The optimization of impedance matching by the absorbing structure can significantly broaden the absorption bandwidth. However, the high dielectric properties of SiC_f/Si₃N₄ composites at high temperatures resulted in the attenuation of absorption performance. Herein, the strategy of regulating the high-temperature dielectric properties of SiC_f/Si₃N₄ was proposed to enhance the high-temperature absorption performance of corrugated structure SiC_f/Si₃N₄. The effective absorption bandwidth of corrugated structure SiC_f/Si₃N₄ reaches 7.6 GHz at 1000 °C, which means that it is a new method for improving the absorption performance at high temperatures.

Sub-1 nm materials (SNMs) feature large specific surface areas and near 100% atomic exposures, thus offering abundant exposed active sites and properties well suited for applications in optics, electricity, catalysis, etc. In particular, polyoxometalate (POM)-based SNMs hold great promise for energy storage/conversion applications because of their nanoscale dimensions and synergetic effect of multiple components. Despite the abundance of reported POM-based SNMs, systematic reviews of their synthesis and energy storage/conversion applications are scarce. This review summarizes progress in the synthesis of POM-based SNMs and their applications in energy storage (e.g., Li-ion, Na-ion, Li-O₂, Zn-O₂, and Li-S batteries) and conversion (e.g., photothermal conversion, solar steam generation, and seawater desalination). Moreover, we discuss the related challenges and future perspectives, providing new insights into the rational design and development of efficient POM-based SNMs suitable for energy storage and conversion.

The performance of vat photopolymerization (VPP) additive manufactured ceramics is critically limited by weak interlayer bonding, which represents a challenge inherent to the layer-by-layer process. This study introduces a novel paradigm by conceptualizing the interlayer as a dynamic system evolving under photo-thermal fields. By precisely controlling UV energy input, a controlled incompletely polymerized state is introduced to enhance interlayer bonding via the effective dynamic balance of primary and secondary photopolymerization. Subsequent sintering is tailored to improve particle packing density at the interlayer. This work establishes a framework that connects process parameters to interlayer evolution and properties, offering both a practical pathway and a novel theoretical perspective for the manufacturing of high-performance ceramics.

By exploiting the oxygen/sulfur selectivity of V in a POM precursor, a strongly coupled V₂O₅/MoS₂ heterojunction was directly constructed on CC via one-step hydrothermal synthesis, exhibiting excellent HER performance and stability.

A recent review in Polyoxometalates summarizes the latest advances in the design, synthesis, and application of one-dimensional subnanometer materials constructed from polyoxometalate clusters. These subnanomaterials exhibit unique electronic and catalytic properties, with promising potential in redox catalysis, CO₂ reduction, photothermal conversion, and flexible device integration.
