Mostly through sheer coincidence, I have been running across several articles (see below) regarding approaches to NOx emissions control. The latest comes from a new paper in the International Journal of Applied Ceramic Technology (DOI: 10.1111/j.1744-7402.2010.02539.x)…

Titania–concrete combination in roadways reduces NOx levels 25-45%

By / July 24, 2010

Credit: TU/e Earlier this month, Jos Brouwers, a professor of building materials at Eindhoven University of Technology (Netherlands), reported that tests on a new stretch of roadway in the municipality of Hengelo indicate that concrete coated with titanium dioxide can significantly cut residual NOx automobile emissions, a major source acid rain and smog. In a…
