Low-dimensional perovskite structures are widely explored for surface passivation due to their effective suppression of interfacial defects and enhanced environmental stability. While terminal molecules for constructing low-dimensional structures provide excellent passivation, they can introduce potential barriers for charge transport if the energy levels are not well-aligned. Herein, a tryptamine molecule is explored as the terminal molecule for the construction of a low-dimensional structure for passivating the buried interface of perovskite solar cells. Based on the inclusion of nitrogen atoms in the aromatic heterocyclic structure, the terminal molecule shows an uplifted HOMO level that aligns well with the perovskite skeleton, giving rise to enhanced orbit coupling. Therefore, this low-dimensional structure enables excellent surface passivation and interfacial carrier transport simultaneously, generating an outstanding open-circuit voltage (VOC) up to 1.266 V and an efficiency of 23.53% for single-junction wide-bandgap (1.68 eV) perovskite solar cells. This improvement enables the fabrication of the perovskite/silicon tandem solar cell with an efficiency of 33.22% (32.88% assessed by a third party) and a VOC of 1.987 V. Moreover, the fast carrier transport at the interface suppressed the halide phase segregation, bringing much enhanced operation stability.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e23069"},"PeriodicalIF":26.8,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831198","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}

While salt-based composites are widely employed as SAWH sorbents, they are often constrained by limited water yield from low sorption capacity and slow sorption/desorption kinetics due to diffusion barriers. Here, a new strategy is proposed to enhance moisture transport and storage space by fabricating oriented interconnected macroporous polymer gels via salt-templated crystallization-induced confined polymerization. Benefiting from this optimized interconnected hierarchical structure and the synergistic effect between PAMPS and LiCl, the salt-templated crystallization gel (STC/TiN-gel@LiCl) exhibits a record-breaking moisture uptake of 7.19 g g- 1, ultrafast sorption kinetics of 1.96 g g- 1 h- 1, and rapid desorption rate of 96.8% per hour under 1.0 sun illumination. After 20 cycles under high-humidity conditions (25°C, 90% RH), the gel retains over 90.4% of its initial water uptake capacity without leakage, confirming its long-term durability. Moreover, it delivers an outstanding water production rate of 3.29 kg kg- 1 day- 1 even under low-temperature and moderate humidity conditions (14.5°C, 55.6% RH).

As deployment scales, closed-loop recycling of perovskite PV will be beneficial to conserve critical resources and mitigate environmental risks associated with lead. However, mixed-cation, mixed-halide perovskites-typical in record-efficiency devices-undergo systematic composition drift during device fabrication. Consequently, material recovered from end-of-life modules inherits these deviations, degrading cell performance if reused without adjustment. To overcome this fundamental bottleneck in circular manufacturing, we developed a comprehensive quantification framework to audit and restore perovskite composition. By combining nuclear magnetic resonance (NMR), inductively coupled plasma-optical emission spectroscopy (ICP-OES), and ion chromatography (IC), we obtained full compositional fingerprints of the hybrid perovskite recovered from processed solar-cell stacks, allowing us to resolve their altered composition and restore the material to match the original precursor formulation. Composition restoration effectively closed the performance gap, yielding recycled perovskite cells with efficiencies comparable to pristine devices. A cost analysis demonstrates this approach can achieve a 69.1% cost reduction, while preserving supply-constrained elements like Cs and I. These results demonstrate a practical, compositionally informed pathway for the sustainable, closed-loop manufacturing of complex perovskite absorbers.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73266"},"PeriodicalIF":26.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831228","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}

Slow-relaxing, elastic networks restrict actomyosin-driven remodeling, limiting DC motility and reducing DC-T cell encounters and activation. Blocking DC migration in fast-relaxing matrices recapitulated key aspects of the impaired T cell priming seen in elastic networks, identifying migration as a mechanical checkpoint for immune activation. Prolonged confinement in elastic matrices induced a mechanomemory state, locking DCs into a state of reduced motility and altered chromatin accessibility. Studies using patient-derived ependymoma samples confirmed these findings, establishing viscoelastic relaxation as a key physical regulator of immune priming. Together, this tunable viscoelastic platform provides a defined, human-relevant model to dissect and model mechanical control of immunity for therapeutic design.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e23274"},"PeriodicalIF":26.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831095","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, the effect of catalyst structural engineering on the liquid phase is equally crucial and has long been insufficiently emphasized. Interfacial water with unique structural configurations and dynamic properties has been shown to regulate critical steps in electrocatalytic reaction. Therefore, we are motivated to write this review, in order to systematically overview the research progress and key challenges in this area. This review first introduces the fundamental properties for interfacial water, including structural types and molecular orientation. Subsequently, a series of advanced experimental characterization techniques and computational methods are provided to detect interfacial water, which is crucial for obtaining accurate structural information.

As a systems-level alternative, multifunctional bio-based packaging integrates two or more functions within and/or across preservation and quality monitoring, evolving from passive barriers into structure-informed platforms that couple material chemistry, hierarchical architecture, and transport regulation. This review summarizes advances from 2020-2025 across radiative cooling systems, modified atmosphere packaging, active platforms, intelligent sensing labels, and superhydrophobic surfaces. We synthesize design principles through a structure-transport-function lens and emphasize commodity-specific operating windows linking physiology to permeability/selectivity, release kinetics, and sensing reliability. To enable cross-study comparison, we define integration paradigms (superposition, coupling, and quantitatively validated synergy) and adopt standardized benchmarking based on the shelf life multiplier. Translation readiness is assessed via scalable manufacturing, migration and biosafety, ISO-aligned LCA, TEA, and consumer acceptance.

While cluster-related challenges have been partially explored in perovskite photovoltaics, systematic investigations into their mechanisms and practical solutions for perovskite light-emitting diodes (PeLEDs) remain scarce. Herein, we introduce a cluster-free intrinsic assembly strategy to fundamentally reshape the crystallization dynamics of perovskites. By exploiting the diuretic furosemide (FRSM) as an ionic binder, we achieve simultaneous coordination of all ionic components within the perovskite precursor, effectively suppressing cluster formation and redirecting crystallization toward a cluster-free intrinsic assembly pathway. The resulting perovskite films exhibit homogeneous high-quality perovskite nanocrystal structure, with exceptional optoelectronic properties and remarkable ambient stability. These advancements enable PeLEDs with a record external quantum efficiency (EQE) of 31.0% alongside unprecedented operational stability (equivalent T50 >310 000 h at 100 cd m-2, T90 > 1000 h at 1000 cd m-2), establishing new performance benchmarks for PeLEDs.
