Glycine-assisted hydrothermal synthesis of NiCo2S4 as an active electrode material for supercapacitors

open access: yesJournal of Science: Advanced Materials and Devices, 2019
Nickel cobalt sulfide (NCS) was synthesized from nickel and cobalt nitrate (NCS-1) by a hydrothermal method. In another method, nickel cobalt sulfide (NCS-2) was also synthesized from hydrothermally synthesized nickel cobalt oxide (NCO). The syntheses of

Chemical potential jump between hole- and electron-doped sides of ambipolar high-Tc cuprate [PDF]

open access: yes, 1999
In order to study an intrinsic chemical potential jump between the hole- and electron-doped high-Tc superconductors, we have performed core-level X-ray photoemission spectroscopy (XPS) measurements of Y0.38La0.62Ba1.74La0.26Cu3Oy (YLBLCO), into which one
