Learning from Nature: Scientists Break Down Carbon Dioxide Into Carbon Monoxide Using Visible Light Mar 10, 2010
The enzyme is more robust than other catalysts, willing to facilitate the conversion again and again ... "We looked for a way that seems like nature's way of doing it, which is more efficient." Armstrong notes that "essentially it shows what is possible were we to be able to mass-produce a catalyst with such properties." ... Carbon monoxide also has significant fuel value and readily can be converted by known catalysts into hydrocarbons or into methanol for use as a liquid fuel. (Science Daily)

Fiberdome settles air pollution civil case Mar 5, 2010
The complaint also alleged Fiberdome used a chemical catalyst that was not allowed under its permit. To its credit, Van Hollen noted, Fiberdome has taken steps to significantly reduce its emission of styrene and to come back into compliance with its air pollution control permit.

Seeing in numbers Mar 3, 2010
They are degraded by ever-present Ras deactivator proteins, like RasGAP. My calculations suggested that, even after stimulus was withdrawn and free active Ras proteins were degraded by RasGAPs, active Ras molecules could stay bound to SOS, thereby maintaining a more active catalyst than if the cell had not been previously stimulated thus demonstrating a short-term memory of activation or hysteresis (see graphic below) ... Although my past research on polymers and catalysts was interesting, my... (The Scientist)
Stellar, Metal-Free Way to Make Carbon Nanotubes Feb 27, 2010
Unlike current methods for producing carbon nanotubes -- tiny yet strong structures with a range of applications in electronics and, ultimately, perhaps even medicine -- the new approach does not need the aid of a metal catalyst ... These observations surprised Kimura because carbon nanotubes are typically grown with platinum or another metal as a catalyst, yet Nuth's reaction had used no metals. (Science Daily)

Ghana Oil II - Transforming the Ghanaian Economy Feb 10, 2010
The Atta-Mills administration envisages that the oil and gas reserves [will] serve as catalyst for the commercial exploitation of our other natural resources that have either not been exploited, or exploited but not processed into high value products for domestic use and exports. The gas resources will be used to support energy-based industries, such as glass bottles, steel mills, aluminum smelting and rolling mill operations which have faced serious challenges from the high cost and...

New Perspective for Understanding the Mechanisms of Catalytic Conversion Feb 10, 2010
Despite being one of the most studied catalytic processes, the exact mechanism of interaction between the carbon monoxide molecule and the catalyst, often platinum, is not fully understood. An important step in the reaction is the adsorption of CO on the surface of the catalyst ... A team of scientists from the ESRF and the ETH in Zurich (Switzerland) has managed to see how the electrons in the platinum reorganize as the adsorption is taking place and why catalysts are "poisoned," i.e. why their...

How Five Scientists Will Use Stimulus Funds Jan 29, 2010
A critical hurdle to be surmounted, she says, is to design and synthesize the perfect electrode, "one that does not degrade and which is a very efficient catalyst for the chemical reaction that [a] fuel cell is designed to operate with.". "Computational experiments can shed light where experiments cannot give accurate enough information. What I'm proposing to do is not only modeling the quantum mechanical processes that are the source of the energy provided by fuel cells, but [also] do this on... (BusinessWeek)
