All we are is a lot of talking nitrogen.
Under natural conditions, the soil does not lose its fixed nitrogen.
Agricultural husbandry essentially maintains the balance of bound nitrogen.
We have decisively changed the carbon cycle, the nitrogen cycle, and the rate of extinction.
Growing and decaying vegetation in this land are responsible for 93 percent of the oxides of nitrogen.
Too often, chefs just want to experiment - they want to use liquid nitrogen before they know how to use heat.
Gaseous nitrogen combines with gaseous hydrogen in simple quantitative proportions to produce gaseous ammonia.
Grief is an element. It has its own cycle like the carbon cycle, the nitrogen. It never diminishes not ever. It passes in and out of everything.
I figure I've done what I could do, more or less, and now I'm going back to being a chemical; all we are is a lot of talking nitrogen, you know.
The Swedish Academy of Sciences has seen fit, by awarding the Nobel Prize, to honour the method of producing ammonia from nitrogen and hydrogen.
Nitrogen fertilizer is used on all crops produced in this country, but it is a key plant nutrient to produce corn a critical crop to Illinois farmers.
Carbon's eastern neighbor on the table, nitrogen, dresses up diamonds in pinks, yellows, oranges, and brownish tints known romantically as 'champagne.'
We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive.
All of my dishes kind of have the same thing going on - I'm always going to give you the same things that I grew up with or that my mom used to make. I'm not going to use nitrogen in my tacos.
We're not just any star stuff, most of which is humdrum hydrogen and listless helium. Our bodies include fancier ingredients like carbon, oxygen, nitrogen, phosphorous, and a few other herbs and spices.
The more the relationships of the nitrogen-rich substances to the cell nucleus were recognized, the more the question of the arrangement of the nitrogen and carbon atoms in the molecule came to stand out.
Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organise themselves into a professor of chemistry? What's the motive?
In order to 'go out the door' safely, we go through a pretty thorough process called pre-breathe. This is the process of flushing all the nitrogen out of our systems by breathing higher concentrations of oxygen.
We have an atmosphere that is roughly 21% oxygen. The rest of it is largely nitrogen. There's just enough carbon dioxide (CO2) to drive photosynthesis. That has been, throughout the history of our species, pretty stable. Until recently.
The earth is bountiful, and where her bounty fails, nitrogen drawn from the air will refertilize her womb. I developed a process for this purpose in 1900. It was perfected fourteen years later under the stress of war by German chemists.
Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.
If you look at the ecological circuitry of this planet, the ways in which materials like carbon or sulfur or phosphorous or nitrogen get cycled in ways that makes them available for our biology, the organisms that do the heavy lifting are bacteria.
I've been experimenting more and more with LN2, liquid nitrogen. I've used it in battle on 'Iron Chef America,' but have also made some great ice creams at home for my family. Since it freezes basically on contact, you can have ice cream ready in mere minutes.
The usual way of growing cotton is highly petrochemical-intensive, requiring 110 pounds of nitrogen fertilizer per acre. Some of the fertilizer is broken down by soil bacteria into nitrate, a toxic and highly soluble chemical that can leach into groundwater or get washed into lakes, creating oxygenless dead zones.
