“It's been a scarce collector's item until a couple of months ago, when AMT Ertl reissued it, albeit still in its photoactive molding and lacking the internal lighting fixtures or nacelle engines of the original.”
“Nanosolar ceo Martin Roscheisen, who, like many new solar kings, has roots in Silicon Valley, says he can achieve radical cost savings by directly applying photoactive chemicals with an ink composed of nanoparticles.”
“Coated with a few dozen nanometers of a photoactive film, Pilkington's new Activ sic glass effectively cleans itself, as natural radiation from sunlight chemically reacts with organic dirt deposits on the surface.”
“Essentially, the orthicon was a pickup tube that used a low-velocity electron beam to scan a photoactive mosaic.”
“One area to watch in particular is photoactive plastics, nanoscale material capable of generating an electrical charge from light, said Matthew Nordan, vice president of research at nanotech consulting firm Lux Research.”
