The phases, microstructures, and morphologies of the superalloy subjected to LSP and ion implantation before and after high-temperature cycle oxidation are characterized using various technologies, including X-ray photoelectron spectroscopy, high-temperature cycle oxidation, scanning electron microscopy, and transmission electron microscopy. A distinct amorphous HfO2 layer, with a thickness of ≈30 nm, forms on the alloy's surface. Under the dual action of LSP and ion implantation, a large number of crystal defects, such as dislocation tangles, dislocation pile-ups, twins and subgrains, are induced, and they provide channels for the rapid formation of protective oxide films through the diffusion of metal cations. At the initial stage of high-temperature oxidation, the nucleation of oxides began at the dislocation sites. The higher the dislocation density is, the greater the formation density is. A different oxidation mechanism, in which titanium ions are preferential diffused, occurred in samples after Hf ion implantation. Compared with samples only treated by Hf ion implantation, those undergoing both LSP and ion implantation displayed oxide particles that are significantly smaller, more densely packed, and adhered more strongly to the substrate. This refined oxide layer effectively acts as a barrier, hindering the infiltration of oxygen ions into the underlying substrate.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500679","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146139215","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 investigates the effect of micropillar arrays with triangular height variations on the evaporation behavior of sessile droplets while maintaining a constant solid area fraction and similar superhydrophobic wetting properties. All fabricated substrates exhibited high static contact angles, consistent with the Cassie–Baxter wetting regime. However, evaporation behavior differed noticeably with changes in the amplitude and wavelength of the height variation patterns. Arrays with higher amplitudes and shorter wavelengths promoted a prolonged Cassie–Baxter state, allowing the droplet to retain a nearly constant contact angle over a longer duration. In contrast, substrates with lower amplitude and longer wavelengths induced a gradual transition from the Cassie–Baxter to the Wenzel state, leading to early contact line pinning and a constant contact line evaporation mode. Height variation patterns also impacted the effective water evaporation rate, independent of contact angle and droplet shape. These findings show that by adjusting height variation patterns, it is possible to manipulate evaporation dynamics while preserving overall wetting behavior. Tailoring micropillar height profiles enables precise control of evaporation while maintaining superhydrophobicity, offering new design pathways for surface engineering in droplet-based technologies.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500577","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146139555","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}

Among various plasmonic semiconductors, WO3-x allows high concentrations of oxygen vacancies (OV) and pronounced localized surface plasmon resonance (LSPR) effects, enabling continuous tuning of optical and electronic properties. However, the LSPR effect in WO3-x depends critically on OV concentration and their stability. Herein, a surface reconstruction approach (structural rearrangement forming a dense surface layer with altered stoichiometry) was employed to synthesize WO3-x nanosheets consisting of an inner layer with rich OV concentration and a dense WO3 surface passivation layer, which suppresses OV healing and thereby allows stable OV concentration during exposure in ambient atmosphere conditions or photocatalytic reactions. The as-synthesized plasmonic WO3-x semiconductor exhibits enhanced LSPR effect due to the formation of a dense WO3 passivation layer on the surface, which significantly improves the efficiency and stability of photocatalytic degradation of methyl orange under visible-near-infrared light illumination. This study provides a novel approach to improve the OV stability in plasmonic WO3-x semiconductors, offering important insights for stabilizing OV concentrations in various plasmonic semiconductors. This advancement facilitates the application of plasmonic semiconductors in fields such as photocatalysis and nano-optoelectronics.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500962","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146136195","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}

Their fabrication is challenging, as conventional ceramic thin film methods make use of polymer-incompatible high-temperature sintering. Powder aerosol deposition (PAD) offers a solvent- and sinter-free avenue toward PCCs. An unresolved key question is how the preparation route of the composite powders dictates the PAD film formation and microstructure. To address this, we investigated PAD deposition of the system polystyrene (PS)-titanium dioxide (TiO2). PS particles synthesized via emulsion polymerization are combined with TiO2 particles either through dry mixing, yielding inhomogeneous powders, or through ultrasound-assisted slurry-mixing to form homogeneous powders. When deposited on polycarbonate and steel, these powders produce fundamentally different microstructures, with organized, multilayer-like films emerging from the inhomogeneous powders, and isotropic films from the homogeneous ones. These structural differences correlate with variations in crystallite size revealed by X-ray diffraction, which provided new insights into the role of internal shock absorption of the polymeric component during PAD impact. By employing a sacrificial layer, we obtained free-standing PAD-processed PCC films, which enable accurate compositional determination by thermogravimetric analysis. The fabrication of a 100 cm2 flexible coating on a PET film illustrates the scalability and potential for barrier and membrane applications. This work provides a transferable blueprint for designing hybrid thin films by PAD with tunable properties, thus bridging between polymer and ceramic processing.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500701","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146139544","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 study, graphene-coated titanium dioxide (TiO2@G) hybrids were synthesized via carbothermal treatment and incorporated at 0.5 wt% in lithium grease, alongside pristine graphene, TiO2, and their physical mixture for comparison. Tribological and thermal behavior were evaluated using ASTM-standard testing, profilometry, transmission electron microscopy and Hamrock–Dowson line-contact film-thickness modeling. The TiO2@G-800 hybrid demonstrated an 85.7% reduction in wear scar diameter, a 22.0% decrease in operating temperature and a modest increase in calculated film thickness (∼1.5%) relative to the control. Lubrication regime analysis based on Stribeck and Tallian parameter (λ) confirmed mixed lubrication across all samples, with slightly higher λ ratios for TiO2@G-800 and graphene, consistent with improved film retention and wear protection. The superior performance of TiO2@G is attributed to its engineered core–shell morphology, wherein the graphene sheath improves interfacial lubricity and thermal conductivity while the TiO2 core provides structural reinforcement. These findings highlight nanoscale interface engineering as a promising approach for developing next-generation high-performance greases with applications in energy, transportation and advanced manufacturing.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500952","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146135835","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, even though sterilization is an indispensable procedure for medical devices to be used on patients, the process can come with certain issues. In addition to often not being very sustainable, established sterilization procedures such as autoclaving, gamma irradiation, or ethylene oxide fumigation can either damage sensitive coatings or may produce/leave cytotoxic residues on the treated objects. In this study, we demonstrate how decontaminating sensitive macromolecular coatings with plasma activated water (PAW) or plasma activated saline (PAS) can be a valuable alternative to established sterilization processes. We expose mucin-based macromolecular coatings to a PAW/PAS treatment and show that, when used at a temperature level of 50°C, both activated liquids can successfully sterilize those coatings without compromising their structural integrity and functionality. Furthermore, cytocompatibility tests do not indicate any reason for concern regarding the formation of toxic residues in response to the PAW/PAS treatment. Together, our results suggest that PAW/PAS treatment of sensitive medical devices can be a very promising technique for applications in clinical and private settings.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 3","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500823","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146148054","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}
