Nanopowders produced by electrical explosion of wires
Electrical explosion of wires (EEW) is a method for production of nanopowders. Depending on type of chemical composition of working ambient in the discharge chamber nanopowders of carbides can be produced (EEW in hydrocarbons) or nanopowders of oxides (EEW in oxygen contained medium). Phase compositions of nanopowders prepared by electrical explosion of tungsten and aluminium wires in liquid an...
متن کاملInvestigation of fusion yield from exploding deuterium-cluster plasmas produced by 100-TW laser pulses
When clusters of deuterium are irradiated with an intense, ultrafast laser pulse, the clusters explode, generating ions with kinetic energies high enough to produce nuclear-fusion events. Here we present experimental measurements of the dependence of the fusion yield of an exploding deuterium-cluster plasma on pulse energy up to the 10-J level for incident pulse durations of 100 fs and 1 ps. Th...
متن کاملResistance Changes Caused by Vaporization Waves in Exploding Wires Ddc
The marked Increase In electrical resistance occurring at temperatures above melting can be explained by assuming a vaporizaf on, expansion wave proceeding radially inward from the wire surface. This wave reduces the conducting cross section of the wire, thereby increasing the resistance. For wires well matched to the circuit the resistance rise occurs when the condenser voltage is practically ...
متن کاملSpark plasma sintering of alumina nanopowders produced by electrical explosion of wires
Alumina nanopowders produced by electrical explosion of wires were sintered using the spark plasma sintering technique. The results of XRD analysis show that the main phase in the compacted nanopowders is α-Al2O3. According to the SEM observations, the sintered alumina nanopowder consists of micron-sized faceted grains and nano-sized necked grains. The increase in sintering temperature resulted...
متن کاملStructure of an exploding laser-produced plasma.
We describe the first-ever volumetric, time-resolved measurements performed with a moving probe within an expanding dense plasma, embedded in a background magnetized plasma. High-resolution probe measurements of the magnetic field and floating potential in multiple 2D cut planes combined with a 1 Hz laser system reveal complex three-dimensional current systems within the expanding plasma. Stati...
