Formamidinium lead triiodide (FAPbI₃) perovskite has garnered significant attention due to its narrow bandgap and excellent thermal stability. However, the photo-active α-phase FAPbI₃ suffers the poor structural stability, easily transforming to photo-inactive δ-phase FAPbI₃ at room temperature, a process that is accelerated by the moisture. While numerous methods have been proposed to address this issue, most efforts have relied on glove-box conditions, substrate heating, or air-knife flow. To date, few studies have reported a strategy for fabricating highly efficient FAPbI₃ perovskite solar cells (PSCs) under humid conditions. In this study, we are the first to demonstrate the fabrication of FAPbI₃ PSCs using a one-step solution deposition method in a relative humidity of 70 % without the need for auxiliary processes or equipment, achieved through the addition of a highly volatile solvent and the incorporation of methacrylic acid (MAA) into the perovskite layer. The addition of the volatile solvent enables the fabrication of FAPbI₃ perovskite in a high-moisture environment without adversely affecting the phase transformation process. The MAA incorporation not only decreases pinholes in the perovskite layer but also passivates the deep-level defects through the interaction of carboxyl groups with formamidinium cations, resulting in a low trap-state density, high charge recombination resistance, and long charge lifetime. The thermal treatment used for phase transformation of the perovskite also induces the polymerization of MAA, which further improves the long-term stability of PSCs. This dual-functional passivation approach enables PSCs to achieve high power conversion efficiency, surpassing many previously reported values for PSCs fabricated without additional processes or specialized equipment, even under highly humid conditions.

This study delineates the development of a versatile and flexible heater achieved through the sequential coating of polycaprolactone (PCL) fibers with MXene, silver nanowires (AgNW), and Aerosil/polydimethylsiloxane (AP). The primary innovation of this research lies in the concurrent realization of self-healability at low temperatures and exceptional mechanical flexibility, biocompatibility, and robust superhydrophobicity-based waterproof properties. PCL, recognized for its biocompatibility, demonstrates self-healing capabilities under mild thermal conditions, while the MXene layer mitigates damage and deformation during the healing process by providing thermal stability and efficient heat dissipation. AgNW significantly enhances electrical conductivity, thereby facilitating efficient Joule heating. The AP layer, introduced for the first time in wearable fibrous devices, imparts superior water-repellent properties by forming a hydrophobic surface that repels water and prevents moisture penetration, effectively safeguarding the electrode material from humid environments and acidic solutions. Comprehensive evaluations indicate that the heater maintains stable electrical and thermal properties, even after enduring 50,000 cycles of bending at a radius of curvature of 500 μm, 100 h of washing, and multiple cycles of cutting and healing. The fabric-based heaters were seamlessly integrated into commercially available arm sleeves, preserving their heating functionality despite being subjected to bending motions.

The use of functionalized epoxy resins (FERs) to improve corrosion resistance in various industrial applications has grown. Covalent and noncovalent modifications are the two main techniques for functionalizing epoxy resins. The addition of hydroxyl (‒OH), amino (‒NH₂), or carboxyl (‒COOH) groups through covalent functionalization to the ERs enhances their reactivity, adhesion, and solubility of epoxy resins. Noncovalent functionalization entails adding nanomaterials such as metals, metal oxides, and carbon allotropes to the resin matrix. Functionalized ERs are more effective anti-corrosive materials in the aqueous phase and the coating. Growing solubility and more polar functional groups are responsible for FERs' improved potential to guard against corrosion in the aqueous phase. Mechanical strength, chemical and thermal stability, and corrosion resistance are traits that these alterations improve. Significant improvements in corrosion resistance have been demonstrated when epoxy resin coatings with inorganic (TiO₂, CeO₂, SiO₂, Al₂O₃, h-BN, lanthanides, etc.) and organic (G, GO, CNTs, PANI, MXenes, MOFs, PDA, BIM, LDH, polymers, etc.) additives are used. The curing agents greatly influence the efficiency of the functionalized epoxy resins. The curing environment and agent type directly affect the resin's mechanical, thermal, and chemical properties. The adhesion qualities of epoxy resins can be significantly improved by functionalized curing agents, such as those treated with silane. The present article describes the corrosion protection behavior of FERs in aqueous and coating phases and their current challenges and opportunities.

在各种工业应用中，越来越多地使用功能化环氧树脂（FER）来提高耐腐蚀性。共价和非共价改性是环氧树脂功能化的两种主要技术。通过共价官能化在环氧树脂中添加羟基（-OH）、氨基（-NH2）或羧基（-COOH），可增强环氧树脂的反应性、粘附性和溶解性。非共价官能化需要在树脂基体中添加纳米材料，如金属、金属氧化物和碳异构体。功能化 ER 在水相和涂层中是更有效的防腐蚀材料。溶解度的增加和更多的极性官能团是 FER 在水相中提高防腐蚀潜力的原因。机械强度、化学和热稳定性以及耐腐蚀性是这些变化所能改善的特性。在环氧树脂涂层中使用无机（TiO2、CeO2、SiO2、Al2O3、h-BN、镧系元素等）和有机（G、GO、CNT、PANI、MXenes、MOFs、PDA、BIM、LDH、聚合物等）添加剂后，耐腐蚀性能显著提高。固化剂在很大程度上影响着功能化环氧树脂的效率。固化环境和固化剂类型会直接影响树脂的机械、热和化学特性。功能化固化剂（如硅烷处理过的固化剂）可显著改善环氧树脂的粘合质量。本文介绍了 FER 在水相和涂层相中的防腐蚀性能及其当前面临的挑战和机遇。

A methodology to model the percolated conductive network in nanoparticle-based thin films, synthesized by means of a magnetron-based gas aggregation source, was developed and validated. Two differently sized copper oxide nanoparticles were produced by varying the diameter of the exit orifice. Comprehensive characterization of these films was performed using scanning electron microscopy, transmission electron microscopy, small-angle X-ray scattering and X-ray diffraction to determine particle morphology, size distribution, porosity, vertical density profiles, and phase composition. Using the experimental data, virtual films were generated through a data-driven stochastic 3D microstructure model that is based on a sphere packing algorithm, where the particle size distribution, porosity and vertical density profile are taken into account. The generated 3D structures have been then refined to cover the effect of oxidation of as-deposited nanoparticles and non-zero roughness of real films. A computational model incorporating a simplified adsorption model was developed to simulate the effects of oxygen adsorption on the surface conductivity of the nanoparticles. Then, the electrical conductivity of the percolated networks in these virtual structures was computed using the finite element method for various partial oxygen pressures. Simulated resistivity values were compared with experimental measurements obtained from four-point probe resistivity measurements conducted under varying oxygen partial pressures at 150 °C A discussion of the validity of the model and its ability to cover qualitatively and quantitatively the observed behaviour is included.

A series of indentation tests were carried out on superelastic (SE, Austenite) and shape memory alloy (SMA, Martensite) based NiTi alloys. Two types of indenters such as Berkovich and spherical indent radii of 5 and 10 µm were used in various indent loads on the surface of SE and SMA foils. Elastic and thermal surface recovery was estimated for the SE and SMA alloys at both indenters. SE sample shows the maximum recovery from deformation of 95 % at the load of 25–50 mN for the spherical indenter. However, SMA samples show a maximum recovery after heating on residual imprints of indent depth of 79 % at 250 mN load for spherical indenters. Elastic recovery in SE NiTi sample results from reverse phase transformation during unloading, however in SMA, this results from stress induced martensitic transformation. On thermal recovery SE shows recovery from shape memory region and martensite shows recovery from stress induced martensitic region. In multicycle tests, it was observed a first relative quick functional degradation of the material response, in terms of recovery capability, and a subsequent stabilization that typically occurs. Multicycle nanoindentation was performed for SE and SMA samples with a maximum load of 10 mN with a dwell time of 1s. SE shows elastic behaviour of the hysteresis curve that stabilizes after 10 cycles, however, SMA shows unrecovered strain with plasticity. On increment of the load up to 200 mN, the multicycle local indentation for SE represents the recovery of depth on each load, however overall, the unrecovered depth increases with load. However, in SMA, an increment of unrecovered depth was accumulated on each increased load.

Oxidative chemical vapor deposition (oCVD) is a method for synthesizing uniform and conformal thin films of conductive polymers without any solvents. The structure and properties of oCVD films can be tuned by controlling the process parameters such as the flow rates of the vapor-phase reactants, substrate temperatures, chamber pressure, inert gas flow rate, and deposition time. Although the first three parameters have been studied, the impact of the last two remains as yet unexplored. This study examines how the flow rate of nitrogen gas, an inert gas that assists the oxidant delivered into the reactor chamber, and the deposition time affect the structure and properties of oCVD film. Polypyrrole (PPy) was chosen in this study due to its versatility for many applications. The results showed that nitrogen gas primarily acts as an oxidant carrier gas, impacting the distribution of the oxidant adsorbed onto the substrates. This leads to varying structure and properties of the resultant PPy. Furthermore, nitrogen flow rate and deposition time affect the thickness and conductivity of PPy differently. Increasing nitrogen flow rate significantly improves the distribution of the oxidant, but it can also result in excessive polaronic defects. These defects can severely deteriorate the polymeric structure and reduce the conductivity. Meanwhile, extending the deposition time increases the film thickness linearly due to longer reaction time and initially enhances conductivity until it reaches a plateau. These insights can be beneficial not only for the oCVD method but also for other types of vapor-based polymerization techniques.

A new catalyst was synthesized by first immobilizing 2-amino-6-methylpyridine on a magnetic mesoporous surface (MMCM-41), followed by adding palladium nanoparticles on the modified surface. The synthesized catalyst was subjected to various characterization techniques, including Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), inductively coupled plasma optical emission spectroscopy (ICP-OES), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). Characterization studies showed spherical nanoparticles in the synthesized nanocomposite (MMCM-41@APy-Pd). These particles exhibited a high BET surface area (127.62 m² g⁻¹), an average pore size of 1.48 nm, and a significant pore volume (0.143 cm³ g⁻¹). These properties made MMCM-41@APy-Pd an effective magnetic nanocatalyst for Suzuki-Miyaura and Mizoroki-Heck coupling reactions. An extensive range of aryl halides, which have both electron-withdrawing and electron-donating groups, were investigated and showed high to satisfactory efficiency in the Suzuki and Heck cross-coupling reactions. The magnetic nanocatalyst demonstrated the ability to be employed for up to five consecutive applications with minimal decrease in its catalytic efficiency and could be effortlessly recovered from the reaction mixture.

These particles exhibited a high BET surface area (127.62 m<sup>2</sup> g<sup>−1</sup>), an average pore size of 1.48 nm, and a significant pore volume (0.143 cm<sup>3</sup> g<sup>−1</sup>). These properties made MMCM-41@APy-Pd an effective magnetic nanocatalyst for Suzuki-Miyaura and Mizoroki-Heck coupling reactions. An extensive range of aryl halides, which have both electron-withdrawing and electron-donating groups, were investigated and showed high to satisfactory efficiency in the Suzuki and Heck cross-coupling reactions. The magnetic nanocatalyst demonstrated the ability to be employed for up to five consecutive applications with minimal decrease in its catalytic efficiency and could be effortlessly recovered from the reaction mixture.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"25 ","pages":"Article 100688"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zinc oxide (ZnO) is widely employed for multifunctional applications, including memristors, and has garnered substantial interest for its potential applications in next-generation integrated memory and neuromorphic computing. However, previous ZnO based memristor device studies have shown unsatisfactory performance, due to the large number of defects and low crystallinity in ZnO films deposited through several methods. This study proposes a method to modulate oxygen vacancies by doping, and subsequently confirms optimum defects at 0.14 at % Er doping. A highly crystalline Er doped ZnO (EZO) film was prepared using sputtering at room temperature for utilization as a resistive switching layer for a memristor device prepared on a transparent ITO substrate. The prepared memristor exhibited excellent forming-less uniform switching performance with endurance exceeding 10⁴ cycles and stable retention for 10⁷ s. Forming-free resistive switching in this device was driven by an interface type model to modulate oxygen vacancies. The remarkable EZO memristor switching characteristics suggests outstanding potential for next generation memory applications with remarkable stability, reproducibility, and reliability.
