Amylose and amylopectin were pyrolyzed at 400°C and then oxidized with HNO 3 and H 2 SO 4 to modify its surface chemical properties. The pore structures and surface chemical properties of pyrolyzed carbons before and after oxidation were characterized and compared by nitrogen adsorption isotherms, thermogravimetric analysis, FT-IR spectra and SEM images. The results indicated...
Polycrystalline TiO 2 thin films were formed on Pt(111)/Ti/SiO 2 /Si by thermal oxidation of Ti films with temperatures ranging from 600°C to 800°C. Results of Raman spectra testing indicate that the structure of the oxidized TiO 2 films is rutile phase. The resistance switching behaviors (RSB) have been confirmed in Pt/TiO 2 /Pt structures. A stable RSB with a narrow...
