This review focuses on the advanced design and optimization of nanostructured zinc–air batteries (ZABs), with the aim of boosting their energy storage and conversion capabilities. The findings show that ZABs favor porous nanostructures owing to their large surface area, and this enhances the battery capacity, catalytic activity, and life cycle. In addition, the nanomaterials improve the electrical conductivity, ion transport, and overall battery stability, which crucially reduces dendrite growth on the zinc anodes and improves cycle life and energy efficiency. To obtain a superior performance, the importance of controlling the operational conditions and using custom nanostructural designs, optimal electrode materials, and carefully adjusted electrolytes is highlighted. In conclusion, porous nanostructures and nanoscale materials significantly boost the energy density, longevity, and efficiency of Zn–air batteries. It is suggested that future research should focus on the fundamental design principles of these materials to further enhance the battery performance and drive sustainable energy solutions.

Although thermosetting polymer materials have excellent mechanical properties, they are less self-healing, recycling than thermoplastic polymer materials, which may cause a serious waste of resources. Herein, a series of polyurea materials with high mechanical strength, good properties of self-healing and recycling are prepared by adjusting the ratio of polyether polyol and introducing disulfides into the synthesis of polyurea prepolymer in an innovative way.The composite polyurea (FHPUA) materials with tensile strength over 47 MPa and elongation at break of 720% are prepared. The experimental results show that by adjusting the content of aromatic disulfide, the tensile strength is further increased to 52 MPa, and the heat resistance of the material is improved. Through five self-healing experiments, the surface of the material recovers as before even after continuous heating at 70 C for 1 h. In addition, the tensile strength of the material recovers 86.56% and the elastic modulus recovers 70.21% after four recycling experiments. In practical application, it is expected to fill the shortcomings of traditional polyurea such as micro cracks, short service life and poor performance, and have great potential applications in the fields of coating layer of heavy-duty conveyor belts, encapsulation film of electronic devices and building facade coating.disulfide bonds, high mechanical properties, polyurea, recycling, self-healing | INTRODUCTIONPolyurea, made from polyisocyanate and polyamine, belongs to a branch of polyurethane materials, which is an excellent synthetic polymeric material. The polar bonds such as urea bonds, 1,2 ester bonds, 3 and ether bonds 4 provided excellent mechanical properties, heat resistance, and solvent resistance to polyurea materials. In addition, the three-dimensional structure by the crosslinking reaction also makes the performance of polyurea materials more excellent. 5 It has been widely used in electronic devices, 6,7 aerospace, 8 rail transportation, 9,10 construction, 11,12 and so on. However, in practical application, it will be damaged to different degrees under the stimulation of light, heat, radiation, and external force, which will not only affect the service life of the material, but also cause safety problems. Therefore, self-healing polyurea materials emerged at the historic moment and set off a research boom. [13][14][15][16][17] The mechanism of action of self-healing polyurea materials benefits from the dynamic reversible reactions of the system, which are generally divided into dynamic covalent interactions, such as disulfide bonds, 18-20 ester bonds, 21 borate ester bonds, 22,23 acyl hydrazone bonds, 24,25 and noncovalent interactions, such as hydrogen bonding, 18 ionic interactions, 26 and host-object interactions. 27 As we know from the bond energy, the bond energy of disulfide bond

In this study, operando photoelectron spectroscopy was used to characterize the performance of graphene field-effect transistors under working conditions. By sweeping the back-gate voltages, the carrier concentration of the graphene channel on the 150 nm Si3N4/Si substrate was tuned. From the C1s core level spectra acquired under the application of different gate voltages, the binding energy shifts caused by electric-field effects were obtained and analyzed. Together with the C1s peak shape information and the photoluminescence spectrum of the Si3N4/Si substrate, the presence of local potential across the X-ray beam spot associated with defects and gate leakage current in amorphous Si3N4 was identified. The presence of defects in Si3N4/Si substrate could not only screen the partial electric field generated by the back gate but also serve as long-range scattering centers to the carriers, thus affecting charge transport in the graphene channel. Our findings will help further investigate the dielectric/graphene interface properties and accelerate the utilization of graphene in real device applications.
