Water treatment is imperative for the recycling, reclamation, and reuse of wastewater, therefore, the global water challenge should be taken and addressed at the national level, as far as governments are concerned. In particular, the treatment of water contaminants is necessary to deliver fit-for-purpose water. Although activated carbon and various polymeric materials have been widely used as efficient adsorbents and filtration membranes, respectively, many water treatment challenges remain, such as scaling and fouling, selective separation, energy-efficient desalination, and the effective removal of micropollutants at extremely low concentrations (e.g., parts per trillion), among many others. Therefore, many opportunities exist for exploring and understanding emerging nanomaterials and nanotechnologies for water treatment and water interfaces.
Volume 2 is a collection of state-of-the-art nanotechnology-based water treatment research. Key water remediation technologies covered include adsorption, membrane filtration (e.g., microfiltration, ultrafiltration, nanofiltration, and reverse osmosis), capacitive deionization, and catalytic degradation, along with methods to minimize scaling and fouling. Materials and interfaces discussed include carbon nanotubes, graphene, graphene oxide, reduced graphene oxide, graphene oxide quantum dots, carbon nitrides, metal-organic frameworks, polymers, metals, metal oxides, composite sponges, and hydrogels. The contaminants addressed include heavy metals, radioactive metals, pathogens, organic pollutants (e.g., dyes, antibiotics, aromatic compounds, and natural organic matter), and other micropollutants in water. We hope this book volume will become a valuable reference not only for veteran researchers in the field of water treatment but also for undergraduate students and graduate students who are entering this exciting field.

Matthew Tirrell is the Dean of the Pritzker School of Molecular Engineering and the Robert A Millikan Distinguished Service Professor at the University of Chicago. Before becoming dean in 2011, Dr Tirrell served as the Arnold and Barbara Silverman Professor and Chair of the Department of Bioengineering at the University of California, Berkeley, and as Professor of Materials Science and Engineering and Chemical Engineering and faculty scientist at Lawrence Berkeley National Laboratory. Prior to that, he was Dean of Engineering at the University of California, Santa Barbara for 10 years.
Dr Tirrell began his academic career at the University of Minnesota as an Assistant Professor in the Department of Chemical and Materials Engineering and later became head of the department. He also served as Deputy Laboratory Director for Science at Argonne National Laboratory, where he was responsible for integrating the laboratory's research and development efforts and science and technology capabilities.
Dr Tirrell is a pioneering researcher in the fields of biomolecular engineering and nanotechnology, specializing in the manipulation and measurement of the surface properties of polymers, which are materials that consist of long, flexible chain molecules. His work combines microscopic measurements of intermolecular forces with the creation of new structures. His work has provided new insight into the properties of polymers, especially surface phenomena such as adhesion, friction, and biocompatibility, and new materials based on the self-assembly of synthetic and bioinspired materials. Dr Tirrell has received many honors, including the Polymer Physics Prize by the American Physical Society and election to the National Academy of Sciences, National Academy of Engineering, and the American Academy of Arts and Sciences.
