Summary: An Ag@CeO2@Ti3C2 heterojunction was prepared by hydrothermal method, showing a bacteriostatic efficiency 2.96 times higher than pure CeO2 against E. coli and S. aureus. The heterojunction facilitated photoelectron transfer, inhibited carrier recombination, promoted reactive oxygen species production, and achieved a photocatalytic bacteriostatic effect, suggesting potential applications in CeO2 bacteriostatic fields and semiconductor modification.

Summary: Analysis of AlN epitaxial layers grown by molecular beam epitaxy (MBE) reveals the presence of Al-Al and N-N bonds, as well as a rough 3D-like structure. By employing low flux Al deposition in pulsed mode at the end of MBE growth, significant improvement in surface quality is achieved, leading to enhanced optical properties in Al0.85Ga0.15N/GaN multiple quantum wells (MQWs) growth. The introduction of pulsed low flux Al deposition shows a clear advantage in relative intensity between QW emission and low energy emission during photoluminescence studies.

Summary: Aqueous iron batteries have the potential for large-scale energy storage due to their safety and low cost. However, their long-term cycling stability is inadequate. In this study, cross-linked polyaniline (C-PANI) is proposed as a positive electrode active material to improve the electronical conductivity and electrochemical stability. The C-PANI, when combined with Fe metal negative electrode and Fe(TOF)(2) electrolyte, shows good specific capacity and discharge voltage after a high number of cycles. Mechanistic studies suggest that the bonding of Fe2+ ions to TOF- anions plays a role in the storage of charge.

Summary: The electronic properties of different thicknesses of antimonene were characterized, showing a certain sheet resistance and mobility under ambient conditions. Theoretical calculations suggest that topologically protected surface states play a key role in the electronic properties of antimonene. The study is expected to trigger further experimental research on topologically protected surface states in antimonene due to its simple structure and significant stability in ambient environments.

Summary: In nature, objects with rougher surfaces generally have higher friction coefficients, resulting in increased friction with contacting objects. The higher surface roughness of nanofillers dispersed in a matrix can enhance the energy dissipation capacity of composites. Comparative studies on composites reinforced with two types of graphene, reduced graphene oxide (rGO) and graphene oxide (GO), were conducted to assess factors including surface roughness, friction, dispersion, and specific surface area. The results showed that adding rGO/GO significantly increased the damping ratios of the composites. The research sheds light on the selection of graphene with high damping enhancement capabilities.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
