Harnessing the intrinsic hydrophobicity, defect-compensation capability, and boundary lubrication potential of oil-phase components, this study develops a liquid-phase reinforcement strategy to address the interfacial challenges. Here, oily graphene oxide (TG) microdroplets (T-G) were uniformly dispersed in epoxy resin (EP) via a micellar loading-desorption method, yielding an oil-solid biphasic coating (T-G/EP). The system was further enhanced through micro-arc oxidation (MAO) interlayer integration, establishing a synergistic protective architecture (T-G/EP-on-MAO). T-G/EP-on-MAO exhibited a 92.13 % reduction in friction coefficient (from 0.623 to 0.049) and a 59.52 % decrease in wear rate (from 16.947 × 10−5 to 6.860 × 10−5 mm3/N·m) compared to EP. This enhancement originates from the in situ formation of an oil-based lubricant film enhanced by TG at sliding interfaces. After four weeks of electrochemical testing, T-G/EP-on-MAO exhibited the highest log(Rc) value (Rc = coating resistance) of 7.42. Molecular dynamics simulations unveiled dual protective mechanisms: (i) Oil microdroplets suppress free volume through enhanced molecular packing, concurrently reducing water diffusion coefficients; (ii) Water infiltration preferentially induces intermolecular hydrogen bonding over interactions with highly reactive atoms at TG/resin interfaces, thereby shielding the filler/resin interfacial fragility and restricting water mobility.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"14 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the influence of metal-support interactions on the interface between Pt and Co3O4 was disclosed during the batch ammonia borane decomposition. Co3O4 with and without decorating Pt were compared, and tested against Pt on a non-reducible oxide (PtAl2O3). The kinetic profiles were analysed using kinetic models, and both fresh and used samples were characterised using XRD, XPS, XAS, HR-TEM, CO adsorption by IR, and in situ ATR-IR. The combined study revealed an enhanced reaction rate for PtCo3O4 and its reconstruction under reaction conditions due to metal-support interaction, and disclosed the nature of the stable active sites formed under reaction conditions. Indeed, during the reaction, metallic Pt re-distributed, and the H-spillover to the support reduced the surface of Co3O4, leading to Pt clusters on Co(II)-enriched Co3O4. Atomic-scale insights on the surface redox properties of the catalysts were then obtained through DFT, and the modification of PtCo3O4 was attributed to the facile reduction of octahedral Co(III) ions at the metal/oxide interface, and rationalised as a consequence of charge transfer from Pt to Co3O4.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"20 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, defective n-type BaSi2 layers hinder BaSi2 homojunction solar cells from achieving higher conversion efficiencies. In recent years, in situ doping of arsenic (As) has been investigated to form n-type BaSi2 layers. However, a-axis-oriented As-doped BaSi2 epitaxial layers grown by molecular beam epitaxy (MBE) have a low electron concentration. The donor activation of As-doped BaSi2 layers grown by MBE was then evaluated. The highest donor activation ratio in this study was found to be approximately 14%. To clarify the reason for this, we used first-principles calculations to evaluate the adsorption of As2 used in the MBE growth on BaSi2 (1 0 0) surface and the As-related defects in bulk BaSi2. The calculations reveal that adsorbed As2 tend not to dissociate into singular As adatoms. Furthermore, the 2 AsSi defect complex, which has the lowest formation energy compared to other As-related defects, was found to deactivate the donor based on its electronic structure. This study provides valuable insight into donor deactivation in As-doped BaSi2 layers and serves as a starting point for future investigations on how to control it.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"99 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We systematically studied the relationship between the composition of In-Ga-Zn liquid alloys and the composition of 2D IGZO films and clarified the possible doping mechanism. It was found that the surface film composition was primarily governed by the Gibbs free energy generated from oxide formation. Importantly, Zn and Ga possess a strong and similar competitive oxidation behavior in the oxidation process of liquid InZnGa alloy, leading to the segregation of Ga2O3 and ZnO in the oxide skin of InZnGa alloy. In this case, we control the micro doping level of Zn and Ga to realize the composition tailoring of 2D IGZO films. Additionally, this study also reveals that increasing the Zn content in the film reduces the band gap width, increases channel current, and shows a trend where conductivity and carrier mobility increase. In contrast, the increases of Ga content results in an obvious decline of electrical performance for 2D IGZO films.

The role of oxygen species in catalytic oxidation of ethyl acetate (EA) was also elucidated. As a result, the monolithic catalyst with Co/Cu molar ratio of 1/2, labeled as CoCu2Ox-NF, exhibited the highest conversion rate for EA oxidation (T99 = 230 °C, GHSV = 3000 h−1). The results of characterization show that its robust catalytic performance could be attributed to superior reducibility, sufficient Co3+ species and high mobility of active oxygen. In addition, the larger surface area and pore volume were also beneficial to catalytic performance due to increased gas diffusion. The characterization results of fresh and used catalysts and the study of reaction mechanism showed that lattice oxygen species played an important role in EA oxidation process which accelerated the EA activation and deep oxidation of carboxylate species over CoCu2Ox-NF. As expected, the CoCu2Ox-NF catalyst also presented good stability over EA oxidation in the presence of toluene as well as o-xylene. Hence, CoCu2Ox-NF possessed satisfactory universality and long-term durability, which is a promising catalyst for industrial application.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"165 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental results showed that optimized dual-channel-layered IAZO(1:0.1:1)/ IAZO(1:0.3:1) TFTs obtained a high carrier field-effect mobility (μFE) of 42.3 cm2/Vs, a subthreshold swing (SS) of 131 mV dec-1 and an Ion/Ioff of 1.6 × 107.
