Modelling effects of acid deposition and climate change on soil and run-off chemistry at Risdalsheia, Norway [PDF]

open access: yesHydrology and Earth System Sciences, 2001
Elevated carbon dioxide levels, caused by anthropogenic emissions of carbon dioxide to the atmosphere, and higher temperature may lead to increased plant growth and uptake of nitrogen, but increased temperature may lead to increased nitrogen ...

Oxidation of cellulose in pressurized carbon dioxide [PDF]

open access: yes, 2009
This work presents first results upon oxidation of type II cellulose by nitrogen dioxide dissolved in carbon dioxide at high pressure. This reaction leads to oxidized cellulose, a natural-based bioresorbable fabric used for biomedical applications.

Nitrogen dioxide plumes reveal areas of industrialization: part 1

open access: yes, 2016
Nitrogen dioxide is a toxic compound, often associated with an orange-brown color, and is a major air pollutant, especially in industrial areas. This image is a composite of one month of data during September 2010. It shows very large concentrations over

The Antarctic stratospheric nitrogen hole: Southern Hemisphere and Antarctic springtime total nitrogen dioxide and total ozone variability as observed by Sentinel-5p TROPOMI [PDF]

open access: yesAtmospheric Chemistry and Physics
Denitrification within the stratospheric vortex is a crucial process for Antarctic ozone hole formation, resulting in an analogous stratospheric “nitrogen hole”.

Effect of the CO2 top-blowing ratio on the end of the converter

open access: yes工程科学学报, 2022
When combined with the high-temperature reaction characteristics of carbon dioxide—that is, the weak oxidation, endothermic, or weak exothermic effect compared with oxygen and the bubble increment effect of reacting with carbon to produce twice the gas ...

Kinetics of Nitrogen Dioxide Fluorescence [PDF]

open access: yesThe Journal of Chemical Physics, 1969
The fluorescence lifetime and intensity of gas-phase nitrogen dioxide (2B1) have been measured as a function of excitation wavelength, fluorescence wavelength, and pressure (0.5–50 mtorr). The phase-shift method was used; this technique allows lifetime measurements to be obtained with signal intensities of 100 counts per sec and lower.
