Wire explosion technique has been widely studied in recent years to produce nanoparticles of different materials due to the enormous outstanding characteristics of nanomaterials as well as the advantages of wire explosion technique1. In the wire explosion process for preparation of nanoparticles, the wire firstly melts, vaporizes and then generates a mixture of metal vapor and liquid droplets. The...
Microsecond explosion of metallic wires has drawn attention of many researchers due to its complicated physical process and various applications, such as production of metal nanoparticles1. When a high density pulsed current passes through a thin wire, it quickly melts, vaporizes and ionizes. The medium pressure and charging voltage have significant effect on the development of the generated plasma2...
Ag-Cu nanoalloy has been synthesized directly in solution. The composition, morphology and structure of the Ag-Cu nanoalloys were characterized by XRD, TEM, EDS and SEM. The morphology of Ag-Cu nanoalloys appears small, uniform, and spherical. The size distribution mainly focuses on 80nm~90nm. An average composition is Ag48.9Cu51.1, which is within experimental error of the nominal 1:1 stoichiometry...
During curative cancer surgery, magnetic retraction could offer advantages over retraction by graspers because of reduced tissue trauma and with the potential for noncontact retraction. To realize magnetic retraction, magnetic fluid was injected into harvested porcine stomachs and an external permanent magnet was used to retract the ferromagnetized tissue. The magnetic forces of four ferrofluids were...
