|Ruthenium<!-- I get a feeling this one might be outdated - seems likely that ruthenium could be phased out by now, since 'dye sensitized' doesn't sound like it would need a specific rare mineral. Keep in mind that the paper was published in 2000, and although it was updated in 2020, maybe they kept this just because it was the only row? Idk just a wild guess. More research needed? --> | |Ruthenium<!-- I get a feeling this one might be outdated - seems likely that ruthenium could be phased out by now, since 'dye sensitized' doesn't sound like it would need a specific rare mineral.
