Addressing these issues is essential for the development of modular, meter-scale evaporators as baseline units for industrial-scale desalination systems. This study presents a solar multi-stage interfacial evaporation (SMIE) device with a 1 m² active area designed to address the key limitations associated with large-scale operation systematically. The device integrates: (i) a scalable photothermal absorber layer based on Cu-CAT-1 metal-organic framework or carbon black, (ii) an inverted multi-stage configuration with optimized thermal insulation to reduce energy loss and enable latent heat recovery, and (iii) structured wicking channels engineered to maintain spatially uniform water transport. Under 1-sun illumination in a controlled laboratory setting, a 100 cm² prototype achieved freshwater production rates of 5.45 kg m-2 h-1 with deionized water and 3.9 kg m-2 h-1 with 3.5 wt% saline water. Outdoor testing of the full-scale 1 m² device yielded an average water production rate of 3.5 L m-2 h-1 (32 L m-2 day-1) and an evaporation efficiency of 345%. These results confirm that the proposed SMIE design maintains high performance at increased scales and under realistic environmental conditions. A techno-economic analysis further identifies the critical role of reducing material costs, particularly the photothermal absorber and porous membrane, to enhance economic feasibility. The work provides a scalable approach to solar-driven desalination, relevant for future modular deployment in distributed and off-grid water purification applications.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"18 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144901301","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}

We demonstrate that these features induce spatial heterogeneity in the widely adopted [4-(3,6-dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid (Me-4PACz) self-assembled molecules (SAMs), resulting in non-conformal PVK deposition due to poor wettability. By developing a N,N-dimethylformamide (DMF)-assisted hydrophilic-terminated SAM-reconstructed Me-4PACz interface strategy, we achieved conformal coverage of SAMs and PVK. Furthermore, we identify that the conformal PVK layer inherits substrate textures with rich defects, impeding homogeneous C60 evaporation and conformal capping. To address this, we devised a bimolecular synergistic surface self-accumulation (BSSS) strategy combining 2,3,4,5,6-pentafluorobenzylphosphonic acid (F5BPA) and p-trifluoromethylphenyl ethylamine (p-CF3PEA). These modifiers spontaneously concentrate on textured PVK surfaces to construct a uniform interfacial network that recasts the PVK surface and bridges C60 through enhanced interactions. This enables homogeneous C60 adsorption and minimizes interfacial contact losses. The resulting 2-T PVK/CIGS TSCs exhibit a power conversion efficiency (PCE) of 26.14% (independently certified 25.21%), significantly surpassing previous records.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":" 19","pages":" 8907-8917"},"PeriodicalIF":30.8,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190290","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}

Globally, AI data centers are projected to demand Gigawatts of electricity, leading to Gigatons of carbon dioxide emissions and trillions of gallons of water consumed per year. With increasing deployment of high efficiency chip cooling, which in turn raises the waste heat temperature, data center waste heat could become a Gigawatt-scale energy resource. In this perspective, we analyze the various options for using data center heat from a thermodynamic, revenue, and emissions perspective. We show that direct air capture and thermal water purification are highly promising due to their ability to efficiently capture/avoid CO2 while producing a valuable product. Using data center heat for other purposes such as heating, cooling, electricity conversion, or atmospheric water production, are shown to have lower potential for emissions reduction and economic benefit. We then discuss the advantages of waste heat-powered direct air capture and water production compared to incumbent carbon capture and desalination approaches. Importantly, we highlight key technological and scientific opportunities that can enable these impactful end uses. Lastly, we propose a new data center metric, the Energy Use Efficiency (EUE), which incentivizes waste heat reuse and shows that data centers with heat utilization can be carbon-negative and water-positive, addressing major sustainability challenges of AI.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":" 18","pages":" 8403-8413"},"PeriodicalIF":30.8,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073139","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 strong reactivity between sodium–metal and conventional liquid electrolytes leads to unstable solid electrolyte interphases, undermining battery performance and safety. To address this challenge, this work introduces a novel weakly solvating quasi-solid electrolyte. This electrolyte is fabricated via in situ polymerization of polyethylene glycol diacrylate with sodium bis(fluorosulfonyl)imide in a mixed solvent system of 2-methyltetrahydrofuran and cyclopentyl methyl ether, which enables targeted manipulation of the solvation of the sodium cation. Computational and spectroscopic analyses reveal that this design promotes anion-dominated solvation, facilitates the formation of a robust anion-derived solid electrolyte interphase, suppresses dendrite formation, and enhances stability and cell performance. Batteries using this weakly solvating solvent-based quasi-solid electrolyte achieve an average coulombic efficiency of 98.4% over 400 cycles (at 0.5 mA cm−2, 0.5 mAh cm−2 in half-cell tests) and retain a capacity of 1077 mAh g−1 (based on sulfur content) over 250 cycles when paired with sulfurized polyacrylonitrile cathodes.

The Zn2+ solvation structure of these electrolytes substantially reduces the Zn deposition overpotential relative to conventional organic systems and generates polyhedral Zn with preferential Zn(002) texturing.

In situ and ex situ experimental calculations along with theoretical calculations reveal that the presence of the NiFeB nucleus reduces the surface energy of the HIF in the H-NiFeBO shell, promoting its directional growth along the HIF and enhancing the lattice oxygen oxidation mechanism (LOM) to boost the OER activity. Additionally, the NiFeB core stabilizes the *OO-VO intermediates in the LOM pathway, enhances the reversibility of NiFeB@H-NiFeBO and averts structural collapse, thereby improving the long-term stability of the OER. The resulting NiFeB@H-NiFeBO catalyst demonstrates outstanding OER performance with a low overpotential of 212 mV at a current density of 100 mA cm−2.
