Materials and systems with tunable optical and spectroscopic properties have attracted much research interest for applications in adaptive camouflage technologies. Within this context, our laboratory has developed bioinspired surface wrinkling-based adaptive camouflage platforms with tunable visible-to-infrared properties. Herein, we build upon these efforts and report the scalable fabrication of squid skin-inspired ultraviolet-visible-near-infrared adaptive camouflage systems with improved response times and predictable spectroscopic functionalities. These findings lay the groundwork for the iterative computational design, high-throughput manufacturing, and performance optimization of analogous adaptive camouflage, heat management, light-to-heat conversion, rewritable optical, and electromagnetic shielding technologies.

Surface-enhanced Raman spectroscopy (SERS) has emerged as a powerful technique for the ultra-sensitive detection of molecules and has been widely applied in many fields, ranging from biomedical diagnostics and environmental monitoring to trace-level detection of chemical and biological analytes. While traditional metallic SERS substrates rely predominantly on electromagnetic field enhancement, emerging semiconductor SERS materials have attracted growing interest because they offer the additional advantage of simultaneous chemical and electromagnetic enhancements. Here, we review some of the recent advancements in the design and optimization of semiconductor SERS substrates, with a focus on their dual enhancement mechanisms. We also discuss the transition from nanoparticle-based platforms to more advanced nanoresonator-based SERS metasurfaces, highlighting their superior sensing performance.

Liquid crystal elastomers (LCEs) are promising materials for constructing and programming soft actuators and small-scale soft robotic systems due to their exceptional stimuli-responsive properties. However, fabricating complex-shaped LCE actuators with controlled shape transformations remains challenging. Herein, we present a welding-based strategy for fabricating light-responsive, multicomponent LCEs with complex shape morphing capabilities while preserving the distinct functional responses of individual components. This approach leverages dynamic disulfide bonds incorporated into surface-aligned, chain-extended LCEs, which enables robust adhesion between LCE segments without disrupting their molecular orientation during welding. The resulting structures seamlessly integrate differently oriented LCE segments, enabling diverse shape-morphing and establishing a platform for weldable, arbitrarily aligned, and complex-shaped LCE actuators.

Metal halide perovskites (MHPs) have been widely used as active (semiconducting) layers in electronic and optoelectronic devices for over two decades, owing to their tunable structural and electronic properties, which allow for meeting the requirements of diverse applications. However, the versatility of MHPs as gate dielectrics has been underexplored despite their substantially high dielectric constant, which is promising for low-power and soft electronics. In this perspective, we focus on understanding the dielectric polarizability of MHPs and their potential for use as gate dielectrics in thin-film transistor applications. We discuss recent studies on MHPs as gate dielectrics to provide new insights and highlight potential research opportunities for enhancing the performance of thin-film transistor devices by exploiting MHPs as gate dielectrics.

This study explores the synthesis protocol and examines the optical properties of dye-doped poly(methyl methacrylate) (PMMA) spheres, self-assembled into 3D colloidal photonic crystals. Utilizing a variety of luminescent dyes (POPOP, coumarin 6, DPP derivative, and DCM), emitting across the visible spectrum, this research proposes the incorporation of these dyes into PMMA spheres at the stage of the synthesis and use of the latter to produce luminescent 3D opals. The results of the study, which include comprehensive photoluminescence characterization, including quantum yield (QY) determination and angle-dependent emission analysis, provide a deep understanding of the integration process and the resulting photophysical properties. In addition, the effect of the dye addition on the size of the spheres and their monodispersity was evaluated. A careful choice of dyes and synthesis conditions in this study resulted in obtaining the materials that exhibit angle-dependent emission in different spectral ranges, demonstrating the versatility of the synthesis approach. Adjusting the sphere size to match specific dye emission wavelengths enabled the effective alignment of photonic band gap positions with the emission spectra, resulting in emission color shifts with the viewing angle. These findings significantly contribute to the advancement of the design of functional materials with tailored optical properties. Moreover, the results highlight the potential of these materials for advanced optical applications, particularly in anti-counterfeiting material technologies, and provide a versatile approach to designing materials with tunable optical properties.

A precise detection of palladium (Pd) ions is a critical challenge with significant socio-economic implications across various industrial and chemical sectors. Due to its widespread use and poor biodegradability, Pd²⁺ accumulates in environmental ecosystems, posing severe risks to both the environment and living organisms. Consequently, there is a strong demand for selective, sensitive, and user-friendly detection methods. Among emerging strategies, optical detection techniques (both luminescence and colorimetric) using metal-based receptors have gained considerable attention. These sensors offer distinct advantages over traditional organic probes, including large Stokes shifts, long emission lifetimes, exceptional photostability, enhanced water solubility, recyclability, and remarkable chemical versatility. These attributes make them highly suitable for diverse applications in sensing and bioanalytical fields. This review provides a comprehensive overview of recent advancements in luminescent and colorimetric metal-based probes, including metal complexes and metal–organic frameworks (MOFs), for the selective detection of Pd²⁺. It discusses key design strategies, critical performance factors, and future prospects, offering valuable insights for researchers working on the next-generation sensing platform.

The rapid development of wireless communication technology has caused serious electromagnetic damage and electromagnetic pollution while bringing great convenience to the society and the people at the military and civilian levels. Electromagnetic wave (EMW)-absorbing materials, such as three-dimensional porous carbon-based materials, are considered ideal for solving electromagnetic pollution owing to their low density, light weight, excellent electrical conductivity, high chemical stability, and strong absorption properties.

Using the principle of EMW absorption, the basic theory of EMW absorption and loss mechanisms are introduced. Then, the preparation strategies for different structures of the selected materials are discussed in detail. Next, the structure-component synergies and multifunctionality of 3D porous carbon-based materials are highlighted. Finally, an outlook on the future study direction of 3D porous carbon-based materials is provided, and the challenges as well as the possible solution strategies are highlighted. This review aims to provide researchers with a comprehensive understanding of 3D porous carbon-based materials with regard to their preparation strategy, structure-component synergy, and multifunctional levels to facilitate their further innovation.
