How much greenhouse gas do tropical soils emit?

Nitrogen changes form as it cycles between air, soil, and life. Soils, for example, emit nitrogen either as inert dinitrogen (N2), which dominates our atmosphere, or as nitric oxide (NO) or nitrous oxide (N2O), the greenhouse ...

Developing an eco-friendly ammonia catalyst

A DGIST research team led by Professor Sangaraju Shanmugam, Department of Energy Engineering, developed a catalyst that converts nitric oxide (NO) to ammonia (NH3). This electrochemical technology offers high Faradaic efficiency ...

Examining the intricacies of the nitrogen cycle

Nitrogen may not get the same level of attention as its neighbors on the periodic table, carbon and oxygen. But like its neighbors, it's an element we can't live without.

Plasma-produced gas helps protect plants against pathogens

The flash of lightning and the dance of auroras contain a fourth state of matter known as plasma, which researchers have harnessed to produce a gas that may activate plant immunity against wide-spread diseases.

Soil temperature drives nitric oxide emission

Nitric oxide (NO) is a major contributor to atmospheric pollution, and forest soil is an important source of NO emission. However, there are great uncertainties in global forest soil NO emission due to lack of high-frequency ...

Discovery uncovers need for ammonia emission regulations

A discovery by former Carnegie Mellon Ph.D. student, Mingyi Wang, leading a large collaborative team, sheds light on one way new particles are forming in the upper troposphere. The study, published in Nature, reveals an unexpected ...
