Conventional techniques such as ion exchange and iron-based reductive precipitation have notable limitations. This study reports that the uvanite (U2V6O21) electrode, a layered uranium-vanadium oxide, enables potentiodynamic decoupling of UO22+ and proton intercalation/deintercalation, as well as proton-induced UO22+/UO3 precipitation and dissolution reactions. Building on a comprehensive understanding of charge-transfer and transport mechanisms, we found that potentiodynamic modulation enables selective capture of uranium species using a uvanite electrode. By allowing competing cations to deintercalate at lower potentials and preventing proton deintercalation, UO3 dissolution is inhibited, achieving a high UO3 recovery capacity of 515 mg/g at 10 times the competing cation concentration. The new electrochemistry of the uvanite electrode helps develop cost-effective, sustainable battery electrodes for critical ion extraction from water.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"15 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2026-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149359270","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}

Comparing TaTm, Spiro-TTB, and TAPC shows that contact selection does not follow apparent host–dopant interaction strength derived from theoretical calculations or conventional optical, vibrational, and photoemission spectroscopies. Instead, device-level charge extraction and recombination metrics identify NDP-9-doped TaTm as the most effective contact, also yielding 20.0% in a single-junction 1.70 eV wide-bandgap cell.

While operando techniques typically probe structural or macroscopic changes, direct detection of reactive species during operation remains experimentally demanding. Here, we introduce a dynamic operando time-of-flight secondary ion mass spectrometry platform that enables continuous chemical analysis of processes in a solid-state battery under electrochemical bias. Using this approach, we directly observe a pronounced increase of the I2– signal during charging of a Li–S composite cathode containing LiI, indicating the formation of elemental iodine. Concurrent changes in the sulfur-containing ion signals suggest the involvement of iodine species in the ongoing redox processes. These results reveal transient, low-concentration species at buried interfaces undetectable by other operando techniques, offering a pathway for identifying reactive intermediates in conversion-type solid-state batteries and related electrochemical systems.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"88 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374654","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, interfacial incompatibility between PQDs and polymers from mismatched surface chemistry triggers PQD aggregation and severe photoluminescence quenching, hindering microdisplay applications. Herein, a dual-solvent screening strategy is demonstrated for I-184-initiated crosslinked PQD-PMMA photoresists to balance solubility and lead-ion coordination strength. Undesired lead-solvent intermediate formation and residual solvent accumulation are suppressed to homogenize PQD dispersion and preserve optical performance. The 20 μm green patterned film retains 93% of the initial photoluminescence quantum yield with no photoluminescence peak shift and a narrow full width at half-maximum of 16.6 nm. The PQD pattern presents sharp pixel edges, 7.10% critical dimension deviation, 97.1% replication rate, and intersection over union of 0.92. This solvent engineering enables the revitalization of conventional polymers and addresses bottlenecks in photolithographic patterning of PQD-polymer composites.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"17 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374635","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 substantially lower this barrier using industrially relevant, lamination-based encapsulation that enables, to our knowledge, the first outdoor demonstration of Sn–Pb devices. Combining polyisobutylene edge sealing with polyolefin elastomer encapsulation, we demonstrate that the lamination process is highly compatible with Sn–Pb devices, causing negligible performance loss while preserving optoelectronic quality during short-term air exposure. Under package-oriented accelerated aging, epoxy-based encapsulation fails rapidly, whereas the lamination-based package remains intact. Outdoors under tandem-relevant filtered illumination, lamination-encapsulated devices retain ∼80% of initial efficiency after 12 days, while epoxy-encapsulated devices lose all output within 6 days. By adapting manufacturable module packaging to Sn–Pb devices, this work enables their realistic field evaluation, marks a critical step toward deployable all-perovskite tandems, and strengthens confidence in their commercial viability.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"22 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149360410","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, multiphase transport within liquid-fed porous cathodes remains poorly understood. We found carbon paper and carbon cloth yielded drastically different performance, and further analysis revealed gas retention, i.e., localized and temporary entrapment of internally generated gas within the pore network, as an important transport limitation. Flow pulse and recovery experiments under galvanostatic operations showed largely reversible performance losses, while operando X-ray imaging directly visualized gas retention. Gas retention intensifies with denser electrodes, lower catholyte flow rates, and higher current densities. Guided by these observations, an interdigitated flow field was employed to enhance through-plane convection and gas removal, increasing the maximum formate partial current density to 304 mA cm–2 and enabling 120 h of stable operation. These findings establish gas management as a critical design criterion for bicarbonate electrolyzers.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"64 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2026-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149359772","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}
