The present study deals with the synthesis andfunctionalization of mesoporous silica nanoparticles as drug delivery platforms. SBA-15 nanorods with high surface area (1010 m2g-1) were functionalized by post grafting method using 3-mercaptopropyl trimethoxysilane (MPTS). The parent and thiol-functionalized SBA-15 nanorods were used as nanocarriers for an anticancer drug (gemcitabine). The charac...

Highly active rhodium catalysts have been prepared by immobilization of an ionic liquid film on carbon nanotubes functionalized with imidazolium-based ionic moieties.

The chemical surface of Santa Barbara Amorphous-15 (SBA-15) was functionalized with polyaniline (SBA-15/PA) and prepared using aniline ammonium persulfate as the modifying agent oxidant. samples were characterized by N2 physical adsorption at 77 K. SBA-15′s area 654.5 m2 g−1, changing to 254.6 g−1. total acidity basicity determined a modified Boehm’s method, point zero charge pH (pHpzc) determi...

Palladium nanoparticles have been deposited onto imidazolium bromide-functionalized ionic MWCNTs through hydrogen reduction of Na2PdCl4 in water without aid of surfactants under extremely mild conditions, and combined with an ionic liquid to create a new recyclable ionic liquid-based catalytic system allowing up to 50 times recycling.

This work reports the electrochemical detection of bisphenol A (BPA) using a novel and sensitive sensor based on Cu functionalized SBA-15 like periodic mesoporous organosilica-ionic liquid composite modified glassy carbon electrode ([email protected]/IL/GCE). The structural morphology [email protected] is characterized by X-ray powder diffraction (XRD), energy dispersive analysis (EDX), Fourier...

INTRODUCTION Confinement of biomolecules in structured nanoporous materials offers several desirable features ranging from chemical and thermal stability, to resistance to degradation from the external environment. A new generation of mesoporous materials presents exciting new possibilities for the formulation and controlled release of biological agents. Such materials address niche application...

For the first time an ordered mesoporous silica (Fe-Al-SBA-15) with catalytically active isolated Fe surface species for the hydroxylation of benzene with nitrous oxide is prepared by introduction of Fe3+ in the synthesis gel of Al-SBA-15.

The extraction behavior of neodymium and other rare earths from nitric acid media by the functionalized ionic liquid trioctylmethylammonium dioctyl diglycolamate, [A336][DGA], was investigated. The nonfluorinated ionic liquid trioctylmethylammonium nitrate, [A336][NO3], was used as diluent. The extraction behavior of neodymium(III) in this ionic liquid solution was carried out as a function of ...
