Synthesis of mesoporous silica
2022Mesoporous materials are materials that have pore diameter values between 2 and 50 nm according to the IUPAC nomenclature. Due to their unique properties, they have gained a considerable amount of attention within the fields of catalysis, adsorption and ion exchange. Thanks to great specific surface area (SSA) of mesoporous materials, they also play an

Inclusion and Release of Fenbufen in Mesoporous Silica
Journal of Pharmaceutical Sciences, 2010This work reports the immobilization of Fenbufen, a nonsteroidal anti-inflammatory drug, into two different hexagonal mesoporous silicas (MCM-41) which exhibit some differences in terms of morphology and pore size, and their behavior as systems for sustained release at pH 7.5.

Mesoporous silica spheres from colloids
Journal of Colloid and Interface Science, 2007A novel method has been developed to synthesize mesoporous silica spheres using commercial silica colloids (SNOWTEX) as precursors and electrolytes (ammonium nitrate and sodium chloride) as destabilizers. Crosslinked polyacrylamide hydrogel was used as a temporary barrier to obtain dispersible spherical mesoporous silica particles.

Superstructures of mesoporous silicas
Current Opinion in Colloid & Interface Science, 1998During the past year, the major breakthroughs in the field of ordered mesoporous silicas have been the development of various techniques to control the morphologies of the materials on the macroscale and to align the pores of the materials on the microscale. The quality of the materials has also greatly improved, and the ability to control pore size in

Ultrabright Fluorescent Mesoporous Silica Nanoparticles
Small, 2010AbstractThe first successful approach to synthesizing ultrabright fluorescent mesoporous silica nanoparticles is reported. Fluorescent dye is physically entrapped inside nanochannels of a silica matrix created during templated sol–gel self‐assembly. The problem of dye leakage from open channels is solved by incorporation of hydrophobic groups in the ...

Characterization of vanadium-containing mesoporous silicas
Microporous Materials, 1995Vanadium-containing mesoporous silicas (V-MS) have been synthesized with primary amines as templates and characterized using spectroscopic techniques. Vanadium could be incorporated into the silica framework up to a content of about 2.5 wt.-% without formation of significant amounts of vanadium oxide after calcination.
