Opis:: A novel technique, with which in situ $TiB_2$ particles and serpentine channels are introduced to prepare wrought aluminum alloy with higher strength, has been successfully applied to produce semi-solid 7075 alloy slurry. The effects of in situ $TiB_2$ particles and serpentine channels on the microstructure of the 7075 alloy including the grain growth behavior in the semi-solid state of the 7075 alloy were investigated. The experimental results showed that the in situ $TiB_2$ particles and serpentine channels are beneficial to increase the number of solidification nuclei and to promote uniform distribution of α-Al nuclei. As a result, the semi-solid 7075 alloy slurry with globular-like grains has been successfully produced.

Opis:: The basic building block of every photonic circuit is a waveguide. In this paper we investigate the most popular silicon waveguide structures in the form of a silicon-on-insulator rib waveguide. We also analyse two structures that can find applications in mid- and long-wave infrared regions: free-standing and hollow core omnidirectional waveguides.

Opis:: Charging operations of a compact Tesla transformer were experimentally investigated, in single-shot and rep-rate (50 pps for 1 s) modes, respectively. The charging limitations were also explored. The experimental results were compared and analyzed. The maximum secondary charging voltages of the Tesla transformer were measured to be 380 kV and 300 kV in single-shot and rep-rate modes, respectively. The RMS pulse-to-pulse instability of the secondary charging voltage is generally less than 10% but increases with the increasing initial voltage across the primary capacitor. Since the secondary capacitor of the Tesla transformer is a pulse forming line (PFL), continued operation is possible if there is breakdown in the PFL. Furthermore, operation can even be continued under occasional breakdown for some pulses, without the effects on the operations of subsequent pulses.
