Here we show a self-adhesive high-entropy oxide sub-nanowire monolithic catalyst that overcomes both obstacles. The catalyst is synthesized under mild conditions and incorporates 14 metal elements into uniform ~1.2 nm sub-nanowires with strong intrinsic adhesion to conductive substrates, eliminating the need for external binders. It also features unconventional active sites that enable efficient and durable lattice oxygen activation while preserving structural integrity during prolonged operation. It exhibits overpotentials of 129 mV in 1 M KOH and 153 mV in 1 M KOH + seawater at 10 mA cm-2, and maintains continuous operation at 1,000 mA cm-2 for 4,700 h and 4,400 h, respectively. Integrated into an anion exchange membrane seawater electrolyser, it delivers 3,000 mA cm-2 at 1.70 V (80 °C) and operates continuously for over 3,819 h at 2,000 mA cm-2 under ambient conditions.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":" ","pages":""},"PeriodicalIF":34.9,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147840646","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}

Here we introduce a method to build artificial condensates within living mammalian cells by designing modular RNA motifs composed of a single short RNA strand. These condensates emerge spontaneously, creating RNA-rich compartments that remain separated from their surrounding environment. The RNA sequences include stem-loop domains that fold as the RNA is transcribed, and then condense in the nucleus and cytoplasm through loop-loop interactions. These sequences can be optimized and diversified, enabling the generation of distinct, non-mixing condensate populations and the programmable control of their subcellular localization. The RNA motifs can also be modified to recruit small molecules, proteins and RNA molecules in a sequence-specific manner to the RNA-rich phase. By introducing RNA linkers, we can build condensates with multiple subcompartments, whose organization can be controlled by tuning the linker stoichiometry. These artificial condensates provide a versatile platform for studying and manipulating molecular functions inside living cells.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":" ","pages":""},"PeriodicalIF":34.9,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147777053","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}

These effects arise from mismatched coordination and crystallization kinetics among mixed halides and Pb2+/Sn2+ cations. Here we establish a generalizable additive design strategy guided by hard–soft acid–base principles to synchronize nucleation and crystal growth in both wide- and narrow-bandgap perovskites. Borderline-base difluoro(oxalato)borate and hard-base tetrafluoroborate selectively coordinate wide- and narrow-bandgap perovskite precursors, respectively, balancing the crystallization kinetics of PbI2/PbBr2 and PbI2/SnI2 and producing vertically uniform perovskite films with reduced defect densities and suppressed ion migration. In situ optical and structural characterization reveals homogeneous nucleation and direct crystal growth without intermediate halide redistribution. Monolithic two-terminal tandems achieve an efficiency of 30.3% (certified, 30.3%) with improved open-circuit voltage (2.16 V) and fill factor (85.2%), retaining 92% efficiency after 1,000 h of maximum power point tracking. Flexible tandems reach an efficiency of 28.2% (certified, 28.0%). These results establish chemical hardness matching as a universal principle for controlling crystallization in different perovskite systems.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"25 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751768","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}

Despite advances in electrolyte solution engineering aimed at optimizing interphase chemistry, the fundamental understanding of the interfacial environment remains limited, preventing rational designs and molecular-level manipulation of the interface. Here we introduce a molecular engineering strategy that uses dipolar self-assembled monolayers (SAMs) on the positive electrode active material to modulate interfacial stability. By tuning the electronic structure of the SAM terminal group, we establish interfacial polarity as a descriptor governing interactions between electrodes and the liquid electrolyte solution. Via in situ nanoscale depth-sensitive surface-enhanced infrared absorption spectroscopy, we directly probe the Coulombic interactions between SAMs and liquid electrolyte’s molecular components, revealing how SAM terminal groups modulate electrolyte solution behaviour, offering a scientific basis for rational battery electrode interface molecular engineering. We also show that SAM-modified positive electrodes tested in Li metal coin cells with a glyme-based non-aqueous electrolyte solution enable improved cycling stability compared with their unmodified analogues, retaining 80% of their initial specific discharge capacity after 200 cycles at 0.15 mA cm−2 within the cell’s potential range 2.8–4.7 V at 25 °C.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"5 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147734096","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}
