Summary: In this study, the dynamic variation of xylem development in Fraxinus mandshurica (M8) and a novel interspecific hybrid F. mandshurica x Fraxinus sogdiana (1601) was evaluated. The results showed that the xylem development cycle of 1601 was extended compared to that of M8, with increased cellulose content and reduced lignin content observed in 1601. The vessel length and width were also significantly increased in 1601. Furthermore, the study identified differentially expressed genes and hub genes related to cellulose synthesis, lignin biosynthesis, and brassinosteroid (BR) signaling, indicating the critical role of BR biosynthesis and signaling in wood development and properties.

Summary: Constructing a controllable electromagnetic gradient is important for advanced electromagnetic interference shielding composites. A sandwich-structured Cu-Ni wood composite (CNWC) with excellent electromagnetic shielding effectiveness (average value 57.4 dB) was successfully fabricated. The wood-based composite exhibited maximum saturation magnetization of 7.7 emu/g and increased conductivity to 1930 S/cm. The electromagnetic gradient sandwich-structure enabled multi-dielectric interface loss and multiple reflection loss, combining dielectric loss and magnetic loss to improve electromagnetic wave attenuation.

Summary: The electroless plating and electrodeposition process was used to prepare a Ni-Cu-P bilayer composite film with hydrophobic properties on the Ni-P film. The introduction of Cu inhibits the growth of cellular structures, increases nucleation points, and improves the microstructure of the Ni-Cu-P films. The Ni-P/Ni-Cu-P bilayer composite film has a pinecone-like convex structure, reduces surface energy, exhibits hydrophobicity, and effectively resists external impurities and fouling, improving corrosion resistance.

Summary: In this study, a lightweight, ultra-thin, and efficient Ni/Wood/Ni composite (NWNC) for electromagnetic interference shielding was constructed using a layer-by-layer assembly strategy and a simple electroless plating method. The synthesized NWNC exhibited a smooth surface and low surface roughness, demonstrating good conductivity and high electromagnetic shielding effectiveness. Furthermore, the electromagnetic network formed by the nickel layer in the composite material, combined with the porous structure of the wood, resulted in an electromagnetic shielding mechanism dominated by absorption.

Summary: With the rapid development of electronic technique, enormous electromagnetic pollutions have emerged, and high-performance electromagnetic interference shielding composites are greatly desired. In this study, a lightweight, porous carbon fiber felt/Ag/polydimethylsiloxane (CFF/Ag/PDMS) composite film was fabricated. The film exhibited excellent electrical conductivity and superior EMI shielding effectiveness (EMI SE) due to the homogeneously distributed Ag nanoparticles and the porous structure of CFF. The composite film also showed outstanding corrosion resistance, oxidation resistance, electro/photo-thermal conversion effect, and heating controllability, making it highly promising for applications in 5G communication technology and thermal management.

Summary: This study focuses on the preparation of absorption-dominant electromagnetic shielding materials using silver (Ag) micro-tubes with superstructure fabricated via deposition of Ag nanoparticles on poly(lactic acid) (PLA) fibers. The composites show ultrahigh electromagnetic interference (EMI) shielding effectiveness and low density, attributed to the absorption dominant shielding mechanism of the Ag micro-tubes. The superstructure of the Ag micro-tubes creates efficient surface plasmon resonance, electronic vibration, interfacial polarization, capacitance effect, and conductive loss, contributing to the high absorption and low density of the materials.
