Proton conductor BaZr0.1Ce0.7Y0.1Yb0.1O3│(BZCYYb) have a wide range of applications in solid oxide fuel cell due to its resistance to carbon deposition and good protonic conductivity. In this work, several basic properties of BZCYYb perovskite were studied: Structural phase transitions have been...
Therefore it should not be difficult to fabricate a large-scaled Nb 3 Al stabilized conductor due to easy handling of as-quenched composite during the fabrication processes, such as Cu-plating, stranding, Cu-housing, and/or encasing into conduit. The final annealing can be performed after ...
aThe mobile phase consisted of aqueous formic acid (0.1% in water, solvent A) and acetonitrile (solvent B). 流动相包括的含水甲酸 (0.1%在水、溶剂A) 和乙腈 (溶剂B)。 [translate] athat is as resistant to corrosion as the insulated conductor. 那对腐蚀是一样有抵抗性象被绝缘的指挥。 [...
The deter- mined V-O bond lengths and stretching force constants were found to be in good agreement with experimental data. The estimated band structure and density of states remain in contrast with tight-binding calculations. There is no gap between the conductor and valence bands. According ...

Covered conductor (CC) provides very good cost effective solutions for power sector with respect to the safety aspect of human and wildlife. Mostly, the CCs are insulated with cross-linked polyethylene (XLPE), which is a key factor for safe operation of CC. Many times, premature faults are ...
Potassium metal is soft and white with a silvery lustre, has a lowmelting point, and is a good conductor of heat and electricity. Potassium imparts a lavender colour to a flame, and its vapour is green. It is the seventh most abundant element inEarth’scrust,constituting2.6 percent of its...
Gold is one of the densest of all metals. It is a good conductor of heat and electricity. It is also soft and the mostmalleableand ductile of the elements; anounce(31.1 grams; gold is weighed introy ounces) can be beaten out to 187 square feet (about 17 square metres) in extremely ...
