suggests that treated wood may serve as an ideal
The researchers used rattan wood, which is similar to bamboo in composition
, but more pliable, and thus commonly used in furniture.
Heating the wood,
then exposing it to carbon dioxide and oxygen, caused it to turn into porous calcium carbonate
. Then it was converted to hydroxyapatite
using a phosphate donor
Other ways to replace bones include ceramics
, metal, and bone from cadavers. However, like previous attempts at calcium carbonate bone replacements, these methods tend to be brittle
and do not always adequately fuse
with existing bone. Other upcoming methods for replacing bones include bone printers
The authors state that this research could have implications for building space vehicles
, as the resulting material is strong and tough, and maintains its properties under high heat and mechanical stress.
