| 1 | Cellulose-based Antimicrobial Composites and Applications: A Brief Review显示文摘Cellulose-based antimicrobial composites,typically in the form of functional films and cloth,have received much attention in various applications,such as food,medical and textile industries.Cellulose is a natural polymer,and is highly biodegradable,green,and sustainable.Imparting antimicrobial properties to cellulose,will significantly enhance its applications so that its commercial value can be boosted.In this review paper,the use of cellulose for antimicrobial composites’preparation was discussed.Two different approaches:surface loading/coating and interior embedding,were focused.Three most widely-applied sectors:food,medical and textile industries,were highlighted.Nanocellulose,as a leading-edge cellulose material,its unique application on the antimicrobial composites,was particularly discussed. | Bo Sun Fangong Kong Min Zhang Weijun Wang Birat Singh KC Jimi Tjong Mohini Sain | 2019 | Paper And Biomaterials2019，4，4： | 5 |
| 2 | Squeeze casting of aluminum alloy A380: Microstructure and tensile behavior显示文摘A380 alloy with a relatively thick cross-section of 25 mm was squeeze cast using a hydraulic press with an applied pressure of 90 MPa. Microstructure and tensile properties of the squeeze cast A380 were characterized and evaluated in comparison with the die cast counterpart. Results show that the squeeze cast A380 possesses a porosity level much lower than the die cast alloy, which is disclosed by both optical microscopy and the density measurement technique. The results of tensile testing indicate the improved tensile properties, specifically ultimate tensile strength(UTS: 215.9 MPa) and elongation(Ef: 5.4%), for the squeeze cast samples over those of the conventional high-pressure die cast part(UTS: 173.7 MPa, Ef: 1.0%). The analysis of tensile behavior shows that the squeeze cast A380 exhibits a high tensile toughness(8.5 MJ·m-3) and resilience(179.3 k J·m-3) compared with the die cast alloy(toughness: 1.4 MJ·m-3, resilience: 140.6 k J·m-3), despite that, during the onset of plastic deformation, the strain-hardening rate of the die cast specimen is higher than that of the squeeze cast specimens. The microstructure analyzed by the scanning electron microscopy(SEM) shows that both the squeeze and die cast specimens contain the primary α-Al, Al2 Cu, Al5 Fe Si phase and the eutectic Si phase. But, the Al2 Cu phase present in the squeeze cast alloy is relatively large in size and quantity. The SEM fractography evidently reveals the ductile fracture features of the squeeze cast A380 alloy. | Li Fang Xue-zhi Zhang Bo-jun Xiong Henry Hu Xue-yuan Nie Jimi Tjong | 2015 | China Foundry2015，12，5： | 3 |
