This communication describes a single-step electrospraying technique that generates core-shell microspheres (CSMs) with encapsulated protein as the core and an amphiphilic biodegradable polymer as the shell. The protein release profiles of the electrosprayed CSMs showed steady release kinetics over 3 weeks without a significant initial burst.

Abstract A fast, simple, and energy-saving microwave-assisted approach was successfully developed to prepare carbon microspheres. The microspheres with a uniform particle size good dispersity were prepared using glucose as the raw material HCl dehydrating agent at low temperature (90°C) in an open system assistance of microwave heating. characterized by elemental analysis, XRD, SEM, FTIR, TG, R...

In this paper, we describe the synthesis and characterization of a luminomagnetic microspheres with core-shell structures (denoted as Fe3O4@ SiO2 @SiO2-Tb(PABA)3). The luminomagnetic microspheres were characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometer (VSM),...

TiO(2) microspheres constructed by well-crystallized faceted nanorods with high aspect ratios expose 100% photocatalytic reactive {111} facets on the spherical surface. The microspheres demonstrated excellent photocatalytic antibacterial activity towards Staphylococcus aureus due to effective suppression of photoinduced electron-hole pair recombination and active TiO(2)@˙OH core-shell structure.

We herein demonstrated an approach to control the spatial distribution of components in hybrid microspheres. Hybrid core-shell structured microspheres (CSMs) prepared through co-assembly were used as starting materials, which are comprised of anthracene-ended hyperbranched poly(ether amine) (AN-hPEA) in the shell and crystallized anthracene containing polyhedral oligomer silsesquioxane (AN-POSS...

New Cu2O@TiO2 core-shell microspheres were successfully prepared for the first time in this paper. The XRD, N2 adsorption-desorption, SEM, TEM, EDX and XPS characterizations utilized to investigate physical chemical properties. liquid phase oxidation of naphthalene was also carried out test their catalytic performance. characterization results indicating that Cu2O firstly formed by hydrothermal...
