This Review identifies factors that lead to ‘unsafely managed sanitation’ in the United States, the specific types of access, and obstacles to characterizing and addressing the problem.
A hybrid photocatalyst–photothermal sheet can effectively harness sunlight to produce hydrogen fuel. At the same time, it can purify open-water sources such as seawater and industrial wastewater.
Crop switching optimization within the context of the Indo-Gangetic Plain provides compelling evidence that this approach yields significant benefits in terms of increasing calorie production and profits for farmers whilst minimizing water and energy use.
The adoption of open-hardware technology is changing current river research monitoring practices, reducing the need for scientists to allocate large portions of their budgets to expensive instrumentation.
Excavation and a geoarchaeological survey provide evidence of an early multi-levelled water management system in the Late-Holocene East Asian Monsoon region.
This Review presents an overview and analysis of biomimetic engineering principles and strategies for developing unique surface properties to design all-weather, portable water harvesting systems. It discusses key processes involved in water harvesting and proposes a framework for designing next-generation sustainable systems to alleviate freshwater scarcity.
Advanced oxidation or reduction processes (AOPs or ARPs) are effective techniques to remove contaminants and pathogens from water. This Review compares them with a new alternative process involving UV activation of low-molecular-weight diketones and explores the shift in water treatment technologies from discrete AOPs and ARPs to combined oxidation–reduction processes.
In this Review, Li and Wang utilize a unique chemical potential-based approach and critically analyse the available literature on sorption-based atmospheric water harvesting, including sorbents, processes and applications beyond water production.
The traditional solution–diffusion model, long used for studying water transport in reverse osmosis membranes, is re-evaluated with molecular dynamics simulations.
Efficiency is only one of the parameters involved in solar evaporation that should be improved to make it practical. Depending on the application, various factors of merit should be taken into consideration, as discussed in this Perspective.
Treatment of brackish groundwater can help to alleviate potential competition for freshwater resources between the power sector and other sectors in water-stressed regions.
The approach based on analysing wastewater to monitor drugs or pathogens in the population had been used for decades before it became widespread during the COVID 19 pandemic. We have asked experts located in a number of different nations to share their views on the potential and limitations of wastewater-based epidemiology in the future.
In this Perspective, the authors survey potential water-system-wide benefits of AI applications from catchments to end-users and then highlight potential systemic barriers, direct risks and exposures to cascading failures, which may prove catastrophic for communities. In response, they make three recommendations for safe and responsible deployment of AI across potable water supply and sewage disposal systems.
