18 cze 2021 · Terpyridine-functionalized Ti nanospike electrodes (TiNS-SiTpy) were developed and applied to cyclic voltammetry and amperometry of Ln (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb) ions and mixed Eu (III) + Ln (III) ions in a 0.1 M NaClO4 electrolyte.
14 lis 2019 · Partial Ti-substituted Na 2/3 Mg 1/3 Ti 1/6 Mn 1/2 O 2 enables significant improvements on electrochemical properties with respect to the stability of high-voltage plateau and total reversible capacity (∼230 mAh g−1).
2 paź 2017 · This review intends to provide more recent information on the binary phase diagrams for the Ag-Ca, Al-Yb, As-Fe, B-Zr, Co-U, Cu-Se, Cu-Th, La-Mo, Mg-Sn, Mo-Th, Sn-Ta, and Te-Ti systems that have become available after 1990.
22 maj 2017 · W artykule opisano kilka sprawdzonych metod i zasad dotyczących tej czynności. Pętla regulacji to mechanizm sterowania oparty na sprzężeniu zwrotnym, które usiłuje korygować rozbieżności pomiędzy mierzoną wartością zmiennej procesowej a pożądaną wartością zadaną (punktem nastawy).
1 wrz 2021 · In this work, an alternative set of thermodynamic parameters was obtained with the help of first-principles calculations. And Eu 1-x Te was modeled by a new sublattice model based on the first-principles calculations results.
