The position of gas turbine power plants with respect to the emission of nitrogen oxides by fossil-fueled energy installations [PDF]

open access: yes
The amount of nitrogen oxides introduced into the atmosphere by gas turbines is very significant in relation to the total amount of nitrogen oxide emissions produced by chemical installations and combustion engines.

Coupled anoxic nitrification/manganese reduction in marine sediments [PDF]

open access: yes, 1999
Pore water and solid phase distributions of oxygen, manganese, and nitrogen from hemipelagic and shelf sediments sometimes indicate a close coupling between the manganese and nitrogen redox cycles.

Redução catalítica seletiva de óxidos de nitrogênio sobre hematita contendo cobre The selective catalytic reduction of no over copper-containing hematite

open access: yesQuímica Nova, 2007
The activity of copper-doped hematite in the SCR with propane, in the presence of oxygen, was evaluated in this work. It was found that copper sulfate led to the production of solids with different specific surface areas depending on the amount of copper.

A transformative route to nanoporous manganese oxides of controlled oxidation states with identical textural properties [PDF]

open access: yes, 2014
Nanoporous nanocrystalline metal oxides with tunable oxidation states are crucial for controlling their catalytic, electronic, and optical properties. However, previous approaches to modulate oxidation states in nanoporous metal oxides commonly lead to ...
