It demonstrates the laboratory preparation of nitric acid through the reaction of sodium nitrate and sulfuric acid, ... highlighting reactions that produce hydrogen gas and various nitrogen oxides.

Painting a clear picture of how nitrogen oxides are formed Date: March 12, 2018 Source: DOE/Argonne National Laboratory Summary: For decades, combustion researchers and engine companies have been ...

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.

This rate-limiting step might be accelerated by fine-tuning the spatial distribution of the copper ions, leading to lower nitrogen oxide emissions at cooler temperatures than now possible. To make ...

COMBUSTION to carbon dioxide is part of the preparation of most samples for radiocarbon dating. The procedures so far adopted by dating laboratories for this process have followed the example set ...

IN an investigation on the feasibility of using gas-chromatographic methods to determine the oxides of nitrogen in gaseous mixtures such as Diesel exhaust gases, we have successfully used a ...

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.

Picarro Inc., a global leader in gas concentration and stable isotope analyzers, today introduced the PI5131-i Analyzer, a cutting-edge mid-infrared (mid-IR) analyzer designed for fast, high ...

Of these markets, they found vehicles emitted 13.2 million tons of nitrogen oxide under real-world driving conditions, which is 4.6 million tons more than the 8.6 million tons expected from ...
