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.
All we are is a lot of talking nitrogen.
Agricultural husbandry essentially maintains the balance of bound nitrogen.
She is oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Under natural conditions, the soil does not lose its fixed nitrogen.
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.
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.
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?
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.
The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.
The four most common chemically active elements in the universe—hydrogen, oxygen, carbon, and nitrogen—are the four most common elements of life on Earth. We are not simply in the universe. The universe is in us.
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 Swedish Academy of Sciences has seen fit, by awarding the Nobel Prize, to honour the method of producing ammonia from nitrogen and hydrogen.
This is what works for me: I practise crop rotation with my creative endeavours. I’ve found that when the nitrogen runs out in the soil in one field, it’s best to leave it fallow for a while and cultivate another.
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.
The God of the universe--the creator of nitrogen and pine needles, galaxies and E-minor--loves us with a radical, unconditional, self-sacrificing love. And what is our typical response? We go to church, sing songs, and try not to cuss.
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.
Plants have to eat, too,” I tried to explain. “They need nitrogen, they need minerals. You have to replace what you’re taking out. Your choices are fossil fuels or animal products.
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 mer...
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.
