Influence of Cu2O Precursor Surface Orientation on Catalytic Performance and Product Selectivity in Nitrate Reduction Reactions

Chemistry – An Asian Journal, EarlyView.
For nitrate reduction to ammonia, oxide‐derived Cu electrodes were synthesized from Cu₂O with (100)‐ and (111)‐oriented surfaces. The precursor surface orientation influenced onset potential and product selectivity. Notably, the (100)‐derived electrode achieved higher Faradaic efficiency for ammonia, while the (111)‐derived electrode operated at a ...

Sapwood and heartwood are not isolated compartments: Consequences for isotope ecohydrology

Ecohydrology, Volume 15, Issue 8, December 2022., 2022
Abstract In most tree species, xylem consists of two different functional parts: sapwood and heartwood. While sapwood, as the flowpath for sap, has received more attention in isotope studies assessing water sources accessed by trees (e.g. soil water from different depths, groundwater, stream water or a mixture of these), much remains unknown about ...

Non-renewable groundwater use and groundwater depletion: a review

Environmental Research Letters, 2019
Abstract Population growth, economic development, and dietary changes have drastically increased the demand for food and water. The resulting expansion of irrigated agriculture into semi-arid areas with limited precipitation and surface water has greatly increased the dependence of irrigated crops on groundwater withdrawal.

Quantization‐Based Latin Hypercube Sampling for Dependent Inputs With an Application to Sensitivity Analysis of Environmental Models

Applied Stochastic Models in Business and Industry, EarlyView.
ABSTRACT Numerical models are essential for comprehending intricate physical phenomena in different domains. To handle their complexity, sensitivity analysis, particularly screening is crucial for identifying influential input parameters. Kernel‐based methods, such as the Hilbert‐Schmidt Independence Criterion (HSIC), are valuable for analyzing ...

Functional traits of riparian trees in the lower Fitzroy River, Western Australia

Ecohydrology, Volume 16, Issue 1, January 2023., 2023
Abstract Riparian trees are critically important for maintaining the ecological function of freshwater ecosystems. Globally, anthropogenic changes to water regimes are impacting the health and distribution of riparian trees. Understanding the physiological constraints on the distribution of riparian tree species in relation to the water regime is ...

Digestate from small‐scale biogas plants in central Vietnam produced under mesophilic conditions: friend or foe for local farmers?

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study evaluates the suitability of digestate from small mesophilic biogas plants in central Vietnam for agricultural application. Digestate samples were collected from 85 farms and analyzed for microbial contamination and elemental composition.

Regional‐scale partitioning of transmission losses and groundwater recharge using satellite estimates of actual evapotranspiration in an arid environment

Ecohydrology, Volume 16, Issue 1, January 2023., 2023
Abstract Rivers in arid regions often rely on flow generated from wetter regions upstream, leading to high transmission losses of downstream flows. These transmission losses support a range of ecosystems, but partitioning the volume of the transmission losses across the floodplain, riparian zone and in‐channel is difficult.
