The development of co-precipitation method for preparing metal-oxide nanoparticles Powder is very practical materials for further processing, to be used as a bulk, slab, pellet, even film as well as solution or colloid. Price of commercial powder is generally dependent ...
High-resolution neutron diffraction studies on NdxY1−xBa2Cu3O7−δ superconductors A synthesis of neodymium-substituted YBCO superconductor NdxY1−xBa2Cu3O7−δ (x=0,0.25,0.5,0.75,1) has been done using a dissolved method in order to obtain homogeneous crystals and higher critical current density. The effects of the substitutions on the ...
Weak ferromagnetism in normal state Bi2Sr2CaCu2O8+d nano-superconductors Superconducting nano powders Bi2Sr2CaCu2O8+d (Bi-2212) was synthesized using a wet mixing method, where all the basic material is completely dissolved using HNO3 solution. The basic ingredients were Bi2O3, SrCO3, CaCO3, and CuO. The ...
Polyaniline/Fe3O4 as conducting/magnetic polymeric composites In daily uses, a polymer is generally known as insulator, both electrically and thermaly. For several types of certain polymers, the electrical conductivity can be dramatically improved which can reach more than 10 orders of ...
TiO2 powder and its photocatalytic activity Titanium dioxide (titania) nanoparticle were synthesized by coprecipitation process of titanium trichloride (TiCl3) in aqueous medium, with NH4OH as pH regulator. The pH solution was varied during the synthesis process between pH 3-8.4, and ...
