Denitrification in sediments of headwater streams in the southern Appalachian Mountains, USA
… incubated at ambient stream temperatures, and nitrous oxide accumulation was quantified following acetylene inhibition of nitrous oxide reduction. Denitrification potential was greater in Noland Creek than Walker Branch and was generally greater in sediments from the higher-nitrate streams. In …

Catalytic Reduction of NO and N2O with Hydrogen in Water by Polymer-Protected Palladium Nanoparticles
Nitric oxide (NO) and nitrous oxide (N2O) are important components of the global nitrogen cycle. They are intermediates or end products for natural bacterial processes such as nitrification and denitrification, and are formed in increasing amounts from anthropogenic sources such as increased …

Continuous synthesis of metallic and oxidic palladium nanoparticles with tunable sizes for catalytic applications
… palladium, as the active catalyst materials and oxides such as cerium dioxide as support. Palladium and palladium-based cerium dioxide catalysts have been extensively studied in three-way catalysis due to their excellent catalytic properties. However, ambiguity in mechanistic knowledge persists, …

Performance, denitrification activity, and microbial community dynamics of denitrifying biofilters under fluctuating water level
… nosZ, the gene encoding the catalytic subunit of nitrous oxide reduction. In the laboratory biofilter study, the performance was sensitive to changing water level, with 31% nitrate removed at high water level and 59% at low water level. The denitrification potential was the same under almost all …

On-Board-Reduktionsmittelherstellung zur NO x-Emissionsminderung bei Dieselfahrzeugen
The reduction of Diesel engine exhaust NOx emissions requires a reductant due to the composition (high oxygen content) of the exhaust gas. An efficient reductant is selected based on the comparison of literature data of different NOx reduction processes. A process for the on-board synthesis of this …
