Influences of Land Use/Cover Types on Nitrous Oxide Emissions during Freeze-Thaw Periods from Waterlogged Soils in Inner Mongolia.

PLoS ONE, 2015
Nitrous oxide emissions during freeze/thaw periods contribute significantly to annual soil N2O emissions budgets in middle- and high-latitude areas; however, the freeze/thaw-related N2O emissions from waterlogged soils have hardly been studied in the ...

Nitrous oxide in fresh water systems: An estimate for the yield of atmospheric N2O associated with disposal of human waste [PDF]

The N2O content of waters in the Potomac and Merrimack Rivers was measured on a number of occasions over the period April to July 1977. The concentrations of dissolved N2O exceeded those which would apply in equilibrium with air by factors ranging from ...

Improving and disaggregating N2O emission factors for ruminant excreta on temperate pasture soils [PDF]

, 2016
pre-printCattle excreta deposited on grazed grasslands are a major source of the greenhouse gas (GHG) nitrous oxide (N2O). Currently, many countries use the IPCC default emission factor (EF) of 2% to estimate excreta-derived N2O emissions.

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

Chemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

Intermediate soil acidification induces highest nitrous oxide emissions

Nature Communications
Global potent greenhouse gas nitrous oxide (N2O) emissions from soil are accelerating, with increases in the proportion of reactive nitrogen emitted as N2O, i.e., N2O emission factor (EF). Yet, the primary controls and underlying mechanisms of EFs remain

Improving Scope 3 Procurement Emissions Accounting: Key Challenges and a Strategic Approach Using MICMAC and the Sustainability Balanced Scorecard

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the reliability of Scope 3 emissions accounting, focusing on purchased goods and services, a critical area for corporate decarbonization. Key barriers include data quality issues, inconsistent methodologies, and limited organizational alignment.

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.

Exploring the Interrelationships Among Supply Chain Emissions, Financial Performance, Market Value, and Board Sustainability: An Exploration of the European Landscape

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT National and supranational institutions are establishing emission trading systems and control schemes in an attempt to manage stakeholders' willingness to engage with regulatory systems and reduce greenhouse gas emissions (GHG). Nonetheless, despite the national and supranational focus on carbon neutrality, little research has been centered ...

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.
