Summary: A model system is established to achieve the formation of polymetallic nanocrystals (NCs) by diffusion of metal atoms between different NCs. The bond strength difference between metal atoms and the high surface-to-volume ratio of NCs play important roles in this process. Using the Au-Cu-Ag trimetallic system as an example, core-shell AuCu@Ag NCs are successfully formed by combining AgCu NCs with Au NCs.

Summary: This study presents a biosensor based on a core-shell nanostructure consisting of zinc oxide (ZnO) nanoparticles coated with gold (Au). The core-shell nanostructure serves as a support for the immobilization of tyrosinase on screen-printed carbon electrodes to measure dopamine. The results indicate that the biosensor has remarkable selectivity and accuracy for the detection of dopamine in real samples, with a relative error of 3.8%. Additionally, the biosensor has a limit of detection of 86 nmol L-1 and a dynamic range of 0.1 to 500 μmol L-1 for dopamine in real samples. Thus, the proposed miniaturized biosensor device shows promise for the monitoring of dopamine in real samples and could be used for disease diagnosis and prognosis.

Summary: In this study, a core-shell nanostructure composed of CoFe2O4 as the core and Prussian blue analog as the shell (CoFe2O4@PBA) was synthesized. The introduction of a photo-sensitive shell resulted in unexpected changes in saturation magnetization and coercivity of the hybrid material under illumination at 5 K. The photo-magnetic effect was attributed to the valence state transition of Fe ions in CoFe2O4 induced by the optical-excited electrons transfer from the CoFe PBA shell to the CoFe2O4 core.

Summary: Electrorheological (ER) fluid is an intelligent material consisting of polarized micro- and/or nanoparticles dispersed into insulating oil. Recently, the incorporation of molybdenum disulfide (MoS2), a popular 2D material, has offered a new approach to develop high-performance ER materials. However, MoS2 ER material suffers from low polarization strength and high electrical conductivity. To overcome these limitations, a two-step method is used to prepare PANI and MoS2 hybrid composite nanoparticles with unique morphology. The optimized ratio of PANI to MoS2 is found to be 4:1, resulting in excellent material performance with shear stresses reaching 150 Pa. Overall, this material demonstrates great potential as an electrorheological material.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.
