Summary: The hierarchical micro/nanostructured composites containing iron and/or its (hydr)oxides exhibit high rate and capacity of arsenic adsorption. In this study, low toxicity AlOOH/AlFe hierarchical micro/nanostructures were used to remove arsenic, showing a high adsorption capacity of more than 200 mg/g As(V) from its aqueous solution. The non-toxic nanostructures offer new possibilities for treating water contaminated by arsenic pollution.

Summary: Inorganic chiral nanoparticles, particularly gold chiral nanostructures, are receiving increasing attention for their unique optical properties and potential biological applications. This study successfully synthesized gold nanostructures with opposite circular dichroism signals depending on the amino acid enantiomer used during synthesis. The gold nanostructures were further decorated with penicillamine, and it was shown that both penicillamine enantiomers can be successfully bonded with both the enantiomers of the gold nanostructures without affecting their chirality. This research provides important insights into the control of chirality and surface properties in chiral nano-systems.

Summary: Yolk-shell structures are widely used in catalysis and energy storage. In this study, Mn2+ doped hierarchical CuS yolk-shell microspheres were synthesized and the influence of reaction time on their structure and morphology was investigated. A rational phenomenological approach was proposed to describe the formation mechanism of the yolk-shell structures, and it was found that Mn2+ doping improved the photoreduction performance.

Summary: Hierarchical flower-like Zn-2(OH)(3)VO3 assembled by 2D nanosheets were successfully synthesized using a one-step hydrothermal approach. The material exhibited highly uniform morphology and diameter, with an average thickness of 20 nm. Proper amount of NH3·H2O and adequate reaction time were found to be critical for obtaining high crystallinity in the hierarchical microflowers.

Summary: This study successfully achieved the coordination polymerization of diphenylphosphinostyrene and its copolymerization with styrene, resulting in a new series of phosphine functionalized syndiotactic polystyrene with excellent thermal stability and chemical resistance. The combination of triphenylphosphine and syndiotactic polystyrene allowed for the stable immobilization of metal nanoparticles to form highly robust nanocatalysts, showing high efficiency as a heterogeneous catalyst for the synthesis of quinoline derivatives.

Summary: Nucleic acids recognizing specific sequences are used as gating units in nano- or microcarriers to control and target drug release based on the presence of cellular biomarkers. Different types of aptamer-functionalized carriers, including inorganic materials, metal-organic framework nanoparticles, and soft materials, are discussed. Stimuli-responsive gated drug-loaded carriers are promising for targeted and selective drug release.
