Description
Jiahui Shi and co-authors engineer in 2026 a zinc alloy meant to fix load-bearing bones and then dissolve once healing is done. Adding trace rare-earth elements to a zinc-lithium-manganese base created internal phases with a mixed grain structure. The resulting material reached a tensile strength of 772 megapascals and bending strength of 1,207 megapascals, close to medical titanium.
Those same phases even out the alloy's breakdown, releasing zinc ions at a controlled rate rather than in bursts. The tuned ion levels switched on the Rap1 signaling pathway in bone-forming cells. Implants of the alloy produced about twice as much new bone as titanium implants in the team's tests. The authors present the zinc-lithium-manganese-yttrium alloy as a degradable alternative to permanent metal fixation for demanding orthopedic repairs.
