Wound infection is a worldwide health issue that not only brings large detrimental effects to people's physical and mental health, but also causes substantial economic burdens to society. By using traditional surgical debridement and antibiotic therapy, patients generally suffer more pain and are at risk of recurring infections. Thus, the development of non-antibiotic treatment methods is desperately needed. Currently, the emerging of flexible wound dressings with physiological signal detection, inactivated infectious pathogen, and wound-healing promoting properties has exhibited immense potential for the treatment of infected wound. Among various dressings, MXene‐based flexible electronic materials as wound dressings with special electroactive, mechanical, photophysical, and biological performances possess a broad application prospect in healthcare. In this review, the challenges of infected wound management are introduced. Next, the types of MXene-based flexible materials and wound infection features are outlined. Then the recent advance of MXene-based flexible materials for infected wound detection and treatment is summarized. Lastly, the predicaments, prospects, and future directions of MXene-based flexible materials for infected wound management are discussed. [ABSTRACT FROM AUTHOR]

Existing concrete-filled steel tubular (CFST) structures are mostly based on cast-in-situ concrete construction technology. The beam-column joint emphasizes the horizontal connection, while the vertical connection of columns is mostly based on a steel tube connection instead of a precast CFST column connection; this is detrimental to the control of the concrete pouring quality and the full assembly of the structure. Thus, the investigation of an assembly joint that enables the full connection between the beam and CFST column is the key to the improvement of the construction quality and the promotion of the development of the assembled structure. This work proposes an assembly joint between an H-shaped steel beam and a CFST column, and the seismic behavior of the joint was investigated by low-cycle loading experiment. The finite element model of the joint was then established by the numerical analysis method. After verifying the rationality of the finite element model, the influences of both the endplate thickness and the bolt diameter on the energy dissipation performance of the joint were investigated via parametric analysis. The results reveal that with the increase of the endplate thickness and the bolt diameter within a certain range, both the bearing capacity and energy dissipation capacity of the joint will be improved. Moreover, the cooperative bearing mechanism of the column connector and concrete can be fully exerted. Thus, these conclusions indicate the feasibility of the use of the proposed assembly joint in practical engineering applications. Finally, the mechanical mechanism of the assembly joint was studied, and the calculation formula of the joint bending capacity was proposed. [ABSTRACT FROM AUTHOR]
