Li2CuSnO4 and Li2CuSnSiO6 were prepared from their precursors compounds using Brij surfactant and a hydrothermal autoclave method. X-ray diffraction characterization revealed that the crystal structures of these compounds were tetragonal. Scanning electron microscope investigation showed the particle size morphology of Li2CuSnSiO6 is larger than that of Li2CuSnO4. Electrochemical impedance spectroscopy (EIS) explained that Li2CuSnO4 cell had higher charge transfer resistance (Rct = 2936Ω) than that of Li2CuSnSiO6 (38Ω). Furthermore, the reversible specific discharge capacity of the Li2CuSnSiO6 …

One of the most important properties of very recently reported FeSe based superconductors is the robustness of their superconductivity under applied magnetic field. The synthesis and control of superconductivity in FeSe based compounds is rather a difficult task. Synthesis and physical property characterization for optimized superconductivity of FeSe1/2Te1/2 at 13 K is reported here. The compound crystallized in a tetragonal structure with lattice parameters a=3.8015(2) and c =6.0280(4) Å. Magnetization measurements indicated bulk superconductivity with lower critical field (Hc1) of around 180 Oe. By applying Ginzburg–Landau theory, the Hc2(0) value is estimated to …
