Development of Mg-Zn based alloys with rare earth (RE) element additions and with modified preparation processes domains the evolution of their potential structural applications. Nonetheless, their highest tensile yield strength (TYS) is still in the order of 400 MPa, clearly lower than that of the Mg-RE based alloys, in the order of 500 MPa, much less compared with the high-strength aluminum alloys and titanium alloys. According to many previous investigations, two relatively efficient methods to improve mechanical properties of ZK based alloys were revealed as: alloying by RE and optimizing wrought processes. However, comprehensive combinative investigation was hitherto not conducted to date. Thus, it is imperative in the next work to further improve the yield strength to the order of 500 MPa or much higher, and simultaneously modify the tension-compression strength asymmetry of the ZK series alloys. Maybe, developing novel wrought processes for ZK60 (+ RE) alloys or exploring appropriate pre-dealing treatments before or after the wrought processes might be an important approach to accomplish a much higher level of balance of high-strength and high-ductility.</p></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"2 2","pages":"Pages 151-166"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49726634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supercapacitors as the novel type of energy storage devices have the unique advantages, including the fast charging/discharging behaviors, high-energy/power density, and stable cycling performance. Compared with traditional supercapacitors, flexible supercapacitors are environmentally friendly, light weight, small size and high safety. Therefore, flexible supercapacitors have a wide application prospect in emerging electronic devices. Due to its flexibility, biocompatibility, and structure designability, cellulose and its gel materials are gradually used as electrodes, separators and electrolytes in flexible supercapacitors. Several construction processes at molecular scale for high-performance cellulose gels are summarized. Meanwhile, this review covers the recent progress of developing the flexible supercapacitors and all-in-one supercapacitors based on cellulose functional gels. We finally discussed the potential challenges and opportunities for cellulose and its derived materials in new-style flexible supercapacitors and other electronic devices.</p></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"2 2","pages":"Pages 177-188"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49726896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Potentiodynamic polarization curves and electrochemical impedance spectroscopy were used to study the corrosion behavior of the coated alloys. The results showed that when pH=2.5 and the chitosan concentration was 5.0 g/L, chitosan was deposited in the phosphate coating in the form of inclusions. In addition, the potentiodynamic polarization curves of the composite films show that the corrosion potential is positively shifted by 0.6 V compared to the monolayer phosphate coating, indicating improved corrosion resistance.
