    Review Article
  • Using three prototypical scenarios of water contamination from legacy pollutants at contaminated sites, agricultural use of pesticides and abatement of pharmaceuticals and disinfection by-products in water treatment systems, this Review illustrates success stories of compound-specific isotope analyses and ongoing developments for future applications.

    Review Article
  • 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.

    Review Article
  • 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.

    Review Article
  • 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.
