Mesoporous silica nanoparticles (MSNs) impregnated with zero-valent Fe (Fe(0) @ MCM-41) represent an attractive nanocarrier system for drug delivery into tumor cells. The major goal of this work was to assess whether MSNs can penetrate the blood-brain barrier in a glioblastoma rat model. Synthesized MSNs nanomaterials were characterized by energy dispersive X-ray spectroscopy, measurements of X...

The syntheses of thermally stable chromium-incorporating hexagonal mesoporous aluminophosphate and cubic Cr-MCM-48 have been reported. Characterization of the catalysts was made using low angle XRD, N2 adsorption, UV-VISDRS, thermal analysis, ICP-AES and ESR. Mesoporous Cr-AlPO4 and Cr-MCM-48 catalysts have been found to be active for the vapour phase oxidation of toluene with molecular oxygen....

A series of mesoporous silica (MS) materials, including rod-like and spherical SBA-15, MCM-41, MCM-48, was successfully synthesized modified by silane coupling agent γ-aminopropyltriethoxysilane. The MS utilized as a microreactor for solution reversible addition–fragmentation transfer (RAFT) polymerization methyl methacrylate (MMA) using xanthate chain azodiisobutyronitrile an initiator. Notabl...

This study used porous nanomaterials MCM-41 and SBA-15, as well their modified species, to remove lead cadmium ions from water. We X-ray diffraction (XRD), a scanning electron microscope (SEM), the Brunauer–Emmett–Teller (BET), Fourier transform infrared (FT-IR) method investigate characteristics of nanomaterials. Additionally, atomic absorption spectroscopy (AAS) measured concentration ions. T...

Mesoporous templated MCM-48 silica was prepared using a C16 surfactant as template. The MCM-48 powders and thin films were characterized by different techniques. Two types of porous supports were used, namely macroporous α-alumina and silicon microsieves. The supported MCM-48 layers were applied as liquid permeable membranes in pressure-driven nanofiltration and electric field-mediated ion tran...

The use of solid adsorbents for CO2 capture is importance in the development technologies to remove this greenhouse gas. High surface area mesoporous materials are used encapsulate or functionalize amines that selectively CO2. MCM-41 class hexagonally ordered silicas have areas between 1000 and 1500 m2/g, which principle allows a significant degree when such as polyethyleneimine (PEI) encapsula...
