Effects of nitrogen, sulphur, and temperature treatments on the spectral, structural, and electrochemical characteristics of graphene oxide for energy storage applications

open access: yesCarbon Trends, 2023
The structural and surface modifications have been studied on the hydrothermally Nitrogen (N) and Sulphur (S) doped and thermally reduced at 350 °C nitrogen-doped, nitrogen-sulfur-doped graphene oxides.

Nitrogen Oxides on Mars.

open access: yesThe Astronomical Journal, 1964
Abstract In a series of recent papers, Kiess and collaborators have announced the identification of nitrogen peroxide on Mars and have attempted to interpret a wide range of Martian phenomena in terms of nitrogen oxides. Analyses of observations at a variety of wavelengths in the present paper, and previously by Sinton, Spinrad and Moroz, place a ...

Association between air pollution and primary liver cancer in European and east Asian populations: a Mendelian randomization study

open access: yesFrontiers in Public Health, 2023
PurposeThe incidence of primary liver cancer is increasing year by year, with environmental factors playing a non-negligible role. At present, many studies are still disputing whether air pollution is associated with primary liver cancer incidence, and ...

A Reactivity Based Emission Inventory for the South Pars and Its Implication for Ozone Pollution Control [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2020
The South Pars zone in Iran encompasses the largest gas refineries and petrochemical complexes in the world. In the South Pars zone, elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from industrial facilities lead to ...

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]

open access: yes, 2005
Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to

Nitrogen diffusion in zinc oxide [PDF]

open access: yesJournal of Applied Physics, 2021
Nitrogen migration in ZnO was investigated by nitrogen isotope diffusion. The samples were deposited using plasma-assisted pulsed laser deposition. Nitrogen concentration depth profiles were obtained from secondary-ion-mass spectrometry measurements, and in gas effusion measurements, the molecular nitrogen flux was measured as a function of the heating
