This review elucidates cutting-edge advancements in electron transport layer materials (ETMs) and their fundamental mechanisms. Atomic defect engineering in metal oxides (e.g., F-doped SnO₂) achieves a record electron mobility 320 cm² V⁻¹ s⁻¹, whereas 2D nanolayers (e.g., MXenes, BP) empower flexible photovoltaics to reach a PCE of 24.7% with 95% operational stability across 5000 bending cycles. Tandem perovskite-silicon architectures have reached a certified 34.6% efficiency, benefiting from optimized ETL band alignment and reduced optical losses. A novel “dynamic band alignment” theory, experimentally validated through situ characterization and density functional theory (DFT) simulations, reveals real-time Fermi-level shifts at the ETL/perovskite interface, suppressing 90% of nonradiative recombination and reducing voltage loss to 0.35 V. Beyond efficiency, this review explores interface physics such as ion polarization in heterojunctions and highlights sustainable strategies such as bio-derived carbon ETL. This work establishes a roadmap for the commercialization of stable and efficient PSCs.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 18","pages":"7466 - 7491"},"PeriodicalIF":3.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 generally used nanomaterial dispersion methods commonly affect the physical size and functional group proportion of GO, thus weakening the reinforcing effects of the cement reinforcement. In the present study, the molecular dynamical (MD) simulation was employed to investigate the tensile mechanical properties of calcium silicate hydrate (C–S–H)/GO composites under different physical sizes and oxygen-containing functional group contents of GO nanosheets. The results demonstrate that the mixed GO nanosheet reinforces the C–S–H via ductility and strain energy density reinforcement from the MD perspective rather than a macroscopic peak strength improvement. Benefiting from the crack-bridging roles of GO, the ductility and strain energy density of C–S–H composites can be strengthened by up to 53.6–66.7%. A new \"danger interval\" mechanism is found in GO modification cementitious composites. With an increment of the physical size and oxygen-containing functional group content of inserted GO, the peak stress, ductility, and strain energy density of the GO/C–S–H composites all demonstrate a first declining and then rising trend, hitting the lowest value at 0.18 oxygen–carbon ratio and 0.48 size ratio with C–S–H in the <i>z</i>-axis direction. The tensile strain and stress characteristics further illustrate that inadequate nanosheet size and oxygen-containing functional group content weaken the ability of strain/stress redistribution capability of GO, thus limiting the reinforcement efficiency of the GO.

Composites are often used, but their preparation requires numerous parameters and attempts to maximize the crystalline phase or texture. To limit the number of syntheses, factor analysis is a useful tool for determining the critical parameters. This method has been applied to titania-based anodes. Biomass-derived carbon-titania composites were prepared through sol–gel synthesis followed by drying and pyrolysis under a nitrogen gas flow. Four synthesis parameters were investigated: the presence of kapok-based carbon fiber, the acid used as the sol–gel catalyst, the drying process, and the pyrolysis temperature. Owing to the Yates formula, the optimal conditions leading to an optimized specific surface area (SSA) enhancing lithium-ion diffusion are highlighted. Conclusively, whereas kapok-based carbon and supercritical drying are essential for achieving high SSAs, the effect of pyrolysis temperature on TiO₂ crystallinity depends on the acid-based sol–gel conditions, and to favor anatase instead of rutile, acetic acid should be used. As a result, this method of synthesis and implementation has made it possible to use the most suitable samples without extra conductive carbon as anodes in lithium-ion batteries and their electrochemical characteristics have been obtained using galvanostatic measurements over 40 cycles.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 17","pages":"7259 - 7272"},"PeriodicalIF":3.5,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10853-025-10874-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its conventional synthesis via the Haber–Bosch process suffers from high energy demand and CO₂ emissions. Developing efficient electrocatalysts for the nitrogen reduction reaction (NRR) under mild conditions remains a critical challenge, particularly because of the competing hydrogen evolution reaction (HER) and inert nature of N₂. Herein, we propose a novel strategy for engineering surface frustrated Lewis pairs (SFLPs) on metal-doped In₂O₃ to synergistically activate N₂ and suppress the HER. Through density functional theory (DFT) screening of 15 dopants, Al-doped In₂O₃ (Al@In₂O₃) emerged as the optimal catalyst, in which Al and adjacent In atoms functioned as spatially separated Lewis acid and base sites, respectively. This unique SFLPs configuration enables a “donation-acceptance” mechanism: Al accepts <i>π</i>-electrons from N₂ via unoccupied <i>3p</i> orbitals, while In donates electrons to polarize N₂, collectively weakening the N≡N bond. The Al@In₂O₃ exhibited a low limiting potential of − 0.560 V for the NRR and a high HER barrier (ΔG_HER = 0.936 eV), outperforming pristine In₂O₃ and other doped counterparts. Mechanistic analysis revealed that Al doping redistributes surface charges, creating electron-deficient Al sites and electron-rich In regions, which not only stabilize N₂ adsorption but also disrupt proton adsorption for HER suppression. Furthermore, orbital-resolved studies demonstrated that H⁺ adsorption during the rate-determining step (ΔG_RDS = 0.61 eV) modifies the hybridization of the N orbitals, facilitating subsequent hydrogenation. This study provides theoretical evidence of SFLPs-mediated N₂ activation on oxide catalysts, offering a universal design principle for high-selectivity NRR systems by leveraging p-block element synergies.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 17","pages":"7374 - 7392"},"PeriodicalIF":3.5,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But it will return to BM with intergranular corrosion characters for T-joint under NSSC when corrosion time enough due to that the accumulation of corrosion products at WM blocked the continued penetration of ions, and the corrosion spread toward BM.
