Modelling N2O dynamics of activated sludge biomass under nitrifying and denitrifying conditions: pathway contributions and uncertainty analysis [PDF]

open access: yesarXiv, 2018
Nitrous oxide (N2O) is a potent greenhouse gas emitted during biological wastewater treatment. A pseudo-mechanistic model describing three biological pathways for nitric oxide (NO) and N2O production was calibrated for mixed culture biomass from an activated sludge process using laboratory-scale experiments.

Precision frequency comb spectroscopy of the $^{14}$N$_{2}$O, $^{14}$N$^{15}$NO, $^{15}$N$^{14}$NO, and $^{15}$N$_{2}$O isotopocules in the 3300-3550 cm$^{-1}$ range [PDF]

open access: yesarXiv
Nitrous oxide is a long-lived greenhouse gas. Its isotopic composition provides valuable insights into sources and sinks, and about the mechanism of formation. A major challenge in the spectroscopic analysis of the isotopocule compositions is the availability of accurate spectroscopic parameters, particularly for the minor $^{15}$N isotopocules.

Similarity indexing & GIS analysis of air pollution [PDF]

open access: yesarXiv, 2019
Pollution has become a major threat in almost all metropolitan cities around the world. Currently, atmospheric scientists are working on various models that could help us understand air pollution. In this paper, we have formulated a new metric tool called Delhi Similarity Index (DSI).
