I am glad to see another good article of yours. My first ever article on Steemit was an article about activated carbon in car filters to limit the level of PM2.5 in the busy road conditions, and I also use a huge activated carbon filter to filter the impurities and smell out of my drinking water.
The applications are also extended to space or Mars life support systems. Filtering or refiltering used water and gases from a Mars colony would tremendously help the development.
Keep it up and you will organically grow from here! And keep your eyes on the tools for analytical purposes :P
