The effect of nanosilica sizes in the presence of nonionic TX100 surfactant on CO2 foam flooding
Petroleum Research, 2022 The aim of this research is to study the effect of hydrophilic silica nanoparticles, sizes as CO2 foam stabilizer in the presence of nonionic TX100 surfactant. Two nanosilica sizes, 15 and 70 nm, have been examined thoroughly.

Interpretation of stem CO2 efflux measurements [PDF]
Tree Physiology, 2009 It is known that stem CO2 efflux differs somewhat both temporally and spatially from actual stem respiration, but relations between these two are not fully understood. A physical model of CO2 diffusion and advection by xylem sap flow is developed to interpret the CO2 flux signal from the stem.

Effect of near-surface winds on the measurement of forest soil CO2 fluxes using closed air chambers
Frontiers in Ecology and Evolution, 2023 Forest soil CO2 flux measurements are important for studying global climate change. Current monitoring methods are based on closed gas chambers, which block the wind pumping effect of near-surface winds in the measurements, resulting in biased values ...

The influence of nocturnal CO2 advection on CO2 flux measurements [PDF]
Basic and Applied Ecology, 2000 Abstract Eddy covariance (EC) measurements of CO2 are widely used to assess the CO2 budget of ecosystems. However, important uncertainties exist about how to obtain flux values that are representative for the regional scale from local-scale EC measurements.
