Summary: Aqueous batteries based on zinc metal anodes have high potential for scalable energy storage due to their high specific energy, safety, and low cost. However, their limited cycling stability, particularly under high Zn utilization, has been a major challenge. To tackle this issue, a new inorganic/organic hybrid separator called P/FS-Z was designed, which exhibited balanced mass transfer capability and controllable interface reaction. The P/FS-Z separator achieved an ultrahigh accumulative deposition capacity of up to 12,000 mA h cm(-2) and a record long-term cycling life of 700 h at 80% Zn DOD. This research provides important guidance for the development and practical application of separators for aqueous metal batteries.

Summary: This review presents several cost-effective thin-film coating methods, including dip-coating, spin-coating, spray-coating, blade-coating, and roll-coating. Each method has its own advantages and disadvantages, and the selection of coating method should be based on the type and size of the substrate.

Summary: The influence of deposition pressure on the microstructure and mechanical properties of CVD TiAlSiN coatings was systematically studied. The results showed that increasing deposition pressure had a significant impact on the microstructure of the coating but minimal effect on the properties. The study also revealed the specific microstructures of different TiAlSiN coatings, providing inspiration for controlling the deposition parameters to achieve desired coating structures.

Summary: The research shows that increasing the atomic ratio of PtCo up to 1:3 significantly enhances the electrode activity for both membrane and gas diffusion layer, resulting in higher power densities. In contrast, the best performance for the cathode is achieved with 1:2 and 1:1 PtCo compositions on the membrane and gas diffusion layer respectively.

Summary: With the development of advanced reactors, improving the safety of nuclear reactors is crucial. This study developed a novel fuel pellet with zirconium-coated TRISO particles embedded in a zirconium metal matrix to enhance the ability to retain the release of fission products and achieve high thermal conductivity. The zirconium coating was deposited using fluidized-bed chemical vapor deposition (FB-CVD), and the consolidation process was achieved via spark plasma sintering (SPS). The effectiveness of the zirconium coating in preventing particle contact and cracking during sintering was confirmed through microstructure and mechanical property investigations.

Summary: The thermal stability of alpha-(AlxGa1-x)(2)O-3 films grown on c-plane sapphire substrates was explored through annealing at different temperatures. It was found that lower Al composition led to phase transformation to the most stable phase for Ga2O3, while higher Al composition improved thermal stability. Films with x = 0.45 maintained the corundum structure after annealing at 950 degrees C, while layers with Al contents above 0.6 remained stable and did not undergo phase transformation at 1100 degrees C.

Summary: Deep traps in n-type alpha-Ga2O3 grown by mist chemical vapor deposition are analyzed, revealing trap levels at approximately 2.0 eV, 2.5 eV, and 3.2 eV. The concentrations of these traps are lower than previously reported for alpha-Ga2O3, and a large Frank-Condon shift indicates a high degree of lattice coupling in the midgap state of alpha-Ga2O3.
