Although internal quantum efficiency (IQE) has reached unity, the external quantum efficiency (EQE) of LEDs utilizing spherical quantum dots (QDs) is limited by low light outcoupling efficiency (η<sub>out</sub>). A promising approach to improve η<sub>out</sub> is using horizontal alignment of nanocrystals' transition dipole moments, such as aligned quantum rods (QRs), which provide directional light emission. Though the IQE for QRs has recently improved significantly, creating efficient and bright green-emitting QRs (515-560 nm) remains a big challenge, which is essential for full-color display applications. In this study, a uniform and highly bright green-emitting CdSe/Zn<sub>x</sub>Cd<sub>1-x</sub>S QRs of gradient shell structure are synthesized with minimized shell thickness and reduced Zn content, coupled with shorter organic ligands to reduce the energy barriers and enhance carriers injection. The electron leakage current at the interface between the polymeric hole transport layer (HTL) and QRs is the primary factor limiting the QRLED's performance. HTL with a higher energy offset is employed to prevent electron leakage at the organic/inorganic interface. Furthermore, is developed a bilayer HTL that enhances hole injections while minimizing electron leakage, thereby improving charge balance. The resulting QRLEDs demonstrate a record-high efficiency, with an EQE of 24%, current efficiency (CE) of 89 cd A<sup>-1</sup>, and maximum brightness (L<sub>max</sub>) exceeding 500k cd m<sup>-</sup> <sup>2</sup>.

Although thrombin is a widely used hemostatic agent, its efficacy is limited in the harsh environment of the digestive tract, especially in patients with chronic liver disease or coagulation disorders. Current treatment techniques often fall short, particularly when faced with severe blood loss and coagulation challenges. Here, a novel solution: waxberry-inspired smart nanogels that offer a cost-effective, highly efficient, and mechanically stable approach for local hemostasis is presented. Drawing inspiration from the microfibrous structures of waxberry, a waxberry-like nano-silica with a radially fibrous structure is synthesized for effective thrombin loading and release upon emergency. This nano-silica, coated with GelMA, forms a stable nanogel network activated by blue laser during endoscopy. Within just 5 s, the nanogel effectively triggers coagulation, even in patients with coagulation disorders. The formed blood clots are stable enough to withstand the challenging conditions of the digestive tract, preventing secondary bleeding. Upon injection, thrombin rapidly converts fibrinogen to fibrin, creating a secondary network that reinforces clot stability. This dual-network system demonstrates strong adhesive properties and effective hemostasis in the blood of cirrhotic patients, as well as in gastrointestinal bleeding scenarios involving the esophagus, stomach, and duodenum of mini-pigs.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"62 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving high-performance organic RTP remains challenging due to weak spin-orbit coupling, rapid non-radiative decay, and unstable triplet excitons. Early studies focused on crystal engineering, as ordered lattices restrict molecular motion and stabilize triplet excitons. Analyzing crystal structures and packing provides valuable insights into intermolecular interactions, while theoretical calculations have clarified electronic structures, laying the foundation for rational RTP material design. However, recent findings suggest RTP in many single-component systems may arise from trace impurities, significantly influencing RTP properties. This discovery has greatly advanced the understanding of impurity-induced phosphorescence. This review systematically examines the role of impurities in RTP, detailing their origins from starting materials, solvents, and side reactions. It also explores how these identified impurities can serve as essential building blocks for designing new RTP materials. Finally, essential methods for evaluating compound purity, emphasizing the critical importance of rigorous analysis and validation are presented. Material purity plays a pivotal role in RTP research, as impurities can distort experimental data, potentially leading to misinterpretations that can impede advancements in understanding the underlying mechanisms.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"11 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing mechanical and chemical recycling strategies struggle to sustainably and efficiently reuse PBT, resulting in product performance degradation and making the recycling process more costly than the upstream synthesis routes for raw materials. Inspired by DNA editing technologies in molecular biology, a modular molecular editing strategy is proposed to sequentially modify the backbone and end groups of end-of-life PBT, transforming it into a high-performance, sustainable, and 3D-printable poly(butylene adipate-<i>co</i>-terephthalate) (PBAT) platform. Unlike traditional commercial PBATs that produce only single components, this platform surpasses them in tensile strength and toughness without requiring additional additives and features programmable properties for diverse applications, including injection-molded parts, 3D-printed components, films, packaging, fibers, and fabrics. The industrial scalability of this strategy is validated through successful 100-L pilot-scale production. The resulting PBAT allows closed-loop polymer-to-polymer recycling by reintroducing PBT or monomers, thereby enhancing its social sustainability. When recovery is no longer feasible, the materials remain ecologically sustainable through composting, avoiding harmful environmental accumulation. This work achieves a direct polymer-to-polymer conversion of end-of-life PBT into high-performance materials, with techno-economic analysis highlighting both environmental and economic advantages.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"15 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
