Researchers have found a way to make carbon nanotube membranes that could find wide application as extra-fine air filters and as scaffolds for catalysts that speed chemical reactions. Rice ...

The new material is a bio-based hybrid foam, infused ... carbon dioxide from the amine solution for reuse. The material now presented avoids all of these problems. In future applications, filters ...

Despite direct air capture, which only accounts for a fraction of essential carbon reductions, attempts to improve its efficiency and scalability continue. The material's complicated manufacture ...

Briiv uses natural air filters made from coconut and a biodegradable “matrix filter” (a blend of carbon-infused hemp and a woolen microfiber), but the most apparent bio material is moss.
