A kind of mesoporous hybrid luminescence material was assembled through the ion exchange method between [Ln(DPA)3](3-) and ionic liquid functionalized SBA-15. [Ln(DPA)3](3-) was successfully anchored onto positive-charge modified SBA-15 by the strong electrostatic interaction. In [Ln(DPA)3](3-), Ln(3+) ions are in 9-fold coordination through six oxygen atoms of carboxyl groups and three nitroge...

We studied the effect of two types of mesoporous silica nanoparticles, MCM-41 and SBA-15, on mitochondrial O 2 consumption (respiration) in HL-60 (myeloid) cells, Jurkat (lymphoid) cells, and isolated mitochondria. SBA-15 inhibited cellular respiration at 25-500 microg/mL; the inhibition was concentration-dependent and time-dependent. The cellular ATP profile paralleled that of respiration. MCM...

The metaiodobenzylguanidine (MIBG) radiopharmaceutical, an analogue of norepinephrine, has been used to diagnose certain diseases in the cardiovascular system when radiolabeled with I. This radiopharmaceutical can also be used to treat tumors, such as neuroblastomas and pheochromocytomas, when radiolabeled with I. Its clinical use is often accompanied by a slow intravenous administration, where...

The catalytic activities of SBA-15 aluminosilica meso/macroporous monoliths (Si/Al = 72) and mesoporous powders (Si/Al = 70) have been investigated using batch Friedel–Crafts alkylation of single-ring aromatic compounds, including toluene, ethylbenzene, cumene, and styrene, with benzyl alcohol. The toluene alkylation activities of the meso/macroporous monolith catalysts were compared with nanop...

A protonated polyaniline-functionalized SBA-15 mesoporous silica nanomaterial (H(+)-PANI/SBA-15) with high surface area and ideal surface properties for the adsorption of anionic dyes is synthesized. Compared with the conventional emeraldine salt of polyaniline (H(+)-PANI), H(+)-PANI/SBA-15 has a significantly higher adsorption capacity for the anionic dye Orange G and is a more effective sorbe...
