Chemists detect toxic emissions linked to catalytic converters in US
A study scheduled for publication in the Dec. 15 issue of the American Chemical Society's journal, Environmental Science and Technology, shows that for the first time, toxic metals emitted from automotive catalytic converters have been detected in urban air in the United States. view more (2005-12-06)
Platinum in Cardiff
Platinum from catalytic converters is collecting on the streets of Cardiff and moving through the city ending up in Cardiff Bay muds. New motor car technology means that precious metals are rapidly accumulating in the urban environment. Platinum is rapidly increasing in the urban environment since the introduction of catalytic converters on cars.... view more... (1998-09-02)
Increasing levels of rare element found worldwide
Dartmouth researchers have determined that the presence of the rare element osmium is on the rise globally. They trace this increase to the consumption of refined platinum, the primary ingredient in catalytic converters, the equipment commonly installed in cars to reduce smog. view more (2009-04-22)
Safe Heating of Explosive Gases
The Institut für Mikrotechnik Mainz GmbH (IMM) has developed the micro structured gas heater MSGH for combustible or explosive media. A clear separation of the space containing the medium from the heating elements allows safe heating and overheating of process gases, gas mixtures or gas/vapour mixtures. The MSGH has 50 cubic centimetres of... view more... (2004-06-23)
Danish researchers design the first virtual nano-catalyst in the world
Research offers new opportunities in the fields of renewable energy, pollution control and in the chemical industry. view more (2005-01-28)
New metal crystals, formed on a cotton assembly line
Appropriating cellulose fibers from cotton and crystallizing them, scientists at Pacific Northwest National Laboratory have grown never-before-seen configurations of metal crystals that show promise as components in biosensors, biological imaging, drug delivery and catalytic converters. view more (2007-03-27)
Russian Filter For Russian Exhausts
Automobiles manufactured in Russia are now often equipped with expensive American or European catalytic exhaust scrubbers - converters. However, according the opinion of researchers from the Mendeleyev Russian Chemical-Engineering University, Russian automobiles will be soon equipped with exhaust scrubbers manufactured in Russia. Traditional... view more... (2004-06-15)
CATALYTIC AND BATTERY MATERIALS - NEW RESEARCH FUNDED
The Leverhulme Trust has recently announced the funding of £488,000 for a programme of research into novel catalytic and battery materials, based at the Davy Faraday Laboratory of the Royal Institution. view more (1999-03-01)
Platinum nanocatalyst could aid drugmakers
Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. view more (2009-09-01)
Economical and cleaner cars with lean-burn catalytic converter
Dutch researcher Karen Scholz has taken a careful look at the properties of a new type of catalytic converter found in cars. view more (2007-07-13)
Revealing new applications for carbon nanomaterials in hydrogen storage
An international research team, involving Professor Rajeev Ahuja at Uppsala University and researchers in the USA, set out to understand the mechanism behind the catalytic effects of carbon nanomaterials. view more (2009-03-12)
Platinum nanocrystals boost catalytic activity for fuel oxidation, hydrogen production
A research team composed of electrochemists and materials scientists from two continents has produced a new form of the industrially-important metal platinum: 24-facet nanocrystals whose catalytic activity per unit area can be as much as four times higher than existing commercial platinum catalysts. view more (2007-05-04)
NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon monoxide (CO) into harmless carbon dioxide at room... view more...

Novel Chemistry for Ethylene and Tin
New work by chemists at UC Davis shows that ethylene, a gas that is important both as a hormone that controls fruit ripening and as a raw material in industrial chemistry, can bind reversibly to tin atoms. view more (2009-09-30)
Catalytic converter gets the pollution out of diesel engines
In the near future the usual summer ozone peaks exceeding the allowed threshold may be a thing of the past: the Paul Scherrer Institute (PSI) in Switzerland has developed a new type of catalytic conversion system, which filters nearly all nitrogen oxides out of diesel exhaust gases using a refined control technology. This eliminates the main cause... view more... (2004-09-08)
Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA world") and eventually to cellular life based on DNA... view more...

A touch of potassium yields better hydrogen-storage materials
An international research team, including Professor Rajeev Ahuja's research group at Uppsala University, has shown that small additions of potassium drastically improve the hydrogen-storage properties of certain types of hydrogen compounds. view more (2009-04-16)
Researchers Find Controls to Gold Nanocatalysis
Researchers at the Georgia Institute of Technology have made a discovery that could allow scientists to exercise more control over the catalytic activity of gold nanoclusters. view more (2006-08-10)
Detection of the "island effect" is solved
The "island effect" is one of the main problems in photovoltaic compound solar systems. The doctoral thesis of Pablo Sanchis, presented in the Public University of Navarre (Basque Country), proposes three main contributions: the first one is a new control strategy of a booster inverter for autonomous systems; the second one is a new... view more...
