Summary: This article reviews factors and mechanisms that affect the release of soils and impurities from cellulosic surfaces. Cellulosic substrates provide advantages for the release of contaminants due to their hydrophilic and permeable nature, but they also allow contaminants to enter internal crevices and pores. The article also discusses detergent theory and the role of cellulose in detergent formulation.

Summary: By surface engineering and fine-tuning liquid-solid adhesion, it is possible to achieve superhydrophobicity without lowering the Leidenfrost point. Water on superhydrophobic surfaces comprising doubly reentrant pillars (DRPs) can exceed that on hydrophilic and even superhydrophilic surfaces in terms of the Leidenfrost point.

Summary: Rock wettability is a key factor in the storage of hydrogen, affecting its capacity and safety. The study found that under realistic storage conditions, the surface of bituminous coal exhibited weak water-wettability. The pressure of hydrogen increased the contact angles of brine on the coal surface at 25 degrees C but had no impact at higher temperatures. A thermodynamic model was proposed to describe the observed behavior, supporting the development of large-scale geostorage technologies for hydrogen.

Summary: The wetting behavior of metakaolinite aluminum and silicon basal surfaces was studied using molecular dynamics simulations. It was found that dehydroxylation during calcination weakened the interlayer attraction, leading to particle breakup and increased specific surface area. The altered wettability was attributed to water-clay interactions mechanisms.

Summary: This paper reports experimental measurements of advancing and receding contact angles for H-2/water system in microfluidic chip with different channel widths. Results show that contact angles decrease with increasing channel widths and N-2/water and CO2/water systems exhibit similar characteristics as H-2/water system.

Summary: The aim of this study was to quantify the surface wettability of metallic surfaces covered with sprayed paints. The results showed that the treated surfaces exhibited hydrophobic water/solid interactions and the surface roughness and heterogeneity affected the wettability. The findings are important for surface-mediated process studies such as lubrication, liquid coating, and thermoflow.

Summary: Hydrophobic surfaces modified by pathogens in agricultural production reduce the utilization of pesticides, and surfactants are commonly added to improve wetting and spreading properties. This study found that nonionic surfactants are more effective than cationic surfactants for improving the wetting and spreading of pesticide solutions on cucumber powdery mildew leaves.

Summary: Interactions between water and solid substrates are crucial in nature and industry. Surface charges can significantly affect the wettability of water, even in small amounts. However, these surface charges do not have a significant impact on the structure of interfacial water or the morphology of droplets, while the adsorption of organic contaminants from aerosols can notably decrease the wettability of solid surfaces.

Summary: The nepenthes-inspired lubricant-infused surface (LIS) is a novel repellent surface with self-healing, self-cleaning, pressure stability, and ultra-slippery properties, and has shown great promise in microfluidics. Recent developments have focused on droplet manipulation on LIS with different mechanisms induced by various external stimuli, such as thermal, light, electric, magnetic, and mechanical force. The properties of the droplet, lubricant, and substrate on LIS determine the droplet condition, and droplet manipulation can be achieved through altering slipperiness, electrostatic force, and wettability. Applications in various fields, including microreactors and microfluidics, have also been discussed.
