| Z-contrast STEM shows how
'colossal conductivity' works
|
(Mon, 11 Aug 2008)
|
|
A new material characterized with ORNL's Z-contrast scanning transmission electron microscope could open a pathway toward more efficient fuel cells.
The molecular model of the ion-conducting material shows that numerous vacancies at the interface between the two layers create an open pathway through which ions can travel.
The material, a super-lattice developed by researchers in Spain, improves ionic conductivity near room temperature by a factor of almost 100 million, representing “a colossal increase in ionic conduction properties,” says Maria Varela of DOE's Oak Ridge National Laboratory, who characterized the material’s structure with senior researcher Stephen Pennycook.
