Chemical Characterization of Carbon Nanoparticles by Titration Method
Carbon nanoparticles (CNP) having below 10 nm in size. Firstly, in this study, starch nanoparticles were regenerated from sago starch by adding of starch solution into excess ethanol under controlled condition. After starch nanoparticles were obtained from available native sago starch. Then, it will...
