Higher-density batteries, more efficient thin-film solar cells, and better catalysts may all soon be possible, thanks to a new technique that allows nanowires to be “decorated” with nanoparticles. Using the novel technology, scientists from Stanford University have been able to festoon the outside surfaces of nanowires with intricate chains of metal oxide or noble metal nanoparticles, thereby drastically boosting the effective surface area of the nanowires. Other researchers have previously tried to achieve the same end result, but apparently never with such success.
