• Sommario/riassunto: At the nano size materials often take on unique and sometimes unexpected properties which results in materials being 'tuned' to build faster, lighter, stronger and more efficient devices and systems, as well as new classes of materials. In the water research, nanotechnology is applied to develop more cost-effective and high-performance water treatment systems as well as instant and continuous ways to monitor water quality as well. Nanotechnology in water applications potentially impacts on treatment, remediation, sensing, and pollution prevention. Nanotechnology for water treatment an
