Through ball milling, mechanical energy is pumped into the Al 70 Co 15 Ni 15 matrix. A part of the energy is used in breaking the alloy particles, and another part is used in creating the defects such as dislocations and the distortion of the lattice.In other words, the mechanical energy provided by ball milling gives rise to the decrease in ...

Silver (Ag) was loaded on TiO 2 powders through mechanical ball milling. Ag-loading was accomplished by adding 4.6, 9.2, and 13.8 ml of AgNO 3 solution to the TiO 2 powders during the milling process. The resulting powder was characterized by XRD, XPS, SEM, and EDS. The photocatalytic activity of the silver-loaded powder was evaluated in terms ...
