Vapor bubbling of intermediate liquid cellulose produces aerosols, which consist of short chain anhydro-oligomers derived from the melt. Continuing decomposition of molten cellulose produces volatile compounds including levoglucosan, furans, pyrans, light oxygenates and gases via primary reactions. Within thick cellulose samples, volatile compounds such as levoglucosan undergo ‘secondary reactions’ to volatile products including pyrans and light oxygenates such as glycolaldehyde.

In the U.S. it has been used in gasoline at low levels since 1979, replacing tetraethyllead (TEL) as an antiknock (octane rating) additive to prevent engine knocking. Oxygenates also help gasoline burn more completely, reducing tailpipe emissions and dilute or displace gasoline components such as aromatics (e.g., benzene). Before the introduction of other oxygenates and octane enhancers, refiners chose MTBE for its blending characteristics and low cost.

Wang W.M., Yang Y.N., Zhang J.Y., Applied Catalysis A. (1995), 133, 1, 81–93 and the catalytic combustion of organic compounds.Catalytic combustion of C3 hydrocarbons and oxygenates over Mn3O4.

MTBE is used as a fuel component in fuel for gasoline engines. It is one of a group of chemicals commonly known as oxygenates because they raise the oxygen content of gasoline.

Gasoline additives increase gasoline's octane rating or act as corrosion inhibitors or lubricants, thus allowing the use of higher compression ratios for greater efficiency and power. Types of additives include metal deactivators, corrosion inhibitors, oxygenates and antioxidants. Some additives are harmful and are regulated or banned in some countries.

The most flexibility is achieved by AR-AFFF or AR-FFFP. AR-AFFF must be used in areas where gasolines are blended with oxygenates, since the alcohols prevent the formation of the film between the FFFP foam and the gasoline, breaking down the foam, rendering the FFFP foam virtually useless.

Using a bone saw, the sternum is cut down the middle. Rib spreaders are inserted in the cut, and spread the ribs to give access to the heart and lungs of the patient. The patient is connected to a heart–lung machine, which circulates and oxygenates blood. The surgeon removes the failing heart and lungs.

Subsequently, molecular oxygen binds end-on to Fe cis to the two donors of the αKG. The uncoordinated end of the superoxide ligand attacks the keto carbon, inducing release of CO2 and forming an Fe(IV)-oxo intermediate. This Fe=O center then oxygenates the substrate by an oxygen rebound mechanism. Alternative mechanisms have failed to gain support.

Walruses feed by digging their muzzles into the sediment and extracting clams through powerful suction. By digging through the sediment, walruses rapidly release large amounts of organic material and nutrients, especially ammonium, from the sediment to the water column. Additionally, walrus feeding behavior mixes and oxygenates the sediment and creates pits in the sediment which serve as new habitat structures for invertebrate larvae.

It appears that only one NMA based product for use as an octane enhancer is registered with ECHA / REACH. Because it is not an oxygenate this component does not appear on the list of recommended oxygenates in European Union (EU) petrol standards. Referring to EU EN 228:2012 and Directive 2009/30/EC, Automotive Fuels of Unleaded Petrol. Requirements and Test Methods.

As the oxygen is present in crude oil at rather low levels, of the order of 0.5%, deoxygenation in petroleum refining is not of much concern, and no catalysts are specifically formulated for oxygenates hydrotreating. Hence, one of the critical technical challenges to make the hydrodeoxygenation of algae oil process economically feasible is related to the research and development of effective catalysts.

Treatment aims to prevent respiratory failure and to ensure adequate blood oxygenation. Supplemental oxygen can be given and it may be warmed and humidified. When the contusion does not respond to other treatments, extracorporeal membranous oxygenation may be used, pumping blood from the body into a machine that oxygenates it and removes carbon dioxide prior to pumping it back in.

The oxygenated blood from the heart leads to the aorta, to sinuses where it oxygenates tissues. Deoxygenated blood goes to efferent branchial vessels in cerata. These efferent vessels can be seen in a transverse section of the cerata as widish canal to pass up the opposite margin. From efferent vessels the blood goes into afferent vessel, where is gets an oxygen.

C. submersum is often used in aquariums as a way to decrease nitrogen in artificial aquatic systems. However, it is not as common in usage as the C. demersum. It is propagated by cutting the stem of the plant and placing it in the aquatic system. After the organic matter is converted to soluble inorganic matter the C. submersum helps to oxygenates waste water.

Threespot damselfish feed mainly on seaweed, but also eat copepods, gastropod molluscs and their eggs, hydroids, marine worms, and sponges. Adults vigorously maintain large territories, chasing away and nipping intruders, including humans. A male and female will form a breeding pair. The female lays eggs which stick to objects on the seabed, and the male guards these and oxygenates them by fanning them with its fins.

During the breeding season, male three-spined sticklebacks defend nesting territories. Males attract females to spawn in their nests and defend their breeding territory from intruders and predators. After spawning, the female leaves the male's territory and the male is solely responsible for the care of the eggs. During the ~6-day incubation period, the male 'fans' (oxygenates) the eggs, removes rotten eggs and debris, and defends the territory.

Extracorporeal membrane oxygenation is generally used for longer-term treatment. CPB mechanically circulates and oxygenates blood for the body while bypassing the heart and lungs. It uses a heart–lung machine to maintain perfusion to other body organs and tissues while the surgeon works in a bloodless surgical field. The surgeon places a cannula in the right atrium, vena cava, or femoral vein to withdraw blood from the body.

Rodewald's open-air naturally filtered pool in high summer. The centrally located outdoor swimming pool is open during the weekends of summer months. It is considered eco-friendly due to the utilisation of aquatic plants and haydite, a rock to which friendly bacteria attach, acting as biological cleansers. Its own waterfall, aside providing a base for those who wish to jump into the water from a height, oxygenates the pool and acts as a return.

Oxygenate blending adds oxygen-bearing compounds such as MTBE, ETBE, TAME, TAEE, ethanol and biobutanol. The presence of these oxygenates reduces the amount of carbon monoxide and unburned fuel in the exhaust. In many areas throughout the U.S., oxygenate blending is mandated by EPA regulations to reduce smog and other airborne pollutants. For example, in Southern California, fuel must contain 2% oxygen by weight, resulting in a mixture of 5.6% ethanol in gasoline.

Mixing cleaning products containing bleach or other oxygenates (such as Comet) with products that contain ammonia or acid is dangerous. The P&G; Comet MSDS specifically warns to: "Avoid contact with acids and ammonia." Despite being labeled as "scratch free", the label for Comet cleanser also advises the use of plenty of water on "delicate surfaces". Comet powdered cleanser is not recommended for use on silver, painted surfaces, walls, soft plastic, aluminum, and rubber.

Sewage liquor is run into deep tanks with diffuser grid aeration systems that are attached to the floor. These are like the diffused airstone used in tropical fish tanks but on a much larger scale. Air is pumped through the blocks and the curtain of bubbles formed both oxygenates the liquor and also provides the necessary mixing action. Where capacity is limited or the sewage is unusually strong or difficult to treat, oxygen may be used instead of air.

Compared with conventional unleaded gasoline, ethanol is a particulate-free burning fuel source that combusts with oxygen to form carbon dioxide, carbon monoxide, water and aldehydes. The Clean Air Act requires the addition of oxygenates to reduce carbon monoxide emissions in the United States. The additive MTBE is currently being phased out due to ground water contamination, hence ethanol becomes an attractive alternative additive. Current production methods include air pollution from the manufacturer of macronutrient fertilizers such as ammonia.

Not all of the fuel is completely consumed by the combustion process. A small amount of fuel is present after combustion, and some of it reacts to form oxygenates, such as formaldehyde or acetaldehyde, or hydrocarbons not originally present in the input fuel mixture. Incomplete combustion usually results from insufficient oxygen to achieve the perfect stoichiometric ratio. The flame is "quenched" by the relatively cool cylinder walls, leaving behind unreacted fuel that is expelled with the exhaust.

Rib spreaders are inserted in the cut, and spread the ribs to give access to the heart and lungs of the patient. The patient is connected to a heart-lung machine, which circulates and oxygenates blood. The surgeon removes the failing heart and lungs. Most surgeons endeavour to cut blood vessels as close as possible to the heart to leave room for trimming, especially if the donor heart is of a different size than the original organ.

Approximately 68% of this production occurs in New South Wales, at a single production facility in Nowra. Ethanol in its pure form can be used as a fuel for vehicles, but like biodiesel, it is usually mixed with petroleum to produce a blended motor fuel. By blending ethanol and petroleum it oxygenates the fuel mixture, meaning it will burn more completely, thus reducing the amount of harmful emissions. Ethanol fuel blends are available in a number of different blend levels.

High-percentage additives are organic compounds that do not contain metals, but require much higher blending ratios, such as 20–30% for benzene and ethanol. It had been established by 1921 that ethanol was an effective antiknock agent, but TEL was introduced instead mainly for commercial reasons. Oxygenates such as TAME derived from natural gas, MTBE made from methanol, and ethanol-derived ETBE, have largely supplanted TEL. MTBE has environmental risks of its own and there are also bans on its use.

The operation of the FID is based on the detection of ions formed during combustion of organic compounds in a hydrogen flame. The generation of these ions is proportional to the concentration of organic species in the sample gas stream. FID measurements are usually reported as "as methane", meaning as the quantity of methane which would produce the same response. Hydrocarbons generally have molar response factors that are equal to the number of carbon atoms in their molecule, while oxygenates and other species that contain heteroatoms tend to have a lower response factor.

Neuromodulators, such as NE, SP, or 5-HT to name a few, can induce nonpacemaker bursting. Although the contributions of the nonpacemaker and pacemaker neurons are a gradient, they differ in their contribution when switching from eupneic to gasping activity. Eupneic activity requires the activation of ICAN and INaP-dependent bursting mechanisms, pacemaker neurons that on ICAN currents selectively hyperpolarize during low oxygenates states, meaning the system depend more so on INaP currents during gasping. The generation of sighs is more sensitive to INaP changes, therefore it may rely somewhat on pacemaker neuron contribution.

In 1965, he joined the Chemical Engineering Department at the University of Minnesota as an assistant professor in the Department of Chemical Engineering and Materials Science. Schmidt's research focused on various aspects of the chemistry and engineering of chemical reactions on solid surfaces. Reaction systems of recent interest are catalytic combustion processes to produce products such as syngas, olefins, and oxygenates by partial oxidation, NOx removal, and incineration by total oxidation. One topic of his research is the characterization of adsorption and reactions on well-defined single-crystal surfaces.

Because it is not an oxygenate NMA does not appear on the list of recommended oxygenates under category 4 of the Worldwide Fuel Charter published by the European Automobile Manufacturers Association (ACEA), which refers to emission standards for unleaded gasoline for “markets with advanced requirements for emission control.” Under policies that are specific to those countries NMA is banned in China and Russia. Most other countries follow the environmental rules of registration of the United States and Europe for the use of this component as an octane enhancer in gasoline / petrol.

In some groups, these two vessels arise directly from the heart, so that the animal may be said to have two aortas. These two vessels in turn divide into many finer vessels throughout the body, and deliver haemolymph to open arterial sinuses where it bathes and oxygenates the tissues. De-oxygenated haemolymph drains into a large venous sinus within the head and foot, which contains the nephridium, an excretory organ with a function similar to that of the vertebrate kidney. From here it passes into vessels within the gill, or into the capillary network of the pulmonate lung, before returning to the heart.

HTE claims the Chi Machine oxygenates the body via "passive aerobic exercise", activating the lymphatic system, enabling detoxification, and aligns the spine due to the figure of eight motion caused by the specific oscillation of the machine. Other devices adopting the same principle have been developed. There is some controversy about the comparison between these similar device and the Sun Ancon Chi Machine distributed by HTE. Many of HTE's distributors claim that any variance from the unique specification of the original Chi Machine - 140 oscillations per minute, +/- 5 - will result in a swinging motion of the body that may negatively affect efficacy or may be harmful.

Simplified C2 cycle Simplified photorespiration and Calvin cycle Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C2 photosynthesis) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis. The desired reaction is the addition of carbon dioxide to RuBP (carboxylation), a key step in the Calvin–Benson cycle, but approximately 25% of reactions by RuBisCO instead add oxygen to RuBP (oxygenation), creating a product that cannot be used within the Calvin–Benson cycle. This process reduces the efficiency of photosynthesis, potentially reducing photosynthetic output by 25% in plants. Photorespiration involves a complex network of enzyme reactions that exchange metabolites between chloroplasts, leaf peroxisomes and mitochondria.

In the United States, the Environmental Protection Agency had authority to mandate that minimum proportions of oxygenates be added to automotive gasoline on regional and seasonal basis from 1992 until 2006 in an attempt to reduce air pollution, in particular ground-level ozone and smog. In addition to this North American automakers have in 2006 and 2007 promoted a blend of 85% ethanol and 15% gasoline, marketed as E85, and their flex-fuel vehicles, e.g. GM's Live Green, Go Yellow campaign. U.S. Corporate Average Fuel Economy (CAFE) standards give an artificial 54% fuel efficiency bonus to vehicles capable of running on 85% alcohol blends over vehicles not adapted to run on 85% alcohol blends.

Flame ionization detectors cannot detect inorganic substances and some highly oxygenated or functionalized species like infrared and laser technology can. In some systems, CO and CO2 can be detected in the FID using a methanizer, which is a bed of Ni catalyst that reduces CO and CO2 to methane, which can be in turn detected by the FID. The methanizer is limited by its inability to reduce compounds other than CO and CO2 and its tendency to be poisoned by a number of chemicals commonly found in gas chromatography effluents. Another important disadvantage is that the FID flame oxidizes all oxidizable compounds that pass through it; all hydrocarbons and oxygenates are oxidized to carbon dioxide and water and other heteroatoms are oxidized according to thermodynamics.

Flavin-containing monooxygenase 3 (FMO3), also known as dimethylaniline monooxygenase [N-oxide-forming] 3 and trimethylamine monooxygenase, is a flavoprotein enzyme () that in humans is encoded by the FMO3 gene. This enzyme catalyzes the following chemical reaction: :trimethylamine + NADPH + H+ \+ O2 \rightleftharpoons trimethylamine N-oxide + NADP+ \+ H2O FMO3 is the main flavin-containing monooxygenase isoenzyme that is expressed in the liver of adult humans. The human FMO3 enzyme catalyzes several types of reactions, including: the of primary, secondary, and tertiary amines; the of nucleophilic sulfur-containing compounds; and the of DMXAA. FMO3 is the primary enzyme in humans which catalyzes the N-oxidation of trimethylamine into trimethylamine N-oxide; FMO1 also N-oxygenates trimethylamine, but to a much lesser extent than FMO3.

Schmidt's research since the early 1990s has focused on the catalytic partial oxidation of alkanes (particularly methane) and oxygenates in continuous flow fixed bed supported catalyst reactors. In 2004, Schmidt and his graduate students demonstrated that biomass-derived ethanol could be converted to molecular hydrogen for fuel cell at greater than 100% selectivity. The significant potential of this discovery has been well- described: > There is, however, a better way of storing the hydrogen needed for fuel > cells: in ethanol, each molecule of which bundles six hydrogen atoms, two > carbon atoms, and one oxygen atom into a package far more compact than > gaseous hydrogen. Until recently, no one could figure out how to unbundle > the ethanol molecules in an energy-efficient way.

The color blood red is a dark shade of the color red meant to resemble the color of human blood (which is composed of oxygenated red erythrocytes, white leukocytes, and yellow blood plasma) by cinnabar, a quick silver thermometer analogue display. It is the iron in hemoglobin specifically that gives blood its red color. The actual color ranges from crimson to a dark brown-blood depending on how oxygenated the blood is, and may have a slightly orange hue. Deoxygenated blood, which circulates closer to the body's surface and which is therefore generally more likely to be seen than oxygenated blood, issues from bodily veins in a dark red state, but quickly oxygenates upon exposure to air, turning a brighter shade of red.

ALOX12B oxygenates arachidonic acid by adding molecular oxygen (O2) in the form of a hydroperoxyl (HO2) residue to its 12th carbon thereby forming 12(R)-hydroperoxy-5Z,8Z,10E,14Z-icosatetraenoic acid (also termed 12(R)-HpETE or 12R-HpETE). When formed in cells, 12R-HpETE may be quickly reduced to its hydroxyl analog (OH), 12(R)-hydroxy-5'Z,8Z,10E,14Z-eicosatetraenoic acid (also termed 12(R)-HETE or 12R-HETE), by ubiquitous peroxidase-type enzymes. These sequential metabolic reactions are: arachidonic acid + O2 \rightleftharpoons 12R-HpETE → 12R-HETE 12R-HETE stimulates animal and human neutrophil chemotaxis and other responses in vitro and is able to elicit inflammatory responses when injected into the skin of an animal model However, the production of 12R-HETE for this or other purposes may not be primary function of ALOX12B. ALOX12B is also capable of metabolizing free linoleic acid to 9(R)-hydroperoxy-10(E),12(Z)-octadecadienoic acid (9R-HpODE) which is also rapidly converted to its hydroxyl derivative, 9-Hydroxyoctadecadienoic acid (9R-HODE).

On February 14, three days after the first round of qualifying, David Hyder, the crew chief for Michael Waltrip and Bobby Kennedy, competition director for Michael Waltrip Racing (MWR) (cars #44 and #55) and Waltrip-PPI Racing (#00) were ejected from the track by NASCAR officials. Earlier, the intake manifold from Waltrip's #55 car had been confiscated by NASCAR when "an unknown substance" was found in it during post-qualifying inspection. When a new manifold was installed and the engine test-run, the same substance was found in the new manifold, resulting in NASCAR impounding the entire car and disallowing Waltrip's qualifying time, which was 25th-fastest. Just before 6 PM US EST, NASCAR held a press conference at which it was announced that both Hyder and Kennedy were suspended indefinitely, Hyder fined $100,000, Waltrip docked 100 championship points, and the team, owned by Waltrip's wife, Buffy, were docked 100 car owner points for violations that included a violation of the rule (in place through the 2010 season) prohibiting the blending of gasoline with "alcohols, ethers, or other oxygenates"; this quickly became known among the media and fans as "rocket fuel".
