Intrinsic and tunable ferromagnetism in BiNaTiO through CaFeO modification.

New (1-x)BiNaTiO + xCaFeO solid solution compounds were fabricated using a sol-gel method. The CaFeO materials were mixed into host BiNaTiO materials to form a solid solution that exhibited similar crystal symmetry to those of BiNaTiO phases. The random distribution of Ca and Fe cations in the BiNaTiO crystals resulted in a distorted structure.

Preparation and characterization of copper-graphite composites by electrical explosion of wire in liquid.

Copper-graphite nanocomposites containing 5 vol.% graphite were prepared by a powder metallurgy route using an electrical wire explosion (EEW) in liquid method and spark plasma sintering (SPS) process. Graphite rods with a 0.

Synthesis and characterization of conducting polyaniline-copper composites.

Conducting polymer composites have many interesting physical properties and important application potentials. Suitable combinations of metal nanoparticles with conductive polymers can result in composite materials having unique physical and chemical properties that can have wide application potential in diverse areas. In this work, copper nanoparticles were fabricated by electrical explosion of wire (EEW) in solution of polyacrylic acid (PAA) and ethanol.

Preparation and characterization of polyaniline-copper composites by electrical explosion of wire.

Polyaniline-copper composites with a polyacrylic acid (PAA) were synthesized by electrical explosion of wire. Polyaniline (PANI) and PAA were put into the explosion medium, deionized water (DIW) and ethanol, stirred for 24 hrs and sonicated for 2 hrs. These solutions were used as base liquids for explosion process to fabricate Cu nanoparticle.

Production and determination of the magnetic properties of the Fe-36Ni nanopowder via electrical explosion of wire in water and compacted alloy.

Fe-36Ni alloy nanopowder was prepared via electrical explosion of wire in DI water. The nanopowder was reduced in hydrogen at 500 degrees C for 30 min. Spark plasma sintering at 800 and 1000 degrees C for 10 min was used to obtain bulk samples from the hydrogen-reduced nanopowder.
