Summary: This study successfully developed superelastic organic/inorganic composite aerogel scaffolds by blending silica nanofibers and poly (lactic acid)/gelatin nanofibers. In vitro experiments showed that the released silicon ions from the scaffolds promoted the differentiation of stem cells into osteoblasts and enhanced bone-related gene expressions. Additionally, the silicon ions also facilitated the proliferation of endothelial cells and the expression of vascular endothelial growth factors, promoting angiogenesis. The assessment in a rat calvarial defect model demonstrated the potential of these scaffolds to induce bone regeneration and promote osteogenesis and angiogenesis.

Summary: This study proposes a strategy for fabricating highly stable and luminescent all-inorganic CsPbBr3@PVDF-HFP/PS nanofibers. Bright-emitting CsPbBr3 nanocrystals were successfully encapsulated within the polymer nanofibers by optimizing the electrospinning parameters, perovskite precursors, and ligands. Additionally, the nanofibers' hydrophobic surface structure formed through the hydrolysis and condensation of PFDTMS under moist conditions. The CsPbBr3@PVDF-HFP/PS nanofibers demonstrated improved stability due to the double protection of the polymer matrices and hydrophobic PFDTMS oligomers.

Summary: In this study, three types of flexible 3D-interconnected carbon nanofibers were prepared and used as substrates for vertically grown ultrathin MoSe2 nanosheets. The resulting composites were employed as freestanding anodes for lithium-ion batteries, with the hollow multi-nanochannel structure of NHMCFs delivering the highest capacity after 400 cycles at 1 A g-1. The multi-nanochannel structure in NMCFs and NHMCFs helps alleviate volume changes during charge-discharge processes, while the uniform coating of MoSe2 nanosheets on NHMCFs increases mass loading and capacity.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
