Outside the laboratory, other oxidizing pollutants such as nitrogen oxides, which cannot be tested in laboratory experiments because of their toxicity, can amplify the effect of ozone.

Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry.

As described in a paper just published in the journal Advanced Materials, a thin layer of magnesium keeps tantalum from oxidizing, improves its purity, and raises the temperature at which it operates as a superconductor.

The aforementioned plasma components, when interacting with water, generate oxidizing species capable of degrading organic compounds and killing microorganisms, which allows this plasma reactor to be used in applications related to water remediation.

"However, the method only detects water that was used up in oxidizing iron," adds Asimow.
