Abstract Silk fibres exhibit good biodegradability, biocompatibility and balanced strength and toughness, which are useful for toughness/impact-critical composites in the biomedical field. However, the impact of hydration has not been studied for silk fibre-reinforced polymers (SFRPs). In this work, SFRPs fabricated vacuum-assisted resin infusion (VARI) were treated under three hydration conditions. A hydration condition of 40 °C at 89% relative humidity (RH) was sufficient to induce a reduction...

Abstract Biologically active scaffolds with tunable mechano- and bio-performance remain desirable for soft tissue engineering. Previously, highly elastic and robust silk fibroin (SF) scaffolds were prepared via cryogelation. In order to get more insight into the role of ethylene glycol diglycidyl ether (EGDE) on the structure and properties of SF scaffolds, we investigated the fate of SF scaffolds with different usages of the crosslinking agent in vitro and in vivo. Although SF scaffolds with va...

Abstract The transformation among MnII, MnIII and MnIV on the surface of the manganese oxides is a critical factor for peroxymonosulfate (PMS) activation. In this work, three kinds of Mn3O4 with different shapes (plate, cube and octahedra) were prepared to tune the surface Mn valence for ciprofloxacin (CIP) degradation, and the relationship between MnIV and PMS activation was established for the first time. The octahedral Mn3O4 (Mn3O4-O) owns high catalytic activity, MnIV is the primary active s...

Based on the investigated microstructure of different zones in the annealed automatic gas tungsten arc weld joint of TA16 and TC4 titanium alloys, the mechanical property of them was assessed under fatigue crack growth rate tests. For evaluation of fatigue crack growth rate, three points bending specimens were used. The correlation between the range of stress intensity factor and crack growth rate was determined in different zones of the annealed weld joint. Fatigue crack growth rates were obvio...

Abstract We consider a broad range of 13 BMGs from different alloy systems to represent the material class of bulk metallic glasses (BMGs) and characterize their fracture toughness. To determine the effect of composition on the fracture toughness within one alloy system, we consider Zr-Al-Ni-Cu and Pd-Ni-Cu-P BMG forming alloy systems, and series of systematically varied compositions Zrx(Al0.25Ni0.25Cu0.5)100-x (at.%) and Pdx(NiCu2)(80-x)/3P20. Sample preparation follows a thermoplastic forming ...

Abstract In this research, the effects of solid solution, peak aging (PA), over aging (OA) and retrogression re-aging (RRA) on microstructure, mechanical properties, and corrosion resistance of the spray-formed Al–Zn–Mg–Cu alloy were systematically and comparatively studied. It was found that after solid solution, most of the secondary phases dissolved into the α(Al) matrix and created a favorable condition for aging treatment. When the material was subjected to the RRA, the microstructure of th...

Abstract A series of TiO2 and γ-Fe2O3 co-doped graphene oxide (GO) nanosheets (xTiO2/γ-Fe2O3/GO) were prepared by a facile self-assembly method. The characterization results show that the xTiO2/γ-Fe2O3/GO have the advantages of narrow band gap energies (

High stiffness and strength carbon fibres are commonly used to reinforce epoxy-resin composites. While wild Antheraea pernyi silk fibres exhibit high toughness originating from their α-helix/random coil conformation structures and their micro-fibre morphology, their insufficient strength and stiffness hinders them from being used in similar structural composites. In this work, we use interply hybridization of silk and carbon fibres to reinforce epoxy-matrix composites. With increased carbon fibr...
