The precursors with NiCO3 · 2Ni(OH)2 · 2H2O, Fe2O3 · nH2O coated alumina microspheres were prepared by the aqueous heterogeneous precipitation using metal sa
Bulk polycrystalline samples of La0.60Sr0.4MnO3 and La0.60Sr0.25-yNa0.15ΔyMnO3 with 0.00≤ y ≤0.15 ("Δ" representing cation vacancy) were successfully synthe
The erosion behavior of a nanocomposite W-Cu material under arc breakdown was investigated. The arc erosion rates of the material were determined, and the erode
The pulling rate in czochralski silicon (CZSi) growth is important for reducing the cost of solar cell.In this paper, double-heater, heat shield and composite a
By analyzing some existing test data generation methods, a new automated test data generation approach was presented. The linear predicate functions on a given
Ferrous ion was transformed into feroxyhyte (δ-FeOOH) by oxidation. Then, manganese sulfate and zinc sulfate in some ratio were added to the feroxyhyte solutio
