The oxidation state nitrogen content material which the harmless conversionPROBLEM TO BE SOLVED: To inexpensively treat a substance (factory waste fluid) containing oxidized form nitrogen such as a nitrate, a nitrite or the like to make it harmless.山口 潔實...
External cycling regenerating nitrogen oxides (NOx ≡ NO + NO2) from their oxidative reservoir, NOz, is proposed to reshape the temporal–spatial distribution of NOxand consequently hydroxyl radical (OH), the most important oxidant in the atmosphere. Here we verify the in situ external ...
Ocean circulation supplies the surface ocean with the nutrients that fuel global ocean productivity. However, the mechanisms and rates of water and nutrient transport from the deep ocean to the upper ocean are poorly known. Here, we use the nitrogen isot
A constant flow of approximately 340 ml/min of 99.9% pure nitrogen (for the dynamic pyrolysis) or air (for the incineration) was pumped through the tube, with a flow meter used to regulate the gas flow at the system inlet. The exhaust gas was bubbled through three plastic cylinders ...

In this work, the application of advanced oxidation processes (AOPs) for the removal of antibiotics from water has been reviewed. The present concern about water has been exposed, and the main problems derived from the presence of emerging pollutants hav

The only main difference to the regulation in facultative anaerobic photosynthetic purple bacteria appears to be the absence of an energy-intensive redox-balancing system based on the fixation of carbon dioxide or nitrogen (so far no genes encoding enzymes of both pathways were detected in obligately...

The specific area (SBET), pore volume (PV), and pore size for both samples were measured using the Brunauer–Emmett–Teller (BET) method, depending on the isotherms of nitrogen adsorption/desorption. In contrast, the Barrett–Joyner–Halenda (BJH) method was used to determine the pore volume...
