Nevertheless, organic ammonium iodide-derived LD perovskites typically induce undesirable interfacial deprotonation and unstable Pb–I bond exposure, ultimately compromising device stability. Herein, we introduced a robust one-dimensional (1D) perovskite interface layer through co-assembly of tetrabutylammonium (TBA⁺) cations and pseudo-halogen anions. The optimized interface configuration concurrently suppresses interfacial deprotonation and interlayer ion migration. Furthermore, triflate (CF<sub>3</sub>SO<sub>3</sub><sup>−</sup>) anions stabilize the lattice through coordinated displacement of unstable surface Pb–I bonds and anchoring of undercoordinated Pb<sup>2+</sup> sites. Finally, the champion small-area device and module achieve remarkable efficiencies of 26.47% (certified as 26.18%) and 24.29% (certified as 23.73%), demonstrating superior performance across multiple configurations.

Yet many public estimates assume non-production settings, leading to systematic overestimation. We introduce a bottom-up framework estimating inference energy from token throughput, node power, and overhead under large-scale deployment assumptions. For frontier-scale models (>200B parameters) on H100 nodes, we estimate a median energy of 0.31 Wh/query (interquartile range [IQR] 0.16–0.60), indicating that widely cited estimates are overstated by 4–20×. In test-time scaling scenarios 15× longer than typical queries, the median energy rises 13× to 3.91 Wh (IQR 2.15–7.05). Across models, serving systems, and hardware, we estimate 8–20× line-of-sight energy reductions. At data-center scale, serving 1 billion queries/day requires 0.7 GWh; if 10% are long queries, demand rises to 1.7 GWh/day. With efficiency interventions, it falls to 0.8 GWh/day, mitigating the energy impact of test-time scaling.","PeriodicalId":343,"journal":{"name":"Joule","volume":"558 1","pages":""},"PeriodicalIF":39.8,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147736005","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}

As electrochemical hydrogen production scales up to meet decarbonization goals, bubble-induced penalties, including increased ohmic resistance, blocked active sites, and mass transport limitations, have emerged as critical engineering challenges. This perspective examines bubble evolution in water electrolyzers through a fluid dynamics lens, bridging fundamental single-bubble physics with reactor-scale multiphase flows. We synthesize recent advances in nanobubble nucleation, detachment dynamics, and coalescence behavior, emphasizing how cross-disciplinary approaches and <em>in operando</em> characterization are revealing the complex forces governing bubble behavior at electrodes. Emerging strategies for bubble management are discussed, including pulsed electrolysis, artificial intelligence (AI)-assisted optimization, and novel reactor geometries. By connecting microscale bubble phenomena to macroscale electrolyzer performance, this perspective aims to guide the development of more efficient, fluid-engineered electrochemical systems.","PeriodicalId":343,"journal":{"name":"Joule","volume":"1 1","pages":""},"PeriodicalIF":39.8,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147736006","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}
