Researchers at the Eindhoven University of Technology (EUT) may be on the brink of discovering a breakthrough that will lead to reduced pollution and cleaner air for all. According to the EUT, a roadway made of concrete blended with titanium dioxide can effectively remove up to 45 percent of the nitrogen oxides that it comes in contact with. The titanium dioxide, a photocatalytic material, captures airborne nitrogen oxides and, with the aid of the sun, converts it to nitrates that are harmlessly washed away by the rain. The EUT conducted real-world studies on a 1,000-square-meter section of repaved road in the Netherlands. Such testing showed that the laced pavement could reduce nitrogen oxides by 25 to 45 percent more than traditional concrete. As Jos Brouwers, professor of building materials at the EUT remarked, "The air-purifying properties of the new paving stones had already been shown in the laboratory, but these results now show that they also work outdoors." Additional testing is still underway and although the pavement laced with titanium dioxide does cost some 50 percent more than regular cement, overall road-building costs only increase by a marginal 10 percent. Costs aside, the advantages of the titanium dioxide are readily apparent, but the implementation of such a product requires repaving our roadways – a time intensive and costly endeavor.

Montreal projects get $17M The Gazette Published: Monday, June 16 International Science and Technology Partnerships Canada Inc. today announced $17 million in research and development funding to support three Montreal-based projects involving Canadian and Indian companies. Beneficiaries include CAE Inc., Pratt & Whitney Canada Corp. and McGill University, according to an announcement today by Foreign Affairs Ministers David Emerson. The three projects include the application of biofuels for aviation, the design and development of a new generation of regional transport aircraft and an improved system for storing dangerous materials in aboveground tanks. "Our government understands the importance of establishing international research partners and the critical role science and technology plays in the new economy," said Emerson. "These joint projects will enhance the collaboration between our scientists and commercialize their discoveries." http://www.canada.com/montrealgazette/news/business/story.html?id=d92f9f3c-9ed2-48f3-a340-ded06146a499
