However, the existing Pb-basednmaterials suffer from a narrow X-ray absorbing range, high weight,nand rigidity. Inspired by the natural leaf, which can efficientlynabsorb light through chlorophyll and carotenoids in confined cells,nwe engineer ultralight and superelastic nanofibrous Bi&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;/Gd&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; meta-aerogels (BGAs) withnX-ray nanotrap arrays by manipulating the 3D confined assembly ofn1D Bi&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; and Gd&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; nanofibers.nThe BGAs can synergistically absorb X-ray photons from complementarynenergy ranges into the nanotraps and induce cyclic collisions withnBi&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; and Gd&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; nanofibers,nmaximizing the effective X-ray attenuation. The meta-aerogel exhibitsnthe integrated performance of efficient X-ray shielding efficiencyn(60–83%, 16–90 keV), ultralow density (10 mg cm&lt;sup&gt;–3&lt;/sup&gt;), and superelasticity. The production of these meta-aerogelsnpresents an avenue for the development of next-generation X-ray protectivenmaterials and the resolution of X-ray imaging systems.","PeriodicalId":522040,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147890263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
