Summary: The study introduces a novel anion conducting membrane using QTP-HCP-NS for the first time, demonstrating improved ion conductivity and mechanical properties compared to traditional membranes. The composite AEMs exhibit lower dimensional swelling, higher tensile strength, and significantly enhanced ion conductivity, thanks to the unique properties of QTP-HCP-NS. However, aggregation and interfacial defects at high loadings of QTP-HCP-NS may lead to a reduction in ion conduction and mechanical strength.

Summary: Fish scale-inspired underwater superoleophobic coatings can be achieved by creating hierarchical surface topography on water-compatible materials, but current methods do not allow for independent tuning of underwater superoleophobicity and oil adhesion. This study introduces a novel class of coatings, dually reactive multilayer coatings, which can independently tune these properties through orthogonal functionalization of reactive moieties at ambient conditions, leading to the development of superoleophobic sensors for real-time detection.

Summary: In this study, a method for synthesizing Pt NPs supported on 3D-NHPC (1.6 nm) through hyper-crosslinking mediated self-assembly and subsequent in situ pyrolysis reduction is reported. The prepared Pt@3D-NHPC (1.6 nm) catalysts possess a high surface area and hierarchically interconnected porous framework, providing more active sites and short transport paths for substrates. After H2O2 post-treatment, the superhydrophilicity of the Pt@3D-NHPC-H2O2 (1.6 nm) catalysts significantly increases, resulting in enhanced catalytic activity for cinnamaldehyde hydrogenation in aqueous solutions. Moreover, the nitrogen-doping and confinement of the porous framework contribute to the excellent stability and durability of the prepared Pt@3D-NHPC-H2O2 (1.6 nm) catalysts.

Summary: The synthesis of magnetically-separable cobalt catalyst embedded in hierarchically porous N-doped carbon nanospheres (Co@N-C) through in situ non-noble metal nitrate-promoted pyrolysis reduction has been successfully achieved. The catalyst displayed enhanced catalytic activity and stability in the hydrodeoxygenation of vanillin in aqueous solutions, owing to the presence of non-noble metal nanoparticles coated with a graphitic nitrogen-doped carbon layer. This approach can be extended to other non-noble metal nitrates, offering good recyclability, magnetically-separable ability, and general applicability.

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.
