Technology - Highway as Pollution Absorber

Some scientists at Eindhoven University of Technology, the Netherlands is currently developing a titanium dioxide-coated concrete can eliminate nitrogen oxides in the air.
Nitrogen oxide is the output of gasoline that is burned at high temperatures, which occurred in the automotive vehicle engine. This oxide can cause health problems such as shortness of breath.

In addition, nitrogen oxides are also responsible for other environmental issues, including the smoke haze and ozone damage. As quoted from BrightSide of News, August 15, 2010, the material used in concrete road use sunlight to convert nitrogen oxides to form nitrate, which clean the air.

Titanium dioxide, which is often found in paints, is capable of cleaning chemicals that will damage the self-algae and dust, making the road surface remain clean air while it being cleaned.

After some time successfully tested in the laboratory, coating materials have been used most streets in Hengelo, Netherlands. Some roads with similar wide left using ordinary concrete, and then the surrounding air samples were taken. Testing equipment found new material to prove that it is clean air.

Interestingly, the new material can also be combined with asphalt, if the roads were not wearing concrete. Exactly, it is more costly than uncoated material air purifier.

In a similar effort to find materials that antipollution researchers from China to develop nano-tech polymer. Although search technology to reduce, or eliminate impurities from the air continues to be done, we still have to find ways to reduce or eliminate sources of pollution.
