“…Results showed that the protein-corona inhibits the cellular uptake of ferroferric oxide NPs, the progress may result from the surface energy change of nanoparticles with protein-corona. Although nanomaterials have been widely investigated in last two decades, [30][31][32][33][34][35][36][37][38][39][40][41][42] the findings in our work will contribute to the nanotoxicity evaluation of ferroferric oxide NPs and help to perfect their biomedical applications. …”

It is now well accepted that nanoparticles (NPs) will be coated with proteins in a biological environment, and there is some consensus that the protein corona can significantly influence the particlecell interactions. Ferroferric oxide NPs have been an attractive platform for biomedical applications due to their unique magnetic properties and good biocompatibility. In this work, ferroferric oxide NPs were incubated with MDA-MB-231 cells in serum free medium (SF) or the one with 10% fetal bovine serum (cDMEM) to evaluate the influence of protein-corona on NPs when they interacted with cells. Cellular internalizing of NPs was observed by flow cytometry and confocal microscopy. The analysis of flow cytometry showed that a larger quantity of nanoparticles aggregated in cytoplasma in SF than in cDMEM after 6 hours incubation and this result was confirmed by confocal observation. In concluded, the presence of a protein-corona will decrease the cellular uptake efficiency of ferroferric oxide NPs. The data of protein-corona influence for nanoparticles cell-internalization will contribute to the nanotoxicity evaluation of ferroferric oxide NPs and help to improve their biomedical applications.

Highly dispersed MoO 3 on SiMCM-41 was applied to the dehydration of 2-butanol. MoO 3 /MCM-41 catalysts were prepared using a modified atomic layer deposition method. The structural characteristics of MoO 3 supported on SiMCM-41 were examined by inductively coupled plasma spectrometry, nitrogen adsorption, X-ray photoelectron spectroscopy, and X-ray diffraction. The textural characteristics of SiMCM-41 were retained after loading with MoO 3 . Ammonia temperature-programmed desorption and Fourier transformation infrared spectroscopy of adsorbed pyridine showed that Lewis acid sites were formed on the MoO 3 /MCM-41 catalysts. Among the MoO 3 /MCM-41 catalysts, the MoO 3 (16.4 wt %)/MCM-41 catalyst showed the highest catalytic activity for butene synthesis from 2-butanol dehydration due to the largest number of acid sites.

“…This reaction transforms linear alkanes into branched ones, which have higher octane numbers and therefore utilize light gasoline fraction of atmosphere refining [1][2][3][4][5][6]. Usually, branched paraffins are obtained by isomerization over bifunctional catalysts, which have Broensted and Lewis acidic and hydrogenating-dehydrogenating active sites [7][8][9][10][11]. Mordenite zeolite and alumina are used in the role of acidic support, whereas hydrogenating-dehydrogeneting sites are usually formed by platinum group metals.…”
