Reaction: Avoid fairy dust when engineering water-purification technologiesPaul WesterhoffChemJune 08, 2023In BriefThis Catalysis article discusses the risks of using nanomaterials for water purification and alternative strategies, painting a fuller picture of research in clean water. Full-Text PDF Catalyst: The roles of chemistry in clean water for allYoung-Shin JunChemJune 08, 2023In BriefUnderstanding nanoscale interfacial reactions unlocks the chemistry controls that are critical for generating clean water. This catalysis article discusses three important roles of chemistry in clean water: understanding and controlling evolving interfaces induced by nucleation, deciphering and utilizing hidden interfaces in nanoconfined spaces, and harnessing interfaces with functionalized surfaces. Chemically guided developments of new materials and technologies for purifying clean water can bring all water resources back to one H2O, which supports life for all people. Full-Text PDF
