It has significant implications for energy efficiency, climate adaptation, and sustainable technology development, with applications in personal thermal management, building temperature regulation, and aerospace engineering. However, radiative cooling performance is susceptible to environmental aging and special environmental conditions, limiting its applicability in extreme environments. Herein, a critical review of extreme environmental radiative cooling is presented, focusing on enhancing environmental durability and cooling efficiency. This review first introduces the design principles of heat exchange channels, which are tailored based on the thermal flow equilibrium to optimize radiative cooling capacity in various extreme environments. Subsequently, recent advancements in radiative cooling materials and micro-nano structures that align with these principles are systematically discussed, with a focus on their implementation in terrestrial dwelling environments, terrestrial extreme environments, aeronautical environments, and space environments. Moreover, this review evaluates the cooling effects and anti-environmental abilities of extreme radiative cooling devices. Lastly, key challenges hindering the development of radiative cooling devices for extreme environmental applications are outlined, and potential strategies to overcome these limitations are proposed, aiming to prompt their future commercialization.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"67 1","pages":"324"},"PeriodicalIF":26.6,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568665","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 amorphous and intricate microstructure of HC poses significant challenges in elucidating the structure-performance relationship, which has led to persistent misinterpretations regarding the intrinsic characteristics of closed pores. An irrational construction methodology of closed pores inevitably results in diminished plateau capacity, which severely restricts the practical application of HC in high-energy-density scenarios. This review provides a systematic exposition of the conceptual framework and origination mechanisms of closed pores, offering critical insights into their structural characteristics and formation pathways. Subsequently, by correlating lattice parameters with defect configurations, the structure-performance relationships governing desolvation kinetics and sodium storage behavior are rigorously established. Furthermore, pioneering advancements in structural engineering are critically synthesized to establish fundamental design principles for the rational modulation of closed pores in HC. It is imperative to emphasize that adopting a molecular-level perspective, coupled with a synergistic kinetic/thermodynamic approach, is critical for understanding and controlling the transformation process from open pores to closed pores. These innovative perspectives are strategically designed to accelerate the commercialization of HC, thereby catalyzing the sustainable and high-efficiency development of SIBs.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"89 1","pages":"325"},"PeriodicalIF":26.6,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568657","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}

Thermoelectric technology is an emerging frontier in medical therapy that aims to achieve efficient thermal and electrical transport characteristics within a narrow thermal range for biological systems. Here, we systematically constructed biodegradable Cu2MnS3-x-PEG/glucose oxidase (MCPG) with sulfur vacancies (SV) using photothermoelectric catalysis (PTEC), photothermal-enhanced enzyme catalysis, and starvation therapy. This triggers GSH consumption and disrupts intracellular redox homeostasis, leading to immunogenic cell death. Under 1064 nm laser irradiation, MCPG enriched with SV, owing to doping, generates a local temperature gradient that activates PTEC and produces toxic reactive oxygen species (ROS). Hydroxyl radicals and oxygen are generated through peroxide and catalase-like processes. Increased oxygen levels alleviate tumor hypoxia, whereas hydrogen peroxide production from glycometabolism provides sufficient ROS for a cascade catalytic reaction, establishing a self-reinforcing positive mechanism. Density functional theory calculations demonstrated that vacancy defects effectively enhanced enzyme catalytic activity. Multimodal imaging-guided synergistic therapy not only damages tumor cells, but also elicits an antitumor immune response to inhibit tumor metastasis.

However, there are challenges in fabricating efficient methylammonium-free (MA-free) WBG PSCs by blade coating, especially its phase separation and films stability. In this work, an MA-free WBG perovskite ink is developed for preparing FA0.8Cs0.2Pb(I0.75Br0.25)3 films by blade coating in ambient air. Among various A-site iodides, RbI is found to be the most effective in suppressing the precipitation of PbI2 induced by Pb(SCN)2 while keeping the enlarged grains. The distribution of Rb suggested that the Rb ions are kept isolated with the perovskite grains during the crystallization and Ostwald ripening processes, which contributes to the formation of the large-grain WBG perovskite film with minimum non-radiative recombination. As a result, a power conversion efficiency (PCE) of 23.0% was achieved on small-area WBG PSCs, while mini-modules with an aperture area of 10.5 cm2 exhibited a PCE of 20.2%, among the highest reported for solar cells prepared with WBG perovskites via blade coating.
