Summary: This study reports vertically stacked luminescent heterojunction micropixels, which are capable of constructing high-resolution, multiplexed anticounterfeiting labels. By modulating the lengths of the subpixels, full-scale color synthesis for individual pixels is achieved. This design not only improves pixel density and security level, but also provides a versatile manufacturing platform for 3D display devices.

Summary: Researchers have developed an active structural color technology for display applications. By electrochemically depositing and dissolving copper on a platinum electrode, they were able to achieve reversible color switching and control. The modulation of copper occupancy in the slits allowed for changes in color interference, highlighting the potential of this technology for reflective display applications.

Summary: Electrochemical techniques have been increasingly used for heavy metal remediation and sustainable recycling. Biomimetic neuron-like adsorptive networks have been constructed, showing good adsorption capacity for cations and oxyanions. These networks can be switched for desorption at the oxidized and reduced states, facilitating electron transfer and redox reactions. The combination of simulations and calculations demonstrates enhanced desorption efficiencies due to curvature-induced polarization in hollow MOF structures, showing promise for water economy and downstream waste sustainability.

Summary: The preparation and characterization of two fluorescence dyes, T-2-BT and T-3-BT, are demonstrated to be responsive to various external stimulations such as solvent, acid, base and electrical potentials. The dyes exhibit excited state intramolecular proton transfer (ESIPT) phenomenon in organic solvents without oxygen atoms and display multi-colored emission in different charge states, enabling the development of a white emission system and multi-colored electrofluorochromic cells.

Summary: Tunable full-color luminescence is achieved by mixing rare-earth-doped SrAl2O4: Eu2+, Dy3+ (green emission), Y2O2S: Eu3+, Mg2+, Ti4+, Ti4+ 0.05 (red emission), and Sr2MgSi2O7: Eu2+, Dy3+ (blue emission) phosphors with different ratios. The phosphors exhibit white light and full-spectra emission under low excitation energy. The strategy enables enhanced encryption capacity of luminescent unit-based 3D codes with infinite emission colors.

Summary: Medical interventional catheters are essential devices that are revolutionizing clinical applications in various specialties. However, challenges still exist in terms of antibiofilm properties and effective drug delivery. Inspired by nature, a bioinspired superwettable catheter has been developed using inverse opal photonic crystals hydrogel. This catheter features a slippery liquid-infused porous surface (SLIPS) that changes the motion state of droplets. The catheter's tunable structural color and drug release properties, achieved through the expansion and contraction of the hydrogel, allow it to report and quantitatively feedback on the drug release process. With excellent antibacterial performance and drug release monitoring capabilities, this multifunctional superwettable catheter holds great promise in biomedical applications.

Summary: This study presents a strategy for developing block copolymer photonic crystal inks with tunable structures by blending two lamellar-forming BCPs. The control of the blending ratio enables the modulation of the periodicity and structure of the photonic crystal thin film, resulting in full-visible-range structural color. The transparent PC inks are used to create full-color structural color paintings, allowing for low-power pattern encryption.

Summary: In this study, video-rate color three-dimensional (3D) volumetric displays were demonstrated using elemental-migration-assisted full-color-tunable upconversion nanoparticles (UCNPs). By adjusting the intermediate shell thickness between the core and the sensitizer-doped second shell, red-green orthogonal upconversion luminescence (UCL) was achieved. Highly efficient red-green-blue orthogonal UCL and full-color tunability were achieved in the UCNPs through a combination of elemental-migration-assisted color tuning and selective photon blocking. 3D volumetric displays were fabricated using a UCNP-polydimethylsiloxane composite, allowing for the creation of 3D color images and motion pictures.
