Effect of monomer dosing rate in the preparation of mesoporous polystyrene nanoparticles by semicontinuous heterophase polymerization.
The semicontinuous heterophase polymerization of styrene in the presence of cross-linking and porogen agents was carried out. Latexes with close to 20% solid content, which contained mesoporous nanoparticles with 28 nm in average diameters, up to 0.5 cm3/g in porosity and 6-8 nm in pore diameters were obtained. By varying the monomer dosing rate over the micellar solution, an unexpected direct ...
متن کاملRadar absorption of FeNi nanoparticles and FeNi@PANI nanocomposites prepared by in-situ polymerization
In this research, FeNi@PANI nanocomposites as the electromagnetic wave absorbers were prepared through two following steps. At first, FeNi alloy nanoparticles were synthesized by the one-pot polyol process, and then, in-situ polymerization method was used for the preparation of FeNi@PANI nanocomposite. The XRD pattern confirmed the formation of pure FeNi alloy with the FCC crystalline phase. Th...
متن کاملPrecipitated Calcium Carbonate Prepared by Batch and Semicontinuous Processes
A comparison of the physical-chemical properties of precipitated calcium carbonate (PCC), prepared by batch and semicontinuous processes, is presented. In both processes, PCC, was synthesized by carbonation of slaked lime. In the batch process the experiments were performed by varying the initial mass concentration and temperature, and the semicontinuous process was conducted by varying the ini...
متن کاملAnalgesic effect from Ibuprofen nanoparticles inhaled by male mice.
BACKGROUND Aerosol lung administration is a convenient way to deliver water-insoluble or poorly soluble drugs, provided that small-sized particles are generated. Here, for the outbred male mice, we show that the pulmonary administration of ibuprofen nanoparticles requires a dose that is three to five orders of magnitude less than that for the orally delivered particles at the same analgesic eff...
متن کاملEvaluation of Ibuprofen Release from Gelatin /Hydroxyapatite /Polylactic Acid Nanocomposites
Gelatin-hydroxyapatite-polylactic acid (PLA) nanocomposites were synthesized using five different formulations. The nanocomposites were loaded with ibuprofen and the amount of drug in the carriers was determined. X-ray diffraction (XRD) analysis was conducted before and after drug loading to ensure the presence of ibuprofen on the nanocomposites. Drug delivery was evaluated in phosphate buffere...
