Summary: The effects of various Gd additions on the microstructure evolution, tensile properties, and corrosion resistance of Mg-6Zn-0.5Ca-1Mn (ZMX6105) alloys were examined. The addition of Gd promoted the formation of Ca2Mg6Zn3 phase during solidification and inhibited dynamic recrystallization, resulting in the refinement of dynamic recrystallized grains and strengthening of basal texture. Additionally, the ZMX6105-0.2Gd alloy exhibited excellent tensile properties and optimal corrosion resistance in a 3.5 wt% NaCl solution.

Summary: Lean Mg-1.2Zn-0.3Ca-0.3Al-xMn (x = 0.25, 0.38, 0.5 wt%) alloys with different Al/Mn ratios were prepared using twin-roll casting technique. The formation of rhombohedral Al8Mn5 or cubic beta-Mn depended on the Al/Mn ratio. The alloy with Al/Mn>1.6 exhibited the lowest average corrosion rate (4.55 mm y-1) due to the lower Volta potential of Al8Mn5 compared to beta-Mn. The presence of fine Al8Mn5 weakened micro-galvanic corrosion and reduced stress concentration, resulting in admirable corrosion resistance and mechanical properties (UTS: -266 MPa, YS: -193 MPa, EF: -20%) for the alloy with Al/Mn>1.6.

Summary: This study focuses on the preparation of biodegradable calcium phosphate (CaP) ceramic coatings on self-designed Mg-2.0Zn-0.6Ca-xSi alloys through plasma electrolytic oxidation (PEO). The influence of calcium (Ca) and silicon (Si) on alloy microstructure, coating formation, and biomineralization mechanisms were investigated. The in vitro bioactivity and degradability of the CaP coatings were evaluated through immersion tests. The results suggest that the microstructure of the Mg-2.0Zn-0.6Ca-xSi alloys can affect the formation and growth of PEO coatings.

Summary: The reheating at high temperature was used to control the textural features in a rolled Mg-Zn-Ca-Mn alloy sheet. Reheating at 450 degrees C caused grain coarsening, leading to the formation of double twinning and shear bands during rolling. Unexpectedly, the basal texture became strong due to the non-uniformly distributed dislocations. On the other hand, reheating at 350 degrees C resulted in uniform deformation-microstructure and apparent texture weakening during post-annealing.

Summary: Biological materials, such as cell-derived membrane vesicles, have been used as alternative sources for molecular delivery systems due to their multicomponent features and easy-to-carry therapeutic agents. In this study, a red blood cell membrane (RBCM) vesicle-laden methacrylate kappa-carrageenan (KaMA) composite hydrogel was developed for soft tissue engineering. The hybrid hydrogels exhibited modified characteristics based on the content of RBCM vesicles, and showed controlled release of a hydrophobic drug molecule and support for cell growth.

Summary: In this study, poly(citric acid)-grafted graphene oxide (PGO) was incorporated into single-layer hollow fiber (SLHF) and dual-layer hollow fiber (DLHF) membranes to improve their antifouling properties during water treatment. The optimized PGO loading of 0.7 wt% in SLHF membrane resulted in higher water permeability and bovine serum albumin rejection compared to the neat membrane. Similarly, introducing 0.7 wt% PGO only to the outer layer of DLHF membrane improved its antifouling properties and increased the rejection rate of bovine serum albumin to 97.7%.

Summary: This study aims to synthesize MgZn/TiO2-MWCNTs composites with varying TiO2-MWCNT concentrations and investigate their mechanical, corrosion, and antibacterial properties. The results showed enhanced microhardness and compressive strength in the composites compared to the MgZn composite. Cell culture experiments demonstrated increased osteoblast proliferation and attachment with the addition of TiO2-MWCNTs, while corrosion resistance and degradation rate were also improved in the Mg-based composite. Antibacterial evaluations revealed that the composite showed antibacterial activity against Staphylococcus aureus. The MgZn/TiO2-MWCNTs composite has great potential for use in orthopedic fracture fixation devices.

Summary: To address the need for continuous monitoring and treatment adjustments in chronic diseases, a microneedle array technique is proposed to extract interstitial skin fluid (ISF) painlessly and bloodlessly. The molecular composition of ISF resembles blood plasma, making it a good choice for biomarker identification. The integration of a multiplexed sensor in the microneedle array enables rapid biomarker detection, allowing for practical and self-administrable monitoring and management of metabolic diseases.

Summary: Modifying polymeric membranes using ZIF-8 functionalized-2D nanofillers showed improved gas permeability and selectivity performance. The rGO/ZIF-8 and MoS2/ZIF-8 nanofillers were successfully synthesized and characterized. Addition of 10 wt% of each nanofiller to the PES solution resulted in MMMs with enhanced thermal stability. Compatibility between the 2D nanofillers and PES matrix was confirmed by FTIR and XRD analysis. The obtained MMMs exhibited significantly improved gas separation properties, demonstrating the potential of using 2D nanofillers for high-performance membranes.

Summary: In this study, the performance of membrane distillation (MD) was improved by coating MoS2-TiO2 on a PVDF-based hollow fiber membrane. The MoS2-TiO2/PP20 membrane showed enhanced hydrophobicity and porosity, leading to significantly improved MD performances. This work suggests that the MoS2-TiO2 coating can overcome the typical permeability/rejection rate trade-off effect and play a significant role in enhancing MD performances.
