Summary: An amorphous nickel-phosphide (Ni-P) thin film was produced by electroplating and its potential use as an anode material for secondary lithium batteries was investigated. The study found that thin films with higher phosphorus content exhibited greater specific discharge capacity and improved cycling stability. Furthermore, the formation of globular electrodeposits on the film's surface led to enhanced capacity and rate performance without compromising the cycle life.

Summary: In this study, a novel palladium-nickel-phosphorus catalyst supported on single atom iron carbons (SAICs) with different diameter sizes (1000 nm, 200 nm, 100 nm, 50 nm, and 20 nm) was prepared. The electrochemical tests showed that the as-prepared PdNiP/50nmSAIC exhibited excellent electrooxidation activity and stability for various alcohols (methanol, glycerol, and specially ethylene glycol) in alkaline solution, surpassing that of commercial Pd/C and other advanced Pd-based catalysts. Furthermore, the PdNiP/50nmSAIC also demonstrated faster kinetic process of ethylene glycol oxidation and enhanced anti-CO poisoning ability. This study provides a new strategy for the development of MOFs-derived multielement electrocatalyst with excellent activity and stability, and a promising future for alcohol oxidation.

Summary: By uniformly depositing Ni-P alloy nanoparticles on the surface of CNTs to form a three-dimensional conductive framework, cotton-like CNTs/(Ni-P)/S composites were prepared in this study, which can effectively improve the electrical conductivity of positive electrode materials and alleviate the 'shuttle effect'. The composites exhibited high initial discharge specific capacity and remained stable after 200 cycles.

Summary: Electroless nickel composite coatings with the addition of WS2 and Si3N4 nanoparticles show potential for high-temperature tribological applications. By increasing the WS2 dosage, the content of WS2 in the coating and the micro-hardness increased. After annealing, the crystallization process led to an increase in hardness. The main wear mechanism changed from adhesive wear to abrasive wear. The annealed Ni-P-Si3N4-WS2 coating with a WS2 dosage of 2.5 g/L exhibited excellent mechanical properties at room and high temperatures.

Summary: An annealed high-phosphorus electroless Ni-P coating was developed for precision glass molding. The optimal heat treatment condition was found to be at an annealing temperature of 600 degrees C with a heating rate of 5 degrees C/min. Machining microgrooves on the coating surface improved hardness and modulus, aiding in thermal deformation resistance and enhancing forming accuracy in precision glass molding.

Summary: Glassy carbon supported Ni/GC and amorphous Ni-P/GC electrodes were prepared and characterized. The effect of electrochemical oxidation on the electrochemical behavior was investigated. The oxidation treatment significantly affected the properties of Ni/GC electrode, while had little impact on the performance of Ni-P/GC sample.

Summary: In this paper, a novel strategy for the stereocontrolled synthesis of versatile chiral P-stereogenic alkenylphosphonamidates is reported. This strategy involves a one-pot Ni-catalyzed C-P coupling/diastereoselective hydrolysis of readily available phosphoramidites and alkenyl halides. The reaction conditions were found to exhibit chemo- and diastereodivergent behavior, and the chiral alkenylphosphonamidates obtained can be selectively derivatized for the synthesis of structurally diverse P-stereogenic compounds.

Summary: In order to solve the drilling ball phenomenon on PDC bits, wear-resistant Ni-P alloy coating and surface hydrophobic texture are used. Ni-P alloy coating is deposited on the laser-textured (rectangular, linear, and sinusoidal) surface of 42CrMo through electroless plating. The rectangular texture coating with a spacing of 150-200 μm has a maximum contact angle of 133.7 degrees in the wettability of water-based drilling fluid, which is 75.69% higher than that of 42CrMo steel. The anti-mud adhesion and erosion life have also been improved to a certain extent. This research provides important experimental results and theoretical basis for solving the drilling ball problem of PDC bits.

Summary: This study uses micro-arc oxidation (MAO) and electroless nickel-phosphorus (Ni-P) plated composite film to improve the corrosion resistance of LZ91 magnesium alloy. The results show that activation by a neutral catalyst (pH=7) maintains the original structure of the MAO coating and provides a good bonding interface for the Ni-P coating, which produces a compact and excellent corrosion resistance composite coating that provides better protection for LZ91 magnesium alloy.

Summary: In this study, yttrium-stabilized zirconia (YSZ) with different yttrium (Y) content was co-deposited with Ni-P coatings using electroless plating. The effects of YSZ doping on the microstructure, phase structure, element valence, corrosion resistance, and wear resistance of the coatings were investigated. The results show that the increase in Y content in YSZ leads to enrichment of metal oxidation states on the coating surface. The presence of YSZ also enhances the crystalline diffraction and improves the corrosion resistance and wear resistance of the coatings.

Summary: In this study, a quaternary electroless Ni-Zn-Cu-P coating with a thickness of 5 μm was successfully coated on the surface of AZ31 magnesium alloy. The controllable coating parameters were optimized using Taguchi L27 orthogonal array to maximize the microhardness of the coatings. An artificial neural network (ANN) model was developed and ANN 3-7-1 showed the highest correlation coefficient and accurately predicted the microhardness of the coatings. Surface morphology, composition, and crystallinity of the coatings were also investigated using various analytical techniques.
