In the framework of the superconducting proton linac (SPL) study at CERN, a new non-cesiated H(-) plasma generator driven by an external 2 MHz RF antenna has been developed and successfully operated at repetition rates of 50 Hz, pulse lengths of up to 3 ms, and average RF powers of up to 3 kW. The coupling efficiency of RF power into the plasma was determined by the cooling water temperatures a...

Modified TiO2 nanomaterials are considered to be promising in energy conversion and ferrites modification may be one of the most efficient modifications. In this research, various ferrites, incorporated with various cations (MFe2O4, M = Ni, Co, Zn, and Sr), are utilized to modify the well aligned TiO2 nanorod arrays (NRAs), which is synthesized by hydrothermal method. It is found that all MFe2O...

Along with magnetic properties, the spinel ferrites exhibit promising electrical properties, deployment of which results into evolution of new area of applications as the electronic sensor materials.

(Bi,Sr)FeO3-δ (BSF) cathode materials doped with either Co, Ni or Mn are synthesized by an ethylene diamine tetra-acetic acid (EDTA)-citrate complexing method, and the effects of the doping level on the mixed electronic-ionic conductivity at various temperatures are studied up to 800 °C. The phase purity and solid solution limit are investigated by X-ray diffraction (XRD). The ionic conductivit...

Cooling rates of 10 -3 K/yr. permit naturally occurring Mn-Zn ferrites (franklinltes) to be in thermodynamic equilibrium at ambient temperatures with respect to both electrostatic and elastic energies. The elastic strain energy resulting from the occupancy of the A sites by ions of differing sizes is minimized by clustering of.Mn and Zn in different regions of a D/ crystal. Using Fe NGR, these ...

The spinel ferrites are famous due to their unique electrical and magnetic performance. current inspection is about the features of Holmium (Ho) substituted Co-Zn-ferrites (Co0.6Zn0.4HoxFe2−xO4; where x = 0.0 0.1). Single-phase cubic configuration prepared was perceived from X-ray diffraction data. sample has one order larger direct (dc) resistivity as compared un-substituted sample. substituti...

Ferrites are important magnetic materials used in electronic devices. Nanocomposites of ferrites with TiO2, SiO2 and carbon quantum dots have gained recent interest due to their unique advantages, such as high chemical stability, surface-active sites, specific surface area, non-toxicity, excellent optical properties, tunable porosity.
