Interpenetrating polymer network (IPN) using chitosan and egg white cross linked with polyvinylpyrrolidone and polyethylene glycol was prepared by heat coagulation method. 5-Fluorouracil (5-FU) was chosen as a model drug which is effective for several cancer treatments. Eleven formulations were prepared by keeping chitosan concentration constant and varying the concentration of egg white and heating...
A facile solvothermal process is successfully developed to prepare F-center cubic Co 3 O 4 nanoflakes in ethylene–glycol–water solvent. Cobalt acetate [Co(Ac) 2 ⋅4H 2 O] is directly used as precursor and ethylene glycol performs a reducer and modifying agent in the system. The as obtained products were characterized by XRD, FT-IR, UV–Vis-DRS, SEM, EDAX, XPS and HR-TEM...
