The limited folding resistance of continuous silicon carbide (SiC) fibres hinders their application as flexible, foldable materials. With this objective in mind, the folding endurance and damage properties of the second (2nd) and third (3rd) generation continuous SiC fibre tows were investigated through repeated folding tests, optical microscope observation and tensile tests. These SiC fibre tows were disassembled from two-dimensional (2D) SiC fibre braided fabrics with varying braiding angles. The braiding process can alleviate the force on fibre tows during the textile forming process. The investigation of damage mechanisms and analysis of force conditions are instrumental in optimizing structural parameters. The research findings suggested that, in comparison to the 3rd generation continuous SiC fibres, the 2nd generation SiC fibre tows demonstrated higher resistance to repeated folding. In contrast, the 2nd generation fabrics exhibited slightly lower folding endurance values. After repeated folding, the SiC fibre tows in fabrics showed the highest strength losses near the braiding angle of 37.8° to 38.3°. In comparison, the SiC fibre fabric demonstrated the lowest folding endurance values (approximately 760 times) near the braiding angle of 41° to 42°. Considering factors such as folding endurance value, the strength loss rate of fibre tows and fabric strength loss rate, it can be concluded that SiC fibres in fabrics with large braiding angles exhibit optimal performance in terms of folding endurance.

The combination of one-dimensional carbon nanotubes and two-dimensional transition metal carbon/nitride (MXene), using the electrochemical deposition method and the hydrothermal method to deposit manganese dioxide (MnO2) on the surface of the composite fiber. The results indicated that the fiber supercapacitor deposited by electrochemical deposition has a higher volumetric specific capacitance than the fiber supercapacitor deposited by hydrothermal method. The specific capacitance at a current density of 1 A/cm³ is about 97.5 F/cm³. After 2 500 cycles of charging and discharging, its final capacitance retention rate is about 74.5% of the original.

Hydrogels are widely used in wound dressings due to their moisturizing properties and biocompatibility. However, traditional hydrogel dressings cannot monitor wounds and provide accurate treatment. Recent advancements focus on hydrogel dressings with integrated monitoring and treatment functions, using sensors or intelligent materials to detect changes in the wound microenvironment. These dressings enable responsive treatment to promote wound healing. They can carry out responsive dynamic treatment in time to effectively promote wound healing. However, there is still a lack of comprehensive reviews of hydrogel wound dressings that incorporate both wound micro-environment monitoring and treatment functions. Therefore, this review categorizes hydrogel dressings according to wound types and examines their current status, progress, challenges, and future trends. It discusses various wound types, including infected wounds, burns, and diabetic and pressure ulcers, and explores the wound healing process. The review presents hydrogel dressings that monitor wound conditions and provide tailored treatment, such as pH-sensitive, temperature-sensitive, glucose-sensitive, pressure-sensitive, and nano-composite hydrogel dressings. Challenges include developing dressings that meet the standards of excellent biocompatibility, improving monitoring accuracy and sensitivity, and overcoming obstacles to production and commercialization. Furthermore, it provides the current status, progress, challenges, and future trends in this field, aiming to give a clear view of its past, present, and future. [ABSTRACT FROM AUTHOR]

As interest in smart textiles grows, fiber-based supercapacitors are gaining attention as promising devices for powering wearable electronics. Herein, we have demonstrated a two-step manufactured hybrid fiber with excellent energy storage properties. Anhydrous MXene (Ti3C2Tx) sheets are primarily spun in synergy with liquid crystal carbon nanotubes (CNTs) to produce a continuous fiber as a promising electrode material, which solves the problem of poor rate capability owing to the sheet re-stacking of MXene. MnO2@MXene/CNT fibers are subsequently prepared by electrochemical deposition with controlled time. The optimal content of MXene (10 wt%) and a perfect thickness of the MnO2 layer (4 μm) are testified to achieve an excellent capacitance of 371.1 F cm−3 in three-electrode system, which is about 200% and 1800% higher than that of 10 wt%-MXene/CNT and CNT fiber electrode, respectively. Symmetric fiber supercapacitor is assembled by paralleling two fibers with LiCl/PVA gel electrolyte, manifesting a superior cycling stability of 86.3% after 10000 cycles. Anhydrous MXene nanosheets and CNTs are incorporated by a high yield spinning technique to prepare continuous hybrid fibers as a conductive framework for MnO2 deposition, exhibiting stable and outstanding energy storage properties in supercapacitor.

Summary: All‐solid‐state flexible supercapacitors (FSCs) are promising energy‐storage devices in wearable smart electronics. Carbon cloth (CC) has emerged as an ideal candidate as it can fulfill all the required properties for conductive, corrosion‐resistant, and lightweight FSC substrates. However, commercial CC is difficult to adhere to without crosslinkers and binders owing to the hydrophobic surface. Herein, oxygen plasma and chemistry methods are selected for hydrophilic modification of commercial CC. Then, Ti3C2Tx flakes are coated on the surface of modified CC as active materials. These modified morphologies were characterized by scanning electron microscope and mechanical properties were investigated by a fabric tensile tester. The electrochemical properties of the MXene‐based electrodes by two modification methods were compared. Chemistry modification CC/Ti3C2Tx electrode exhibits an areal capacitance of 513 mF cm−2, which is 88% higher than that of oxygen plasma‐modified CC/MXene electrode, and capacitance retention remains above 92% after 10 000 cycles. This work proposes a feasible strategy, offering a platform for rational designs of flexible electronics based on textiles, as well as employing a large family of MXenes and their heterostructures.

Objective To analyze the distribution and drug resistance of pathogens isolated from patients in intensive care units (ICU) and non-ICU, so as to provide evidence for clinical anti-infective treatment and promote rational antibiotics use. Methods Inspection samples and drug susceptibility test results of patients in ICU and non-ICU from the whole year of 2013 were compared and analyzed retrospectively. All the data were statistically analyzed by using the WHO NET5.3 software and EXCEL. Results 1. There were 469 strains of pathogenic bacteria isolated from patients in ICU.3715 strains were isolated from patients in non-ICU. 2. The most common pathogens in ICU were Acinetobacter baumannii (Aba), extended-spectrum β-lactamase-producing Klebsiella pneumoniae (Esk) and Enterococcus faecium (Efm). 3. The most common pathogens in non-ICU were extended-spectrum β-lactamase-producing Escherichia coli (Esd), Escherichia coli (Eco) and Klebsiella pneumonia (Kpn). 4. ICU strains resistant rate was generally higher than the non-ICU. ICU separation of Aba resisted for most β-lactam antibiotic and the rate was greater than 80%, significantly higher than non-ICU department. Conclusions The resistant of ICU isolates is in serious condition. Hospital should strengthen the supervision and management of clinical antimicrobial drug use to control nosocomial infection and reduce bacterial resistance. [ABSTRACT FROM AUTHOR]

The ubiquity of wearables, coupled with the increasing demand for power, presents a unique opportunity for nanostructured fiber-based mobile energy storage systems. When designing wearable electronic textiles, there is a need for mechanically flexible, low-cost and light-weight components. To meet this demand, we have developed an all-in-one fiber supercapacitor with a total thickness of less than 100 μm using a novel facile coaxial wet-spinning approach followed by a fiber wrapping step. The formed triaxial fiber nanostructure consisted of an inner poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) core coated with an ionically conducting chitosan sheath, subsequently wrapped with a carbon nanotube (CNT) fiber. The resulting supercapacitor is highly flexible, delivers a maximum energy density 5.83 Wh kg−1 and an extremely high power of 1399 W kg−1 along with remarkable cyclic stability and specific capacitance. This asymmetric all-in-one fiber supercapacitor may pave the way to a future generation of wearable energy storage devices. [ABSTRACT FROM AUTHOR]

This study investigates the mechanical properties of Polyurethane Bark Gum (PBG) reinforced with Solid Glass Beads (SGBs) of varying diameters and content. The tensile analysis demonstrates that a 1% SGB volume fraction maximizes tensile stress and fracture elongation due to synergic composite effects, with smaller SGBs enhancing interfacial adhesion and reducing microcrack formation. The impact analysis revealed that the addition of SGB reduced the impact strength due to interface delamination and energy dissipation mechanisms, with optimal impact resistance observed at a particle size of 0.4–0.6 mm and a content of 5%. Morphological characterization was conducted using optical microscopy, scanning electron microscopy, and synchrotron radiation CT scanning techniques, highlighting the role of SGB in toughening, crack bridging, and stress shielding. This study provides insights into the performance of PBG/SGB composite materials and guides the material design for specific applications. [ABSTRACT FROM AUTHOR]
