However, their applications are limited by challenge of simultaneously enhancing structural color and bioactive properties. Inspired by the coloration of blueberries, innovative, colorful, and multifunctional hydroxypropyl cellulose (HPC) photonic materials synergistically reinforced by natural deep eutectic solvents (NADES) and sodium copper chlorophyllin (SCC) were designed and characterized in terms of the color regulation mechanism, microstructure, color characteristics, mechanical properties, and antibacterial and antioxidant activities. The NADES differentially induced shifts in the structural color of HPC photonic gels through hydrogen-bonding and electrostatic interactions. Specifically, a blue shift was induced by choline- and acid-based NADES, as well as by NADES containing neither choline nor acids, whereas a red shift was caused only by acid-based NADES without choline. The NADES also differentially affected the responses to temperature, pressure, and tension deformation of the HPC photonic gels, with choline-containing NADES inhibiting their color response. Replacing conventional black absorbers with SCC produced spectral interplay between the characteristic absorption of SCC and the structural reflection of HPC, producing greenish tones and unique colors. The synergistic incorporation of representative NADES and SCC endowed the HPC photonic films with excellent antioxidant and antibacterial properties, while the NADES significantly enhanced the mechanical properties of the films, especially for films containing fructose- and citric acid-based NADES. These multifunctional HPC photonic materials with unique color retain multi-responsiveness and integrate antioxidant and antibacterial activities, color stability, and biodegradability, providing a highly promising platform for active and smart packaging or food coloring applications.</p>","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":"10082-10093"},"PeriodicalIF":11.4,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, highly filled ceramic adhesives are still commonly designed as bulk composites, with performance pursued by increasing filler loading or filler conductivity. This view overlooks how heat transport and adhesion are determined within the formed bondline, where filler connectivity, shear-dependent processability, wetting, and trapped air collectively govern performance. Here, we introduce a rheology-guided bondline densification strategy for multiscale thermally conductive adhesives composed of spherical Al₂O₃, plate-like hBN, fine AlN, and heat-activated polycaprolactone (PCL). The Al₂O₃/hBN architecture was optimized to balance shear-thinning flow, shape retention, and cured-state integrity, while fine AlN reinforced the conductive network. PCL was used as a thermoplastic densification mediator that softens during heat-primed mixing and suppresses microvoids within the ceramic-rich network. This strategy reduced microvoid formation, drove the skeletal density toward the composition-dependent theoretical density, and increased the surface free energy of the cured adhesive. The adhesive showed scale-bridging adaptability, conformally filling microscale roughness while remaining processable into large-area sheets and stamped macroscopic forms. The optimized adhesive achieved a through-plane thermal conductivity of 3.57 W m^-1 K^-1, representing a 2280% enhancement over neat epoxy and a 35% increase over the Al₂O₃/hBN baseline, along with a lap shear strength of 3.704 MPa, corresponding to a 113% improvement over the 20/40 baseline. Mobile-device heat-dissipation and load-bearing demonstrations further confirmed its practical applicability.

To address these gaps, we propose a programmable centimeter-scale multi-stable tensegrity metamaterial that removes complex prestressing and enhances energy absorption. In our architecture, arrays of bistable units are stacked to form multi-stable \"cables\" that replace the tensile members in a classic tensegrity structure, simultaneously self-prestressing the structure and dissipating energy through controlled state transitions. Programmability is achieved through a hierarchical design - from the bistable unit to the multi-stable cable and to the full tensegrity structure - guided by a pseudo-rigid-body model (PRBM) that predicts the mechanical responses. The multi-stable tensegrity metamaterials are prototyped using 3D printing techniques, and experiments show a 3.1× increase in energy absorption compared to a non-tensegrity counterpart, allowing fragile eggs to survive drops from 120 cm, comparable to the center-of-mass height of an adult during a typical fall.

This has emerged as a powerful concept to explain and enable emission in clustering-triggered emission (CTE) systems. In these contexts, strengthening intermolecular through-space interactions extends the effective conjugation length, thereby lowering the excited-state energy and promoting red-shifted emission. However, the prevailing paradigm has been exclusively to strengthen such interactions; the reverse strategy-deliberately disrupting them-remains entirely unexplored. Herein, we report a general molecular design strategy termed \"through-space conjugation decoupling (TSCD)\" to achieve robust blue-shifting fluorescent MFC materials. Guided by three synergistic design criteria, we synthesized a series of D-π-A fluorescent small molecules (Z2-Z6) that achieved efficient dual-state emission.

Systematic mechanistic studies combining X-ray diffraction, time-resolved photoluminescence and theoretical calculations confirm that the crystalline-to-amorphous transition disrupts the through-space conjugation, thereby widening the energy gap.

Here, by combining catalyst structure optimization and reaction interface regulation, we designed a liquid-liquid-solid three-phase system featuring an ultra-thin oil layer (L-L(UTO)-S) based on ordered TiO₂ porous films. The ordered porous films possess a large surface area and high surface roughness, facilitating the deposition of an ultra-thin oil layer on their surfaces.

Further studies on the influence of oil thickness in the L-L-S system indicated that the ultra-thin oil layer effectively minimizes the adverse impact on interfacial electron transfer arising from the insulating properties of oil.
