چکیده
The double-layered microencapsulation technology has been used in many fields. In this study, the microencapsulated anthocyanin of Passiflora edulis shells (APESs) was prepared via complex coacervation using gelatin and gum Arabic as first wall materials (single-layered microcapsules (SMs)) containing nano-SiO2 second material (double-layered (DMs)/nano-SiO2) to enhance stability core material. Properties were analyzed on basis EE, morphology, scanning electron microscopy (SEM), droplet size, moisture content, differential calorimetry (DSC). results showed that EE values SMs, DMs, DMs/nano-SiO2 96.12%, 97.24%, 97.85%, respectively. had lowest content (2.17%). average size (34.93 μm) higher than those SMs DMs. DSC indicated melting temperature 73.61°C 45.33°C SEM demonstrated smoothest surface compared with other two kinds microcapsules. storage APESs their improved by adding into These silica nanoparticles contribute

Self-assembly preparation of SiO2@Ni-Al layered double hydroxide composites and their enhanced electrorheological characteristics
The core-shell structured SiO2@Ni-Al layered double hydroxide (LDH) composites were prepared via self-assembly of Ni-Al LDH on the surface of SiO2 spheres. Only coating a layer of ultrathin Ni-Al LDH sheet, the resulting SiO2@Ni-Al LDH composites exhibit significantly enhanced electrorheological (ER) characteristics compared to conventional bare SiO2 spheres. The monodispersed SiO2 spheres with...

Preparation and Characterization of Double Shell Fe3O4 Cluster@Nonporous SiO2@Mesoporous SiO2 Nanocomposite Spheres and Investigation of their In Vitro Biocompatibility
Background: Multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. A rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles. Objectives: Herein, we report on a simple approach for the synthesis of m...
