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}

The synergistic effect of fluid flow and confined volume enables fast synthesis, in 8–16 min only, while 2–3 h are needed in static mode synthesis. However, the co-integration of nanomaterials into microfluidic reactors poses challenges for their use as functional devices. Here, the issue of homogeneity of nanowire growth as well as the corresponding uniformity of the nanowire dimensions are addressed. This is demonstrated that the use of optimized tree-branched microchannel networks enables excellent homogeneity, quantified by a surface coverage of 99% across the whole area of the microfluidic reactor chamber, while it is limited to 55%–78% when using conventional microfluidic chambers. The latter also leads to severe non-uniformity of the nanowires, eventually resulting in radical changes in their morphology. On the contrary, the tree-branched microchannels lead to outstanding uniformity of the nanowires: their average diameters of 35 nm are almost constant within ± 1 nm across the whole chamber; the corresponding nanowire average length of 420 nm varies within ± 12 nm only. The proposed approach is applicable to a wide variety of other nanomaterials synthesis.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 9","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.202400827","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914724","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}

In this paper, the ability to turn a predominantly electronic conductor into an excellent mixed-ionic electronic conductor by grain boundary doping is demonstrated for nanocrystalline films of lanthanum chromite. A four-orders-of-magnitude increase in the oxygen diffusion coefficient at grain boundaries is observed, and related to local chemical changes. It is shown that grain boundary effects can be effectively exploited for technological purposes by fabricating a proof-of-concept symmetric solid oxide cell based on lanthanum chromite film electrodes. The cell is operated under reversible gas feeding conditions, exhibiting electrode self-healing characteristics.

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}

Femtosecond laser is used to etch the stainless steel surface with the single-line array, inducing the generation of periodic micro-nano structures on the laser scanning path. Then the surface energy of the specimen is lowered with fluoroalkyl silane solution to ultimately obtain the superhydrophobic sample surface with excellent anti-icing properties. The contact angle of the modified sample surface reaches up to 154°, and the rolling angle is only 4°, showing excellent superhydrophobicity. Moreover, the surface can effectively delay the freezing time of water droplets. The freezing time of the water droplet is extended by 122% compared with the original surface which is only polished, and the ice adhesion strength of the water droplet after complete freezing is only 19.4 kPa. This study provides a simple method for preparing superhydrophobic and anti-icing surfaces by single-line array femtosecond laser etching, which eliminates the complicated steps of hydrophobic pattern designing and multiple processing processes. It also provides a new idea for the preparation of superhydrophobic and anti-icing surfaces in the field of femtosecond laser etching.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 9","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400828","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914718","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}
