This study investigates the strain profile at the electrode–tissue interface under various brain displacements—vertical, lateral, diagonal, and torque—across different brain models (linear elastic, hyperelastic, and viscoelastic). The safety margin for tissue damage is assessed by evaluating a 5% strain threshold using two probe widths (30 µm and 100 µm) in tethered and floating configurations. The probe dimensions are informed by previously developed devices implanted in rats for 12 weeks, allowing to correlate the findings with existing immunohistochemical data. A comprehensive simulation studies accounting for various conditions, such as different brain displacements and physics, has not been reported elsewhere. These results challenge the conventional 5% strain threshold for tissue damage, revealing that strains below this critical limit may still pose risks depending on probe geometry and brain model. Furthermore, these simulations underscore the necessity of size-dependent micromotion models for accurate predictions in untethered conditions. This work highlights the feasibility of integrating immunohistological data into simulation studies, offering valuable insights for researchers while minimizing the need for extensive animal testing during initial probe design phases.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 9","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202401001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914650","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}

However, its hydrophilic and porous structure renders it susceptible to oxidative corrosion, sand erosion, and acid rain when exposed to outdoor environments. Therefore, developing superhydrophobic coatings with superior waterproofing properties is a critical strategy to protect concrete. Nevertheless, existing superhydrophobic concrete coatings suffer from issues, such as poor durability, complex application processes, restricted color options, and difficulties in large-scale production. Herein, a spraying method is developed that utilizes nano-SiO2, epoxy resin, cetyltriethoxysilane, and iron oxide dyes to produce a robust, corrosion-resistant, and multicolored superhydrophobic concrete coating with red, yellow, blue, and green colors. The produced coatings exhibit a water contact angle (CA) of 156° ± 1° and a sliding angle (SA) of 5° ± 1°. The hydrophobicity of the coatings arises from the synergistic effects of cetyltriethoxysilane, which provides low surface energy, and SiO2, which creates micro and nanoscale roughness on the coating surface. Meanwhile, the coating's robustness stems from the adhesive properties of epoxy resin and hydrogen-bonding interactions between SiO2 and the concrete substrate. Thus, the developed superhydrophobic coating shows significant potential for extending the lifespan of concrete building facades, enhancing decorative and waterproofing features, and ensuring surface cleanliness.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 9","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400810","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914749","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}

In the current study, the importance of the material surface is evaluated on the water uptake of a metal–organic nanotube (UMONT) crystalline solid. This material has previously demonstrated selective water uptake and reported isotherms suggested a two-step adsorption process that involved initial surface adsorption followed by pore filling. The proposed mechanism and importance of surface chemistry for water adsorption are tested by altering the surface of the UMONT with more hydrophobic surface coatings. Crystals of UMONT are coated with ammonium trifluoroacetate (ATFA), polyvinylidene fluoride (PVDF), and polyacrylonitrile (PAN), and the water adsorption behavior is analyzed through batch and flow-through experiments. Uptake experiments reveal that ATFA significantly decreased the water uptake compared to observed in pristine UMONT while polymer coatings do not impact the adsorption behavior as significantly. In addition, ATFA disrupts the water selectivity of the UMONT material, allowing both ethanol and methanol to be detected in the system. These results indicate that changing the surface layer from a hydrophilic to hydrophobic with a chemisorbed monolayer will disturb the two-step mechanism and the water uptake properties of the material.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 8","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400731","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852991","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}

However, the toxicity of AgNPs in humans and the environment is a cause of concern. To address this, AgNPs are incorporated into nanocomposites to control their release and activity. As such, it is proposed to use curli fibers as a biological scaffold to integrate AgNPs. Curli fibers are amyloid proteins present in bacterial biofilms. Due to their adherence to many surfaces, they can facilitate their interaction with a range of nanomaterials. Curli films are manufactured by crosslinking them with glutaraldehyde and subsequently synthesizing AgNPs. By changing the precursor concentrations, the content of AgNPs synthesized is modulated. Curli-AgNP films are stable in pHs between 3–11 and in different solvents for 24 h. The release of AgNPs is greatest in alkaline pHs, with practically no release in acidic conditions. Additionally, curli-AgNP films display antimicrobial activity against Escherichia coli (E. coli) and Bacillus subtilis (B. subtilis), and the same film can be re-used multiple times against growing bacterial cultures. The ease of synthesis of curli-AgNP films coupled with their impressive stability, variable AgNPs release, and strong antimicrobial properties are suitable qualities that can be exploited to aid in wound healing or water treatment applications.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 7","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400649","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787200","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 use of chitosan as an EP suppressor for graphene oxide (GO) and reduced graphene oxide (RGO) in a ferri/ferro cyanide redox probe, using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques. The CV results indicate that GO has greater pseudocapacitance than RGO does, indicating a greater abundance of oxygen-containing functional groups that facilitate stronger interfacial interactions with chitosan. By reducing the capacitive current, as shown through EIS, the sensitivity toward the Fe2+/3+ redox couple at the electrode double layer is enhanced. These findings align with density functional theory (DFT) calculations, which indicate a charge distortion favoring chitosan, thereby allowing more efficient intrinsic electron transfer within the aromatic rings of the GO/RGO graphene nanomaterials. This research holds significant potential for advancing the development of more efficient sensors and energy storage devices.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 8","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400780","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852895","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}
