Rapid pair production: Detection of a new reaction path in the atmosphere

04-Apr-2018

Scientists have now observed a particularly rapid type of pair production in the laboratory: Hydrocarbons double when two peroxyl radicals react with each other. This means that stable products with the carbon skeleton of both peroxyl radicals are formed, which very likely will have a peroxide ...

What the Smell Can Tell

The degradation status of modern polymeric museum artifacts can be classified by their smell

08-Mar-2018

Breath analysis in disease diagnostics is a promising research field, and the advances in instrumentation allows the accurate detection of metabolites. But not only the health status of patients, but also the preservation status of museum artifacts could be monitored. Heritage science researchers ...

Rice U. sleuths find metal in 'metal-free' catalysts

28-Feb-2018

Detective work by Rice University chemists has defined a deception in graphene catalysts that, until now, has defied description. Graphene has been widely tested as a replacement for expensive platinum in applications like fuel cells, where the material catalyzes the oxygen reduction reaction ...

Better 'fingerprints' to detect elusive, valuable chemical compounds

28-Jun-2017

Imagine being able to see the entire Statue of Liberty and a small ant on its nose simultaneously. The drastic difference in size between the two objects would seem to render this task impossible. On a molecular level, this is exactly what a team led by Sandia National Laboratories chemists David ...

The inner lives of molecules

06-Apr-2017

Quantum mechanics rules. It dictates how particles and forces interact, and thus how atoms and molecules work -- for example, what happens when a molecule goes from a higher-energy state to a lower-energy one. But beyond the simplest molecules, the details become very complex. "Quantum mechanics ...
