Utrecht chemists prove Nobel Prize-winner Olah correct

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 ...

NASA investigates use of medical-like tools to study samples of the solar system

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 ...

When a porous solid retains its properties in liquid form

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 ...
