Local atomic structure of lanthanide complexes in cubic ordered mesoporous silica
(Elsevier B.V., 2013-05-25)
The aim of this work was to analyze the local atomic environment around lanthanide atoms anchored inside silica matrices by means of X-ray absorption spectroscopy (XAS). Europium and cerium complexes were incorporated in ...
Exploiting mesoporous silica nanoparticles as versatile drug carriers for several routes of administration
(2021-01-01)
The exploitation of mesoporous silica nanoparticles (MSNs) as drug delivery systems has grown exponentially due to their remarkable tunable properties, such as high surface area, chemical and physical stability, high loading ...
About the thermal stability and pore elimination in the ordered hexagonal mesoporous silica SBA-15
(Elsevier B.V., 2014-05-15)
Ordered hexagonal mesoporous silica was prepared using Pluronic P123 template and removal of the polymer by washing in ethanol. The thermal stability and the pore elimination was studied under heat treatment by a fixed ...
Mesoporous silica-titania composed materials
(Academic Press Inc Elsevier Science, 2006-08)
Titania mesosized particles were obtained by TiCl4 hydrolysis in Aerosol OT/water/n-hexane microemulsion. These particles were incorporated in surfactant templated silica mesoporous materials of MCM-41 and MCM-50 structures. ...

Rapid pore expansion of mesoporous silica-based materials using microwave irradiation and pore swelling agents
(Elsevier, 2021-12)
In the present work we analyze the use of microwave radiation in the presence of pore swelling agents as a post-synthesis treatment for expanding the pore size of non-calcined SiO2-based mesoporous materials. In comparison ...
