Random skin flaps are commonly used to cover thick skin wounds. However, necrosis frequently occurs when the flap's aspect ratio exceeds 2:1. Promoting angiogenesis and regulating inflammation are essential for treating ischemia–reperfusion injury in random flaps. In this study, calcium-doped silica nanoparticles loaded with deferoxamine (CD) were created through physical adsorption by rapidly mixing biodegradable calcium-doped silica nanoparticles (CS) with deferoxamine (DFO). A gelatin methacryloyl (GM) hydrogel nanofiber scaffold containing 1% (w/v) CD (GM/CD-1) was subsequently produced using electrospinning technology. The GM/CD-1 scaffold showed excellent biocompatibility and significantly promoted flap regeneration in mice, achieving a 96.17 ± 3.17% flap survival rate at 14 days. Additionally, it effectively stimulated hair follicle growth and exhibited an inflammatory-modulating effect. These features suggest that the GM/CD-1 scaffold could be valuable for clinical applications in flap regeneration and other tissue engineering fields. © 2025 The Wound Healing Society.

Colorimetric sensors have applications in gas monitoring due to their simple and quick detection through visible color changes. However, it remains challenging to prepare colorimetric sensors with high sensitivity. Herein, this work fabricated a biomass-based colorimetric sensing yarn with high sensitivity using anthocyanins as the colorimetric dye and wool powder as an effective ammonia (NH3) adsorbent. The sensitivity of the prepared yarns was evaluated for detection limit and response time. Surprisingly, the addition of 3% wool powder greatly improved the sensitivity of the prepared yarns, with a reduction of both detection limit and responsive time from 100 ppm to 20 ppm, and 2 min to 20 s, respectively when exposed in 150 ppm NH3. The prepared yarns also showed good selectivity and reusability. An example of the practical use of colorimetric yarns was presented. This work provides a facile strategy for fabricating wearable devices for toxic gas monitoring with visual output. © 2024, The Authors. All rights reserved.

Temperature variation is a key factor in clothing design. It is important to monitor the temperature variations of human skin and clothing in real time under different exercise levels. Herein, using an innovative wearable monitor, the variations of skin temperature and clothing temperature during exercise under different conditions were explored. It was proven that the clothing temperature variation trend was almost the same as the human skin temperature variation, but relatively extreme conditions would lead to different temperature variations on human skin and clothing during exercise. The temperature difference between neighboring clothing layers was greater than that between the upper and bottom sides of a single layer. In addition, the temperature difference between adjacent layers of clothing varied from different clothing types. The results and experimental apparatus provided will provide the research basis for the development of comfortable sportswear.

The depletion of freshwater resources has become a major global concern. Various promising solar evaporation systems have been proposed;however, they face challenges in terms of adaptability, versatility, and simplicity, which limit their industrial feasibility. To enhance the efficiency of interfacial solar steam evaporation systems based on carbon fibers and utilize industrial technology, a carbon-cotton fabric (CCF) with a well-defined structure was successfully developed through traditional textile weaving techniques. This fabric can be easily processed into different shapes, including flat (CCF-), V-shaped (CCF-V), W-shaped (CCF-W), and O-shaped (CCF-O) structures, allowing for variations in solar thermal evaporation rates and efficiencies. This method provides a strategic approach for investigating the impact of shape on solar thermal evaporation behavior. The experimental data show that the CCF-O sample exhibited a favorable photothermal evaporation rate of 2.29 kg m-2 h-1. Subsequently, the diameter of CFF-O was adjusted to achieve an optimal balance between the water delivery and evaporation rates to improve the solar utilization efficiency. An evaporator with a diameter of 4 cm achieved an evaporation efficiency of 150.3%. This moldable fabric demonstrates promising potential for use in desalination and wastewater purification, offering a unique opportunity to enhance the efficiency, versatility, and portability of solar evaporation technologies. © 2024, The Authors.

The rapid development of next-generation portable electronic devices urgently requires lightweight and multifunctional electromagnetic interference (EMI) shielding materials with robust performance and high durability in harsh conditions, yet it remains extremely challenging. In this work, porous carbon fibers (PCFs) featuring the interconnected nano-scaled pores on surface and the internal micron-sized pores, were prepared and stacked into multi-layer carbon films, that further introduces the in-of-plane porous network and out-of-plane interlayer space. Such multi-scaled porous structure brings beneficial effects to carbon films including low density, consecutively conductive pathway, and excellent electromagnetic wave absorption capability. . As a result, the resulting carbon films demonstrate an impressive EMI shielding effectiveness up to 90 dB in the X band at a very low density of 0.19 g cm-3, presenting shielding performance superior to commercial metal counterparts, as well as significantly outperforming most of the reported carbon-based EMI shielding materials. Furthermore, the stacked carbon films are structural stable and robust, capable of delivering high EMI shielding performance tolerance to extreme environments, like acid/basic treatments, cryogenic (-196 °C) or high (250 °C) temperatures, and hygrothermal environment. Additionally, as-fabricated multi-layer carbon films demonstrates outstanding adsorption capacity for organic solvents and charge storage capacity. This study offers a facile yet feasible strategy for preparing advanced materials to address the EMI problems of next-generation electronic devices in a more economical and environmentally friendly manner. © 2024, The Authors.

Interfacial solar evaporation plays a crucial role in desalination because of its sustainable, eco-friendly characteristics. However, major challenges to simultaneously achieving salt rejection, fast evaporation, and heat localization in solar desalination devices still remain. We propose a photothermal textile with vertically confined water layers for scalable, high-flux, long-term-reliable solar desalination. The photothermal textile consists of outer layers (carbon fibers) for solar absorption and core layers (hollow yarns) for water-feeding channels. Three-dimensional evaporators possess large evaporation areas and, thus, high evaporation rates, and the vertically confined water layers in the hollow yarns enable natural convection for effective salt rejection with negligible heat loss. Consequently, this photothermal textile achieves an evaporation rate of 2.05 kg m⁻² h⁻¹ in high-salinity brine (15 wt % NaCl solution) under 1-sun irradiation, with long-term reliability of over 20 days in continuous outdoor operation. © 2025 The Author(s)

Traditional ionic conductive hydrogel is prepared by chemically crosslinking the polymer chanins to form network. However, the chemically crosslinked ionic conductive hydrogel usually showed limited elongation at break and high hysteresis during stretching process. Here, a simple strategy of synthesizing ionic conductive hydrogel without crosslinking agent was purposed. Hydrophilic salt in the ionic conductive hydrogel not only act as the ion supplier, but also provide the spatial confinement effect to form the completely physically crosslinked hydrogel. Firstly, CaCl2 was used as the representative salt. The optimal PVA/PAM/CaCl2 ionic conductive hydrogel (PPC), showed excellent tensile performance (2400.3±140.63%), anti-freezing performance (-28.8 oC), high conductivity (4.8±0.01 S/m), excellent stability in room temperature, low hysteresis, and high transparency. The conductivity of PPC showed no sensitivity to the tensile strain..This innovative combination enables PPC ionic conductive hydrogel to have extraordinary versatility. The flexible all-solid-state supercapacitor assembled with PPC ionic conductive hydrogel as the electrolyte has a high area specific capacitance (136.9 mF/cm2). The prepared supercapacitor can maintain good stability under certain tensile deformation (The capacitance retention rate was 87.7% when stretched at 200%). Moreover, other high hydrophilic salts including LiCl, ZnCl2, MgCl2 and AlCl3 were used to prepare ionic conductive PVA/PAM hydrogel to verify the universality of this preparation method. © 2024, The Authors.

The development of multifunctional textiles is essential for applications of wearable portable electronics, artificial intelligence, military, healthcare, and communication industry. Herein, an asymmetric multifunctional flexible conductive AgNWs@PET/PA composite nonwoven with excellent EMI shielding and effective joule heating performances is proposed by depositing a thin AgNW network on a PET/PA nonwoven using a facile and scalable spray-coating approach. Due to the high air-pressure force and the hydrogen bonds between AgNWs and PET/PA matrix, AgNWs are tightly deposited on the surface of the nonwoven without adhesive and overlapped with each other to form an effective network. With a low content of 6 wt% AgNWs, the EMI shielding efficiency of the composite nonwoven can reach 41.19 dB in the X-band, which is due to the multiple internal reflection and absorption of the incident waves by the conductive AgNWs network as well as the porous structure of the nonwoven. Moreover, the AgNWs@PET/PA composite nonwoven shows excellent joule heating performance from room temperature to 115.5 ℃ at a low applied voltage of 2.5 V in seconds. Furthermore, the addition of reversible thermochromic inks further verified the excellent joule heating performance of the composite nonwovens and provide a possibility for the preparation of visual temperature monitoring intelligent clothing. Therefore, the scalable AgNWs@PET/PA composite nonwovens are considered promising alternatives in a wide range of applications in electromagnetic shielding and thermal management. © 2023, The Authors.
