Kontrolle heterogener Katalyse mittels Unter‐Oberflächen‐Sauerstoff

Angewandte Chemie, EarlyView.
Während der CO‐Oxidation auf Rhodiumoberflächen wird die Reaktionsdynamik in der Gegenwart von Unter‐Oberflächen‐Sauerstoff (Osub) deutlich verändert. Unter‐Oberflächen‐Sauerstoff stabilisiert vorübergehend durch Oberflächenreaktionen gebildetes physisorbiertes CO2, was diesem ermöglicht, vorübergehend zu binden und mit der Oberfläche zu thermalisieren.

Bayesian calibration of the nitrous oxide emission module of an agro-ecosystem model [PDF]

, 2008
Nitrous oxide (N2O) is the main biogenic greenhouse gas contributing to the global warming potential (GWP) of agro-ecosystems. Evaluating the impact of agriculture on climate therefore requires a capacity to predict N2O emissions in relation to ...

Controlling Heterogeneous Catalysis With Subsurface Oxygen

Angewandte Chemie International Edition, EarlyView.
During CO oxidation on rhodium surfaces, the reaction dynamics are markedly altered in the presence of subsurface oxygen. Subsurface oxygen stabilizes the nascent physisorbed CO2 formed after the surface reaction, allowing it to become transiently trapped and thermalize with the surface.

Strategic Sustainability Assessment in the Construction Sector: A Multidimensional Index for Decision Making in Decentralised Economies

Business Strategy and the Environment, EarlyView.
ABSTRACT This article evaluates the average business performance of construction firms across Spain's 17 autonomous communities within a decentralised governance framework. A regional composite sustainability index is developed, integrating economic, social and environmental intensity indicators.

N2O emission from grass-clover swards is largely unaffected by recently fixed N2 [PDF]

, 2004
The contribution of biologically fixed dinitrogen (N2) to the nitrous oxide (N2O) production in grasslands is unknown. To assess the contribution of recently fixed N2 as a source of N2O and the transfer of fixed N from clover to companion grass, mixtures

Multi-point monitoring of nitrous oxide emissions and aeration efficiency in a full-scale conventional activated sludge tank [PDF]

, 2017
In this work the biological tank of a WRRF in Italy was monitored placing five floating hoods on a plug-flow-like biological aerated tank surface in order to capture emission dynamics in both time and space domains.

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.

Detailed regional predictions of N2O and NO emissions from a tropical highland rainforest [Discussion paper] [PDF]

, 2013
Tropical forest soils are a significant source for the greenhouse gas N2O as well as for NO, a precursor of tropospheric ozone. However, current estimates are uncertain due to the limited number of field measurements.

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 ...

Concentration and Detection Time of Nitrous Oxide in Blood Following Controlled Inhalation. [PDF]

Drug Test Anal
In a study with controlled inhalation of nitrous oxide (N2O), elimination followed a two‐compartment model with half‐lives of 2.4 and 31 min, and N2O remained detectable in blood samples for 1–3 h after inhalation. ABSTRACT Recreational use of nitrous oxide (laughing gas, N2O) is becoming increasingly common and abuse is often seen in relation to ...
