Summary: In this study, a Co@CuFe2O4 absorbing agent was obtained through ball-milling assisted chemical precipitation and annealing method, which showed excellent impedance matching at thin thickness. The composite possessed sufficient interface polarization ability and eddy current loss due to the contact between CuFe2O4 NPs and Co. The broadband microwave absorption of the composite was also contributed by dipole polarization, electron hopping/conduction, and structural scattering. The preparation method reported here can be referenced for manufacturing electromagnetic absorbers with outstanding performance.

Summary: Transition metal dichalcogenides (TMDs) have unique structures and electrical properties, making them highly advantageous for electromagnetic wave (EMW) absorption. Despite significant research on TMD-based EMW absorbers in the past three years, comprehensive summaries are rare. Therefore, it is important to discuss the interaction between morphologies, structures, phases, components, and EMW absorption performances of TMD-based absorbers. This review analyzes TMD-based absorbers from the perspectives of EMW absorption regulation strategies and the latest progress of TMD-based hybrids as EMW absorbers, summarizing absorption mechanisms and component-performance dependency.

Summary: Ni-Co/PC composite is prepared by introducing metal Co element with Ni-MOF/PC as precursor. Then a series of Ni-Co bimetal/PC composites are prepared by polyaniline coating, oxidation reaction, and vulcanization reaction. It is found that vulcanization reaction was the best path for the electromagnetic wave absorption performance of the product. The minimum reflection loss (RLmin) of NiCo2S4/PC composite reaches - 67.81 dB at the sample thickness of 2.6 mm, and the maximum effective absorption bandwidth (EAB) reaches 6.16 GHz when the sample thickness is 2.1 mm. NiCo2S4/PC composite is an ideal electromagnetic wave absorber due to its excellent electrical conductivity, rich surface, and high attenuation capability.

Summary: In this study, two-dimensional NiCeOx nanosheet-modified carbon nanotubes (CNTs) composites were prepared via hydrothermal method. The addition ratio of nickel salt and cerium salt was adjusted to form NiCeOx with different morphologies, and the introduction of CNTs effectively prevented the aggregation of NiCeOx nanosheets. Microstructural analysis revealed that hexagonal NiCeOx nanosheets with a size of 100 nm were uniformly intertwined with CNTs. The NiCeOx/CNTs composites exhibited superior electromagnetic wave absorption performance compared to pure CNTs and NiCeOx nanosheets, attributed to improved impedance matching and multiple polarization relaxation.

Summary: This study explores the effects of different particle sizes of lead smelting slag (LSS) on the compressive strength of cementitious materials. The results show that decreasing the particle size can significantly improve the compressive strength of the materials, especially in the early stage.
