The first aim of the present investigation was to prepare solid dispersions to improve the dissolution properties of oxcarbazepine and quetiapine using PEG 6000 as a carrier with the help of two methods of preparations viz. spray drying and modified solvent method, and to compare the two methods. The second objective was to apply the modified solvent method for preparation of sustained re...
In the present study, in-situ synthesis of carbon nanotube/hydroxyapatite nano composite powder with stable homogeneous dispersions of carbon nanotubes (CNTs) was carried out using surfactant as dispersing agent. By applying sol-gel method, dispersion in the hydroxyapatite matrix and its effects on the microstructure were investigated. The chemical and phase composition, structure and morpholo...
Stable homogeneous dispersions of carbon nanotubes (CNTs) were prepared using ethanol as dispersing agent. Then, using sol-gel method, dispersion in the hydroxyapatite matrix and its effects on the microstructure were investigated. The phase composition, chemical structure and morphological and size analyses were performed using XRD, FT-IR, SEM, TEM/SAED/EDX and Raman spectroscopy. The influenc...
