TL;DR: Recent development in nanotechnology for water and wastewater treatment is reviewed, covering candidate nanomaterials, properties and mechanisms that enable the applications, advantages and limitations as compared to existing processes, and barriers and research needs for commercialization.

TL;DR: The modular, multifunctional and high-efficiency processes enabled by nanotechnology provide a promising route both to retrofit aging infrastructure and to develop high performance, low maintenance decentralized treatment systems including point-of-use devices.

TL;DR: In this article, the chemical and structural properties of bulk, colloidal, and dissolved BC were thoroughly examined using elemental analysis and a variety of spectroscopic techniques, and it was concluded that dissolved BC consists primarily of small aromatic clusters substituted by carboxylic groups, and by phenolic groups to a less extent.

TL;DR: Dissolved black carbon released from biochar decreased its ability to further generate ROS due to lower light absorption, which has significant implications on the environmental fate of dissolved BC and that of priority pollutants.

TL;DR: Gold ion (Au3+) was used as a model heavy metal ion to quantitatively assess the role of EPS in biomineralization and discern the responsible functional groups, indicating a previously overlooked, universally significant contribution of EPS to the reduction, mineralization, and potential detoxification of metal species with high oxidation state.
