This paper describes the pulse current electrodeposition (PCE) mediated preparation of Ni-W/TiN nanocomposites. Pulse current electrodeposition (PCE) was used to make Ni-W/TiN nanocomposites. The nanoindentation, wear, and corrosion of deposited Ni-W/TiN nanocomposites were studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The influence of pulse frequency (PF) and duty ratio on the shape, structure, phase structure, wear, and corrosion resistance of Ni-W/TiN nanocomposites was studied. When the duty cycle (DC) was 10%, the results demonstrated that a considerable number of fine grains were present on the deposited Ni-W/TiN nanocomposites, forming smooth, uniform, and fine organization. Increasing DC decreased the content of TiN nanoparticles in Ni-W/TiN nanocomposites. The content of TiN nanoparticles reduced from 11.3 wt % to 7.3 wt % by increasing the DC from 10% to 50%. In contrast, as the PF was increased, the TiN content in Ni-W/TiN nanocomposites increased. When the PF was increased from 50 Hz to 150 Hz, the TiN content increased from 6.4 wt % to 9.6 wt %, respectively. Furthermore, with a PF of 150 Hz and a DC of 10%, the produced Ni-W/TiN nanocomposites had an average hardness of 934.3 HV with ~39.8 µm of an average thickness. The weight loss of the Ni-W/TiN nanocomposites was just 17.2 mg at a PF of 150 Hz, demonstrating the excellent wear resistance potential. Meanwhile, the greatest impedance was found in Ni-W/TiN nanocomposites made with a DC of 10% and a PF of 150 Hz, indicating the best corrosion resistance.

“…The observed reflection may suggest the presence of a minor fraction of α‐SiC; nevertheless, no other reflections characteristic of α‐SiC were detected. This is most likely due to stacking faults within the [111] phase of cubic silicon carbide 5b,18 . Furthermore, the XRD of the SiC product reveals a small and broad peak in the 2‐theta range of approximately 20–25°; this may result from the presence of a small amount of residual amorphous carbon in our samples.…”

This study introduces a novel and versatile method for synthesizing honeycomb‐structured silicon carbide (SiC). The innovative approach utilizes a sucrose solution as the carbon source and nonporous silica spheres, which serve both as silicon precursors and templates, allowing for precise control over pore sizes. Notably, the process is characterized by its cost‐effectiveness, eco‐friendliness, and the utilization of milder conditions attributed to magnesiothermic reduction. The tunable pore sizes achieved through adjustments in the size of silica particles offer a versatile platform for customizing SiC materials to meet specific application requirements. Beyond its customizable nature, the method reduces the environmental footprint of SiC synthesis by utilizing eco‐friendly materials. Its combined attributes of accessibility, sustainability, and performance optimization underscore its potential for driving advancements in SiC‐based applications across various industrial and scientific domains.

The solid waste from solar photovoltaic (PV) systems diverges from carbon neutrality targets and the core principles of clean energy. Herein, we present an innovative and cost-effective strategy to fabricate P-SKW@C as anode materials based on the natural properties of submicron silicon kerf waste (SKW) by increasing the surface oxide layer and combining the synergistic effects of magnesium thermal and acid leaching. In particular, the carbon layer establishes channels for electron and ion transport, thereby enhancing the conductivity of P-SKW@C and the mobility of lithium ions. The formation of pores by the synergistic effects of magnesium thermal and acid leaching provides buffer space to accommodate the volume changes in silicon, ensuring the structural integrity of the electrode. Specifically, the P-SKW@C anode exhibits superior rate performance, reaching 1006 mAh g −1 at 2 A g −1 , and an outstanding reversible capacity of 1103 mAh g −1 with the current density returning to 0.2 A g −1 . Furthermore, the P-SKW@C anode demonstrates a remarkable specific capacity of 905 mAh g −1 at 500 mA g −1 over 200 cycles. Notably, the assembled LiFePO 4 //P-SKW@C full cell maintains a stable capacity of 105.96 mAh g −1 and an energy density of 329.84 Wh kg −1 at 0.5 °C after 50 cycles. This work introduces a new strategy for recycling the SKW in a sustainable, economical, and environmentally friendly way, facilitating the integration of solid waste and energy storage.
