The suggested mechanism of photocatalytic oxidization of EM over Cu2O@H2Ti3O7 nanocomposite under sunlight irradiation. Under the sunlight irradiation, photo-generated electrons (e?) of nanocomposite aggregated on nanotubes, and holes (h?) aggregated on Cu2O nanoparticles, which will reduce the bandgap energy and prolong the effective separation of photo-induced electron-hole pairs, enhance eventually the photocatalytic activity. It causes a large number of the hydroxy radical groups (·OH) generated on nanocomposite, which will effectively oxidize EM due to the synergistic effect between them to form heterojunction structure. Therefore, nanocomposite exhibits the excellent photocatalytic performance.

Panel (a) shows the 42?μm diameter spherical particle and the 405?nm laser beam as the respective dark and bright patches. Panel (b) shows that 40 milliseconds later the microsphere has traversed a distance roughly 10 times its size.

Because data storage and processing solutions are so central to modern technology, many research teams and companies are pursuing new types of computer memory. One of their major goals is to develop universal memory -- a storage medium that would combine the high speed of RAM with nonvolatility of a flash drive.
