The steady-state creep rates at 750°C are at least two orders of magnitude lower than those of some nickel-based superalloys and heat-resistant steels.

The strength of densified <em>4CL1</em> knockout wood closely matched that of traditionally treated wood (320.2 ± 3.5 MPa), demonstrating the effectiveness of genetic modification in creating sustainable, high-performance engineered wood and contributing to reduced CO<sub>2</sub> emissions and environmental conservation.</div></div>","PeriodicalId":388,"journal":{"name":"Matter","volume":"7 10","pages":"Pages 3658-3671"},"PeriodicalIF":17.3,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141918730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
