Summary: The electroless plating and electrodeposition process was used to prepare a Ni-Cu-P bilayer composite film with hydrophobic properties on the Ni-P film. The introduction of Cu inhibits the growth of cellular structures, increases nucleation points, and improves the microstructure of the Ni-Cu-P films. The Ni-P/Ni-Cu-P bilayer composite film has a pinecone-like convex structure, reduces surface energy, exhibits hydrophobicity, and effectively resists external impurities and fouling, improving corrosion resistance.

Summary: Duplex Ni-P/Ni-Mo-P coating systems were developed using the electroless dual bath technique. The effect of heat treatment on the microstructural characteristics, microhardness, friction, wear, and corrosion behavior of the coatings was investigated. Heat treatment improved the hardness and corrosion performance of the coatings, but prolonged high temperature treatment resulted in surface cracks and plastic deformation.

Summary: In this study, Ni-P-Si3N4 composite coatings were developed on a low-carbon steel substrate using electroless coating method. Incorporating 20 nm Si3N4 particles in the coating resulted in fewer surface defects, while the addition of 200 nm Si3N4 particles led to significant defects on the surface of the composite. The Ni-P-Si3N4 composite developed with 20 nm nanoparticles exhibited enhanced anticorrosion characteristics compared to the composite developed with 200 nm nanoparticles.

Summary: This paper establishes an online monitoring system to investigate the performance of different materials in coal-fired boilers under low-temperature ash deposition and dew point corrosion. The results show that Ni-P coating exhibits excellent anti-fouling performance, while Ni-P-SiO2 coating excels in corrosion resistance. Coated tubes significantly reduce fouling. Based on the comparison of electrode potential, corrosion rate, and surface morphology, the materials can be sorted in terms of corrosion resistance. Therefore, the application of coated tubes in heat exchangers helps recover waste heat, improve heat transfer efficiency, extend the service life of heat exchangers, and save costs.

Summary: This research investigates the deposition of Ni-W-P-nanoTiO(2) composite coatings on API X60 low-carbon steel using the electroless method. Taguchi design and analysis of variance are employed to optimize the electroless bath parameters and assess their significance. An artificial neural network (ANN) is used for accurate prediction of the deposition rate. Surface morphology is characterized using atomic force microscopy and field emission scanning electron microscopy, while energy-dispersive spectroscopy and X-ray diffraction are employed for compositional and phase analysis. The corrosion behavior of the nanocomposite coatings is evaluated in 3.5 wt% NaCl solution through potentiodynamic polarization. The optimum combination of parameters includes a reducing agent content of 24 g/L, TiO2 nanoparticles content of 10 g/L, a bath pH of 9, and a temperature of 80 degrees C.

Summary: Co-deposition of 200-300 nm TiO2 (anatase) particles with Ni-P electroless coatings on low carbon steel was investigated. The coated specimens were annealed using microwave and electric furnace. The effects of annealing temperatures on the coatings were characterized using XRD, SEM, EDAX, and the corrosion performance was evaluated using electrochemical polarization technique. The microwave annealing method improved the corrosion performance by diffusing TiO2 particles into the matrix and reducing micro voids. The corrosion mechanisms were explained considering crystallization, phase transformation, grain size, and micro strain.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: The structure and magnetism of cobalt ferrites after Mn2+-Tb3+ co-doping were studied. Co-doped samples exhibited cubic spinel structure and spherical shape of ferrite nanoparticles. The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
