Diesel vehicles today emit fewer pollutants than older vehicles, thanks to a zeolite catalytic converter that was invented around 10 years ago. Although many groups have investigated this catalyst since then, it was still ...
In 1877, Charles Friedel and James Craft discovered a chemical reaction for quickly producing raw materials for plastics, fine chemicals and detergents. More than 100 years later, in 1994, the American George Olah won the ...
A diagnostic tool, similar in theory to those used by the medical profession to non-invasively image internal organs, bones, soft tissue, and blood vessels, could be equally effective at "triaging" extraterrestrial rocks ...
Known for their exceptional porosity that enables the trapping or transport of molecules, metal-organic frameworks (MOFs) take the form of a powder, which makes them difficult to format. For the first time, an international ...
A KAIST team made an ultra-fast hydrogen sensor that can detect hydrogen gas levels under 1% in less than seven seconds. The sensor also can detect hundreds of parts per million levels of hydrogen gas within 60 seconds at ...
Water has many ice phases that form under different pressure and temperature conditions. The effects of positive pressure have been explored extensively, with the results somewhat predictable: As the pressure increases, so ...
Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust.
Researchers at the US Department of Energy's Oak Ridge National Laboratory (ORNL) now have access to a cutting-edge capability for studying catalysts.
Cooking up biofuel
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory had just finished an experiment with a two-dimensional (2D) structure they synthesized for catalysis research when, to their surprise, they ...
