trapped-ion quantum computers controlled electronically on silicon chips.
Oxford RobotCar Dataset
The Oxford RobotCar Dataset is an autonomous driving dataset of over 100 traversals of a roughly 10 km route through Oxford, UK, captured from 2014 to 2015.
Oxford Robotics Institute
The Oxford Robotics Institute (ORI) is a robotics and artificial intelligence research institute of the University of Oxford, founded in 2016 within the Department of Engineering Science.
Oxford Street
Oxford Street, historically the Tyburn Road, is a major retail street in London's West End, running 1.2 miles from Marble Arch to Tottenham Court Road and home to Selfridges, John Lewis, and Marks & Spencer.
Oxiacaque Oil and Gas Field
Oxiacaque is an operating onshore oil and gas field in Tabasco, Mexico, discovered in 1977 and operated by Pemex, producing medium sour crude from a fractured carbonate reservoir.
OxiClean
OxiClean is an American brand of oxygen-based cleaning products, best known for its Versatile Stain Remover, a sodium percarbonate powder owned by Church & Dwight since 2006.
Oxidation ditch
An oxidation ditch is a modified activated-sludge process that treats wastewater in a racetrack-shaped loop, using rotating aerators and long solids retention times to remove organic matter and nutrients.
Oxidation of Metals
Oxidation of metals is the reaction of a metal or alloy with oxygen or another oxidizing gas to form an oxide film or scale on its surface.
Oxide dispersion strengthened steel
Oxide dispersion strengthened steel (ODS steel) is steel with nanoscale yttria particles dispersed through it, pinning dislocations to keep strength at high temperatures and under neutron irradiation.
Oxide memristors for analog AI
Oxide memristors for analog AI are two-terminal resistive-switching devices, typically built from oxides such as TaOx and HfOx, whose oxygen-vacancy motion gives gradual conductance used as synaptic weights in neuromorphic computing.
Oxide retinomorphic sensor
An oxide retinomorphic sensor is an image sensor built from oxide semiconductors like ITO and indium oxide, where each pixel both senses light and computes, mimicking the retina.
Oxide semiconductor synaptic transistors
Oxide semiconductor synaptic transistors are three-terminal thin-film devices, usually with an amorphous IGZO channel, whose conductance changes emulate biological synapse weight updates, built for low-power neuromorphic computing hardware.
Oxide semiconductor TFT backplane
An oxide semiconductor TFT backplane is a flat-panel display backplane whose thin-film transistors use an oxide semiconductor, most commonly indium-gallium-zinc-oxide (IGZO), offering high mobility, low leakage, and low power for OLED, LCD, and Micro-LED displays.
Oxide thermoelectric modules
Oxide thermoelectric modules are solid-state devices that convert heat into electricity using ceramic oxides, operating in air at high temperature where bismuth telluride modules fail.
Oxy-fuel welding and cutting
Oxy-fuel welding and cutting, also known as oxyacetylene welding or flame cutting, burns a fuel gas such as acetylene with pure oxygen to weld or cut steel.
Oxygen balance
Oxygen balance measures how well an explosive's own oxygen matches what is needed to oxidize its fuel fully, expressed as excess or deficit, negative for TNT.
Oxygen concentrator
An oxygen concentrator, or PSA oxygen generator, is a medical device that concentrates oxygen from air using pressure swing adsorption, delivering 90–93% oxygen for therapy.
Oxygen delignification
Oxygen delignification, also called oxygen bleaching or the O stage, is a pulp and paper process that removes residual lignin from kraft pulp before bleaching.
Oxygen Generation System
The Oxygen Generation System (OGS) is the International Space Station's primary source of breathable oxygen, electrolyzing reclaimed water in a 28-cell stack and running nearly continuously since 2007.
Oxygen mask
An oxygen mask is a face covering connected to an oxygen supply that delivers supplemental oxygen, used in medicine for patients and in aviation for low cabin air oxygen.
Oxygen plasma etching
Oxygen plasma etching is a dry process that removes organic materials such as photoresist and polymers, converting them into volatile gases pumped away, chiefly in microfabrication.
Oxygen precipitation
Oxygen precipitation is the formation of silicon dioxide particles from dissolved oxygen in Czochralski-grown silicon wafers during annealing, the basis of intrinsic gettering that traps metallic contaminants away from devices.
Oxygen redox instability in Li-rich cathodes
Oxygen redox instability in Li-rich cathodes is the tendency of lithium-rich layered oxide battery cathodes to lose capacity and voltage because oxidized lattice oxygen escapes as O₂.
Oxygen vacancies as OER active sites in perovskites
Oxygen vacancies in perovskite oxides, written ABO3-δ, are missing lattice oxygens that serve as catalytic active sites for the oxygen evolution reaction in water electrolysis and metal-air batteries.
Oxygen-depolarized cathode
An oxygen-depolarized cathode (ODC) is a gas diffusion electrode in chlorine electrolysis that reduces oxygen instead of evolving hydrogen, cutting electricity demand by about 30 percent.
OxygenOS
OxygenOS is an Android-based operating system developed by OnePlus for its smartphones and tablets, known for a fast, stock-like design; in 2026 OnePlus began phasing it out in favor of Oppo's ColorOS.
Oxyhydrogen
Oxyhydrogen, also known as knallgas or Brown's gas, is a 2:1 mixture of hydrogen and oxygen that burns with a very hot flame back to water.
Oyot Oil and Gas Field
The Oyot Oil and Gas Field is an offshore oil and gas field in Nigeria in concession block OML 70, distinct from the similar Oyo field in OML 120.
Oyster card
The Oyster card is a contactless smart ticket used on Transport for London services such as the Tube, buses, and trams, introduced in 2003 and holding pay as you go credit or season tickets.
