This article explores nanotechnology approaches to water purification, an application of nanotechnology that advocates suggest could contribute to solutions for some of the major problems faced globally, such as ensuring safe drinking water for a growing population, as well as addressing issues in medicine,...
Helmut Kaiser Consultancy has released a study of the global water disinfection, treatment, and purification markets, including the opportunities and risks associated with recent nanotechnology and molecular technology innovations for water disinfection and purification. The report summary says that...
Recent developments in membrane technology, an increasingly important method of water filtration, are largely based on advances in nanotechnology. Membrane-based methods of water filtration include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. The use of nanomaterials in these...
Researchers from the Atomic Research Centre in India are researching how carbon nanotubes could enable simple and easy to use water filtration systems that remove arsenic, fluoride, heavy metals, and toxic organic contaminants. According to the researchers, carbon nanotube-based water purification systems...
U.S.-based Applied Nanotech, Inc., a subsidiary of Nano-Proprietary, Inc., will receive US$1 million through the 2006 Defense Appropriate Bill to continue developing its PhotoScrub™ concept, a "thin film coating on a flexible fiberglass cloth that decomposes pollutants at the molecular level...
Researchers from the Toyota Central Research and Development Laboratories in Japan have developed a new porous manganese oxide nanomaterial embedded with gold nanoparticles that they report can effectively remove volatile organic compounds (VOCs) and nitrogen- and sulfur oxides, which are potentially...
The ICPC-NanoNet project, an European Union (EU) funded project that brings together partners from the EU, China, India, Russia and Africa with the goal of providing wider access to published nanoscience research and opportunities for collaboration, has announced an online workshop, "Nanotechnology...
U.S. company Applied Nanotech, Inc. (ANI) has been awarded federal funding to further develop PhotoScrub®, a thin film photocatalytic coating on a flexible fiberglass cloth that causes pollutants in gases and liquids to decompose at the molecular level. The funding will be used to develop a prototype...
Researchers from Rensselaer Polytechnic Institute in the U.S. have found a method for using low-voltage electricity to control the flow of water through nanotubes, a finding which could lead to new near-instantaneous desalination technology. Nanotube membranes provide high flow rates and high selectivity,...
This article explores research being conducted within the nanotechnological field to improve water membrane technologies.  Water purification membranes are used in many applications, with a variety of different types currently under development.  While no membrane can filter and purify water...
