Craig Hill, Professor of Chemistry, and collegues from Emory University have for the first time combined an oxygen molecule with a platinum substrate.
The researchers work is significant, as it breaks the so-called "oxo-wall" barrier to create a stable chemically bonded stucture comprising of both
oxygen and platinum that was once thought impossible because oxygen is extremely unstable when combined with certain metals. Chemical bonds such as
this are commonly known as "metal-oxo species" and are found in many molecules and materials. Unfortunetly, up until now, metal-oxo species become
alot less stable the further to the right one looks on the periodic table. Until this breakthrough, attempts to create such species with elements such
as gold, silver and platinum have proven unsuccessful.
For the first time ever, Emory University researchers have broken through the so-called "oxo-wall" to create stable multiple chemical bonds between
oxygen and platinum – once thought impossible because oxygen is extremely unstable when combined with certain metals.
The breakthrough holds the potential for numerous applications in fuel cells, catalytic converters and emerging 'green' chemistry.

As the article states this is yet another once thought to be impossible barrier in the sciences, and good news for industry and greens alike as it
could usher in a new era of environmentaly benign compounds for both industrial and consumer use. I myself don't know what some of the applications
will be in the short term, but I do know its yet another breakthrough in the rapidly advancing realm of nanosystems and fabrication.
