A biocompatible bone graft for implanting into a bone wound site or screening a bone disease drug, comprising a porous scaffold structure made from a tannin-hydroxyapatite resin, a population of osteocompetent stem cells, and a growth medium. Methods of synthesis and physical characterization of the porous scaffold structure are described, as well as biological testing of the osteocompetent stem cells of the bone graft.

Bone graft with a tannin-hydroxyapatite scaffold and stem cells for bone engineering

A thermo-set resin composition comprising a Quebracho wood tannin extract, a furfuryl alcohol, a neoprene compound, a dimethicone, polyethylene glycol, abrasive particles, and a glycerol phosphate acidic ester and/or graphite. Further, a method of preparing the thermo-set resin composition including mixing Quebracho wood tannin extract with a furfuryl alcohol to form a primary mixture, adding additives and abrasive particles to the primary mixture, and reacting the primary mixture by adding a catalyst. The thermo-set resin composition is molded into a shape under heat and pressure to a Brinell hardness 8.5 daN/mmand 48 daN/mmand can be incorporated into a friction pad of a brake pad.
