Land inclination controls CO2 and N2O fluxes, but not CH4 uptake, in a temperate upland forest soil Universiteit Gent
Inclination and spatial variability in soil and litter properties influence soil greenhouse gas (GHG) fluxes and thus ongoing climate change, but their relationship in forest ecosystems is poorly understood. To elucidate this, we explored the effect of inclination, distance from a stream, soil moisture, soil temperature, and other soil and litter properties on soil–atmosphere fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) ...
Development of NO2 and NOx land use regression models for estimating air pollution exposure in 36 study areas in Europe - The ESCAPE project Universiteit Hasselt
Estimating within-city variability in air pollution concentrations is important. Land use regression (LUR) models are able to explain such small-scale within-city variations. Transparency in LUR model development methods is important to facilitate comparison of methods between different studies. We therefore developed LUR models in a standardized way in 36 study areas in Europe for the ESCAPE (European Study of Cohorts for Air Pollution Effects) ...
Top-down NOX emissions of European cities based on the downwind plume of modelled and space-borne tropospheric NO2 columns Universiteit Gent
Biologically mediated release of endogenous Nâ‚‚O and NOâ‚‚ gases in a hydrothermal, hypoxic subterranean environment Universiteit Antwerpen
The migration of geogenic gases in continental areas with geothermal activity and active faults is an important process releasing greenhouse gases (GHG) to the lower troposphere. In this respect, caves in hypogenic environments are natural laboratories to study the compositional evolution of deep-endogenous fluids through the Critical Zone. Vapour Cave (Alhama, Murcia, Spain) is a hypogenic cave formed by the upwelling of hydrothermal CO2-rich ...
Adsorption of CO2 and N-2 in Na-ZSM-5: effects of Na+ and Al content studied by Grand Canonical Monte Carlo simulations and experiments Vrije Universiteit Brussel
Zeolite crystals with cations present, such as ZSM-5, are widely used for gas sequestration, separations, and catalysis. One possible application is as an adsorbent to separate CO2 from N-2 in flue gas mixtures. Typically, the zeolite framework is of a SiO2 composition, but tetravalent Si atoms can be replaced with trivalent Al atoms. This change in valence creates a charge deficit, requiring cations to maintain the charge balance. Experimental ...
