The growing need for food has led to a rising demand for fertilizers—especially nitrogen. But making nitrogen fertilizers ...

If it can be separated, urine can act to partly sterilize itself. The nitrogen in urine leaves the body as urea, a simple organic compound. Bacteria in pipes typically break down urea into ammonia.

Researchers have discovered an efficient, low-carbon way to generate green hydrogen by using urea that's found in urine and ...

“Prior to our method, the traditional method of separating [the nitrogen-rich compound] urea from urine was to concentrate urine to precipitate urea and inorganic salts, and then purify urea by ...

while microorganisms transform the urea in the urine into nitrate, a form of nitrogen that plants can absorb more easily. The nitrate produced in the reactor is then used to irrigate the ...

The urine volume most closely paralleled the osmolar excretion and particularly its major component, the minute excretion of urea. After the blood urea nitrogen returned to normal the diuresis ceased.

Researchers have developed two unique energy-efficient and cost-effective systems that use urea found in urine and wastewater ... our systems produce harmless nitrogen gas instead of the toxic ...

In fact, some call urine “liquid gold” because it is loaded with elements that plants desire. The waste product is packed with phosphorus, potassium, and nitrogen in the form of urea ...

Your body forms urea (a waste product that's a major component of urine) when elements such as carbon, hydrogen, and oxygen combine with the nitrogen that’s produced by your liver. The urea then ...

and it travels to the kidneys for removal in the urine. Urea contains nitrogen and is also the compound responsible for helping clear excess nitrogen from the body. For this reason, people often ...

In the records of some of these patients there is evidence of the production of copious or dilute urine at the time when the low blood urea nitrogen was noted. The patient who was not given ...
