Summary: This article proposes a simple method for preparing multifunctional NiCo/C aerogels with excellent electromagnetic wave absorption properties, superhydrophobicity, and self-cleaning by water-induced NiCo-MOF self-assembly. The impedance matching of the 3D structure and the interfacial polarization provided by CoNi/C, as well as the defect-induced dipole polarization, are the primary contributors to the broadband absorption. As a result, the prepared NiCo/C aerogels have a broadband width of 6.22 GHz at 1.9 mm. Due to the presence of hydrophobic functional groups, CoNi/C aerogels improve stability in humid environments and obtain hydrophobicity with large contact angles > 140 degrees. This multifunctional aerogel has promising applications in electromagnetic wave absorption and resistance to water or humid environments.

Summary: Utilizing cellulose nanofibers (CNFs) as an assistant, the ambient-pressure-dried (APD) preparation of MXene-based aerogels with ultralight but robust, highly conductive, and large-area properties is achievable. The strong interactions between CNF and MXene, as well as the biomimetic microstructure, contribute to the high mechanical strength and stability of the aerogels. Moreover, the abundant functional groups of CNFs enhance the chemical crosslinking and improve the hydrophobicity, water resistance, and oxidation stability of the MXene-based aerogels. The ultrathin, 1D nature of CNFs leads to minimal interlayered gaps and numerous heterogeneous interfaces in the MXenes, resulting in excellent conductivity and electromagnetic interference shielding performance of the aerogels.

Summary: This paper discusses the power coupling problem of the traditional virtual synchronous generator (VSG) control strategy in medium and low-voltage microgrids, analyzes the cause of power coupling, and discusses the necessity for decoupling. In addition, a power decoupling control strategy based on an adaptive diagonal matrix compensation matrix is proposed, which compensates for the coupling component and fully decouples the output power of the VSG. The proposed strategy also tracks variations in the static operating point of the VSG and automatically adjusts the compensation component to handle frequent load switching on the grid side of a microgrid. Simultaneously, the stability of the VSG is analyzed using the transient instability criterion of the power system to ensure decoupling, and the effectiveness of the proposed control strategy is verified by simulation and experimental results.

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.
