Elemental Mercury Removal over CeO2/TiO2 Catalyst Prepared by Sol–Gel Method

open access: yesApplied Sciences, 2020
Elemental mercury (Hg0) emitted from a coal-fired boiler is a serious menace and challenge to humans. Using high-efficiency CeO2/TiO2 catalysts to enhance the conversion from elemental mercury to oxidized mercury is a promising approach to reducing Hg0 ...

Bounds and Bunching: Distributions of Air Pollutants Produced by New Automobiles

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015
Euro norms set limits on per-kilometer emissions of air pollutants produced by new cars. Satisfying these limits is always costly, the existing models generally assume that cars are produced as to just satisfy the norms.

The nitrogen oxide synthase effect in endothelium reaction and change in peripheral perfusion under THz radiation of nitrogen oxide occurrence exposure

open access: yesRussian Open Medical Journal, 2013
There is new information about the mechanism of THz radiation of molecular emission and absorption spectrum (MEAS) of 150.176-150.664 GHz nitrogen oxide occurrence exposure. Organized experiments let us establish the fact that a normalizing effect of THz

Structure and Oxidation of Nitrogenous Substances [PDF]

open access: yesNature, 1935
IT has been reported elsewhere1 that organic nitrogen in plant materials, soil organic matter and extracted proteins undergoes partial oxidation to nitrate on treatment with a mixture of sulphuric and chromic acids. It has since been found that the proportion of total nitrogen recovered as ammonia is constant for each substance, provided the oxidation ...
