It is known that a non-local complex fermion can be written in terms of two Majorana fermions. We exploit this fact to explain the system zero modes bound vortex and an anti-vortex, on surface topological insulator contact with s-wave superconductor, as fermion. Although current density single mode vanishes, by starting wave packet consisted positive negative energy fermions, we specify time-de...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

Obejective(s): In this research, magnetite nanoparticles with an average size of 23-36 nm were successfully synthesized via surfactant-free electrochemical method using iron as the anode and water as the electrolyte in a closed aqueous system in the presence of NaOH at room temperature. Methods: The effect of the current density on product formation...

Results of a study of an electrolytic device that can produce excess power are presented. The power calibration procedure used for the experiments and the data analysis procedure is briefly described in this paper. Different combinations of cathode and electrolyte were investigated. Thin foils of different pure metals were and thin spattered layers of different pure metals on different substrat...
