Summary: This study proposes an optical rotation-based color tuning method, which provides a wide range of color tunability using a controlled cholesteric liquid crystal and two polarizers. The color range can be manipulated by engineering the optical rotation of the liquid crystal film, resulting in the attenuation of unexpected light sources and improved visibility.

Summary: A novel photonics-based multivariate pattern recognition technique is used to segregate bison meat samples based on color attributes obtained from visible to near-infrared hyperspectral images. The wavelength region from 500 to 690 nm plays a significant role in classification, with Partial Least Squares Discriminant Analysis demonstrating high accuracy.

Summary: Photonic Janus particles with a sphere fused to a cone are created through the phase separation of dendronized brush block copolymers and poly(4-vinylpyridine)-r-polystyrene. The particles exhibit tunable structural colors by varying the molecular weight of the copolymers and can be surface-modified for multifunctionality. A real-time magnetic control and electrostatic immobilization of charged biomolecules are achieved, enabling potential applications in biosensing. A new photonic sensor for detecting Salmonella is developed using antibody-modified photonic Janus particles, with the angle-dependent structural color playing a key role in the sensing mechanism.

Summary: In this study, we developed inverse opal photonic crystals (IOPCs) that can function as real-time identifiable labels by adjusting the structure color and chemical color under UV and NIR light. The IOPCs were prepared by etching a silica photonic crystal template in a thermosensitive hydrogel containing NP. The combination of the green structure color of IOPCs and the red chemical color of the hydrogel resulted in the appearance of yellow color. The structure color of IOPCs changed from green to blue under NIR light, and when simultaneously irradiated by UV and NIR light, the IOPCs appeared purple due to the superimposition of the blue structure color and red chemical color.

Summary: In this study, visible and infrared dual-band anti-counterfeiting is achieved for the first time using metamaterial-photonic crystal heterostructures. TiO2 nanoparticles and polystyrene microspheres self-assemble to form a van der Waals interface, connecting the TiO2 metamaterial to the polystyrene photonic crystal. The difference in characteristic length scales between the two components allows for photonic bandgap engineering in the visible band and creates a solid interface to prevent interference in the mid-infrared. The hidden TiO2 metamaterial is visualized using refractive index matching liquid or thermal imaging. The compatibility of optical modes and ease of interface treatments pave the way for multifunctional photonic heterostructures.

Summary: Refractory metal-oxide semiconductors, with their high melting points and tunable optical constants, are a neglected platform for nanophononics. We demonstrate that these semiconductors can form metacoatings made of highly subwavelength, periodic metal-oxide layers with a varying refractive index profile. These metacoatings exhibit vibrant structural colors and can be tuned across the visible spectrum through thermal annealing techniques.

Summary: Structural color can be produced by nanoperiodic dielectric structures using soft materials, and stretchable chiral photonic elastomers (CPEs) can self-organize into a helical nanostructure, with the chiral nanostructural color controlled by stretching. This study presents stretchable CPEs with simultaneous multicolor control, including electrical control, and demonstrates various device applications such as multiarrayed color binning and chameleon-like photonic e-skin. The ability to control the separation of biomimetic multicolors in stretchable photonic systems improves the functionality of potential photonic applications.

Summary: Passive daytime radiative cooling (PDRC) is gaining attention for its ability to cool without electricity. Porous polymers are attractive due to their excellent performance and scalability. This study explores how PDRC performance is affected by pore properties, such as size and porosity, through optical simulations. The results show that mixed nanopores have higher solar reflectance than single-sized pores, and under a semi-humid atmospheric condition, using an AI substrate can significantly increase thermal emittance and net cooling power. These findings provide guidance for designing high-performance porous coatings for PDRC applications.

Summary: A facile method for building responsive photonic crystal patterns was developed, utilizing commercially printed patterns as masks to induce invisible patterns through wetting. The masked areas exhibit strong structural colors while the unmasked areas remain transparent, providing a unique and reversible wetting feature. This programmable printing technique is expected to be an environmentally friendly approach for scalable invisible optical anti-counterfeiting technology.
