Summary: The research focused on the arrangement of polyelectrolytes in multilayered PMC capsules and found that the dissociation of different layers is equal regardless of the presence or absence of the shell. The study also revealed that FITC-labeled polyallylamine migrates to the periphery of the microcapsule due to increased osmotic pressure caused by the flow of ions. This effect is enhanced by the lower charge density and less interaction of FITC-polyallylamine with polystyrene sulfonate in the microcapsule structure.

Summary: This paper studied the entropy-driven formation of binary superlattices assembled from polymer-tethered nanorods and nanospheres. The results indicated that the conformational entropy of the polymer chains and the mixing entropy of the nanorods and nanospheres are two parameters that determine the formation of binary superlattices.

Summary: Early diagnosis and treatment of pathogenic bacteria are crucial in preventing further infection. Photothermal therapy (PTT) is a promising method for sterilization, with minimal invasiveness and high efficiency. In this study, Ti3C2-Au nanomaterials were prepared with modulated absorption characteristics to achieve high photothermal conversion efficiency and sensitive label-free SERS bacterial detection. The results showed that Ti3C2-Au had better SERS performance than Au, allowing for direct and sensitive detection of E. coli and S. aureus. Ti3C2-Au NBPs exhibited enhanced photothermal conversion efficiency and broad-spectrum antibacterial properties.

Summary: The visible-light-active bismuth sulfide@reduced graphene oxide nanocomposite photoanode exhibited high photocurrent density and applied bias photon-to-current efficiency in PEC water splitting, attributed to the effective visible-light absorption of bismuth sulfide and good electron-transfer properties of highly conductive reduced graphene oxide nanosheets, facilitating charge separation and transportation while inhibiting charge recombination.

Summary: A hybrid nanoplatform consisting of an AuNR core surrounded by a polydopamine (PDA) shell was synthesized and its photocatalytic behavior was studied. The nanocomposites exhibited better photocatalytic performance compared to bare AuNRs and bare PDA nanoparticles. The thickness of the PDA shell affected the plasmon response of the composite. Photodegradation kinetics, time-resolved spectroscopy, and finite-element-method simulations showed that the plasmons of AuNRs, coupled with the low thermal conductivity of PDA, provided slow thermalization while enhancing charge carrier transfer.

Summary: Hard template-directed growth methods are effective for synthesizing Ag nanostructures with precise size control, while soft template methods are flexible for synthesizing Ag nanostructures with various morphologies. However, the strong confinement effect of the hard template limits the diversity of Ag nanostructures and neglects the role of the soft template.

Summary: In this study, ZnO nanorods were successfully grown on glass substrate using the hydrothermal method, and the effect of zinc precursor salt concentration on nanorod properties was investigated. XRD, SEM, UV-visible optical transmittance and PL were used to analyze the structure and properties of the nanorods. The results showed that increasing the salt solution concentration led to the formation of ZnO nanorods with larger diameter and denser array.
