Electro-catalytic Reduction of Nitrogen Oxides [PDF]

open access: yes, 1989
Nitrogen oxides have been linked to a broad range of air pollution problems including acid rain and the atmospheric production of photochemical ozone. Over twenty million tons of nitrogen oxides are emitted into the atmosphere each year as a result of ...

Shipping nitrogen oxides recycling via isoprene nitrate amplifies forest ozone

open access: yesCommunications Earth & Environment
Forests are essential for climate stability, yet elevated ozone levels-exacerbated by poorly understood impacts of shipping-related nitrogen oxides, stress these ecosystems.

Influence of Pollutants from Transport on Life Expectancy in the EU Countries

open access: yesProblemy Ekorozwoju, 2021
Road transport has become the major source of environmental pollution and it is also one of the biggest environmental risks in the EU countries. Good air quality is very important for population as pollutants have negative impacts on human health.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Nitrogen Oxides from Thunderstorms - Results from Experiments over Europe and the Continental Tropics [PDF]

open access: yes, 2004
Deep convection causes thunderstorms with lightning. In this paper we summarise the nitrogen oxides results obtained from the recent measurements over Brazil within the experiment TROCCINOX and compare the results with the results from EULINOX and its ...

An improved retrieval of tropospheric nitrogen dioxide from GOME [PDF]

open access: yes, 2002
We present a retrieval of tropospheric nitrogen dioxide (NO2) columns from the Global Ozone Monitoring Experiment (GOME) satellite instrument that improves in several ways over previous retrievals, especially in the accounting of Rayleigh and cloud ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Bimetallic Monolithic Catalyst For Selective Catalytic Reduction Of Nox In Diesel Engine Exhaust [TD885.5.N5 H216 2008 f rb]. [PDF]

open access: yes, 2008
Nitrogen oksida (NOx) merupakan pencemar udara utama di seluruh dunia. Penurunan bermangkin NOx tertentu dengan hidrokarbon adalah kaedah yang berpotensi dalam menyingkirkan NOx dari ekzos diesel.

Comparison of NOx and Smoke Characteristics of Water-in-Oil Emulsion and Marine Diesel Oil in 400-kW Marine Generator Engine

open access: yesEnergies, 2019
Currently, the exhaust gas of a ship is regulated for nitrogen oxides and sulphur compounds; however, there is no IMO regulation on smoke under discussion.
