Expanding the π-conjugation of carbazole is an effective approach to enhance the molecular dipole moment and facilitate charge extraction of SAMs. However, this strategy tends to cause poor solubility and excessive self-aggregation of SAMs. In this work, two highly efficient SAMs are developed by substituting a non-fused thiophene unit on 3,6-position of carbazole, namely (2-(3,6-di(thiophen-3-yl)-9H-carbazol-9-yl)ethyl)phosphonate (2PAThCz) and diethyl (4-(3,6-di(thiophen-3-yl)-9H-carbazol-9-yl)butyl)phosphonate (4PAThCz). The introduction of thiophene can completely alter the molecular packing behavior of SAM, promoting more compact π-π stacking and increasing dipole moment, which enhances hole transport. Furthermore, the long spacer length on 4PAThCz enable to help it achieves excellent solubility, inhibit self-aggregation, and strengthen the molecular orderliness. As a result, an impressive efficiency of 20.78% (certified as 20.45%) is achieved for single-junction organic solar cells.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"14 1","pages":"e02485"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669523","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}

Nevertheless, the H2 production efficiency of the EWS system is restricted by the sluggish four-electron transfer process of the anodic oxygen evolution reaction (OER), which inhibits its further large-scale applications. Herein, recent advances in the hybrid EWS systems that substitutes OER with the thermodynamically favorable small molecules electrooxidation reaction (SMEOR) to integrate with the hydrogen evolution reaction are reviewed. First, the catalytic mechanisms of electrocatalysts toward SMEOR, reactor configurations, and evaluation parameters are briefly summarized. Next, the advantages and characteristics of the hybrid systems of SMEOR integrated with hydrogen evolution reaction/oxygen reduction reaction are highlighted and discussed in detail, including pollutant degradation, waste plastic upgrading, production of value-added chemicals, bipolar H2 production, and electricity output. Subsequently, the optimization strategies for rationally engineering the catalysts of SMEOR are proposed. Last, the current obstacles and future expectations of the hybrid EWS systems are outlined. This review aims to stimulate the further evolution of green H2 production.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"14 1","pages":"e07842"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669601","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, current systems still struggle with limited sensing ranges and suboptimal decoupling strategies, restricting their effective multimodal sensing. To achieve broad-spectrum multimodal discriminability, a machine learning-enhanced modular ionic skin (MIS) is developed via a synergistic sensor-algorithm optimization strategy. From the sensing material perspective, process-controlled hard-segment modulation in the ionic gel enables the development of diverse ionic conductors with enhanced sensing properties: a minimum temperature coefficient of -4.00% °C⁻¹ (10-160 °C), a linear gauge factor of 2.95 (0-100%), and a maximum pressure sensitivity of 80.5 kPa⁻¹ (0-1.3 MPa). With respect to the decoupling algorithm, a data-driven decoupling model for the MIS is meticulously proposed and trained on a dedicated multi-stimuli dataset, achieving maximum decoupling ranges for temperature and pressure with prediction errors as low as 7.0%, while maintaining reliable strain detection despite temperature interference. The effectiveness and functionality of the system are demonstrated in a multimodal wearable hand kit for operator hand recognition and a robotic gripper kit for feedback, highlighting its potential in bidirectional human-robot interaction.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"36 1","pages":"e08795"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669605","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}

Herein, high-entropy hydroxides (HEH) with 3D ordered macroporous (3DOM) structure are prepared by chemical etching method with rational design. The 3DOM structure can maximize the exposure of the active sites and also facilitates bubble transport. As demonstrated by finite element analysis, the 3DOM structure modifies the spatial curvature of the catalyst, resulting in the enrichment of OH-. Moreover, the strong orbital coupling of transition metals significantly regulates the electronic structure of the catalyst, selectively adsorbs OH- at Fe sites, and inhibits the adsorption of Cl-. Thanks to these characteristics, 3DOM-HEH-300 shows the best oxygen evolution reaction (OER) performance in 1 m KOH (182 mV@100 mA cm-2, 211 mV@500 mA cm-2), and stables operation of more than 400 h. Besides, in natural seawater, it also exhibits the best catalytic activity (245 mV@100 mA cm-2, 278 mV@500 mA cm-2), which is better than similar catalysts without 3DOM structure. This work verifies the great synergistic effect of high entropy and mass transfer on the performance of OER, which also provides a new idea for constructing high-performance electrodes.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"14 1","pages":"e06068"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669521","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}

The main challenge lies in the difficulty of probing and comprehending the electronic properties of perovskite buried interfaces. Here, through broadly investigating 20 buried interfaces formed between different perovskites and organic hole or electron transport materials (HTMs or ETMs), it is revealed that the substrate-effect originates from the distinct energy-level alignments at HTM or ETM substrates. Experimental and theoretical studies reveal that this difference stems from varying proportions of two perovskite terminations, which are determined by the interaction between substrates and perovskite crystals. With such mechanism, the semiconduction type of perovskite by controlling the proportion of surface terminations is successfully tuned. These findings provide new insights into optimizing device performance through termination engineering.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"15 1","pages":"e06747"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669528","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, present LMBs still mainly rely on conventional lithium-ion batteries (LIBs) cathodes (e.g., LiFePO4 and LiNi1/3Mn1/3Co1/3O2) with limited reversible capacity (≈150 to ≈190 mAh g-1 cathode), necessitating the paradigm to achieve a new host with abundant Li+ accommodation sites. Herein, it is proposed a high-capacity amorphizing iron molybdate cathode a-Fe2(MoO4)3 (a-FMO), which can reversibly unlock Fe3+/Fe2+ and Mo6+/Mo4+ redox insertion reactions in the metastable structure. Different from its parent crystal and stoichiometric oxides mixtures, a-FMO, with its inherent metastable structure, can not only augment the lithium storage capacities with fully activated redox centers, but also attenuate the lattice confinements for Li+ ion migration. Consequently, the in-situ generated a-FMO electrode exhibited a notable reversible capacity of 254 mAh g-1 with stable cycling over 500 cycles. It endowed a specific energy density of 597 Wh kg-1 and all-climate adaptability over 60 to -40 °C benefited from the amorphizing nature, as well as negligible capacity degradation when cycling at -30 °C.

Solution processing enables the formation of electronically active percolated networks by leveraging van der Waals (vdW) interactions between individual 2D nanosheets. While effective vdW interactions are expected to minimize potential energy barriers and contact resistances between nanosheets, undesired residues from material synthesis or device fabrication processes may remain at the interface. In particular, the ideal solvent candidates for optimizing the stability of 2D dispersions are typically difficult to remove due to their high boiling points and exhibit environmental toxicity. Additionally, conventional patterning processes require multiple solvents, which can disrupt vdW interfaces and degrade device performance. To address these challenges, a comprehensive process that combines 2D dispersion preparation with a cross-linker-based direct photopatterning technique is developed using an eco-friendly green solvent. To enable this process, the stability of 2D nanomaterials and ultraviolet light-sensitive cross-linkers is thoroughly analyzed using Hansen solubility parameters. The developed process successfully enables the preparation of stable dispersions of cross-linkers and 2D nanomaterials, including graphene, molybdenum disulfide, tungsten diselenide, and hafnium disulfide, which can then be assembled via vdW interactions to create large-scale functional electronic devices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"22 1","pages":"e05917"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669603","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}

This study presents an innate immunity-guided, macrophage (MΦ)-homing nanoplatform that enables oral delivery of theranostic agents to PDAC lesions by harnessing the migratory behavior of endogenous MΦ toward tumor-derived immune cues. The nanoplatform integrates a βGlus-R848 prodrug-constructed by conjugating β-glucans (βGlus) with the immunomodulator resiquimod (R848) via a reactive oxygen species (ROS)-responsive thioketal linker-and Ag2Te quantum dots (QDs) for near-infrared II (NIR-II) imaging, forming βGlus-R848/Ag2Te nanoparticles (NPs). Upon oral administration, βGlus facilitates the selective uptake of NPs by intestinal MΦ (βGlus-R848/Ag2Te NPs@MΦ), which subsequently migrate to the tumor microenvironment (TME). There, elevated ROS levels trigger the release of R848, reprogramming tumor-associated MΦ from an immunosuppressive M2 to an immunoactive M1 phenotype. This immune activation remodels the stroma, enhances T cell infiltration, and transforms the TME into an immunoactive state, thereby improving therapeutic outcomes. Concurrently, Ag2Te QDs enable deep-tissue NIR-II imaging for real-time visualization of PDAC progression, liver metastasis, and treatment response.
