As alternatives, existing bioadhesives suffer from imprecise fabrication, limited wet tissue adhesion, and insufficient biological functionalities for effective wound management. This work proposes biomimetic hydrogel bioadhesives composed of modified natural tannic acid (TA), hyperbranched polylysine (HPL), and acrylic acid (AA), abbreviated PTLAs, to offer solutions for tissue adhesion under challenging environments (underwater, body fluids, cold, pressure), and for enhanced healthcare. These PTLAs are fabricated via 3D printing, enabling the precise and controlled production of bioadhesives that are customized in a personalized manner with great reproducibility. Inspired by molluscs, developed PTLAs exhibit robust wet and underwater tissue adhesion, outperforming commercial and many recently reported bioadhesives. Ex vivo lamb and in vivo rat models demonstrate ultrafast (5 s) and efficient sealing and hemostasis. Exceptional freeze resistance and pressure resistance further expand their applicability to extreme environments. Meanwhile, coupled with superior infection resistance, PTLAs ensure enhanced wound healthcare while sealing and hemostasis. Further, their self‐gelling feature supports dry powder adhesion/sealing applications, practical packaging, and long‐term storage. Overall, adaptive tissue‐like PTLAs present transformative potential as bio‐tapes, bio‐bandages, bio‐sealants, bio‐carriers, etc., paving the way for next‐generation bioadhesives design and enhanced healthcare solutions.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"6 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677842","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}

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.

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.

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.

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.

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. The identification of local structure evolutions and multiple-redox activations in amorphizing materials broadens the scope for designing high-energy-density cathodes.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"5 1","pages":"e07840"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669529","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}
