Therefore, these materials hold a huge potential as the continuous power supply for wearable devices. Herein, we reported the preparation of a series of vinylene-linked triazole-cored covalent organic frameworks (COFs) by Knoevenagel condensation of 2, 4, 6-trimethyl-1, 3, 5-triazine as the core monomer. The as-prepared COFs tend to generate the nano- or micro-fiber morphologies with tunable lengths and diameters through changing the polyphenylene building blocks. Accordingly, these COF fibers could be readily composited with single-walled carbon nanotubes (SWCNTs) to form the flexible free-standing films upon a simple vacuum filtration method. A film sample containing 30 wt% g-C₁₈N₃-COF exhibited the highest power factor of 68.93 μW/(m K²) at 420 K. The manipulated 4-leg flexible thermoelectric generator (f-TEG) released a maximum output power and power density of 343.5 nW and 0.32 W/m² at a temperature difference of 35 K. After bending for 1000 times at a radius of 15 mm, the resistance change rate of the as-fabricated f-TEGs was less than 5%, exhibiting excellent stability and flexibility. This work might not only broaden the potential application scope of COF materials but also provide a new fabrication strategy towards energy harvesting.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"7 1","pages":""},"PeriodicalIF":16.1,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199921","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}

Harnessing the skin’s architectural blueprint, the dressing employs a three-layered structure with asymmetric wettability, fabricated via advanced electrospinning and screen printing techniques. Central to this design is the MXene@Sodium alginate (SA)/Polylactic acid (PLA) humidity sensor, mimicking a dermal environment with exceptional sensitivity (99%) and response time (0.6 s), ensuring sustained performance over 28 days. A chitosan sponge (CS) layer, incorporated by freeze-drying, optimizes exudate management and expedites healing. The outer layer, a hydrophobic PLA@Ag₃PO₄ membrane, offers robust antimicrobial efficacy by eliminating 99.99% of bacterial presence. Functionally, this outer skin analog doubles as an ultra-sensitive capacitive-type pressure sensor (199.22 kPa⁻¹), with impressive durability over numerous cycles (1500 cycles), capturing subtle pressure fluctuations as wounds heal. In vivo results show that the dressing can prevent infection, accelerate angiogenesis and epithelial regeneration, and significantly accelerate the healing of open wounds.

Currently, there is a deficiency in targeted regulation of these proteins. In this study, we introduce an oral approach for targeted modulation using electrospun core–shell short-fibers that settle on the intestinal mucosa. These fibers, designed for the controlled in situ release of phlorizin—a multi-transporter inhibitor—are crafted through a refined electrospinning-homogenizing process using polylactic acid and gelatin. Phlorizin is conjugated via a phenyl borate ester bond. Furthermore, a calcium alginate shell ensures intestinal disintegration triggered by pH changes. These fibers adhere to the mucosa due to their unique structure, and phlorizin is released in situ post-ingestion through glucose-sensitive cleavage of the phenyl borate ester bond, enabling dual-target inhibition of intestinal transporter proteins. Both in vitro and in vivo studies confirm that the short-fibers possess intestine-settling and glucose-responsive properties, facilitating precise control over transport proteins. Using models of hyperuricemia and diabetes in mice, treatment with short-fibers results in reductions of 49.6% in blood uric acid and 17.8% in glucose levels, respectively. Additionally, 16S rRNA sequencing indicates an improved intestinal flora composition. In conclusion, we have developed an innovative oral strategy for the prevention of hyperglycemia and hyperuricemia.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"44 1","pages":""},"PeriodicalIF":16.1,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199923","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}

Repairing osteoporotic bone defects is challenging due to decreased osteogenesis, increased osteoclast activity, and impaired angiogenesis. To address this challenge, a novel scaffold, inspired by the structure of multilayer fishing nets, is developed through a combination of template-assisted electrospinning and advanced three-dimensional (3D) printing technologies. The 3D nanofiber scaffold exhibits a hierarchical porous architecture. This design maintains the high specific surface area and extracellular matrix (ECM) mimicry of the nanofiber membrane. Additionally, the sparsely distributed nanofibers within the mesh-like structure facilitate cell infiltration. This unique topological configuration, particularly the strontium-hydroxyapatite (Sr-HAp)-enriched polycaprolactone/silk fibroin nanofibers, plays a critical role in synergistically promoting angiogenesis, enhancing osteogenesis, and suppressing osteoclast differentiation. In an osteoporotic cranial bone defect model, the scaffold demonstrates an exceptional repair efficiency of nearly 100% within 8 weeks, marked by significant new bone formation throughout the implanted area. In conclusion, our approach, which leverages intricate biomimicry and strategic active ion release, emerges as a highly promising strategy for repairing osteoporotic bone defects.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"2 1","pages":""},"PeriodicalIF":16.1,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199947","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}

To address this issue, a novel low-power-consumption coaxial electrophoretic display fiber (EPDF) with low-power-consumption, which consists of silver nanowire electrodes, electrophoretic microcapsule layer, polydimethylsiloxane (PDMS) encapsulation layer and PDMS substrate, was fabricated using a simple dip-coating method. The prepared fiber devices exhibit full functionality under a human-safe voltage of 30 V, featuring uniform and angle-independent contrast. Moreover, the EPDFs demonstrate excellent flexibility and mechanical stability, capable of operating properly at axial strains exceeding 50% and maintaining performance after 1000 cycles of 30% strain. The EPDFs, encapsulated with transparent PDMS, demonstrating exceptional wearability and biocompatibility. Benefiting from the distinctive bistable characteristics of electrophoretic microcapsule particles, EPDFs exhibit ultralow power consumption, and the varying light absorption capacities in different display states empower them to adapt effectively to diverse environments. These remarkable features qualify EPDFs for various outdoor wearable applications.

Here, an asymmetric wettability polyacrylonitrile (PAN) fiber (named Janus-PAN) with stable high surface potential via <i>in-situ</i> molecular confined modification is proposed for fog harvesting. By coupling the high capture efficiency generated by persistent electrostatic interaction and the directional self-driven transport supported by wettability gradient, Janus-PAN achieves a water collection rate (WCR) of 1775 mg/cm²/h, which is 2.6 times higher than that of fibers with low surface potential and no wetting gradient. Moreover, the potential application of the Janus-PAN harp in agricultural irrigation is demonstrated.
