Abstract
Official abstract text for this publication.
Ion-doped metal or ceramic nanoparticles can be added into, for example, a component that upon exposure to an environmental stimulus, will release the ion and ‘tattle’ on any impending destruction.
First claim
Opening claim text (preview).
We claim: 1. A tattletale nanoparticle, comprising an ion-implanted nanoparticle that releases the implanted ion in response to a stimulus, and detecting the released implanted ions. 2. The tattletale nanoparticle of claim 1 , wherein the nanoparticle is implanted to a dose, of greater than 1 e 15 ions/cm 2 . 3. The tattletale nanoparticle of claim 1 , wherein the nanoparticle comprises a ceramic nanoparticle. 4. The tattletale nanoparticle of claim 3 , wherein the ceramic nanoparticle comprises beohmite, yttria, or ceria. 5. The tattletale nanoparticle of claim 1 , wherein the nanoparticle comprises a metal nanoparticle. 6. The tattletale nanoparticle of claim 1 , wherein the implanted ion comprises a noble gas. 7. The tattletale nanoparticle of claim 1 , wherein the implanted ion comprises an ionizable gas. 8. The tattletale nanoparticle of claim 1 , wherein the implanted ion comprises a reactive dopant or controlled ion alloy. 9. The tattletale nanoparticle of claim 1 , wherein the stimulus comprises a physical stimulus. 10. The tattletale nanoparticle of claim 9 , wherein the physical stimulus comprises heating the nanoparticle to above a release temperature. 11. The tattletale nanoparticle of claim 9 , wherein the physical stimulus comprises mechanical crushing. 12. The tattletale nanoparticle of claim 1 , wherein the stimulus comprises a chemical stimulus. 13. A method for non-destructive testing, comprising: providing a plurality of ion-implanted metal or ceramic nanoparticles in a component under test, exposing the component to an environmental stimulus, thereby causing the implanted ion to be released in response to the environmental stimulus, and detecting the released implanted ions. 14. The method of claim 13 , wherein the environmental stimulus comprises a physical stimulus. 15. The method of claim 13 , wherein the environmental stimulus comprises a chemical stimulus. 16. The method of claim 13 , wherein the released implanted ions are detected with a mass spectrometer. 17. The method of claim 16 , wherein the mass spectrometer comprises a sublimation pumped mass spectrometer.
