Diazotrophs: An Overlooked Sink of N2O

Geophysical Research Letters
The ocean is the second‐largest source of greenhouse gas nitrous oxide (N2O). However, its role as an N2O sink is severely overlooked. N2O fixation by diazotrophs has lately been proposed as a new pathway of N2O consumption.

Unprecedented N2O production by nitrate-ammonifying Geobacteraceae with distinctive N2O isotopocule signatures

mBio
Dissimilatory nitrate reduction to ammonium (DNRA), driven by nitrate-ammonifying bacteria, is an increasingly appreciated nitrogen-cycling pathway in terrestrial ecosystems.

Nitrous oxide content and fluxes in Setúbal Bay, Portugal, during upwelling events

Ciencias Marinas, 2011
To evaluate the influence of upwelling events on nitrous oxide (N2O) levels and sea-air exchange in Setúbal Bay (SW Portugal), measurements of dissolved N2O were carried out from the surface down to 200 m depth in May 2006 and May 2007.

Greenhouse Gas Emissions and Cost of Debt: Evidence From European Firms Under Mandatory and Voluntary Disclosure

Business Strategy and the Environment, EarlyView.
ABSTRACT Considering the growing attention to sustainability and the increasing regulatory pressure in the European landscape, this study evaluates whether greenhouse gas emissions affect firms' cost of debt. A panel regression was conducted from 2021 to 2024 on two samples of European firms.

Respiration and growth of Paracoccus denitrificans R-1 with nitrous oxide as an electron acceptor

Microbiology Spectrum
In the nitrogen biogeochemical cycle, the reduction of nitrous oxide (N2O) to N2 by N2O reductase, which is encoded by nosZ gene, is the only biological pathway for N2O consumption.

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...

CO2‐Driven Synthesis of Holey Edge‐Carboxylated Graphene for Tunable Electronic Interactions in Cu–CeO2‐Catalyzed Water‐Gas Shift Reaction

Carbon Energy, EarlyView.
Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.

N2O emission and the N2O/(N2O + N2) product ratio of denitrification as controlled by available carbon substrates and nitrate concentrations

Agriculture, Ecosystems & Environment, 2012
Abstract Amending agricultural soils with organic residues is frequently recommended to improve soil fertility and to sequester carbon for counteracting global warming. However, such amendments will enhance microbial respiration, hence denitrification. Therefore, the assessment of effects on global warming must take N2O emission and the N2O/(N2O + N2)

The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Voltammetric Determination of Dissolved Nitrous Oxide

International Journal of Electrochemical Science, 2011
The platinum disk electrode has been tested as a working electrode for the cathodic reduction of N2O in aqueous solutions using 0.2 M K2SO4 as supporting electrolyte, buffered at pH = 12, and a scan rate of 100 mV s-1.
