High-efficiency, low-temperature ceramic wafer bonding is essential for heterogeneous semiconductor material integration, multifunctional device packaging, and MEMS technologies. This study systematically compares oxygen (O₂) and argon (Ar) plasma activation for AlN/AlN ceramic wafer bonding, revealing two fundamentally distinct activation mechanisms: (1) O₂ plasma induces surface oxidation and chemical activation through bond scission and hydroxyl formation; (2) Ar plasma enhances bonding via physical sputtering, increasing surface reactivity without inducing surface oxidation. Experimental results show that Ar plasma reduces surface roughness and wet contact angle, without oxide formation, and enables >99% bonding area with annealing below 300 °C, meeting the thermal constraints of ceramic packaging in advanced integrated circuit (IC) applications. Detailed characterization via atomic force microscopy (AFM), contact angle measurements, X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) elucidates the plasma-induced interfacial modifications. These findings advance the understanding of scalable plasma activation strategies for wide-bandgap ceramic wafer bonding, offering a robust route toward next-generation wafer-level integration.

高效、低温的陶瓷晶圆键合对于异质半导体材料集成、多功能器件封装和MEMS技术至关重要。本研究系统比较了氧（O₂）和氩（Ar）等离子体对AlN/AlN陶瓷晶圆键合的激活作用，揭示了两种截然不同的激活机制：(1)氧等离子体通过键裂和羟基形成诱导表面氧化和化学活化；(2) Ar等离子体通过物理溅射增强键合，在不引起表面氧化的情况下提高表面反应活性。实验结果表明，Ar等离子体降低了表面粗糙度和湿接触角，没有形成氧化物，并且在300°C以下退火时可以实现>；99%的键合面积，满足高级集成电路（IC）应用中陶瓷封装的热约束。通过原子力显微镜（AFM）、接触角测量、x射线光电子能谱（XPS）和透射电子显微镜（TEM）的详细表征阐明了等离子体诱导的界面修饰。这些发现促进了对宽带隙陶瓷晶圆键合的可扩展等离子体激活策略的理解，为下一代晶圆级集成提供了一条强大的途径。

This study fabricated CoCrFeNiAl high-entropy alloy (HEA) reinforced Cu-based coatings on 6061-T6 Al alloy via cold spray. The phase composition, microstructure, and mechanical properties were systematically characterized by employing X-ray diffraction, a 3D profilometer, scanning electron microscopy, energy-dispersive spectroscopy, and universal mechanical testing. Results showed that increasing the gas pressure and temperature enhanced coating densification, leading to greater thickness, reduced porosity, and a smoother surface. This improved both hardness and shear strength. Optimal parameters (5.5 MPa, 800 °C) yielded a hardness of 159.4 HV0.1 and a shear strength of 109.8 MPa. Microscopy revealed that Cu particles deformed into flattened splats, whereas HEA particles largely retained their spherical shape due to lattice distortion. About 1 μm thick diffusion layer was observed at the interfaces between HEA particle and Al alloy substrate, HEA particle and Cu particle, and Cu particle and Al alloy substrate, indicating metallurgical bonding. Fracture analysis confirmed stronger interfacial cohesion under higher parameters, evidenced by increased Al adhered to the coating fracture surfaces.

采用冷喷涂的方法在6061-T6铝合金表面制备了CoCrFeNiAl高熵合金（HEA）增强cu基涂层。采用x射线衍射、三维轮廓仪、扫描电子显微镜、能量色散光谱和通用力学测试等方法对材料的相组成、微观结构和力学性能进行了系统表征。结果表明，提高气体压力和温度可以增强涂层致密化，导致涂层厚度增加，孔隙率降低，表面更光滑。这提高了硬度和抗剪强度。最佳参数（5.5 MPa, 800℃）的硬度为159.4 HV0.1，抗剪强度为109.8 MPa。显微镜显示，Cu颗粒变形成扁平的片状，而HEA颗粒由于晶格畸变而基本保持其球形。在HEA颗粒与Al合金基体、HEA颗粒与Cu颗粒、Cu颗粒与Al合金基体之间的界面上观察到约1 μm厚的扩散层，表明HEA颗粒与Al合金基体之间存在冶金结合。断口分析证实，在较高的参数下，涂层断口表面Al的粘附量增加，界面内聚力增强。

Chromium-doped iron(III) oxide (Cr–Fe₂O₃) thin films were deposited via spray pyrolysis at 420°C with chromium (Cr) contents of 1, 5, and 10 wt%. X-ray diffraction confirmed single-phase rhombohedral iron(III) oxide (Fe₂O₃), while FE-SEM revealed grain coarsening with Cr incorporation, verified as Cr³⁺ by EDX and XPS. In addition, the optical transmission analysis yielded film thicknesses of ∼535–600 nm and direct band gaps of 2.21 eV (1%, 5%) and 2.18 eV (10%), with Urbach energies indicating minimal disorder near 5 wt% Cr. Moreover, the electrochemical impedance spectroscopy (EIS) fitted with Rs–(R2∥CPE1)–(R3∥CPE2) showed an improved high-frequency transport with doping (Rs ≈ 40 → 11 Ω·cm²; R2 ≈ 1.9 × 10³ → 1.2 × 10² Ω·cm²), but anincreased low-frequency interfacial resistance of (R3 ≈ 7.3 × 10⁴ → 3.6 × 10⁶ Ω·cm²). Then, the Mott–Schottky analysis confirmed the n-type behavior with a donor density (N_D) ≈ 3.2–3.8 × 10¹⁸ cm^–3 and a conduction-band minimum (CBM) positively shifting from 1% to 5% Cr, partially relaxing at 10%. Overall, the moderate Cr incorporation enhances the bulk transport yet increases interfacial blocking behavior, revealing a trade-off that points to the intermediate doping as the optimal compromise.

采用喷雾热解法在420℃下制备了铬掺杂铁（III）氧化物（Cr - fe₂O₃）薄膜，铬（Cr）含量分别为1、5和10 wt%。x射线衍射证实为单相菱面体氧化铁（Fe2O3），而FE-SEM显示晶粒因Cr的掺入而变粗，EDX和XPS证实为Cr3+。此外，光透射分析得到薄膜厚度为~ 535 ~ 600 nm，直接带隙为2.21 eV（1%, 5%）和2.18 eV(10%)，乌尔巴赫能量在5 wt% Cr附近显示最小的无序。此外，Rs - (R2∥CPE1) - (R3∥CPE2)的电化学阻抗谱（EIS）显示掺杂后的高频输运改善(Rs≈40→11 Ω·cm2；R2≈1.9 × 103→1.2 × 102 Ω·cm2)，但增加了低频界面电阻（R3≈7.3 × 104→3.6 × 106 Ω·cm²）。然后，Mott-Schottky分析证实了n型行为，供体密度(ND)≈3.2-3.8 × 1018 cm-3，导带最小值（CBM）从1% Cr正向移动到5% Cr，在10% Cr部分松弛。总的来说，适度的Cr掺入增强了体输运，但增加了界面阻塞行为，揭示了一种权衡，指出中间掺杂是最佳的妥协。

This work presents the results of formation of bioactive coatings on Mg-Mn-Ce alloy by plasma electrolytic oxidation (PEO) with subsequent modification with vitamin K2 and polydopamine (PDA). The formed porous coating contained calcium phosphates, which indicates improved biocompatibility. The presence of calcium and phosphorus as well as organic compounds in the coatings was confirmed by XRD, EDS and SEM equipped with FIB. During long-term exposure of the samples to SBF, a gradual decrease of Ca²⁺ and PO₄^3- in the solution was revealed, as well as a formation of biomimetic hydroxyapatite on the samples surfaces. This demonstrates the effectiveness of the created coatings as osteo-compatible ones due to the possible formation of new centers of bone tissue. A detailed study of the corrosion of the materials in physiological environments by volumetry and EIS confirms successful inhibition of dissolution of Mg alloy, opening up new possibilities for the use of Mg implants in orthopedics.

A series of Ce-modified MOF-derived Ce_xCu_1−xO_2−δ (x=0, 0.25, 0.5, 0.75) catalysts were synthesized by a self-sacrificing template method and applied for low-temperature CO-SCR. Among the tested catalysts, bimetallic Ce_0.5Cu_0.5O_2−δ exhibited the highest low-temperature denitrification activity, achieving a nearly 100% NO conversion rate in a broad temperature window from 225 to 450°C. Based on H₂-TPR and XPS, a redox cycle Ce³⁺ + Cu²⁺ ↔ Ce⁴⁺ + Cu⁺ was conducted, which was conducive to generating more adsorption centers for NO and CO. According to in situ FT-IR results, key intermediates Cu⁺-CO and N₂O were detected at 2119 and 2208 cm^-1 over Cu⁺-O_v-Ce³⁺ sites, which were enhanced by a Ce additive-induced Cu-Ce synergy effect. Furthermore, DFT calculations revealed that the bonding orbital of N 2p shifted towards the Fermi level with Ce doping, which resulted in a strong N-Cu/Ce bonding and the weakening of N-O bond, therefore increasing NO adsorption energy up to -0.71 eV on Ce_xCu_1−xO_2−δ (111). Furthermore, a typical low-temperature Langmuir-Hinshelwood (L-H) mechanism over Ce_xCu_1−xO_2−δ was discussed in detail.

采用自牺牲模板法合成了一系列ce修饰mof衍生的ceexcu1−xO2−δ (x= 0,0.25, 0.5, 0.75)催化剂，并应用于低温CO-SCR。在所测试的催化剂中，双金属Ce0.5Cu0.5O2−δ表现出最高的低温脱氮活性，在225 ~ 450℃的宽温度窗内，NO转化率接近100%。基于H2-TPR和XPS，进行Ce3+ + Cu2+↔Ce4+ + Cu+的氧化还原循环，有利于产生更多的NO和CO的吸附中心。根据原位FT-IR结果，在Cu+-Ov-Ce3+位点的2119和2208 cm-1处检测到关键中间体Cu+-CO和N2O，这是由Ce添加剂诱导的Cu-Ce协同效应增强的。此外，DFT计算表明，Ce掺杂后，n2p键轨道向费米能级移动，导致N- cu /Ce键强，N- o键减弱，从而使CexCu1−xO2−δ上的NO吸附能提高到-0.71 eV（111）。此外，还详细讨论了ceexcu1−xO2−δ上典型的低温Langmuir-Hinshelwood （L-H）机制。

TiO₂ and Al₂O₃ nanoparticles, as well as Al₂O₃@TiO₂ nanocomposite, were successfully synthesized through a simple chemical approach. XRD and XPS results confirmed the formation of rutile and α-alumina nanoparticles. TEM images showed the formation of a hexagonal TiO₂ structure with an average particle size of around 20 nm, while Al₂O₃ nanoparticles and Al₂O₃@TiO₂ nanocomposites displayed a mesoporous structure. The incorporation of these nanoparticles as small additives into cellulosic paper via a coating technique resulted in a noticeable improvement in mechanical, thermal properties and electrical insulating properties. The results obtained after 7, 14, 28, and 56 days simulate an aging process of approximately 50 years. After 56 days, the Al₂O₃@TiO₂ nanocomposite coated paper demonstrated the best overall performance in terms of tensile strength and elongation, showing improvements of 24% and 21.7%, respectively, compared to the blank coated paper. TGA results showed that the Al₂O₃@TiO₂ nanocomposite coated paper had the highest residual mass, reaching 48.78% after 56 days. Additionally, the highest breakdown voltage of 30 kV was achieved for the oil-impregnated alumina coated paper across all aged samples. This can be attributed to the high dielectric constant, excellent thermal stability, and strong resistance to electrical stress of Al₂O₃.

通过简单的化学方法，成功地合成了TiO2和Al2O3纳米颗粒以及Al2O3@TiO2纳米复合材料。XRD和XPS结果证实了金红石和α-氧化铝纳米颗粒的形成。TEM图像显示TiO2形成了平均粒径约为20 nm的六角形结构，而Al2O3纳米颗粒和Al2O3@TiO2纳米复合材料则呈现介孔结构。通过涂层技术将这些纳米颗粒作为小添加剂掺入纤维素纸中，显著改善了纤维素纸的机械、热性能和电绝缘性能。在7、14、28和56天后获得的结果模拟了大约50年的老化过程。56天后，Al2O3@TiO2纳米复合涂布纸在抗拉强度和伸长率方面表现出最佳的综合性能，分别比空白涂布纸提高了24%和21.7%。TGA结果表明，Al2O3@TiO2纳米复合涂布纸的残留质量最高，56天后达到48.78%。此外，在所有老化样品中，油浸氧化铝涂布纸的最高击穿电压达到30 kV。这可归因于Al2O3具有较高的介电常数、优异的热稳定性和较强的抗电应力能力。

The leather industry's reliance on volatile organic compounds (VOCs) and chromium poses significant health and environmental risks. Addressing the environmental and health hazards associated with conventional leather finishing, this study develops and characterizes novel water-based polyacrylate nano-emulsions for multifunctional leather treatment. Two distinct formulations, poly(butyl acrylate-co-styrene) (PBS) and poly(butyl acrylate-co-methyl methacrylate) (PBM), were synthesized and incorporated with silver (Ag-NPs) and zinc oxide (ZnONPs) nanoparticles to serve as a high-performance binder. Thermal analysis, Fourier-Transform Infrared spectroscopy (FTIR), Transmission Electron Microscopy (TEM), and a zeta sizer all verified that stable nano-emulsions with particle sizes below 300 nm and zeta potentials larger than -30 mV had been formed. Comprehensive evaluations were conducted on the treated leather's surface morphology, antibacterial efficiency, and important physical qualities, such as water vapor permeability (WVP) and mechanical strength. In comparison to the untreated leather control, leather treated with the PBM2 (2:1) formulation exhibited superior mechanical performance, specifically a 237% increase in tensile strength (reaching 76.69 kg/cm²) and a 98% increase in elongation at break (reaching 88.2%), and improvements in water permeability and hardness. The nanoparticle-integrated nano-emulsion provided excellent antimicrobial protection, achieving 68% reduction of Staphylococcus aureus (Gram-positive), 97% reduction of Pseudomonas aeruginosa (Gram-negative), and >99% reduction of Candida albicans (fungi). These findings validate the potential of this eco-friendly nano-emulsion system as a safe and effective finishing agent, offering a promising alternative for sustainable leather production.

This study aims to enhance the abrasion resistance of polytetrafluoroethylene (PTFE) through the development of composite coatings incorporating ceramic fillers: boron carbide (B₄C), black silicon carbide (B-SiC), green silicon carbide (G-SiC), and aluminum oxide (Al₂O₃). The coatings were applied to aluminum substrates and evaluated using conventional gravimetric measurements alongside a novel digital image processing (DIP) technique, offering high-resolution wear analysis. The integration of DIP with surface characterization and statistical optimization provides both visual and quantitative insights into wear evolution and abrasion behavior. The effects of filler content and dry film thickness (DFT) on abrasion performance were optimized using response surface methodology (RSM). DIP results demonstrated a strong correlation with gravimetric data (R² > 0.97), validating its effectiveness as a quantitative wear assessment tool. Optimal abrasion resistance was achieved at filler concentrations of 10–11 wt% and DFT values of 30–32 µm. PTFE-B₄C coatings exhibited the highest thermal stability and crystallinity, as confirmed by Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD), without altering the chemical structure of PTFE. By optimizing filler content and film thickness, and employing digital image processing for precise wear quantification, this research advances the development of durable PTFE composite coatings for demanding industrial applications. Overall, the study establishes a practical, data-driven framework linking surface characterization, digital analysis, and performance evaluation in advanced coating systems.

本研究旨在通过开发含碳化硼（B4C）、黑色碳化硅（B-SiC）、绿色碳化硅（G-SiC）和氧化铝（Al2O3）陶瓷填料的复合涂层来提高聚四氟乙烯（PTFE）的耐磨性。该涂层应用于铝基板，并使用传统的重量测量和新型数字图像处理（DIP）技术进行评估，提供高分辨率的磨损分析。DIP与表面表征和统计优化的集成为磨损演变和磨损行为提供了可视化和定量的见解。利用响应面法（RSM）优化了填料含量和干膜厚度对耐磨性能的影响。DIP结果显示与重力数据有很强的相关性（R2 > 0.97），验证了其作为定量磨损评估工具的有效性。填料浓度为10 - 11wt %， DFT值为30-32µm时，耐磨性最佳。傅里叶变换红外光谱（FTIR）和x射线衍射（XRD）证实，PTFE- b4c涂层具有最高的热稳定性和结晶度，且PTFE的化学结构没有改变。通过优化填料含量和薄膜厚度，并采用数字图像处理进行精确的磨损量化，本研究推动了耐用PTFE复合涂层的开发，以满足苛刻的工业应用。总体而言，该研究建立了一个实用的、数据驱动的框架，将先进涂层系统的表面表征、数字分析和性能评估联系起来。

Efficient charge transfer at the tin perovskite/conductive oxide interface remains a key challenge in the development of high-performance tin-based perovskite solar cells. In this work, we used first-principles density functional theory (DFT) simulations to explore the molecular and electronic interactions at the interface. We investigated four representative self-assembled monolayers (SAMs), namely 2PACz, Py3, MeO-2PACz, and MeS-2PACz, to determine their interaction strengths with both FASnI

and ITO surfaces. By calculating interaction energies, we identified the SAMs that most effectively anchor to the perovskite and ITO while maintaining structural compatibility. To assess defect tolerance, we simulated key intrinsic defects in the perovskite, including interstitials, antisites, and vacancies, at the interface and evaluate their thermodynamic stability as well as their influence on the interfacial electronic structure. Charge density difference analyses reveal how these defects affect the electronic landscape and hole transport properties at the molecular contact. The findings point to specific SAM candidates that enable low defect interfaces and promote favorable hole transport across the full perovskite/SAM/ITO stack, enabling rational design of next generation lead-free perovskite solar cells.

在锡钙钛矿/导电氧化物界面上的高效电荷转移仍然是高性能锡基钙钛矿太阳能电池发展的关键挑战。在这项工作中，我们使用第一性原理密度泛函理论（DFT）模拟来探索界面上的分子和电子相互作用。我们研究了四种具有代表性的自组装单层膜（sam），即2PACz、Py3、MeO-2PACz和MeS-2PACz，以确定它们与FASnI3和ITO表面的相互作用强度。通过计算相互作用能，我们确定了最有效地锚定在钙钛矿和ITO上同时保持结构相容性的sam。为了评估缺陷容限，我们模拟了钙钛矿中关键的内在缺陷，包括界面上的间隙、反位和空位，并评估了它们的热力学稳定性以及它们对界面电子结构的影响。电荷密度差分析揭示了这些缺陷如何影响分子接触处的电子景观和空穴输运性质。研究结果指出，特定的SAM候选材料可以实现低缺陷界面，并促进整个钙钛矿/SAM/ITO堆栈的有利空穴传输，从而实现下一代无铅钙钛矿太阳能电池的合理设计。

This study is the first to systematically optimize the thermal evaporation process of octadecylphosphonic acid (ODPA) self-assembled monolayers (SAMs) to enhance the performance of indium gallium zinc oxide (IGZO) thin-film transistors (TFTs). By carefully optimizing key parameters, including ODPA concentration, heating time, substrate temperature, and evaporation duration, precise control over the quality and surface hydrophobicity of ODPA SAMs is achieved, leading to the successful fabrication of high-performance IGZO TFTs. As a result, the optimized devices exhibit outstanding electrical characteristics, achieving a high field-effect mobility of 31.76 cm²V^‒1s^‒1. The underlying mechanism by which ODPA SAMs enhance device performance is thoroughly investigated. This work not only demonstrates the potential of ODPA SAMs in boosting IGZO TFT performance but also offers a valuable process reference for the future integration of SAMs in metal oxide thin-film electronics.
