Summary: This study proposes a strategy for bubble transport in an asymmetric hexagonal cage (ASHC) under antibuoyancy conditions. By adjusting the structural parameters of the cage, the transport efficiency of bubbles can be greatly improved. Additionally, the study demonstrates that long-distance transport and controllable merging of bubbles can be easily achieved by cascading multistage ASHC structures. This research provides a simple, low-cost, extensible, and versatile construction for bubble transport for both fundamental research and practical applications.

Summary: Floating islands are commonly used for ecological remediation of urban waters and contribute to landscape decoration and beautification. This study analyzed the roles of floating islands in water purification, urban aesthetics, and their potential association. Different plant-based floating islands were constructed for lake water treatment, using biochar as fillers for coordination and capacity enhancement. The study also analyzed the effects of floating islands on urban aesthetics and proposed design considerations such as plant collocation, spatial layout, cultural background, and contact with nature. This work provides new insights into the construction of floating islands for water purification and enhancing the beauty of urban landscapes, ultimately improving the overall quality of the living environment.

Summary: A robust aggregation-induced emission luminogen photoaddition-fragmentation chain transfer (PET-RAFT) polymerization was investigated, resulting in the preparation of a variety of well-defined polymers with narrow polydispersities (D < 1.20). The use of low concentrations of a donor-acceptor (D-A) type aggregation-induced emission luminogen as a photocatalyst enabled polymerization under visible light at ambient temperature. Previous studies have mainly focused on organic solvents, with fewer investigations conducted in aqueous environments. This study successfully demonstrated the polymerization strategy in water with or without oxygen, leading to the synthesis of structure-controlled polymers. Furthermore, the fluorescence intensity of DCDPP-2TPA increased linearly with the degree of polymerization.

Summary: Compared with aqueous single-ion batteries, rechargeable aqueous hybrid ion batteries, especially Li+/Zn(2+) hybrid ion batteries, are gaining attention due to their low cost, high operating voltage, and energy density. However, the decomposition of water and the growth of Zn dendrites limit their working voltage and lifespan. By adding poly(propylene glycol) (PPG) in the electrolyte, detrimental side reactions induced by water reduction and Zn dendrite growth can be successfully suppressed, leading to a highly reversible aqueous hybrid ion battery with high specific capacities and long cycle life.

Summary: Lightdegradable polymers have great potential in various applications, such as optically recyclable materials, responsive coatings and adhesives, and controlled drug delivery. Researchers have synthesized polyurethanes that can degrade under visible light irradiation (& LE;450 nm) from commercial LED (3-15 W) light sources. The photolysis occurs in an aqueous environment through the photocleavage of an acridine moiety incorporated in the polymer chains. Analysis of the quantum yield shows highly efficient photoreactivity, especially at 440 nm activation, which is red-shifted compared to the UV-vis absorbance of the chromophore. The potential of this chemical system in biomaterials is demonstrated by fabricating an in situ forming hydrogel that can be degraded by visible light.

Summary: Inspired by pitcher plant, a porous foam-like lubricant-infused surface (F-LIS) was synthesized. The fog harvesting efficiency of the surface can reach 2761.2 mg cm-2 h-1. F-LIS demonstrates excellent mechanical durability and chemical stability as a result of the micro/nano structure and the strong intermolecular force between PFPE as lubricant and the modifier layer, PFDT. This work offers a simple and effective approach for fabricating lubricant-infused surfaces with distinguished fog harvesting capability, providing a reference for relieving the crisis of freshwater resource scarcity.

Summary: Frequent oil spills have a significant impact on ecological balance. Traditional superhydrophobic materials are limited to organic solvent separation and lack the ability to undergo thermal conversion. Photothermal materials, utilizing solar energy as a constant power source, have emerged as promising, environmentally friendly, and cost-effective solutions. This study presents the self-assembly of titanium nitride/polydopamine nanoparticles on polyurethane sponges and subsequent coating with polydimethylsiloxane. The material demonstrates excellent photothermal conversion efficiency, stability, and adhesion, making it suitable for continuous separation of crude oil/seawater in oceanic environments.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
