Lanthanum doped Z n 0.5 C o L a x F e 2 − O 4 spinel ferrites were synthesized through the co-precipitation technique. To characterize structural, vibrational, electro-optical, dielectric, and thermoelectric properties, following characterization techniques X-ray diffraction (XRD), Fourier transformation infrared (FTIR) Raman spectroscopy, I–V measurement analysis, UV–vis LCR meter, Seebeck Ene...

The Wiener number of a molecular graph, or more generally of a connected graph, is equal to the sum of distances between all pairs of its vertices. A graph formed by a hexagon in the centre, surrounded by n rings of hexagonal cells, is called an n-Hexagonal net. A graph formed by a series of n hexagonal cells is called an n-Hexagonal chain. The purpose of this paper is to obtain the Wiener numb...

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...
