Summary: Researchers have developed a convenient UV-grafting technique to covalently attach silicone-based coatings to solid substrates. The short-time exposure to UV light results in the formation of lubricant-infused slippery surfaces (LISS), while longer exposure leads to the formation of semi-rigid cross-linked polydimethylsiloxane (PDMS) coatings. These coatings exhibit excellent resistance to corrosion and biofouling in aquatic environments. Due to its simple fabrication, low cost, rapid binding kinetics, eco-friendliness, non-toxicity to aquatic life, and excellent wetting-repellent characteristics, this technology has great potential for implementation in aquatic environments.

Summary: Slippery liquid-infused porous surfaces (SLIPS) have wide applications in coating due to their remarkable liquid repellency. The stability of the lubricant layer within SLIPS is crucial for their functionality, but it can deplete over time, leading to degradation of liquid repellency. Wetting ridge formation is a primary cause of lubricant depletion. This article presents an understanding of wetting ridges and advancements in their investigation and suppression on SLIPS, as well as explores new directions for SLIPS research.

Summary: Slippery liquid-infused porous surfaces (SLIPS) are a unique approach to prevent fouling when in contact with aqueous media, organic fluids, or biological organisms. These surfaces consist of a liquid lubricant locked within the protrusions of a textured solid. Drops immiscible to the lubricant exhibit high mobility and low-contact-angle hysteresis on these surfaces. SLIPS have promising applications in anti-fouling surfaces, drag reduction, and fluid manipulation. However, lubricant depletion poses a challenge to the real-world application of SLIPS. This review focuses on enhancing the lubricant retention abilities of SLIPS and discusses the mechanisms responsible for lubricant depletion.

Summary: The manipulation of gas bubbles in aqueous environment is of scientific and technological significance in various applications. This study introduces ferrofluid-infused orthonormal tracks (FOTs) with periodic micro-grooved structures, which exhibit anisotropic slipping behaviors of underwater bubbles along two orthogonal directions. The interfacial resistance of bubble slipping is found to be influenced by ferrofluid infusion and external driving velocities. The study also demonstrates applications such as bubble screening and bubble-assisted optical shutter based on the anisotropic slipping motion of gas bubbles.

Summary: Artificial chiral micronanostructures with strong chiroptical signals are significant for next generation photonic devices and chiroptical spectroscopy techniques. However, most of the existing chiral metallic metamaterials generate chiroptical signals dependent on photonic spin angular momentum, while those dependent on photonic orbital angular momentum remain unseen. In this work, copper microhelices with opposite handedness are fabricated using additive manufacturing and their orbital angular momentum-dominated chiroptical response is examined. They exhibit helical dichroism and hold promise in advanced chiroptical spectroscopy and photonic OAM engineering.

Summary: An active droplet manipulation strategy based on the slippery magnetic responsive micropillar array (SMRMA) is reported in this study. With the aid of a magnetic field, the micropillar array bends and induces the infusing oil to form a moving meniscus, which can attract nearby droplets and transport them for a long range. Moreover, through adjusting the arrangement of the micropillars of SMRMA, multi-functional droplet manipulation such as unidirectional droplet transport, multi-droplet transport, droplet mixing, and droplet screening can be achieved.

Summary: Structural color (SC) has great potential for information encryption and intelligent sensing, but direct writing of SCs at the micro/nano scale and color change in response to external stimuli is challenging. This study used femtosecond laser two-photon polymerization (fs-TPP) to directly print woodpile structures (WSs), showing obvious SCs under an optical microscope. The change of SCs was achieved by transferring WSs between different mediums. The influence of laser power, structural parameters, and mediums on SCs was systematically investigated, and the mechanism of SCs was explored using the finite-difference time-domain (FDTD) method. Reversible encryption and decryption of specific information were realized, holding broad application prospects in smart sensing, anti-counterfeiting tags, and advanced photonic devices.

Summary: Chiral oligomers in optics are photonic metamaterials inspired by the concept of chiral centers in chemistry. Recent research has focused on the photonic spin angular momentum (SAM)-dependent chiroptical response, but the orbital angular momentum (OAM)-dominated chiroptical response of chiral oligomers is still unknown. In this study, we demonstrate that individual three-dimensional (3D) chiral tetramers can exhibit a significant response to the photonic OAM, and we also reveal the origin of this response. Furthermore, we show that 3D oligomers with tailored geometric parameters can be fabricated using femtosecond direct laser writing for varying responses. This research has implications for chiroptical spectroscopy and photonic angular momentum engineering.
