Fe-based electrodes emerge as an effective and economical option to treat nitrate-laden wastewater. Whereas Fe cathode corrosion is commonly considered as an adverse factor for the electroreduction of nitrate to ammonia, intentional corrosion-induced surficial reconstruction has the potential to enhance catalytic performance.

By utilizing flooding records and county-level daily deaths during 2015 to 2019 across 98 counties in North Carolina, United States, this study found significant associations between cause-specific mortality and short-term exposure to flooding.

Desalination is one of the most important responses to global water challenges. Decision-making on where, how and why to develop desalination plants must focus more on addressing social issues, such as universal access, justice and sustainability.

The El Niño/Southern Oscillation (ENSO) is a critical control on winter precipitation in the Intermountain West of North America but is impacted by mountainous terrain and climate change. This study isolates ENSO impacts from these complicating factors using a spatially distributed, nonlinear spline model applied to long-term gauge observations.

Large-scale afforestation is championed as a way to restore degraded habitats, conserve biodiversity and advance societal improvements. In the Middle East, a severely water-stressed region, we argue that urban greening will need to play a major part in efforts to deliver a more sustainable and water-sensitive strategy, while also enhancing urban liveability.

Membranes are useful for removing pollutants from water, but the pore size of most commercial membranes is larger than the molecular size of many trace organic contaminants. Here an engineered covalent organic framework allows pore size regulation to efficiently remove organic pollutants.

Global water models are important tools for understanding the water cycle. This study evaluates eight global water models by focusing on functional relationships that capture the spatial co-variability of forcing and response variables.

Almost 250 years have passed since the invention of the modern flush toilet. With nearly half of the world’s population still lacking access to safely managed sanitation, it is time to accelerate change.

The toilet could evolve from an unassuming household plumbing fixture to a critical engineering node for onsite wastewater treatment and reuse.
