The overall process is called nitrogen fixation.

It is the spectrum of a planet like Earth, showing a presence of nitrogen dioxide, as a clear signal of life, and oxygen and ozone.

Other degrading solutions are sulfur dioxide in water and carbon dioxide in water.

The atmosphere mostly consists of nitrogen and oxygen.

The air mainly consists of oxygen and nitrogen.

Air is mainly composed of nitrogen and oxygen.

Too much nitrogen is just as harmful as too little.

The air we breathe consists of oxygen and nitrogen.

The largest, Triton, is geologically active, with geysers of liquid nitrogen.

Significant amounts of nitrogen and carbon may have been present in the form of carbon monoxide (CO) and molecular nitrogen (N2) instead of ammonia and methane.

Trees use photosynthesis to turn sunlight, carbon dioxide and water into sugars.

We're all breathing air right now. Air is a mixture of oxygen and nitrogen, about 20 percent oxygen. About 80 percent nitrogen is in our lungs.

Only 60 years later, the French scientist Eugène Melchior Péligot identified it with uranium oxide.

Mars has a very thin atmosphere made of carbon dioxide, nitrogen, and argon.

And if we see the nitrogen dioxide I think we have the perfect E.T.

But the nitrogen oxides that diesel engines emit are considered carcinogens, and can cause asthma.

Reaction of uranium(VI) oxide with hydrogen results in uranium dioxide, which is similar in its properties with ThO2.

Likewise, more nitrogen fertilizer is applied in agriculture than is fixed naturally in all terrestrial ecosystems, and nitric oxide production from the burning of fossil fuels and biomass also surpasses natural emissions.

Reduction with hydrogen gives UO2, which is converted with hydrofluoric acid (HF) to uranium tetrafluoride, UF4.

You need the bacteria to fix nitrogen, and without those microorganisms, you won't have any performance at all.

Reductions of other greenhouse gases, such as nitric oxide, are attainable through clever combustor design.

It was initially assumed that the alkaloids are the final products of nitrogen metabolism in plants, as urea in mammals.

Nitric oxide is then released from the macrophage and, because of its toxicity, kills microbes near the macrophage.

While there is little or no water on Venus, there is a phenomenon which is quite similar to snow.

Nitrogen(I) and bismuth(I) are known but rare and ununpentium(I) is likely to show some unique properties, probably behaving more like thallium(I) than bismuth(I).

About 99 of a mammal's mass is made up of the elements carbon, nitrogen, calcium, sodium, chlorine, potassium, hydrogen, phosphorus, oxygen and sulfur.

The relative lack of nitrogen ice suggests that its supply of nitrogen has somehow been depleted over the age of the Solar System.

We've been able to engineer viruses to pick up carbon nanotubes and then grow titanium dioxide around them and use as a way of getting electrons through the device.

The drug, BiDil, is designed to treat or prevent congestive heart failure by raising low or depleted levels of nitric oxide in the blood. It was originally designed for a wide population base, and race was irrelevant.

Reserves of minerals like phosphate will remain plentiful in the next decades, and nitrogen is not limited.

The drug, BiDil, is designed to treat or prevent congestive heart failure by raising low or depleted levels of nitric oxide in the blood.

Organic compounds (proteins, lipids and carbohydrates) contain the majority of the carbon and nitrogen most of the oxygen and hydrogen is present as water.

Significant amounts of nitrogen and carbon may have been present in the form of carbon monoxide and N2 instead of ammonia and methane.

Approximately 10 may be used with a slow freeze method, and the cells may be frozen at or stored in liquid nitrogen safely.

Several gases, including carbon dioxide, methane, and nitrous oxide, warm the planet as their concentrations in the atmosphere increase.

When brought to the surface, these nutrients are utilized by phytoplankton, along with dissolved CO2 (carbon dioxide) and light energy from the sun, to produce organic compounds, through the process of photosynthesis.

The heavy particles found in the fumes are composed of more than carbon dioxide there are others particles that his invention will have to fix, in order to achieve a purification rate closer to 100 .

By interfering with the carbon, nitrogen, water, and phosphorus cycles, human activity changes the atmosphere, oceans, waterways, forests, and ice sheets, and diminishes biodiversity.

The nitrogen just sort of floats around in our blood and tissues, and that's all fine, that's how we're designed.

Although atmospheric nitrogen abounds (more than 75 ), few living creatures are capable of using this atmospheric nitrogen in its diatomic form, N2 gas.

If you don t think this work important, consider that half the nitrogen in your body is synthetic, a product of a Haber Bosch factory.

Six elements appear in this table, namely hydrogen, oxygen, nitrogen, carbon, sulfur, and phosphorus, with the atom of hydrogen conventionally assumed to weigh 1.

Confronting the growing challenge means that humanity can no longer afford to ignore the inexhaustible resource found in the organic material that the sun provides each day through photosynthesis. Solar energy enables plants to absorb carbon gas and thereby produce not only oxygen, but also matter that the animal kingdom uses for food and that our machines can use for energy.

When proline is bound as an amide in a peptide bond, its nitrogen is not bound to any hydrogen, meaning it cannot act as a hydrogen bond donor, but can be a hydrogen bond acceptor.
