this study investigates the vertical replacement of salts, variability of electrical conductivity (ec) and soil acidity (ph) due to direct electrical current. a plexiglas cylinder 100 cm in depth with a 14 cm radius was used as a soil container and filled with uniform moist soil to 90 cm. during the experiments, the bottom 10 cm of soil in the cylinder was kept saturated. a steel bar was used a...

Using cost-effective fabrication methods to manufacture a high-performance solid oxide fuel cell (SOFC) is helpful enhance the commercial viability. Here, we report an anode-supported SOFC with three-layer Gd0.1Ce0.9O1.95 (gadolinia-doped-ceria [GDC])/Y0.148Zr0.852O1.926 (8YSZ)/GDC electrolyte system. The first dense GDC fabricated by co-sintering thin, screen-printed layer anode support (NiO–8...

According to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of Cu, Ag, Au, Pb and Se. In this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. Silver was separated from anode slime by using of HNO3 and HCl. X-Ray fluorescence spectroscopy (XRF) was used to characterize anode sl...

Development of solid oxide fuel cell (SOFC) anode with high resistance to coking and sulfur poisoning is highly desirable for the direct application natural gas in SOFC. Herein, a (Cu, Sm)CeO2 anchored Cu nanoparticles has been prepared. Most particle size ranges from 20 50 nm, which can increase conductivity catalytic activity anode. The Cu/CSCO10 supported exhibits maximum power density 404.6...

Anode activity in vacuum arc plays a very important role in both characteristics of vacuum arc and the interruption capacity of vacuum interrupters. In this paper, the transient thermal processes of anode in vacuum arc in a half of arc current cycle with frequency of 50 Hz are simulated by finite element analysis software, ANSYS. Some important phenomena of anode, e.g., the melt and solidificat...

An electrospray ionization ion source coupled to a time-of-flight mass analyzer incorporating a multi-anode time-to-digital converter is described. High-speed data acquisition (kHz mass spectral acquisition) rates are achieved. The four-anode detector produces a significant increase in detection/counting efficiency over that for a single-anode detector. In this work a 2.5 times increase in dete...

microbial electrolysis cell (mec) is one of the promising and cutting-edge technologies for generating hydrogen from wastewater through biodegradation of organic waste by exoelectrogenic microbes. in the mecs, the operational parameters, such as applied voltage (eap), anode surface area, anode-cathode distance, and n2/co2 volume ratio have a significant impact on the hydrogen yield and producti...

in this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. ch4, co2, and h2s, to the various charged particles and syngas in a dielectric barrier discharge (dbd) reactor is studied. an electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. based on the space-time coupled finite element meth...
