Summary: In this study, superhydrophobic materials were successfully fabricated using imine chemistry and modification of the amine group. These materials exhibited excellent performance in terms of water sliding angles, resistance to acids and alkali, and stability at high temperatures. A method for directed growth of superhydrophobic particles on cellulose mesh was developed, and a spray coating technique was introduced to overcome abrasion caused by prolonged use. The prepared material is a suitable and non-toxic alternative for fabrication of self-cleaning materials and superhydrophobic finish.

Summary: Researchers have developed a superhydrophobic surface with smart adhesion, which can switch between adhesion in air and oil. By alternately exposing the surface to UV irradiation and heat, the adhesion properties can be controlled. The transitions are not synchronous, with longer UV irradiation required for high adhesion in oil compared to air. This study reveals the effect of environmental media on surface-wetting/adhesion transition, providing insights for the design of novel adhesive surfaces.

Summary: A process for wet metallization on glass substrate involving adhesive electroless plating (ELP) was developed by integrating Pd nanoclusters and a TiO2 adhesion promoting layer (APL). The ELP metal film was observed to penetrate the mesoporous structure of TiO2 APL, improving adhesion. Fracture analysis showed that the metal film/TiO2/glass structure breaks inside TiO2 APL, indicating the need for further engineering developments to enhance the TiO2 APL coating.

Summary: This study reveals that the receding contact angles of droplets decrease with the decrease in the pillar spring constant. Surprisingly, densely packed pillar arrays may result in larger receding contact angles than sparsely packed pillars, which is contrary to the understanding of rigid pillar arrays.

Summary: Cellulose beads (CBs) were fabricated through mechanical agitation after cellulose extraction from palm fibers. These CBs were then coated with triethoxy(octyl)silane (TEOS) for their application in the separation of oily wastewater. The superhydrophobic CBs-g-TEOS exhibited good absorption capacities for organic oils and solvents, as well as stability and reusability in various environments. Due to their ecological qualities, low cost, and easy fabrication, coated cellulose beads with TEOS show promise for oil-water separation.

Summary: Supercooled droplet freezing on surfaces is a common phenomenon in nature and industry, but little is known about its effect on droplet-substrate interactions and the design of icephobic surfaces. This study investigates freezing of supercooled droplets on textured surfaces and identifies surface properties that promote ice expulsion. The study also explores mechanisms through which repellency falters and provides insights into the phenomenology of ice adhesion throughout freezing. The findings contribute to the design of icephobic surfaces for increased safety and sustainability in engineering applications.

Summary: A superhydrophobic TiN surface was generated through laser patterning and low-pressure technique, and the impact dynamics and fragmentation of water droplets on this surface were studied. The surface morphology and wetting property influenced the spreading and recoiling processes of droplets, leading to the formation of fingers during impact and fragmentation during retraction. The resulting fragmentation reduced the travel distance and time required for recoiling, and was attributed to modified hydrodynamics induced by the surface morphology and wetting property. Laser-processed hierarchical surface structures show potential in reducing contact time at the solid-liquid interface.

Summary: Superhydrophobic coatings with unique properties such as self-cleaning and staying dry have recently emerged in industrial and consumer markets. The stochastic nature of coating components can affect the uniformity of water repellency, and traditional contact angle goniometry may not provide accurate quantification of wetting properties. The study demonstrates that highly sensitive force-based methods can offer advantages in quantifying microscale heterogeneity in superhydrophobic coatings.

Summary: In 1948, Cassie proposed an equation for the wetting of a smooth, heterogeneous surface. This equation uses weighted averages based on the fractional surface areas and cosines of contact angles to predict the contact angle of a droplet on a composite surface. The equation has proven fundamental in understanding the wetting of superhydrophobic and superoleophobic surfaces. However, little attention has been given to the complete wetting of one surface component.

Summary: Prevention of bacterial adhesion is important in reducing biofilm formation and associated infections. In this study, a PET film was modified with silica nanoparticles and fluorinated carbon chains to create a superhydrophobic surface. However, contrary to expectations, bacterial adhesion, specifically of E. coli YadA, increased on the modified PET surfaces. This highlights the significance of material micro topography in bacterial adhesion.

Summary: Surface initiated-atom transfer radical polymerization (SI-ATRP) is a powerful tool for controlling surface properties, such as wettability. In this study, superhydrophobic self-cleaning propylene (PP) surfaces were successfully obtained by dipping PP sticks into xylene containing dispersed TiO2 nanoparticles. The method utilizes functionalized nanoparticles as initiators for styrene grafting polymerization, achieving hierarchical micro-nanostructures on PP surfaces with excellent water contact angle and hysteresis values. This cost-effective technique offers the potential for industrial scale-up and integration for different polymeric substrates.

Summary: This study investigates three preparation methods for mesoporous silica nanosupports and explores the effect of surface nature on TiO2 active sites and photocatalytic reactions. The results show that molecular imprinting enhances the exposure of catalytic species and changes the electronic properties, resulting in a narrow energy bandgap. The dopant-free nanocatalysts exhibit high catalytic activity for H2 photoproduction, with the SiTi1200 sample performing exceptionally well. The study demonstrates that tunable TiO2/SiO2 nanosystems can overcome limitations in water splitting and provide new opportunities for catalytic applications.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
