To achieve this, short carbon fibers in an epoxy resin (ER) matrix were incorporated into the scales of an SLKF. The resulting textile is a highly stable protective composite that is flexible, warm, and thermally insulated. In addition, superior stab-resistance is ensured through rigid protective blocks in the R-SLKF, making up a hard overlapping scale region, besides satisfactory flexibility via soft twisted ultra-high-molecular-weight polyethylene yarn-based textiles. The R-SLKF achieves high stab resistance (peak load of approximately 600 N for a single scale thickness of 2 mm), good flexibility (~ 290 mN cm), and breathability (100 MPa, 423 mm/s), coupled with good warmth retention and thermal insulation properties (0.28 ℃/s), which are superior to previously reported protective composite textiles. From the results, the combination of desirable individual protection, excellent wearability and comfort enables human beings to survive in extremely dangerous environments. Finite element simulations provided valuable insights into the factors influencing the stab resistance of R-SLKF and elucidated the underlying anti-puncture mechanism in accordance with the experimental findings. This study presents a novel strategy for the facile industrial fabrication of flexible and lightweight protective composite textiles, which is expected to enhance the structure and material design for future innovations and provide advantages for personal protective equipment in various industrial fields.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"6 4","pages":"978 - 992"},"PeriodicalIF":17.2,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140563723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed soft actuators capable of color change and programmable shape morphing using elastic fibers with a liquid metal core. Once the hollow elastic fiber with the thermochromic pigment was fabricated, liquid metal (gallium) was injected into the core of the fiber. Gallium has a relatively low melting point (29.8 °C); thus, fluidity and metallic conductivity are preserved while strained. The fiber can change color by Joule heating upon applying a current through the liquid metal core and can also be actuated by the Lorentz force caused by the interaction between the external magnetic field and the magnetic field generated around the liquid metal core when a current is applied. Based on this underlying principle, we demonstrated unique geometrical actuations, including flower-like blooming, winging butterflies, and the locomotion of coil-shaped fibers.

Currently, orthotopic liver transplantation is the sole clinical treatment for ALF, but its wide usage is severely limited due to donor shortage and immunological rejection. An emerging and promising technology for ALF treatment is liver tissue engineering (LTE), wherein porous scaffolds serve as a crucial component. Nanofiber scaffolds, which mimic the inherent structures of fibrous extracellular matrix well, provide an ideal environment for cell growth and tissue regeneration. Recently, several functional nanofiber scaffolds for LTE have been developed, which show impressive results in regulating cell function and repairing liver injury when combined with appropriate seeding cells and/or growth factors. This review firstly introduces the etiologies and treatment indicators of ALF. Subsequently, typical fabrication technologies of nanofiber scaffolds and their related applications for function regulation of liver-related cells and treatment of ALF are comprehensively summarized. Particular emphasis is placed on the strategies involving an appropriate combination of suitable seeding cells and growth factors. Finally, the current challenges and the future research and development prospects of nanofiber scaffold-based LTE are discussed. This review will serve as a valuable reference for designing and modifying novel nanofiber scaffolds, further promoting their potential application in LTE and other biomedical fields.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"6 3","pages":"686 - 712"},"PeriodicalIF":17.2,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140563809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work provides a simple and scalable technique for constructing fast ion conductor nanofibers (FICNFs) and poly-m-phenyleneisophthalamide (PMIA) nanofibers synergistically enhanced polyethylene oxide (PEO)-based composite solid electrolytes (CSEs) for ASSLMBs. The FICNFs, which were mainly composed of high loadings of ZrO₂ or Li_6.4La₃Zr_1.4Ta_0.6O₁₂ nanoparticles, had a percolated ceramic phase inside the nanofibers, while the exposed nanoparticles formed continuous organic–inorganic interfaces with the PEO matrix to enable Li⁺ transport. The interfacial transport rate between ZrO₂ and PEO was calculated as 4.78 × 10^–5 cm² s⁻¹ with ab initio molecular dynamics (AIMD) simulations. Besides, the PMIA nanofibers provided strong skeletal support for the CSEs, ensuring excellent mechanical strength and safety for thin CSEs even at high temperatures. More importantly, the amide groups in PMIA provided abundant hydrogen bonds with TFSI⁻, which lowered the lowest unoccupied molecular orbital (LUMO) level of lithium salts, thus promoting the generation of lithium fluoride-rich solid electrolyte interphase. Consequently, the modified CSEs exhibited satisfactory ionic conductivities (5.38 × 10^–4 S cm⁻¹ at 50 °C) and notable Li dendrite suppression (&gt; 1500 h at 0.3 mAh cm⁻²).

With the <i>in-situ</i> CsPbI₂Br crystallization during electrospinning, annealing-free and photoelectroactive γ-CsPbI₂Br can be achieved.

CsPbI₂Br-PVAc nanofibers obtained under the optimal electrospinning condition: high-electrospinning voltage (25 kV) and low-solution supply rate (0.02 mm/min), show more uniform morphology, increased stability, and extended photoluminescence decay time. These nanofibers enable the construction of photo-sensing yarn devices, capable of generating a photovoltage of around 180 mV and current density of 17 mA/cm² upon illumination by a 532 nm pulsed laser, while maintaining a remarkable ambient stability of 16 days.
