Participants at an expert meeting on ethics of nanotechnologies in the Arab region, which was organized by the United Nations Educational, Scientific and Cultural Organization (UNESCO)'s Cairo and Doha offices and took place from May 18-19 in Doha, Qatar, called for the creation of an Arab council...
Researchers from the University of California Los Angeles (UCLA) in the U.S. have developed a new reverse osmosis membrane made from a cross-linked matrix of polymers and engineered nanoparticles that can draw in water particles while repelling contaminants, an innovation that the researchers say can...
This blog entry says that advanced nanotechnology can potentially improve the efficiency of water distribution in developing countries, specifically in agriculture. The entry quotes an article from the Associated Press entitled <a href="http://www.forbes.com/home/feeds/ap/2006/03/18/ap2604848.html">Water...
Thailand’s state-run National Nanotechnology Center has used the recent flooding in the country as an opportunity to show how nanotechnology-based products could help mitigate the impact of future natural disasters. One product is the nano-sack, or N-sack, which is similar to a giant, superabsorbent...
Irrigation is a critical component of agriculture in the United States, and with climate change scenarios predicting that most regions of the country will only get hotter and drier, farmers will need to get smarter about when and how they irrigate. Alan Lakso, a crop physiologist at Cornell University,...
Researchers at the London Centre for Nanotechnology (LCN), United Kingdom, and an international team of scientists, have discovered a structure that may be step toward the development of new materials that could be used to seed clouds and cause rain. The structure, a one dimensional ice chain built...
Researchers from the Massachusetts Institute of Technology (MIT) in the U.S. have developed a material that exhibits water-attracting (hydrophilic) and water-repelling (hydro-phobic) characteristics on a single surface, a discovery which they say could be used for collecting water in arid regions of...
Water scarcity is already an issue for 600 million people in the world today, and that number is expected to grow, depending upon future rates of population growth, to between 2.7 billion and 3.2 billion people by 2025. The problem is not the lack of water on the planet, but the fact that most of it...
The Science and Development Network, SciDev.net, a free-access website that provides reliable and authoritative information about science and technology for the developing world, launched yesterday a spotlight focused on whether nanotechnology can provide solutions to water treatment in the developing...
A new study by Helmut Kaiser Consultancy says that the global market for nanotechnology in water and wastewater was worth US$1.6 billion in 2007 and is anticipated to reach US$6.6 by 2015. The article says, “Nanotechnologies will produce huge environmental benefits in terms of water management...
