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...

Atomic Layer Deposition of Nanoscale Materials for Energy Conversion

Marja N. Mullings
For a number of technologies, including microelectronics and energy conversion devices, feature sizes are becoming increasingly small, and the need for precise control over costly materials continues to grow. In addition to decreasing length scales, it is important that limited natural resources...

Improved Ethylene Cracking Furnace Control with Modern Process Mass Spectrometers

Mar 16, 2011
Peter J. Traynor
Whereas process mass spectrometers have been used as an alternative (lower cost) solution to multiple process gas chromatograph installations for many years, their use has been somewhat limited by their complexity - both real and perceived. The latest generation of process mass spectrometers has...
