Thermotherapy is a widespread technique that provides relief for muscle spasms and joint injuries. A great deal of energy is used to heat the surrounding environment, and heat emitted by the human body is wasted on our surroundings. Herein, a woven Kevlar fiber (WKF)-based personal thermal management device was fabricated by directly growing vertical copper-nickel (Cu-Ni) nanowires (NWs) on the WKF surface using a hydrothermal method. The treated WKF was combined with reduced graphene oxide (rGO

In the last decades, fuel scarcity and increasing pollution level pave the way for an extensive interest in alternatives to petroleum-based fuels such as biodiesel, solar cells, lithium ion batteries, and supercapacitors. Among them, structural supercapacitors have been considered as promising candidates for automotive industries in present time. Herein, the use of carbon fiber-based supercapacitors in automotive applications is reviewed. Carbon fiber is an excellent candidate for vehicle body a

Abstract Energy consumption is increasing with the rapid growth of externally powered electronics. A vast amount of energy is needed for indoor heating, and body heat is dissipated to the surroundings. Recently, wearable heaters have attracted interest for their efficiency in providing articular thermotherapy. Herein, the fabrication of a personal thermal management device with a self‐powering ability to generate heat through triboelectricity is reported. Composites are prepared with vertically

This work describes the development of a woven carbon fiber and thermoset polyester resin based structural supercapacitor via three-dimensional (3D) printing. The specific surface area and capacitance of the electrodes were increased by hydrothermally synthesized N-doped Zn-Co selenide nanowires on the surface. The supercapacitor with N@ZnCoSe2-MXene exhibited an energy of 2.69 Wh kg–1, a power density of 43.20 W kg–1, and a Coulombic efficiency of 88.8% at 1000 mA g–1 of current density. The cy
