A novel approach to produce monodisperse hollow pure ...

In conclusion, the monodisperse hollow pure silica spheres were successfully prepared by employing a simple approach without the use of template. The phenyl groups of silica were removed by calcination and pure silica spheres with well-preserved spherical structure and hollow core were obtained.

Facile Preparation of Highly Monodisperse Small Silica ...

Highly monodisperse spherical silica nanoparticles with diameters ranging from ca. 15 to 200 nm were prepared using an environmentally friendly water-based synthesis. The size of the spheres can be precisely controlled by using a facile regrowth procedure in the same reaction media. Furthermore, these monodisperse silica spheres can be successfully used as seeds in the well-established Stöber ...

Monodisperse Microspheres, Monodisperse Particles Supplier ...

Monodisperse microspheres are microbeads with narrow particle size distribution. We use CV, coefficient of variation to evaluate the uniformity of beads. The lower of CV, the narrower of the particle size distribution. There are various materials can be synthesized as monodisperse microspheres such as polymer, silica and TiO2.

A Novel Method for the Fabrication of Monodisperse Hollow ...

In this paper, we report a novel method for the fabrication of small monodisperse hollow silica spheres. In this approach, when silica shells were coated on polystyrene particles by the sol−gel method, the polystyrene cores were dissolved subsequently, even synchronously, in the same medium to form monodisperse hollow spheres. Neither additional dissolution nor a calcination process was ...
