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.
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.
Wet getting wetter and dry getting dryer, or global aridification? This Review examines the applicability and limits of both hypotheses across different frameworks, scales and contexts, providing insights on hydrologic change and the future of water availability.
Recent toxicological studies have indicated that the poorly characterized high-molecular-weight fraction of disinfection by-products may contribute more to toxicity than the carbon disinfection by-products of current research interest. This Review summarizes what is known about the high-molecular-weight fraction and suggests pathways for future research in this area.
The story of satellite gravimetry’s progression from the fringes of hydrology to being a staple of large-scale water cycle and water resources science and the sole source of global observations of terrestrial water storage now an ‘essential climate variable’.
