Electrolytic hydrogen charging experiments on cold-deformed and well-annealed (annealing at 700 °C for 2 h) pure titanium samples were carried out, respectively. Positron annihilation spectroscopy X-ray diffraction used to characterize all experimental explore the formation of vacancy defects storage form in after charging. Results showed that hydrides formed electrolytic charging, but a new ph...

Electrolytically generated hydrogen gas used to measure local blood flow by Stosseck et al. The data obtained by their method, however, did not correlated well with that obtained by original Aukland's method, hydrogen clearance method. We have tried to record the concentration of hydrogen gas after electrolytic generation of hydrogen gas at the white matter of the mongrel dogs. As a result, we ...

Electrolytic manganese dioxide (EMD) was prepared by using gas diffusion electrode (GDE) instead of traditional hydrogen evolution cathode. Sulfate acid’s effects on the cell voltage, the current efficiency, the electro-catalytic activity and the lifetime of GDE are studied. The results show that as the concentration of sulfuric acid increases, the current efficiency increases, while the cell v...

P. Vaňová, J. Sojka. VŠB Technical u niversity of O strava, FMME, Ostrava, Czech Republic This paper is dealing with hydrogen embrittlement of austenitic-ferritic 2205 duplex steel using the slow strain rate test (SSRT). The original material was subjec ted to heat treatment under 700 °C during 5 hours and f ollowing aircooling with the aim of pr ovoking sigma phase pr ecipitation and embrittle...

Hydrogen is readily obtained from renewable and non-renewable resources via water splitting by using thermal, electrical, photonic and biochemical energy. The major hydrogen production is generated from thermal energy through steam reforming/gasification of fossil fuel. As the commonly used non-renewable resources will be depleted in the long run, there is great demand to utilize renewable ener...

Title of Document: RELIABILITY EVALUATION OF LIQUID AND POLYMER ALUMINUM ELECTROLYTIC CAPACITORS 45BAnshul Shrivastava, Doctor of Philosophy (Ph.D.), 2014 Directed By: Professor Michael Pecht, Department of Mechanical Engineering Liquid aluminum electrolytic capacitors are known for their reliability problems. They are considered as the weakest link in the power electronics system. The liquid e...
