High purity nitrogen gas can be obtained using an "in-house" system with a hollow fiber membrane which separates the nitrogen from oxygen and water vapor in compressed air. A small compressor is used which requires...

Even nitrogen, which is a gas in its elemental state, is normally absorbed from the soil as nitrate ions. Some soils are notoriously deficient in micro nutrients and are therefore unable to support most plant life. So-called serpentine soils, for example, are deficient in calcium, and only ...

What is the function of greenhouse gases and how do they work? Describe how methane gas can be generated, and explain why it is considered to be a greenhouse gas. What are greenhouse gases? What do they do? Are they good or are they bad?
.According to a report by the European Environment Agency,aviation is responsible for around 3% of the EU's greenhouse gas emissions,and that number is expected to grow in the coming years.In addition,aircraft contribute to other types of air pollution,such as particulate m...
One of the most common GHGs, CO2, is found in the Earth’s atmosphere and, along with nitrogen, oxygen,methane, and other gases, is part of the planet’s air.CO2helps trap heaton Earth, like a greenhouse traps heat to grow tomatoes in cold climates. But too much of it can cause pro...
their bones.If bubbles of nitrogen form inside the bone they can cut off its blood supply.This kills the cells in the bone,and consequently weakens it,sometimes to the point of collapse.Fossil (化石)bones that have caved in on them selves are thus a sign that the animal once had the ...
the production of tropospheric ozone [a greenhouse gas] through the emission of nitrogen oxides…and then there’s a fourth thing, which is that high-flying jets that actually enter the stratosphere can produce some…ozone, and at some altitudes, they may release particulate matter, which would...
