There’s a class of materials responsible for the chemistry we rely on to make fertilizer for crops, create prescription drugs and refine oil into gasoline. They’re called catalysts, and they speed up chemical reactions and steer the direction of the changes that happen during the transformation from one chemical compound to another. Despite the fact that many catalysts are commonly found in biology (these catalysts are called enzymes), the chemistries of most catalysts are still not fully understood because of their complexity.
Argonne scientists and collaborators have identified another elemental actor in catalytic reactions that helps activate palladium while reducing the amount of the precious metal needed for those reactions to occur.

The world drinks a lot of wine, and that means a lot of grapes are consumed every year. But not every part of the grape ends up in the bottle. Seeds, stalks and skins — roughly a quarter of the grapes —- are typically discarded in landfills as waste. But now, researchers say they have found some useful commercial applications, such as prolonging the shelf life of fatty foods, for these wine leftovers.
The Colonial Pipeline, which carries fuel from Texas to New York, ruptured last fall, dumping a quarter-million gallons of gas in rural Alabama. By the time the leak was detected during routine inspection, vapors from released gasoline were so strong they prevented pipeline repair for days. Now, scientists are developing technology that would alert pipeline managers about leaks as soon as failure begins, avoiding the environmental disasters and fuel distribution disruptions resulting from pipeline leaks.
Setting off smoke bombs is more than good fun on the Fourth of July. The military uses smoke grenades in dangerous situations to provide cover for people and tanks on the move.
