Summary: Noise and environmental problems have significant impacts on human beings through various stressors. To address these issues, environmentally friendly strategies are essential, particularly in materials manufacturing. This study presents a novel biomimetic and biophilic design of a lichen-Schwarz metamaterial (SLSM) that achieves multifunctional properties in noise attenuation and humidity control. The SLSM structure mimics a biomimetic shell and meta-symbiotic exoskeleton, providing sound attenuation and humidity control capabilities for future sustainable architecture.

Summary: A multifunctional water-based metamaterial with broadband x-to-y cross-polarization conversion and electromagnetic wave absorption functions is proposed. The metamaterial consists of a metallic dielectric substrate, a 3D printed container, and a metal backplane. The polarization conversion ratio exceeds 90% at 5.8-9.4 GHz when the container is filled with water, and excellent absorption performance is achieved at 16.1-16.9 GHz. Cross-polarization conversion is also achieved at 5.9-10.0 GHz and 14.3-16.4 GHz without water injection. Experimental validation demonstrates the unique properties of the proposed design, which holds significant potential for multifunctional and conformal stealth applications.

Summary: In this study, an absorption device based on one-step transfer of graphene was designed to determine the concentration of different antibiotics. It was found that the resonance position of the graphene-metamaterial absorber shifted to a higher frequency (blue shift) with increasing antibiotic concentration, suggesting that terahertz spectroscopy based on a metamaterial absorber could be used for the determination of macrocyclic antibiotic concentrations.

Summary: This study proposes a design method for kirigami art, which utilizes notch flexures to create 3D configuration patterns under uniaxial tension. The use of compliant beams as notches helps to distribute stress more uniformly. Experimental and numerical results show that the trigger condition of 3D patterns can be adjusted by tuning the geometric parameters and material properties.
