Organic catalysts could greatly ease polymer recycling, reuse

Scientists from IBM and Stanford University have recent detailed polymer discoveries that could lead to the development of new types of biodegradable, biocompatible plastics. The result of a multi-year research effort, the breakthrough is based on organocatalysis, specifically oxide-based catalysts that show activities rivaling the most active metal-based catalysts. Harnessing this activity could enable us to significantly increase the ability to recycle and reuse PET.

Turning chemical manufacturing green

A new nanotech catalyst developed by McGill Univ. chemists offers industry an opportunity to reduce the use of expensive and toxic heavy metals. Although chemists have long been aware of the ecological and economic impact of traditional chemical catalysts and do attempt to reuse their materials, it is generally difficult to separate the catalyzing chemicals from the finished product. The team's discovery does away with this chemical process altogether.

Surface science goes inorganic

A collaboration between researchers at Northwestern Univ.'s Center for Catalysis and scientists at Oxford University has produced a new approach for understanding surfaces, particularly metal oxide surfaces, widely used in industry as supports for catalysts.

Visible light photocatalyst kills bacteria

Visible light photocatalyst kills bacteria

In the battle against bacteria, researchers at the Univ. of Illinois have developed a powerful new weapon—an enhanced photocatalytic disinfection process that uses visible light to destroy harmful bacteria and viruses, even in the dark.

Squeezing more out of a MOF

Squeezing more out of a MOF

What’s an MOF? It’s a metal-organic framework--a combination of metal and organic materials with molecular-scale pores that boast a high surface area and great potential for catalytic activity. Argonne Lab research into one promising example, ZIF-8, shows that such structures can be tailored to specific purposes by exerting industrially-accessible high pressure, changing the compound’s structure.

Ethanol-powered vehicles generate more ozone than gas-powered ones

Ethanol, often promoted as a clean-burning, renewable fuel that could help wean the nation from oil, would likely worsen health problems caused by ozone, compared with gasoline, especially in winter, according to a new study led by Stanford researchers.

First demonstrated metallic nanoparticles resistant to extreme heat

A Univ. of Pittsburgh team overcame a major hurdle plaguing the development of nanomaterials such as those that could lead to more efficient catalysts used to produce hydrogen and render car exhaust less toxic. The researchers reported the first demonstration of high-temperature stability in metallic nanoparticles, the vaunted next-generation materials hampered by a vulnerability to extreme heat.

Engineers image nanostructure of a solid acid catalyst

The catalytic processes that facilitate the production of many chemicals and fuels could become much more environmentally friendly thanks to a breakthrough achieved by researchers from Lehigh and Rice Univ. In an article the researchers report a novel electron microscopy imaging study of a tungstated zirconia solid acid catalyst. Based on new information obtained from these images, the researchers were able to design a preparation procedure that increased the activity of the catalyst by more than 100 times.  

Catalyst size does matter

Catalyst size does matter

Univ. of Utah chemists demonstrated the first conclusive link between the size of catalyst particles on a solid surface, their electronic properties and their ability to speed chemical reactions. The study is a step toward the goal of designing cheaper, more efficient catalysts to increase energy production, reduce Earth-warming gases and manufacture a wide variety of goods from medicines to gasoline.

Chemists defy the impossible and make stable carbenes

Chemists defy the impossible and make stable carbenes

Metal-carbene complexes are highly reactive molecular structures that are very useful in pharmaceutical labs for their catalytic abilities. Until now, chemists assumed reactive carbenes could not exist freely and almost required expensive, toxic metals as joining mechanisms. The breakthrough, which has resulted in stable reactive carbenes at room temperature in solid state and solution, should greatly benefit a wide array of catalytic processes.

Much ado about next to nothing

Much ado about next to nothing

The recent review of the past 10 years of the National Nanotechnology Initiative--as presented by the President's Council of Advisors on Science and Technology--suggested the rise of nanomanufacturing as the near future of nanotechnology. But the actual proposed funding reflects a cautious approach, even about nanotech in general.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.

P2i showcases liquid repellent nano-coating for hearing aids

At the AudiologyNOW! 2010 show in San Diego next month, UK-based coatings company P2i will display their relatively new Aridion liquid-repellant nano-coating. Designed for exposure to humidity or sweat, the polymer layer is applied by a pulsed ion gas process that lower’s the hearing aid’s surface energy, coaxing water away from delicate components.
