“…The presence of these nanoflakes is not observed for 200 °C and 400 °C sulfurization temperature. In different published works [23,[32][33][34][35], the NiS 2 -based 2D structures are reported to have high energy storage capabilities. Hence, these nanoflakes are strongly desirable to be present at supercapacitor structures.…”

“…Based on the SEM (figure 1), XRD (figure 2), and EDX analyses, the highest value of specific capacity is provided by the presence of the highest density of 2D-NiS 2 nanoflakes on the sample surface. It has been proven that the capacitive properties of 2D-structures based on NiS 2 are significantly higher compared to NiS [23,[32][33][34][35]. Therefore, it can be assumed that the dominant contribution to the capacitive behaviour of the NiS X samples originates from the presence of 2D NiS 2 nanoflakes.…”

“…The conventional fabrication methods of electrodes generally involve several complex steps using multiple expensive, or environmentally hazardous precursors (such as thiourea) and techniques [20][21][22][23][24][25]. Fabrication processes often involve mixing active materials with different additions as conductive materials and binders, which often causes a formation of electrochemically less active interfaces.…”

Nickel-based sulfides (particularly NiS2) are regarded as promising materials for highly efficient electrochemical generation and storage devices. The conventional fabrication methods of nanostructured NiSX electrodes involve several complex steps using multiple precursors and techniques. In this paper, the NiSX electrodes are prepared by a plain one-step process of one-zone sulfurization of Ni foam. The evolution of highly electroactive 2D-nanoflakes reliant on sulfurization temperature is studied. Scanning electron microscopy, X-ray diffractometry, and energy-dispersive X-ray spectroscopy confirmed the presence of NiSX (x = 1 and 2) in the prepared structures. A strong dependence of sample morphology and 2D-nanoflakes density on sulfurization temperature was demonstrated. The electrochemical properties of samples were characterized by cyclic voltammetry and electrochemical impedance spectroscopy measurements. Owing to the 2D-nanoflake structure, the NiS2 showed attractive electrochemical performance, including a high specific capacitance of 648 mF cm-2 and a capacitance retention rate of 90,7 % after 3000 cycles. Our study shows that the composition and crystal growth of NiSX can be tuned by reaction temperature during the sulfurization and high perspective of sulfurization in the synthesis of highly electroactive large-scale electrodes for supercapacitors.

With the advent of the intelligent era, the development of wearable devices has gradually attracted people's attention, and the demand for flexible sensors with the advantages of lightweight and portability has also increased significantly. The flexible sensors prepared by traditional methods have some disadvantages, such as limited ductility, poor durability, insufficient biocompatibility, weak mechanical properties, and complex manufacturing process. Compared with traditional materials, hydrogels have excellent flexibility, extensibility, fracture toughness, conductivity and biocompatibility, making them an ideal choice for flexible wearable sensors. The development of flexible hydrogel sensor is reviewed in this paper.

Due to the good reliability and long-term stability, self-healing hydrogels have emerged as promising soft materials for tissue engineering, smart wearable sensors, bioelectronics, and energy storage devices. The self-healing mechanism depends on reversible chemical or physical cross-linking interactions. Self-healing hydrogels with fascinating features (including mechanical performances, biocompatibility, conductivity, antibacterial ability, responsiveness, etc.) are being designed and developed according to the practical application requirements. In this review, the recent progress on self-healing hydrogels in their synthesis strategies and multiple applications is summarized. Their synthesis strategies involve reversible chemical or physical cross-linking processes or a combination of the two. Their recent applications include flexible strain sensors, supercapacitors, actuators, adhesives, wound healing, drug delivery, tumor treatment, 3D printing, etc. Finally, the current challenges, future development, and opportunities for self-healing hydrogels are discussed.
