When boiler equipment does not meet state or federal emissions requirements, operators may require after-treatment systems. After-treatment systems contain emissions control catalysts, depending on ...

With stricter emissions standards, low back pressure requirements, and 100,000 mile durability specifications, ceramic catalysts have undergone significant developments over the past few years. The ...

FTP and ECE + EUDC emissions are measured from six converters having similar restriction and platinum group metals on two 1999 prototype engines/calibrations. A 2.2L four cylinder prototype vehicle is ...

Since their discovery in 1991, researchers have made steady progress in CNT synthesis methods. Early techniques like arc discharge and laser ablation could produce small quantities of high-quality ...
