Scientists have created a fire retardant coating for wood. From the tree!

For coating production, researchers used HefCel technology (enzymatic fibrillation

high concentration cellulose). Having obtained a gel-like nanocellulose, the scientists applied it to wood.

Nanocellulose when applied to woodnaturally sticks to it and creates an airtight barrier that keeps oxygen from entering the wood. This helps protect the material from fire, the study says.

Previously scientists from the University of British Columbiahave developed cellulose nanocrystalline airgel, which will make bone implants easier, stronger and cheaper compared to similar products from hard ceramics.
