However, this technique faces substantial challenges, primarily due to ice-related damage and biological stress responses. This review first highlights these critical obstacles and then examines the sophisticated strategies that various organisms have evolved to survive extreme cold. Key mechanisms include complex biological stress responses (involving cold signal perception, metabolic reconfiguration) and physical ice-control strategies, such as deep eutectic solvents (DESs), adsorption-inhibition by ice-binding proteins (IBPs), and the crowding assemblies such as coacervates and hydrogels. Inspired by these biological principles, the review discusses significant advances in cryoprotection technology: 1) Innovative cold-adaptation biology applied to organ preservation; 2) Advanced techniques to develop artificial ice-controlling molecules and materials; 3) Advanced rewarming strategies utilizing nanoparticles. Despite this promising progress, key challenges in translating these laboratory innovations into clinical practice are discussed. Finally, we propose an ideal \"cocktail-style\" cryoprotectant combining vascular-targeted nanoparticles for ice control, extracellular matrix-stabilizing polymers, cell-specific ice regulators, and metabolic modulators, potentially transforming transplant medicine through global organ banking and advancing regenerative therapies.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"15 1","pages":"e10982"},"PeriodicalIF":29.4,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140081","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}

Although a hybrid deposition method has been developed to achieve conformal and scalable growth of perovskite film on textured silicon, this dry/wet approach faces problems of incomplete reaction and phase impurities, posing a challenge for up-scaling fabrication. Herein, a synergistic strategy is demonstrated for homogeneity regulation of penetration of organic salts by employing solvent engineering in slot-die coating combined with near-infrared (NIR) irradiation pre-heating. The use of mixed solvent contributes to a phase-pure and homogeneous perovskite film by balancing the rate of solvent evaporation and reactant diffusion. Additionally, the NIR energy heats the large-area perovskite wet film directly and rapidly in the air, and thus controls the solvent volatilization for uniform phase transformation. As a result, this strategy enables the air-processed perovskite-silicon tandem device based on an industrial c-Si cell to achieve an efficiency of 30.95% (certified 30.6%) for an active area of 1.0 cm2 and obtain an efficiency of 27.1% for an aperture area of 110 cm2.

However, their sluggish reaction kinetics lead to irreversible conversion reaction during cycling, resulting in low compositional reversibility and rapid battery failure. To improve their electrochemical performance in AMIBs, many efforts involving structure, composition, and interface modifications have been devoted. However, there is still a lack of a systematic understanding of the reversible conversion reaction mechanism and design principle for highly compositional reversible TMC electrodes. This perspective discusses the reversible conversion mechanism and key challenges of TMCs through a combination of computational and experimental approaches. Three kinds of modification strategies, including multi-scale structure construction, fabrication of TMC-based composite, and interfacial engineering, along with their working mechanisms on promoting the reversible conversion reaction of TMCs, are comprehensively elucidated. Finally, the current general design principle for compositional reversible TMC electrodes in AMIBs is summarized, while future research opportunities are discussed.
