Application of Neural Networks for Advanced Ir Spectroscopy Characterization of Ceria Catalysts Surfaces

Advanced Intelligent Discovery, EarlyView.
A novel convolutional neural network architecture enables rapid, unsupervised analysis of IR spectroscopic data from DRIFTS and IRRAS. By combining synthetic data generation with parallel convolutional layers and advanced regularization, the model accurately resolves spectral features of adsorbed CO, offering real‐time insights into ceria surface ...

Method and timing of grassland renovation affects herbage yield, nitrate leaching, and nitrous oxide emission in intensively managed grasslands [PDF]

, 2010
Managed grasslands are occasionally ploughed up and reseeded in order to maintain or increase the sward productivity. It has been reported that this renovation of grassland is associated with a flush of soil organic nitrogen (N) mineralization and with a

Emissions of N2O from fertilized and grazed grassland on organic soil in relation to groundwater level [PDF]

Intensively managed grasslands on organic soils are a major source of nitrous oxide (N2O) emissions. The Intergovernmental Panel on Climate Change (IPCC) therefore has set the default emission factor at 8 kg N–N2O ha-1 year-1 for cultivation and ...

A new method for continuous measurements of oceanic and atmospheric N2O, CO and CO2: performance of off-axis integrated cavity output spectroscopy (OA-ICOS) coupled to non-dispersive infrared detection (NDIR) [PDF]

, 2013
A new system for continuous, highly-resolved oceanic and atmospheric measurements of N2O, CO and CO2 is described. The system is based upon off-axis integrated cavity output spectroscopy (OA-ICOS) and a non-dispersive infrared analyzer (NDIR) both ...

Characteristics of multiple‐year nitrous oxide emissions from conventional vegetable fields in southeastern China [PDF]

, 2011
The annual and interannual characteristics of nitrous oxide (N2O) emissions from conventional vegetable fields are poorly understood. We carried out 4 year measurements of N2O fluxes from a conventional vegetable cultivation area in the Yangtze River ...

The effect of renovation of long-term temperate grassland on N2O emissions and N leaching from contrasting soils [PDF]

, 2016
pre-printRenovation of long-term grassland is associated with a peak in soil organic N mineralisation which, coupled with diminished plant N uptake can lead to large gaseous and leaching N losses.

Establishment of a Purge and Trap Continuous-Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ¹⁵N and δ¹⁸O) in Water Samples by Ti(III) Reduction. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.

Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

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 ...

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.
