..., such as giant magnetoresistance, charge ordering, and metal-insulator transition, have been observed in these compounds. Powder samples of GdBaCo 2 − x Fe x O 6 − δ ( x = 0 ; 0.2 ) were synthesized by glycerol-nitrate method. Oxygen nonstoichiomentry of oxides GdBaCo 2 − x Fe x O 6 − δ ( x = 0 ; 0.2...

...-coating, and screen printing methods. The nanocomposite powders used to improve anode performance were synthesized by selectively coating nanosized NiO particles on ScSZ core particles by the Pechini process. Anode-supported ScSZ electrolytes were fabricated by dip-coating a slurry of Ni-ScSZ composite...

.... DKKK powders have been manufactured using a wet coprecipitation chemical route, and Praxair powders have been produced by spray pyrolysis. The morphology of the powders, as studied by scanning electron microscopy, has been very different. DKKK powders were presented as soft ( ∼ 100 μ m ) spherical...

...B. H. Ryu; I. G. Jang; K. H. Moon; J. Han; T.-H. Lim The stabilized NiO cathodes were fabricated by Li ‐ Co ‐ O coated Ni powder which was synthesized by hydrothermal treatment in 4 - 6 M LiOH ∙ H 2 O . The morphology of Li ‐ Co ‐ O coating was characterized by spectroscopic techniques...

...Jia Rong-Li; Wang Cheng-Yang; Zhu Bin Superfine mesocarbon microbead powders (SFMCMBs) as the new supports for platinum electrocatalysts were first investigated. The Pt ∕ SFMCMB electrocatalysts were prepared by an impregnation-reduction method, with hexachloroplatinic acid as the platinum...
