Summary: Metamaterials, a type of engineered material, have gained more attention from researchers. Traditional metamaterial absorbers have a sandwich structure with metal layers, which increases the complexity and cost. To overcome these problems, an absorber based on all-dielectric metamaterial is proposed, using 3D printed materials. The 3D printed absorber shows lightweight, small volume, and easy fabrication, with resonance absorption peaks reaching -35 dB.

Summary: This study presents a dual-layer HfO2 grating for full-color modulation in the visible spectrum. The lower-layer HfO2 grating induces magnetic dipole resonance, while the upper-layer HfO2 grating suppresses high-order Mie resonances. Compared to a single-layer HfO2 grating, the HfO2/HfO2 grating exhibits larger distribution area in the CIE 1931 chromaticity diagram and closer structural color saturation to monochromatic light. The structure shows promising potential in imaging and display applications.

Summary: This study demonstrates the sensing capabilities of a chip-based metamaterial, combining 3D chiral geometry with a functional core-shell nanoarchitecture. The modified optical response of the chiral metamaterial allows for analysis in complex environments and efficient interaction with biomolecules, leading to high sensitivity detection of biomarkers. Measurements in spiked solution and human serum show the potential for early diagnostics and diseases progression monitoring in a range not accessible with common immunological assays, opening new perspectives for next-generation biomedical systems.

Summary: In this study, a dual-band low-permittivity all-dielectric metamaterial absorber (ADMMAs) was designed and fabricated using 3D printing. The simulation and experimental results showed that 3D printing is a better alternative for the fabrication of low-permittivity ADMMAs, and the absorption peaks of the absorber are highly sensitive to the surrounding environment.

Summary: In this study, the spatially resolved dielectric functions of Si@MoS2 with nanoscale spatial resolution were extracted using valence electron energy loss spectroscopy (VEELS) and verified through simulations. The contribution of the Si/MoS2 interface was further explored using a cross-sectioned core-shell structure.

Summary: Heterostructures of transition metal dichalcogenides and optical cavities have great potential in quantum optics and electronics. In this study, Si@MoS2 core-shells were synthesized and MD mode splitting was experimentally demonstrated, showing evidence for resonance coupling. Additionally, higher-order systems with tunable properties were demonstrated through a dimer system of Si@MoS2.

Summary: We report a novel and facile strategy to achieve monodispersed polymer-based circularly polarized luminescent (CPL) micro/nanomaterials. The core/shell particles obtained using maleic anhydride copolymer as core and chiral helical polyacetylene as shell exhibit intense blue-emitting nonconventional fluorescence with both aggregation-induced emission and concentration-enhanced emission performance. Furthermore, these particles show excitation-dependent CPL emission behavior, with the highest luminescence dissymmetry factor of 5 x 10-3. This work provides a versatile platform for constructing polymeric CPL nano/microarchitectures.

Summary: A synthetic toolbox has been developed to create monodisperse core-shell and core-shell-shell particles composed entirely of different types of conjugated polymers. Seeded and fed-batch dispersion polymerizations based on Suzuki-Miyaura-type cross-coupling allow precise control over the interface between conjugated polymer phases, facilitating control over energy transfer phenomena. This new approach offers synthetic freedom for fine-tuning the optical properties of CPP, potentially enabling the synthesis of individual white light-emitting particles.

Summary: A new type of hybrid core-shell nanoparticle dielectric suitable for inkjet printing is introduced, with gold cores covalently grafted with polystyrene to create dielectric layers with metal volume fractions of 5 to 21%. The materials show high dielectric constants without the risk of breakdown at high metal fractions, making them ideal for capacitor applications.

Summary: The study analytically investigated the interaction between a certain type of core-shell nanoparticle and a hyperbolic metamaterial (HMM) shell made of alternating layers of silicon dioxide and indium-tin-oxide (ITO). The effects of parametric features such as fill-factor and core-shell radii on constitutive properties, polarizability, and scattering and absorption cross-sections were discussed in detail. Results showed that the constitutive features of the shell, including dielectric and HMM properties, could be altered depending on the ITO fill-factor and operating wavelength.
