Here, a novel multifunctional hydrogel featuring a dual-crosslinked network of Poly(N-isopropylacrylamide) (PNIPAM) and Gum Arabic (GA) designed for advanced diabetic wound healing is presented. This hydrogel integrates thermoresponsive behavior, controlled bioactive release, superior mechanical strength, strong tissue adhesion, and intrinsic antibacterial and anti-inflammatory properties. Unlike traditional systems, the PNIPAM-GA hydrogel leverages complementary hydrogen bonding and hydrophobic interactions to achieve robust structural stability and tunable therapeutic delivery. The thermoresponsive transition enables temperature-triggered release of Gum Arabic, accelerating wound closure while minimizing infection risks. The tailored design of supramolecular interactions in hydrogels to enhance tissue adhesion and release of bioactive molecules represents a major advancement in wound healing technologies and provides a promising approach for next-generation wound care therapies.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 17","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500256","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032310","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}

This study explores the integration of auxetic structures with negative Poisson ratios (NPRs) as reinforcement for concrete, leveraging advances in additive manufacturing to achieve enhanced mechanical properties. Three auxetic geometries, brick-and-mortar, bowtie, and tubular, are fabricated using aluminum, stainless steel, and polylactic acid (PLA) and are evaluated experimentally and numerically. Stainless steel tubular structures achieve a record compressive strength of 233 MPa, exceeding high-performance fiber-reinforced concrete (HPFRC) at similar reinforcement volumes. In particular, auxetic aluminum tubular reinforcements demonstrate a specific compressive strength of 149 kJ g−1, equivalent to steel fiber reinforced concrete. Bowtie geometries improve toughness by redistributing stress, and tubular structures exhibit superior energy absorption and load redistribution. Finite element simulations reveal stress concentration mitigation and delay crack propagation, corroborating the experimental results. These findings highlight the significant impact of reinforcement geometry on structural performance and demonstrate that auxetic reinforcements can outperform conventional designs in strength, stiffness, and energy dissipation. This work establishes auxetic designs as a viable and promising strategy for next-generation reinforced concrete systems aimed at improving resilience and mechanical efficiency.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 17","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028445","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}

The composite films are fabricated using a supercycle approach, and the morphological, electrical, and optical properties are systematically investigated for a series of films with the cycle ratio varying from 4TiO2:1Pt to 1TiO2:4Pt. The thus deposited thin films, specifically those with 2TiO2:1Pt, 1TiO2:1Pt, and 1TiO2:2Pt ratios, consist of metallic Pt nanoparticles embedded within the anatase-type TiO2 matrix, in which the optical properties are primarily governed by the TiO2 component, whereas the electrical behavior depends on the Pt particle size and density. Notably, films with a 2TiO2:1Pt ratio undergo morphological alterations due to the nucleation of Pt nanoparticles beginning at temperatures slightly above room temperature (≈340 K), resulting in alterations in the electrical resistivity. These findings highlight the potential of ALD-grown TiO2:Pt composite thin films for applications in transparent electronics, optoelectronics, and photocatalytic systems.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 17","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500594","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032320","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}

A comprehensive understanding of the structural properties of these coatings is crucial for further optimization. This study investigates the effect of LiNbO3-related coatings on LiNi0.6Co0.2Mn0.2O2 (NCM622) CAM, focusing on the relationship between coating structure and electrochemical performance in battery cells. Therefore, three samples calcinated at 550, 350 and, 80 °C temperature are analyzed with scanning transmission electron microscopy (STEM), energy dispersive X-ray spectroscopy (EDS), and scanning precession electron diffraction (SPED) in combination with a pair distribution function (PDF) analysis. The results reveal that only an amorphous LiNbO3 coating with a calcination temperature of 350 °C significantly improves the electrochemical performance of the CAM. In contrast, at higher calcination temperatures the coating crystallizes, while at lower calcination temperatures the coating becomes a mixed niobium oxide phase, both of which correlate with reduced battery performance.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 17","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500590","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032321","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}
