Summary: Surface wettability can be altered by liquid-infused surfaces (LIS) and slippery liquid-infused porous surfaces (SLIPS), by creating a new interfacial surface with repellent properties towards both polar and non-polar liquids. A two-step method is presented to transform 3D printable polymeric materials into robust SLIPS. SLIPS exhibit low rolling angles and high resistance to mechanical abrasion.

Summary: In this study, a temperature responsive paraffin-wax-infused membrane was developed to achieve both stability and slippery feature of lubricant. The paraffin wax could cover the entire membrane surface, including the micropore wall. When the paraffin wax was in liquid phase, the membrane surface exhibited a slippery state that resisted bovine serum albumin and bacterial adhesion. After three cycles of fouling and cleaning, the membrane with the optimum amount of paraffin wax showed significantly higher flux and flux recovery compared to the control membrane without paraffin wax.

Summary: From an environmental perspective, liquid-infused porous surfaces (SLIPS) have the potential to replace traditional antifouling coatings due to their green and broad-spectrum properties. However, the complex preparation process hinders their application. In this study, superhydrophobic surfaces (SHS) were created using an air spraying method and silicone oil was infused to form SLIPS. Tests showed that SLIPS had excellent antifouling performance against different types of fouling organisms, and the thermodynamic analysis confirmed the importance of air and liquid layers in this performance. The efficient and environmentally-friendly coating method developed in this study provides a reference and theoretical basis for the marine antifouling application of SLIPS.

Summary: In this study, a difunctional antifouling strategy was proposed by constructing a porous polydimethylsiloxane (PDMS) surface with a layer of aerogel and chemically grafting cinnamaldehyde. The improved structure enhanced the liquid storage stability and anti-bioadhesive ability of the coating. The grafted cinnamaldehyde acted as a chemical antibacterial and was intelligently released in harsh fouling environments, resulting in excellent long-term antifouling properties of the coating.

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.

Summary: This study reports a slippery liquid-infused porous surface (SLIPS) with super-repellent and contact-killing antimicrobial performances. The surface is prepared by a simple microphase separation technique and covalent modification to achieve bactericidal activity. The SLIPS surface shows high super-repellence against bacteria and maintains antimicrobial activity even after the lubricant is depleted. Additionally, the surface exhibits reduced coefficient of friction and can be easily applied to various substrates.

Summary: The effect of magnetic field on the wettability and mobility of droplets on structured fluids is not well understood. This study manipulates the behaviors of water droplets on a film of thermotropic liquid crystals and finds that the static wetting behavior and static friction depend on the liquid crystal mesophases, while a magnetic field has no measurable effect on these properties. However, the droplet dynamics can be affected by a magnetic field on a particular liquid crystal film and this is dependent on the direction and strength of the magnetic field. The study also proposes a scaling argument using the magnetic coherence length to interpret the results.

Summary: The study reports the fabrication of riblets and surfaces structured with aligned grooves using direct contactless microfabrication (DCM), and the ability of the riblets to function as lubricant-infused surfaces. Results show that the riblets are effective at reducing the attachment of marine bacteria, both in the as-prepared and infused form, indicating they are a potential alternative to more complicated fabricated techniques for antifouling and drag-reducing coatings.

Summary: The study found that crystals exhibit crawling motion on glass substrates with different surface properties when exposed to UV and visible light. On hydrophilic surfaces, crystals crawled faster but showed spreading, while on hydrophobic surfaces, they displayed little shape change and slower crawling motion. The interaction of melted azobenzene with glass surfaces was identified as playing a crucial role in the crawling motion, with proposed models explaining the asymmetrical conditions leading to directional motion.

Summary: This study characterizes the lubrication properties of micro- and nanogroove hierarchical patterns. The friction coefficient was found to periodically undulate along the scan lines with a period equal to the unit pattern. The presence of boundary bands affected the variation of friction coefficient, with Type H patterns exhibiting clearer undulation and a decrease in average friction coefficient at higher sliding speeds. Numerical calculations showed that oil films formed more easily on Type H patterns, and the kinetic friction coefficient decreased during parallel sliding but not during orthogonal friction.

Summary: By using inkjet printing with an aqueous dispersion of AuNRs containing a small amount of ethylene glycol (EG) as ink, vertically aligned gold nanorods (AuNRs) were quickly and easily formed. It was observed that the presence of EG in water suppressed rapid drying and convection in the droplets, which facilitated the formation of the nanostructures.
