Controlled release properties and final macroporosity of a pectin microspheres–calcium phosphate composite bone cement [PDF]

open access: yes, 2010
The use of calcium phosphate cements (CPC) is restricted by their lack of macroporosity and poor drug release properties. To overcome these two limitations, incorporating degradable polymer microparticles into CPC is an attractive option, as polymer ...

Colloidal stabilization via nanoparticle haloing

open access: yes, 2005
We present a detailed numerical study of effective interactions between micron-sized silica spheres, induced by highly charged zirconia nanoparticles. It is demonstrated that the effective interactions are consistent with a recently discovered mechanism ...

Entanglement of separate nitrogen-vacancy centers coupled to a whispering-gallery mode cavity

open access: yes, 2010
We present a quantum electrodynamical model involving nitrogen-vacancy centers coupled to a whispering-gallery mode cavity. Two schemes are considered to create W state and Bell state, respectively.

Facile preparation of CeO2 microspheres with high surface area by ultrasonic spray pyrolysis

open access: yesGreen Processing and Synthesis, 2018
CeCl3 solution was used as a precursor to prepare CeO2 microspheres by ultrasonic spray pyrolysis (USP). This is a green process that allows the transformation from CeCl3 to CeO2 without consuming any precipitant.

Inner structure of ZnO microspheres fabricated via laser ablation in superfluid helium

open access: yes, 2017
ZnO microspheres fabricated via laser ablation in superfluid helium were found to have bubble-like voids. Even a microsphere demonstrating clear whispering gallery mode resonances in the luminescence had voids.
