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}

First, TiO2 nanotubes are processed on a titanium substrate via anodic oxidation. The anodized surface was then modified by ethanol, distilled water, and trimethoxy(propyl)silane (TMPSi) to reduce its surface energy. Krytox GPL 105 Oil was then infused on the prepared surface. The prepared samples were then characterized by field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Attenuated Total Reflectance Fourier-Transform Infrared (ATR-FTIR), water contact angle measurement (WCA), polarization measurements, electrochemical impedance spectroscopy (EIS) analyses, and also some related tests regarding treatment stability and durability of the surface including water flotation, abrasion with SiC grit paper, adhesive tape peeling, and surface bending were carried out. Also, the anti-icing properties of the SLIPS sample were investigated. Water contact angle measurement confirms that titanium's anodic oxidation makes the surface more hydrophilic, reducing the WCA to 49°. By modifying the surface, the WCA reached 166° and the surface became superhydrophobic. After Krytox GPL 105 Oil infusion, the WCA decreased to 118°. test results indicate that the corrosion current densities measured for titanium, anodized titanium, and SLIPS titanium samples were 3.165 × 10−7, 1.884 × 10−7, and 7.053 × 10−8, respectively.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 7","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400616","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787284","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}

XPCI's main application is so far focused on medical areas at relatively low energies (< 100 keV). The translation to higher energy for industrial applications, where energies above 150 keV are often needed, is hindered by the lack of masks/gratings with sufficiently thick gold septa. Fabricating such structures with apertures of tens of micrometers becomes difficult at depths greater than a few hundreds of micrometers due to aspect ratio-dependent effects such as anisotropic etching, and preferential gold (Au) deposition at the top of the apertures. In this work, these difficulties are overcome by Deep Reactive Ion Etching optimized by a stepped parameters approach and bismuth-mediated superconformal filling of Au, ultimately resulting in 500 µm deep silicon masks filled with Au at bulk density. The obtained masks, tested in an Edge Illumination XPCI system with a conventional source and a photon-counting detector, show good agreement with simulations at different energy thresholds. They also demonstrate a higher phase sensitivity for highly absorbing objects when compared to lower aspect ratio masks, proving their potential for industrial non-destructive testing.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 8","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400749","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852742","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 this work, an amphiphilic double-crystalline polyethylene-b-polyethylene oxide (PE-b-PEO) block co-oligomer is used. A crystallization mechanism of the short-chain BCP in combination with neutral wetting of the functionalized substrate surface that permits to form edge-on, extended chain crystal lamellae with enhanced thermodynamic stability. In situ atomic force microscopy (AFM) analysis along with surface energy considerations suggest that upon cooling from the polymer melt, the PE-b-PEO first forms a segregated horizontal lamellar morphology. AFM analysis indicates that the PEO crystallization triggers a morphological transition involving a rotation of the forming extended chain crystals in edge-on orientation. Exposing their crystal side facets to the top surface permits to minimize their interfacial energy and form vertical nanostructures. Moreover, the edge-on lamellae can be macroscopically aligned by directed self-assembly (DSA), one necessity for various nanotechnological applications. It is believed that the observed mechanism to form stable edge-on lamellae can be transferred to other crystallizable short chain BCPs, providing potential pathways for sub-10 nm nanotechnology.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 6","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400661","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645817","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}
