Basically stripping lignin from trees to make an aligned fiber channel nannocellulose nanowood material, with anisotropic insulation properties. This spinout is marketing the stuff. Weird uses include blackening a top surface of an aligned block and floating it on a water surface, as a concentrated solar power receiver to make steam by capillary action through the aligned fibers.

So boiling wood in a sodium hydroxide/sulfide slurry to remove liglin and hemicellulose, then hot pressing the remains makes superwood that is as strong as steel due to densification of highly aligned cellulose nanofibers. Hot pressing also allows forming a final shape for engineered wood products.
