However, attaining both a large piezoelectric coefficient (<i>d</i><sub>33</sub>) and a high mechanical quality factor (<i>Q</i><sub>m</sub>) is generally regarded as challenging because of the inherent trade-off among these properties. In this work, the reduction of internal defects and the redistribution of the second phase in potassium sodium niobate (KNN) based composite ceramics are achieved through a heat treatment technique. This method can achieve a significant improvement of electromechanical properties (<i>d</i><sub>33</sub> = 415 pC/N and <i>Q</i><sub>m</sub> = 120), which effectively overcomes the contradiction between piezoelectric properties and mechanical losses. Structural characterizations indicated that the improved electromechanical performance of the annealed KNN composite ceramics could be attributed to the optimized internal defects and the extrinsic local stress field. These findings offer a promising route to enhance the commercial feasibility of lead-free KNN-based piezoelectric ceramics, representing significant progress in the development of high-performance and environmentally friendly piezoelectric materials.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"73 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their various interfaces and elements are purposefully engineered at the nanoscale, which is essential to enhancing their electrochemical characteristics. The exceptional catalytic efficiency observed in graphene-coated nanoparticles (NPs) with an inner high-entropy alloy (HEA) (HEA@C) is a result of the combined action of several metallic constituents. However, increasing catalytic efficiency is still a very difficult task, particularly when it comes to obtaining precise control over the composition and structure via efficient synthesis techniques. HEA@C NPs exceptional reactivity and adaptable electrochemical characteristics allow them to perform better in slow oxygen evolution (SOE) activities. The novel multilayer graphene-enhanced HEA CoNiFeCuV@C NPs electrocatalyst presented in this work is carbon-based, and transmission electron microscopy (TEM) investigations verify its efficacy. The efficiency of the oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and oxygen reduction reaction (ORR) is greatly increased by this electrocatalyst. The electrocatalytic performance of the core–shell HEA CoNiFeCuV@C NPs is remarkable for HER, OER, and ORR, even though its highly stressed lattice has structural flaws. These catalysts reach a half-wave potential of 0.87 V in 0.1 M HClO<sub>4</sub> at a moderate current density of 10 mA cm<sup>–2</sup>, with HER and OER onset potentials of 20 and 259 mV, respectively. Using cyclic voltammetry scans, the study delves deeper into the material’s evolution by examining its morphology, chemical state, and elemental makeup both before and after activation. In addition to introducing novel electrocatalysts, this study significantly enhances our understanding of the deliberate synthesis of multicomponent intermetallic high-entropy alloys.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"18 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a high-toughness and hierarchical stress-dissipating binder for Si anodes is prepared by the covalent and hydrogen bonding of poly(acrylic acid) (PAA) and a cross-linked polyurethane (CPU). The physicochemical dual-cross-linked CPU-PAA binder with high toughness, large tensile strength, and hierarchical stress dissipation improves the structural integrity of Si anodes and minimizes thickness swelling. Finite element analysis confirms that the CPU-PAA binder reduces and uniformizes the stress distribution within the Si anodes during cycling. As a result, the Si/CPU-PAA anode shows a high capacity retention of 82.3% after 150 cycles at a high current density of 5 A g<sup>–1</sup>. Moreover, the Si/CPU-PAA//LiNi<sub>0.5</sub>Co<sub>0.2</sub>Mn<sub>0.3</sub>O<sub>2</sub> full cell delivers stable cycling performance, highlighting the great potential of the CPU-PAA binder in high-energy-density LIBs.

While computational studies exist for the wettability of atomically perfect mineral substrates, actual minerals possess heterogeneities. This study employs molecular dynamics simulations to examine the impact of surface defects on the wettability of kaolinite surfaces exposed to hydrogen, methane, and carbon dioxide. The results show that siloxane surfaces become more hydrophilic as defect densities increase and that the gases can strongly affect wettability. Carbon dioxide, in particular, shows stronger adsorption on heterogeneous surfaces than hydrogen and methane. As a consequence, carbon dioxide can strongly affect wettability. Additionally, our results show that higher salt concentrations reduce water contact angle, which is important because salt is likely present in the subsurface. A machine learning classification algorithm is applied to interpret the results and develop predictive capabilities. Our findings highlight the importance of surface defects on wettability, which is essential for designing geological repositories for geo-energy applications ranging from enhanced gas recovery to carbon sequestration and intermittent hydrogen storage.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"36 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydroxyapatite incorporated into these biomaterials improves their mechanical and biological properties due to its bioactive osteoconductive nature. The objectives of this study are to synthesize and characterize polycaprolactone (PCL) scaffolds containing hydroxyapatite nanoparticles (HAn) at 1, 2.5, 5, and 7% concentrations and to determine their cytocompatibility and osteogenic potential. Fiber thickness (<i>n</i> = 240) and interfibrillar space (<i>n</i> = 8) of PCL scaffolds were characterized by scanning electron microscopy (SEM). The PCL scaffolds were evaluated concerning their thermal degradation (TGA), calcium release, and hydrophilicity (WCA). Preosteoblasts were seeded on PCL scaffolds and assessed regarding their viability (AlamarBlue, <i>n</i> = 8), collagen synthesis (SR, <i>n</i> = 8), total protein synthesis (TP, <i>n</i> = 8), alkaline phosphatase activity (ALP, <i>n</i> = 8), deposition of mineralization nodules (MN, <i>n</i> = 8), and cell adhesion (fluorescence microscopy). The data analyses of the biomaterials, including TGA, energy dispersive spectroscopy (EDS), and Fourier transform infrared spectroscopy (FTIR), were interpreted descriptively. The quantitative data were statistically analyzed (α = 5%). Scaffolds without HAn exhibited thicker fibers. The higher incorporation of HAn in the PCL scaffolds increased the interfibrillar spaces and resulted in greater P and Ca peaks (<i>p</i> &lt; 0.05), as well as broader peaks representing the P–O group (FTIR). TGA demonstrated that PCL scaffold degradation was inversely proportional to their HAn concentration. Higher percentages of cell viability were observed with the incorporation of HAn. ALP activity increased in cells seeded onto PCL scaffolds containing 2.5% HAn. Deposition of MN was directly proportional to the amount of HAn incorporated. HAn incorporated into PCL scaffolds interferes with the physicochemical properties of these biomaterials and favors in vitro osteogenesis.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"15 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
