We report on the interaction of pulmonary surfactant composed of phospholipids and proteins with nanometric alumina (Al2O3) in the context of lung exposure and nanotoxicity. We study the bulk properties of phospholipid/nanoparticle dispersions and determine the nature of their interactions. The clinical surfactant Curosurf, both native and extruded, and a protein-free surfactant are investigate...

• Surfactant-free Pt nanoparticles are obtained in alkaline ethylene glycol. In situ XANES and SAXS used to characterize the nanoparticle formation. The NaOH/Pt molar ratio influences kinetics of size. controlled synthesis surfactant-free (NPs) remains a challenge. To develop improved reproducible syntheses, deeper understanding formation mechanism NP is key. NPs particular important catalysts ...

the perovskite-type oxides strontium-substituted lanthanum nickelate (lsno) were prepared by a coprecipitation method in the present of octanoic acid as surfactant. the phase composition, morphology,lattice parameters and size of nanoparticles in these materials were characterized through fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microscopy (sem...
