Waste management has transformed over the past half a century, from key dumping and landfilling laws in the 1970s to today’s complex policies targeting plastic waste reduction and recycling. Still, global disparities are glaring, and stronger policies, infrastructure and technology are necessary to achieve a truly circular plastics economy.

Increasing environmental concerns demand the replacement of petroleum with renewable, sustainable resources to produce biodegradable and carbon-neutral products. As a natural, abundant and versatile biopolymer, cellulose has long been used in traditional applications such as paper and textiles and is now emerging in advanced fields including energy storage, healthcare, food, cosmetics, and paints and emulsions. Supramolecular chemistry offers a powerful strategy for engineering cellulose nanocomposites through specific, directional, tunable and reversible non-covalent interactions between nanocellulose and matrix components to achieve certain mechanical, chemical and biological properties. In this Review, we present the multiscale supramolecular engineering of cellulose nanocomposites and their fabrication and processing into materials. We provide a material and structural perspective of how the mechanical, ionic, optical and thermal properties and the environmental degradability of these nanocomposites can be regulated through supramolecular chemistry. Finally, we discuss how these approaches might address circularity and environmental sustainability goals, and we highlight major challenges and future prospects in the field, calling for further attention on supramolecular chemistry engineering to maximize the potential of these materials. Cellulose, a renewable and biodegradable biopolymer, is gaining momentum as a sustainable alternative to fossil-based materials. This Review explores how supramolecular chemistry enables the design, processing and function of cellulose nanocomposites for circular and high-performance applications.

Decoding the halogenation cost-performance paradox in organic solar cells 破解有机太阳能电池卤化成本-性能悖论
IF 86.2 1区 材料科学 Q1 MATERIALS SCIENCE, MULTIDISCIPLINARY Pub Date : 2025-05-21 DOI: 10.1038/s41578-025-00804-3

The power conversion efficiencies of organic solar cells have now surpassed 20%, marking a considerable advance in performance. This progress raises an important question: which molecular or macromolecular modifications contribute most effectively to efficiency gains? Among these, halogenation — specifically fluorination and chlorination — has been a key driver of performance improvements, making it a particularly promising avenue for materials exploration. In this Perspective, we provide a comparative discussion of a broad range of non-halogenated and halogenated building blocks, acceptors and donors, evaluating the impact of halogenation on efficiency and scalability. We also examine critical challenges, including organic solar cell durability, large-scale manufacturability and the realistic costs associated with halogenation, positioning it as a central factor in performance optimization. Organic solar cells that use halogenated building blocks now boast power conversion efficiencies beyond 20%, albeit at the expense of increased synthetic complexity. This Perspective explores trade-offs among efficiency, scalability and cost–effectiveness in halogenated organic solar cells.
有机太阳能电池的能量转换效率目前已超过20%,在性能上取得了相当大的进步。这一进展提出了一个重要的问题:哪种分子或大分子修饰最有效地提高了效率?其中,卤化-特别是氟化和氯化-一直是性能改进的关键驱动因素,使其成为材料探索的特别有前途的途径。在这一观点中,我们提供了广泛的非卤化和卤化构建块,受体和供体的比较讨论,评估卤化对效率和可扩展性的影响。我们还研究了关键挑战,包括有机太阳能电池的耐用性,大规模制造能力和与卤化相关的现实成本,将其定位为性能优化的核心因素。

Plasmonic lattice lasers 等离子体晶格激光器
IF 86.2 1区 材料科学 Q1 MATERIALS SCIENCE, MULTIDISCIPLINARY Pub Date : 2025-05-13 DOI: 10.1038/s41578-025-00803-4

Plasmonic lattice lasers offer a promising alternative to compact sources such as vertical-cavity surface-emitting lasers. These lasers have an open-cavity design consisting of periodic lattices of metallic nanoparticles that facilitate integration with both liquid-state and solid-state gain nanomaterials. Recent advances have enabled real-time control over lasing wavelength, tunable multimodal lasing, and design of complex polarization and intensity profiles. In this Review, we summarize key developments in plasmonic lattice lasers over the past 5 years, with a focus on unconventional lattice cavities and how they can facilitate tailored lasing characteristics. We discuss strategies for realizing multicolour and multidirectional emission, the advantages of different gain materials and the challenges of reducing lasing thresholds. Although substantial progress has been made, open questions regarding fabrication precision, threshold engineering and the realization of electrically driven plasmonic lasers remain. Plasmonic lattice lasers are poised to play a critical part in next-generation technologies for optical communication, sensing and quantum applications. Plasmonic nanoparticle lattices can function as optical cavities with unique properties for next-generation nanolasers. This Review describes how plasmonic lattice lasers can exhibit tailorable emission wavelength, polarization and directionality by judicious selection of gain nanomaterials, lattice symmetries and nanoparticle compositions.

Biomaterials in cellular agriculture and plant-based foods for the future 未来细胞农业和植物性食品中的生物材料
IF 86.2 1区 材料科学 Q1 MATERIALS SCIENCE, MULTIDISCIPLINARY Pub Date : 2025-05-07 DOI: 10.1038/s41578-025-00800-7

Alternative food products are needed to address the most pressing challenges faced by the food industry: growing global food demand, health concerns, animal welfare, food security and environmental sustainability. Future foods are defined as foods with scalability and sustainability potential owing to rapidly advancing technological developments in their production systems. Key areas of study for future foods include cellular agriculture and plant-based systems, which include biomaterials as key ingredients or as structural components to impart texture, support cell growth and metabolism, and provide nutrients and organoleptic factors to food products. This Review discusses current requirements, options and processing approaches for biomaterials with utility in future foods. We focus on two main approaches: cellular agriculture wherein the cells are the key component for food (with the biomaterials utilized to support the cells via adherence and/or for texture) and plant-based foods wherein acellular plant-derived biomaterials are the food components. In both cases, the same fundamental challenges apply for the biomaterials: achieving utility at scale and low cost while meeting food safety requirements. Other considerations for biomaterials for future foods are also addressed, including sustainability, modelling, consumer acceptance, nutrition, regulatory status and safety considerations to highlight the path ahead. This emerging field of biomaterials for future foods offers a new generation of biomaterial systems that can positively impact human health, environmental sustainability and animal welfare. Although scaling these biomaterial sources cost-effectively presents a major challenge, substantial progress is being made, and opportunities to establish supply chains are already underway. Biomaterials have a crucial role in the development of future foods, particularly in cellular agriculture and plant-based systems. This Review addresses the current status and future requirements of biomaterials for future foods, addressing key aspects such as structure, nutrition, safety, sensory attributes, sustainability and consumer preferences.
需要替代食品来解决食品工业面临的最紧迫挑战:不断增长的全球食品需求、健康问题、动物福利、粮食安全和环境可持续性。未来食品被定义为具有可扩展性和可持续性潜力的食品,因为其生产系统的技术发展迅速。未来食品的关键研究领域包括细胞农业和基于植物的系统,其中包括生物材料作为关键成分或结构成分来赋予质地,支持细胞生长和代谢,并为食品提供营养和感官因子。这篇综述讨论了生物材料在未来食品中应用的当前要求、选择和加工方法。我们专注于两种主要方法:细胞农业,其中细胞是食物的关键成分(利用生物材料通过粘附性和/或质地来支持细胞)和植物性食品,其中非细胞植物性生物材料是食物成分。在这两种情况下,同样的基本挑战适用于生物材料:实现大规模和低成本的效用,同时满足食品安全要求。未来食品中生物材料的其他考虑因素也得到了解决,包括可持续性、模型、消费者接受度、营养、监管状况和安全考虑,以突出未来的道路。这一用于未来食品的生物材料新兴领域提供了新一代生物材料系统,可以对人类健康、环境可持续性和动物福利产生积极影响。尽管经济有效地扩展这些生物材料来源是一项重大挑战,但正在取得实质性进展,并且已经有机会建立供应链。

Future foods are defined as foods with scalability and sustainability potential owing to rapidly advancing technological developments in their production systems. Key areas of study for future foods include cellular agriculture and plant-based systems, which include biomaterials as key ingredients or as structural components to impart texture, support cell growth and metabolism, and provide nutrients and organoleptic factors to food products. This Review discusses current requirements, options and processing approaches for biomaterials with utility in future foods. We focus on two main approaches: cellular agriculture wherein the cells are the key component for food (with the biomaterials utilized to support the cells via adherence and/or for texture) and plant-based foods wherein acellular plant-derived biomaterials are the food components. In both cases, the same fundamental challenges apply for the biomaterials: achieving utility at scale and low cost while meeting food safety requirements. Other considerations for biomaterials for future foods are also addressed, including sustainability, modelling, consumer acceptance, nutrition, regulatory status and safety considerations to highlight the path ahead.
