Mesoporous silicon is a biocompatible, biodegradable material that is receiving increased attention for pharmaceutical applications due to its extensive specific surface. This feature enables to load a variety of drugs in mesoporous silicon devices by simple adsorption-based procedures. In this work, we have addressed the fabrication and characterization of two new mesoporous silicon devices pr...

Recently mesoporous materials have drawn great attention in fuel cell related applications, such as preparation of polymer electrolyte membranes and catalysts, hydrogen storage and purification. In this mini-review, we focus on recent developments in mesoporous electrocatalysts for polymer electrolyte membrane fuel cells, including metallic and metal-free catalysts for use as either anode or ca...

The aim of this article is to review current knowledge related to the synthesis and characterization of sol gel-derived SBA-16 mesoporous silicas, as well as a review of the state of the art in this issue, to take stock of knowledge about current and future applications. The ease of the method of preparation, the orderly structure, size and shape of their pores and control, all these achievable...

Ordered mesoporous carbon/iron oxide composites were prepared by cooperative self-assembly of poly(tbutyl acrylate)-block-polyacrylonitrile (PtBA-b-PAN), which contains both a carbon precursor block and a porogen block, and phenol-functionalized iron oxide nanoparticles (NPs). Because of the selective hydrogen bonding between the phenol-functionalized iron oxide NPs and PAN, the NPs were prefer...

a novel sulfur nanocomposite was fabricated based on graphitic mesoporous carbon.the graphitic mesoporous carbon was synthesized using sucrose as carbon precursor, nano caco3 as hard template and nickel nitrate as graphitization catalyst. the structural properties of the prepared material were characterized using powder x-ray diffraction (xrd), n2-adsorption/desorption and scanning electron mic...

In  this  study,  amino  functional  groups  were  chemically  bonded  to  the  surface  of  newly synthesized  KIT-6  mesoporous  magnetite  nanoparticles  (MMNPs)  by  post-toluene  reflux synthesis method.  This method  treats  calcined mesoporous  nanoparticles with  the  functional organosilanes.  Physical  and  chemical  structures  of  the  synthesized  mesoporous  magnetite nanoparticle...

We demonstrate a CTAB-templated approach towards direct coating of mesoporous titania on gold nanorods in aqueous solutions. The formation of the mesoporous shell is found to be closely correlated with CTAB concentration and the amount of the titania precursor. This approach can be readily extended to form mesoporous titania shells on other CTAB-capped nanoparticles.

the goal of this research is to determine the feasibility of loading rifampin into mesoporous silica nanoparticles. rifampin was selected as a model lipophilic molecule since it is a well-documented and much used anti tuberculosis drug. the mesoporous silica nanoparticles were prepared by using tetraethyl ortho silicate and cetyltrimethyl ammonium bromide (as surfactant); the prepared nanoparti...

We have established a facile and generalizable "silica-assisted" synthesis for diverse carbon spheres-a category that covers mesoporous carbon nanospheres, hollow mesoporous carbon nanospheres, and yolk-shell mesoporous carbon nanospheres-by using phenolic resols as a polymer precursor, silicate oligomers as an inorganic precursor, and hexadecyl trimethylammoniumchloride as a template. The part...
