SiO(2)/poly(ethyleneglycol dimethacrylate) (PEGDMA) rattle-type microspheres loaded with tiny sized gold nanoparticles (~2 nm) were prepared through a facile and novel method. Catalyzed reduction of 4-nitrophenol with NaBH(4) demonstrated that this rattle-type microsphere possessed high catalytic efficiency.

Unlabelled: A chemical template strategy was put forward to synthesize monodisperse rattle-type magnetic carbon (FeO@C) hollow microspheres. During the synthesis procedure, monodisperse FeO microspheres were used as chemical template, which released Fe ions in acidic solution and initiated the in-situ polymerization of pyrrole into polypyrrole (PPy) shell. With the continual acidic etching of FeO microspheres, rattle-type FeO@PPy microspheres were generated with the cavity appearing between the PPy shell and left FeO core, which were then transformed into FeO@C hollow microspheres through calcination in nitrogen atmosphere.

Template-etching strategy was put forward to synthesize rattle-type magnetic silica (FeO@SiO) hollow microspheres in a controlled way. During the experiment, monodisperse FeO microspheres were fabricated as physical template to generate uniform FeO@SiO with controlled shell thicknesses through sol-gel method, and the subsequent FeO template etching process created variable space between FeO core and SiO shell, and the final calcination process transformed rattle-type FeO@SiO hollow microspheres into corresponding FeO@SiO product in hydrogen/nitrogen atmosphere. Compared with traditional physical template, here template-etching synthesis of rattle-type hollow microspheres saved the insertion of middle shells and their removal, which simplified the synthesis process with controllable core size and shell thickness.

Functional polymer micro- and nanoparticles with novel morphology are of great importance because of their wide range of applications in complex biological systems and nanotechnology. Due to the outstanding advantage of the absence of any surfactant, precipitation polymerization as a heterogeneous polymerization technique has been developed to prepare various uniform and clean polymer particles, such as microspheres, nanoparticles, core-shell particles, core-double shell particles, single-shell hollow particles, double-shell hollow particles, and rattle-type hollow nanostructures. In this review, a general introduction into the categories of precipitation polymerization and their mechanisms is presented.

Magnetically driven separation technology has received considerable attention in recent decade for its great potential application. In this work, hierarchically structured magnetite-carbonaceous microspheres (Fe(3)O(4)-C MSs) have been synthesized for the adsorption of heavy metal ions from aqueous solution. Each sphere contains numerous unique rattle-type structured magnetic particles, realizing the integration of rattle-type building unit into microspheres.
