Summary: This paper studies the characteristics of oil mist particle deposition and oil film flow in electrostatic precipitators (ESP) based on deposition experiment data. The results show that the oil film thickness is thin on the electrode plate with high current density, and thick at the inlet of ESP and the corresponding collection plate in the middle of the adjacent electrode wires. It is also found that increasing the inlet velocity or decreasing the applied voltage can result in a more uniform distribution of the oil film and an increased oil holding capacity of the electrode plate.

Summary: This work proposes a mechanism that considers the vortex motion of a liquid inside an emulsion droplet during its collision with a wall. The motion of the liquid leads to increased dissipative energy losses, which affect spreading, corona splashing, and droplet relaxation. The study also found that the equilibrium shape of the droplet during liquid relaxation is influenced by the temperatures of the liquid and wall.

Summary: An ultra-flat heteroepitaxy α-Ga2O3 thin film, with a root mean square (RMS) roughness of 0.309 nm and high crystallinity, was successfully obtained on a c-plane sapphire substrate using mist chemical vapor deposition. The growth rate was calculated as 13.22 nm min(-1) and the bandgap of the transparent film was determined to be 5.10 eV. This high quality, wide bandgap heteroepitaxy α-Ga2O3 thin film represents a significant advancement for the preparation of high power and optoelectronic devices.

Summary: A 5-nm-thick Mg0.05Sn0.95Ox thin film deposited using mist chemical vapor deposition serves as a channel layer for TFT. Compared to SnO2, Mg0.05Sn0.95Ox enhances crystallinity, reduces oxygen deficiencies, and widens the energy bandgap. The Mg0.05Sn0.95Ox-based TFT exhibits higher field-effect mobility, steeper subthreshold slope, and more stable electrical performance, making it a promising material for high electron mobility TFT applications.

Summary: The research focused on improving the dry friction and wear performance of aluminum alloys through a combination of texturing pretreatments and lubricant films. The study showed that the sample with 100μm spacing texture and PTFE/PPS film exhibited the best anti-wear effect during dry reciprocating sliding, increasing wear life by 10% and reducing wear track width and adhesion width by 35% and 25%, respectively.

Summary: The oxygen deficiency-rich TiO2/oxygen deficiency-poor TiO2 stacking structure is used as a resistive switching layer in resistive random access memory. The resistance of the memory can be switched by forming and breaking filament paths composed of oxygen deficiencies. The inclusion of the oxygen deficiency-poor TiO2 layer limits the number of filament paths, improving the memory window and endurance. The stacked structure annealed at 600°C exhibits the largest memory window, enduring switching operation, and long retention time.

Summary: Advanced cooling techniques are important for gas turbines to increase efficiency. Mist-assisted film cooling provides an innovative solution for cooling high-temperature gas turbine blades. This numerical study investigates the relationship between mainstream turbulence intensity (Tu) and mist characteristics, and reveals that high Tu significantly enhances the cooling effect of mist.

Summary: Different scan pitches and laser powers were used to texture stainless steel substrates with a checkboard pattern using a NIR laser. The as-textured surfaces showed hydrophilic properties but displayed strong superhydrophobicity after being exposed to air for 7-15 days due to reduced oxygen content. Thin-film Ag, Cu, Zn, and Al coatings were then applied on the textured surfaces. The sputtered Ag and Cu films improved hydrophobicity, while the Zn and Al coatings increased hydrophilicity. All coatings improved corrosion resistance and aging in air further enhanced the hydrophobicity.

Summary: In this study, Cu2SnS3 (CTS) thin films were prepared using a dual-source fine channel mist CVD method. By adjusting the hot plate temperature and reducing the lift gas flow rate, CTS thin films with suitable morphology for solar cells were obtained without the need for a vacuum apparatus or a sulfurization process.
