Oxygen/Combustible Safeguards in Low Nox Fired Heaters

Mar 22, 2010
Edward M. Marszal
Refineries have been installing low NOx equipment on their fired heaters in response to tighter environmental regulation. Low NOx burners minimize air ingress in locations other than directly at the burner, and internally recirculate flue gas in the heater firebox. They operate on much narrower...

Chem Economics
T. Kevin Swift
Not all polymers are useful and/or processable in their natural form. Thus, functional chemicals are added to polymer resins to facilitate processing and to enhance, extend, or otherwise modify the properties of the plastic products manufactured from polymer resins. Such plastic additives represent a $4.6-billion business in the U.S.

Rapid Deposition of Titania Nanoparticles for Dye Solar Cells

Oct 18, 2011
Rocco Panella
Dye-sensitized solar cells (DSSCs), while only having been designed about twenty years ago, are considered to be one of the most promising third-generation solar cell technologies among experts. One of the key features of DSSCs is a mesoporous, 10 micron layer of titania nanoparticles which acts as...

Ordered Mesoporous TiO2/ZnO Material for Hydrogen Production

Oct 17, 2011
Menan Hussein
Ordered mesoporous Zr-doped TiO 2 /ZnO material is currently being investigated for band gap tuning and higher loadings of photo-sensitizer. Utilization of such mesoporous materials thereby offers an opportunity to sensitize semiconductor with higher sensitizer loadings leading to effective charge...
