It demonstrates the laboratory preparation of nitric acid through ... highlighting reactions that produce hydrogen gas and various nitrogen oxides. It also examines the oxidizing strength of ...

Now researchers have synthesized more than a decade's worth of combustion studies to create a new overarching model of how nitrogen oxides are ... Energy's Argonne National Laboratory and the ...

In a laboratory experiment, engineering students found that ordinary clay roof tiles sprayed with titanium dioxide removed 88% to 97% of nitrogen oxide pollution from the air. Nitrogen oxides ...

Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution-control systems to further reduce emissions of smog-causing nitrogen oxides in diesel ...

That might explain why earlier studies missed the nitrogen oxides that plants release, Hari says. Scientists often measure tree emissions under lab conditions that lack normal UV exposure or in ...

Diesel cars, trucks, and other vehicles in more than 10 countries around the world produce 50 percent more nitrogen oxide emissions than lab tests show, according to a new study. The extra ...

Of these markets, they found vehicles emitted 13.2 million tons of nitrogen ... laboratory tests. Chris Malley, from the SEI, University of York, said: "This study shows that excess diesel ...

according to the Los Alamos National Laboratory. Other scientists, including Carl Wilhelm Scheele and Joseph Priestly, were working on the same problem, and called nitrogen "burnt" air ...

This material reduces the concentration of nitrogen oxides (NOx) by 25 to 45 per cent ... new paving stones had already been shown in the laboratory, but these results now show that they also ...

“With this significant advance we can finally understand how the nitrogen in the air we breathe is created: from rocket fuel and nitric oxide!” concludes Marc ... Department of Laboratory Medicine, ...
