In article number 2004867, Yiqin Shi, Guqiao Ding and co-workers demonstrate the superior sonosensitization effect of N-doped graphene quantum dots, which is believed to be 3–5 times higher than that traditional sonosensitizers. More importantly, pyrrole N pyridine are form catalytic centers in sonochemical processing dots. This knowledge important from perspective understanding structure-depen...

in this paper, undopedzno and co-znonano structureswith different molar ratio of cobalt have been synthesized by the sonochemical method. structure have been characterized by fourier transform (ftir) and uv–vis spectroscopy,scanning electron microscopy (sem), energy dispersive analytical x-ray (edax), and x-ray diffraction (xrd) methods. moreover, the direct band gap has been calculated by tauc...
