Road Surface Purifies Air by Removing Nitrogen Oxides

Road surfaces can make a big contribution to local air purity. This conclusion can be drawn from the first test results on a road surface of air-purifying concrete, which reduces the concentration of nitrogen oxides (NOx) by 25 to 45 percent.

Oil Refineries Could Improve Energy Efficiency With New Method

Chemical plants spend from 50 to 70 percent of their energy in "separations," which are usually distillation steps required to separate a raw material into various products. An energy-efficient Purdue University method rearranges the distillation sequence needed to separate crude petroleum into products.
