Here we present a novel strategy to enhance the energy density of i-TE materials through the implementation of an asymmetric device configuration. In this approach, a polyelectrolyte, polydimethyl diallyl ammonium chloride (PDDAC), is deposited on one side of a polyvinyl alcohol (PVA) hydrogel, significantly boosting power output by leveraging the salinity gradient energy derived from a nonthermally driven diffusion process. Consequently, we achieved an impressive energy density of 52.5 ± 4.5 J m<sup>−2</sup> K<sup>−2</sup>, marking the highest value reported in this field to date. This substantial improvement is attributed to the synergistic coupling of salinity gradient energy with ionic thermoelectricity, which enhances the overall voltage and energy output by adding a voltage contribution from the salinity gradient to the ionic thermovoltage.</p>\u0000 </div>","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"11 17","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148872114","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}

To address these challenges, we propose a data-driven multi-scale coupling strategy-designed acoustic lattices (DML), achieving ultra-wideband sound absorption with minimal manual intervention and time investment, demonstrating significant potential for applications in aerospace, marine, and transportation fields. Research results demonstrate that DML obtained through data-driven forward/inverse design (reducing time cost by 99.9%) achieves an average sound absorption effect of 85% across an ultra-wideband range of 220–10 000 Hz. The near-perfect absorption band (>0.9) occupies 60.3% of the total computational frequency range. During the coupling process between microscopic thermo-viscous friction and macroscopic local resonance sound absorption mechanisms, the pressure diffusion effect effectively enhances coupling efficiency (shifting the first absorption peak 600 Hz downward).

Physiologically relevant modeling of cancer can only be achieved by adequately mimicking critical tumor promoting factors such as hypoxia, cancer stemness, metastatic potential, and drug resistance—features that are effectively captured by in vitro 3D tumor models developed using scaffold-free or scaffold-based platforms. Scaffold-based systems are particularly valuable, as they provide extracellular matrix (ECM)-mimicking physical, chemical, and spatiotemporal cues, thereby supporting the formation of robust and pertinent 3D in vitro cancer models. With the fact that breast cancer (BC) is widely growing as a life threatening cancer amongst women, advancing 3D in vitro breast cancer models is crucial for developing biologically relevant and reliable platforms to evaluate drug candidates and treatment regimens. Such platforms offer significant potential for the effective translation of anticancer therapies and personalized medicine. This perspective discusses scaffold-free and scaffold-based cell culture platforms employed to mimic breast tumors and investigate key tumor promoting factors. With special attention to hydrogels within scaffold-based systems, this review highlights recent advancements driven by artificial intelligence in the design, development, and scalability of hydrogel-assisted 3D in vitro tumor models, as well as in the detailed investigation of tumor promoting factors.

Here, analysis was conducted for different thicknesses, including 1, 2, and 3 mm, and absorption loss was measured for oblique incidence of electromagnetic waves.
