Science, Год журнала: 2024, Номер 385(6704), С. 68 - 74

Опубликована: Июль 4, 2024

Passive radiant cooling is a potentially sustainable thermal management strategy amid escalating global climate change. However, petrochemical-derived materials often face efficiency challenges owing to the absorption of sunlight. We present an intrinsic photoluminescent biomass aerogel, which has visible light reflectance exceeding 100%, that yields large effect. discovered DNA and gelatin aggregation into ordered layered aerogel achieves solar-weighted 104.0% in regions through fluorescence phosphorescence. The effect can reduce ambient temperatures by 16.0°C under high solar irradiance. In addition, efficiently produced at scale water-welding, displays reparability, recyclability, biodegradability, completing environmentally conscious life cycle. This photoluminescence material another tool for designing next-generation materials.

Abstract Recently, hydrogel‐based soft materials have demonstrated huge potential in robotics, flexible electronics as well artificial skins. Although various methods are developed to prepare tough and strong hydrogels, it is still challenging simultaneously enhance the strength toughness of especially for protein‐based hydrogels. Herein, a biomimetic “salting out—alignment—locking” tactic (SALT) introduced enhancing mechanical properties through synergy alignment salting out effect. As typical example, tensile modulus initially brittle gelatin hydrogels increase 940 folds 10.12 ± 0.50 MPa 2830 34.26 3.94 MPa, respectively, increases up 1785 14.28 3.13 MJ m −3 . The obtained hold records previously reported gelatin‐based hydrogel close tendons. It further elucidated that effect engenders hydrophobic domains, while prestretching facilitates chain alignment, both synergistically contributing outstanding properties. noteworthy SALT demonstrates remarkable versatility across different salt types polymer systems, thus opening new avenues engineering strong, tough, stiff

Living plastics from plasticizer-assisted thermal molding of silk protein

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Янв. 2, 2025

The pursuit of materials, particularly plastics, with a minimal ecological footprint throughout their circular lifecycle, is crucial for advancing sustainable materials development. Living composed embedded yet active organisms can leverage endogenous biotic resources to achieve functional that align sustainability goals. However, current living material systems face challenges such as weak mechanical properties, limited environmental adaptability, and restricted cellular functionality. In this study, we propose an approach by incorporating into silk-based plastics through plasticizer-assisted thermal molding process. We investigate the mechanism structure formation in these correlating manufacturing performance resulting secondary structure. These provide protective matrix probiotics, ensuring survival harsh gastrointestinal tract enhancing intestinal delivery. Similarly, soil rhizobacteria encapsulated within exhibit long-term protease activity, accelerating plastic degradation upon exposure. This work demonstrates potential form where are processed, entrapped, retain metabolic functions, protected environments. goals, but usually adaptability Here, authors report thermoplastic process develop silk protein-based dense structures, functioning matrices microorganisms.
