Summary: This study compares the self-cleaning performances and mechanisms of super-hydrophobic and super-hydrophilic coatings on solar photovoltaic cells. The results show that the super-hydrophobic coating has a better self-cleaning effect, effectively reducing dust deposition. The self-cleaning mechanism of the super-hydrophobic coating involves the rolling of liquid droplets to remove deposited dust particles, while the super-hydrophilic coating relies on the breakup of the liquid film.

Summary: The electrodeposition of Ni-Cu and Ni-Cu-P films on steel electrodes was controlled by activation at lower current densities and diffusion limitations at higher current densities. Hydrogen evolution reaction was more intense over Ni-Cu-P films, leading to lower efficiency compared to Ni-Cu films. The composition and morphology of the films varied depending on the deposition control and efficiency.

Summary: A one-step hydrothermal processing using a stearic-acid-based precursor medium was developed to produce super-hydrophobic and corrosion-resistant coatings for magnesium-lithium alloys. The coatings were formed through hydrothermal conversion and the concurrent formation of low surface energy materials. The obtained coating exhibited super-hydrophobicity and excellent corrosion resistance due to the multiscale microstructures and through-thickness stearates.

Summary: This study investigates the influence of different accelerating gas temperatures on the deposition performance of Ni-coated Al coatings by cold spraying. The results show that increasing the accelerating gas temperature enhances the embedding depth of Ni-coated Al particles into the Al substrate, but not on the Q235 steel substrate. Additionally, the morphology, phase composition, porosity, and thickness of the coatings are affected by the accelerating gas temperature.

Summary: Currently, the development of solar photovoltaic power generation technology is advancing rapidly worldwide in order to achieve carbon neutrality. The deposition of dust on solar photovoltaic modules is a major factor in the decline of power generation efficiency. While there have been numerous outdoor experiments and simulations investigating the factors affecting dust deposition, there is a lack of research conducted in an indoor setting and into the impact of wind direction. This paper presents three indoor wind tunnel experiments that evaluate the performance of super-hydrophobic coatings, considering wind speed, tilt angle, and wind direction. The results demonstrate that the use of super-hydrophobic coatings can significantly reduce dust deposition and improve photoelectric conversion efficiency.

Summary: The co-incorporation of Ni and Cu at specific ratios (11.01% and 3.41% respectively) has been shown to significantly improve the hardness and wear resistance of CrBN coatings, with CuO acting as a lubricating layer. However, excessive Cu content can lead to a sharp decline in hardness and weaken the wear resistance of the coatings. Therefore, Ni (11.01%) and Cu (3.41%) is the proper co-incorporation combination for enhancing the mechanical and tribological properties of the coatings.
