Traditional contact angle measurements face challenges when applied to intricate surfaces like dental implants. Here, tensiometry applying the Wilhelmy plate method has been described in the last decade to offer one solution for the evaluation of complex surface geometries by quantifying apparent contact angles based on wetting forces. This study evaluates a simple setup employing the Wilhelmy balance concept for immersion angle determination. Instead of using a force sensor as in tensiometers, the wetting force is determined via changes in mass signal by means of an analytical balance available in standard laboratories. The force is thus recorded inverse to conventional tensiometry. The approach was validated on diverse geometries and extended to intricate structures, including plasma-treated dental implants. Results were compared to conventional contact angle analysis systems underlining the reliability of the method in characterizing non-planar and complex surfaces. Additionally, the method was successfully extended to the evaluation of surface energies on planar and non-planar surfaces using various solvent sets. However, results evidenced that specimen geometry can influence the measurements to such an extent that immersion contact angles can no longer be calculated due to capillary effects. An outlook suggests further exploration with a wider range of test liquids to enhance accuracy in surface energy determination.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"62 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139581407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, amorphous hydrogen‐free carbon (a‐C) film was deposited on the PTFE polymer surface by magnetron sputtering, and the a‐C/PTFE samples were irradiated with gamma ray at a maximum dose of up to 5 MGy. The evolution of the structure and nanomechanical and tribological properties of a‐C/PTFE with different irradiation doses were investigated. The structural analyses reveal that the microstructure of a‐C films irradiated at 5 MGy doses is stable. Due to the covering of the a‐C film, significant cracks appear at the surface of the a‐C/PTFE sample only when the irradiation dose reaches 5 MGy. Before and after irradiation, the nanohardness and Young's modulus of the a‐C/PTFE are significantly higher than those of PTFE. The mechanical properties of PTFE are improved by a‐C film surface treatment. The friction experiments show that the average friction coefficients of both a‐C/PTFE and PTFE remain stable around 0.175 with increasing irradiation dose. When the irradiation dose is within 1 MGy, frictional behaviors occur only on the surface of a‐C films, and the wear rate of a‐C/PTFE is as low as 9.3 × 10−5 mm3/N.m, which is significantly lower than that of PTFE. The method of a‐C film treatment on the PTFE surface can dramatically improve the irradiation resistance of PTFE.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"72 2","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139440626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In XPS terms, change to an oxidation state is commonly inferred by correlating photoemission signal with binding energy. The assumption, when classifying photoemission signals into distinct spectral shapes, is that a distribution of intensities shifted to lower binding energy is evidence of a reduction in oxidation state. In this Insight note, we raise the prospect that changes in photoemission peak shape may occur without obvious changes, determined by XPS in stoichiometry for a material. It is well known that TiO2 measured by XPS yields reproducible Ti 2p photoemission peaks. However, on exposing TiO2 to ion beams, Ti 2p photoemission evolves to complex distributions in intensity, which are particularly difficult to analyze by traditional fitting of bell-shaped curves to these data. For these reasons, in this Insight note, a thin film of TiO2 deposited on a silicon substrate is chosen for analysis by XPS and linear algebraic techniques. Alterations in spectral shapes created from modified TiO2, which might be interpreted as the change in oxidation state, are assessed in terms of relative proportions of titanium to oxygen. It is found through detailed analysis of spectra that quantification by XPS, using procedures routinely used in practice, is not in accord with the typical interpretations of photoemission shapes. The data processing methods used and results presented in this work are of particular relevance to elucidating fundamental phenomena governing the surface evolution of materials-enabled energy processes where cyclic/non-steady usage changes the nature of bonding, especially in the presence of contaminants.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"18 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139067080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The newly developed laser-based heating solution is described in detail. Its functionality is highlighted in this study in the form of a heating stage compatible with in situ ambient pressure X-ray photoelectron spectroscopy (APXPS). The proof-of-concept experiment presented in this work involves a polycrystalline nickel foil, a material of considerable interest in the scientific field due to its applications in catalysis, batteries, and electrochemistry. Owing to the intrinsic oxophilicity of nickel, the experiment targeted the high-temperature oxidation (600°C) and reduction (1050°C) that serves interest as both, a pretreatment and preparation method, and as a model reaction for the redox behavior of non-noble materials under reactive conditions. Complete and reversible surface state changes from metallic to oxide and back to metallic were achieved through stepwise variations of the gas phase composition and temperature. The heating stage showed high stability at high temperatures under reducing and oxidizing conditions, demonstrating the benefit of this design. The in situ characterization possibilities enabled by this stage will allow a better understanding of the inherent properties of materials that function at high temperatures, leading to their optimization in relevant application fields such as catalysis, materials, and surface science.","PeriodicalId":22062,"journal":{"name":"Surface and Interface Analysis","volume":"11 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139067077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The only available matrix-matched reference material for cassiterite oxygen isotope analysis is Yongde-Cst, and more reference materials are required. Here, we report Piaotang-Cst as a potential working reference material for cassiterite oxygen isotope microanalysis. Our extensive SIMS microanalysis confirmed that Piaotang-Cst is relatively homogeneous, with an average two standard deviations (2SD) of 0.49‰ (n = 626). The δ18OVSMOW value of Piaotang-Cst is 5.33 ± 0.07‰ (2SD, n = 5) as determined by a conventional fluorination isotope ratio mass spectrometer. We also demonstrated that there is no measurable matrix effect caused by the variable contents of trace elements for cassiterite oxygen isotope microanalysis.
