The erosion rates for hemispherical electrodes, 2.5 em in diameter, made of graphite, copper-graphite, brass, two types of copper-tungsten, and three types of stainless steel have been examined in a spark gap filled with air or nitrogen at one atmosphere. The electrodes were subjected to 50,000 unipolar pulses (25 )ls, 4-25 kA, 5-30 kV, 0.1-0.6 Coul/shot) at repetition rates ranging from 0.5 to...
An effective and benign process for copper and lead recovery from waste printed circuit boards (PCBs) was developed. In the process, the PCBs was pre-treated in supercritical water, then subjected to electrokinetic (EK) process. Experimental results showed that supercritical water oxidation (SCWO) process was strong enough to decompose the organic compounds of PCBs, and XRD spectra indicated th...
Background: Anode heel effect refers to reduction of radiation intensity in the anode side of X-ray tube. This variation in radiation intensity across the anode-cathode of X-ray tube can be benefited for decrease radiation exposure in some radiological examinations. The aim of this study was to evaluate the effect of anode heel orientation on the radiation dose received by the testes in male pa...
The new electrical conductive material, copper alloy, C194 in situ composite, has been developed for the application to leadframe, high field magnet and trolley wire. This material has a low cost, high thermal and electrical conductivity, easy fabrication and joining, and also has a wide range of attainable mechanical properties. In C194, copper is one of the core materials in producing leadfra...
Spinel Li4Ti5O12 (LTO) and reduced graphene oxide (rGO) are attractive anode materials for lithium-ion batteries (LIBs) because of their unique electrochemical properties. Herein, we report a facile one-step hydrothermal method in preparation of a nanocomposite anode consisting of well-dispersed mesoporous LTO particles onto rGO. An important reaction step involves glucose as a novel linker age...
