Summary: This study proposes the incorporation of manganese oxide into carbon matrix magnetic composites to enhance the electromagnetic wave (EMW) absorption properties. Multiple interfacial ternary-component Fe3C/MnO/Nitrogen-doped carbon (NC) absorbers were synthesized through facile hydrothermal, oxidative polymerization, and carbothermal reduction processes. The designed composites exhibit excellent EMW absorption properties, with an effective absorption bandwidth of 4.88 GHz (13.12-18 GHz) at a mere thickness of 1.5 mm. The outstanding performance of EMW absorption can be attributed to effective modulation of electromagnetic parameters through a large number of heterogeneous interfaces, defects, and magnetic loss. Meanwhile, adjusting the filling ratios of the composites in the absorber can significantly adjust the electromagnetic parameters of the samples. This work presents an effective approach for the preparation of high-performance EMW absorbers with ternary components, as well as a strategy for developing novel broadband absorbers that are lightweight and have thin thickness.

Summary: TiO2/Au/BDD composites with a Z-scheme structure were prepared by depositing gold and titanium dioxide on the surface of a boron-doped diamond film. The introduction of Au improved the contact resistance and carrier transport efficiency, while also enhancing the surface Hall mobility of the BDD electrode. The Z-scheme structure facilitated fast electron and hole combination, promoting efficient separation of electrons and holes under photoirradiation. These modifications significantly enhanced the electrocatalytic performance of the electrode and improved pollutant degradation efficiency, especially for the TiO2/Au/BDD-30 electrode.

Summary: Core-shell structured SiO2@MoS2 nanospheres were prepared via hydrothermal method, with MoS2 nano-sheets irregularly growing on the outside surface of SiO2. The microstructure and EM wave absorption properties of SiO2@MoS2 nanospheres were explored. SiO2@MoS2 achieved a minimum reflection loss (RLmin) value of -49.35 dB with a thickness of 2.8 mm, and an effective absorption bandwidth (EAB) of 7.44 GHz. The remarkable EM wave absorption performance could be attributed to the interfacial polarization from the core-shell structure and multiple reflections on MoS2 ultrathin nanosheets, as well as the effective impedance matching provided by the combination of SiO2 and MoS2.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
