Soil heterotrophic respiration (HR) is an important source of soil-to-atmosphere CO2 flux, but
its response to changes in soil water content (θ) is poorly understood. Earth system models …

Around 50% of humankind relies on groundwater as a source of drinking water. Here we
investigate the age, geochemistry, and microbiology of 138 groundwater samples from 95 …

N2O is a highly potent greenhouse gas and arable soils represent its major anthropogenic
source. Field-scale assessments and predictions of soil N2O emission remain uncertain and …

Despite its environmental significance, little is known about denitrification in vadose zones
owing to the complexity of such environments. Here, we investigated denitrification in …

Dissolved gases have a substantial influence on acoustic cavitation and sonochemical
oxidation reactions. Little research on the changes in dissolved gases and the resultant …

The timing and magnitude of greenhouse gas (GHG) production depend strongly on soil
oxygen (O 2) availability, and the soil pore geometry characteristics largely regulate O 2 and …

Groundwater artificial recharge has been widely utilised throughout the world as an effective
measure for solving groundwater overdraft. Many microorganisms are present in both …

In geologic, biologic, and engineering porous media, bubbles (or droplets, ganglia) emerge
in the aftermath of flow, phase change, or chemical reactions, where capillary equilibrium of …

Increased water demands have led to a notable interest in the use of treated wastewater for
reuse. Typically, this results from the implementation of advanced treatment of final effluent …

The low hydraulic loading rate (HLR) greatly restricts the wide application of subsurface
wastewater infiltration system (SWIS) in densely populated areas. To increase the HLR, an …
