, 60CoΥ-ray irradiation, Fe3O4 magnetic nano-particles were successfully synthesized at room temperature under ambient pressure. The structure, morphology and magnetic properties of these nano-particles were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM) and vibrating sample magnetometer (VSM), respectively. The radiation formation mechanism was also discussed......
Annealing effect and irradiation properties of HFCVD diamond films REN Ling(任 玲)1, WANG Lin-jun(王林军)1, SU Qing-feng(苏青峰)1, LIU Jian-min(刘健敏)1, XU Run(徐 闰)1, PENG Hong-yan(彭鸿雁)2, SHI...; radiation 1 Introduction Diamond used as semiconductor material exhibits many outstanding features such as chemical inertness, irradiation hardness and wide band gap. Other desirable properties of diamond......
-angle annular dark-field transmission electron microscope(HAADF-TEM) image prove that core–shell structure of Au@Pd nanoparticles forms.TEM results indicate that Au@Pd nanoparticles(5.2 nm)are well-dispersed on the surface of f uv-MWCNTs. X-ray photoelectron spectroscopy(XPS) reveals that ultraviolet irradiation can promote the interaction between Au@Pd nanoparticles and the functional groups......
