The Stabilization of Niobium-Based Solid Electrolyte Capacitors

Development of fractional order capacitors based on electrolyte processes

In recent years, significant research in the field of electrochemistry was developed. The performance of electrical devices, depending on the processes of the electrolytes, was described and the physical origin of each parameter was established. However, the influence of the irregularity of the electrodes was not a subject of study and only recently this problem became relevant in the viewpoint...

Niobium Powder Synthesized by Calciothermic Reduction of Niobium Hydroxide for Use in Capacitors

Metallic niobium powder was produced for applications in electric capacitors via calciothermic reduction of niobium hydroxide in molten CaCl2. Sub-micrometer spherical metallic particles with coral-like morphologies reflected the particle size of the starting oxide powder. A fine powder was obtained from the mixtures of niobium hydroxide and CaO or Ca(OH)2, respectively. Sintered pellets of the...

Reliability of Solid Tantalum Capacitors

the role of task-based techniques on the acquisition of english language structures by the intermediate efl students

this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...

Study of MG49-PMMA Based Solid Polymer Electrolyte

The studies of rubber-polymer blends as solid polymer electrolyte for electrochemical devices application have been investigated. The electrolyte films were prepared by solution casting technique. The effect of poly(methyl methacrylate) (PMMA) and lithium tetrafluoroborate (LiBF4), salt concentration on chemical interaction, ionic conductivity, structure and morphology of 49% poly(methyl methac...
