We explore the possibility of coating semiconductor nanowires with metal (Ag) to reduce the size of nanowire lasers operating at photon energies around 0.8–2 eV. Our results show that the material gain of a typical III-V semiconductor in nanowire may be sufficient to compensate Joule losses of such metal as Ag. The most promising mode to achieve lasing seem to be TM01 near its cutoff. To calcul...
Abstract Hot-wire laser welding is additive manufacturing (AM) technique that allows for the direct creation of complicated objects by melting layers wire. This process characterized use hot-wire process, unification with (LW) in AM process. The empirical investigation employing a on titanium alloy (grade 2) workpiece presented this research. There are three parameters namely wire current, spee...
Thick carbon nanofiber (CNF) films were uniformly grown on metal wires with the assistance of pre-deposited NiO nanowalls. The as-prepared wire-shaped composites that integrate the capacitance of CNFs and Ni particles were directly used as electrodes to construct high capacitive fiber supercapacitors for micro-power supplies.
In this work, the effect of a filler wire feed rate was studied with special attention to proportion porosity volume in weld metal, microstructure, and mechanical properties. Butt laser joints were created using Nd:YAG laser. Weld produced AZ31 diameter 1.2 mm. Decreasing led an increase metal. Therefore, is more likely occur welding without use wire. Clear segregation aluminium, manganese, zin...
