> While there has been widespread effort to develop self-healing materials that could mimic this ability of biological organisms, the researchers say, these have all required an active outside input to function. Heating, UV light, mechanical stress, or chemical treatment were needed to activate the process. By contrast, these materials need nothing but ambient light, and they incorporate mass from carbon in the atmosphere, which is ubiquitous. Mechanical stress, I wonder if such materials would serve well as coating atop an office floor to reduce the indoor co2. Every step that gets taken would activate the process. Probably won't make as much of a difference as a decent AC unit though.
