      Upon warming the 6% Cu-substituted sample in the presence of a 5T magnetic field oriented along the b-axis, a magnetic and structural phase transition is observed at a temperature much lower than those of the magnetic and structural transitions which occur in zero field. Furthermore, these transitions are absent upon cooling in this : Patrick N. Valdivia, Min Gyu Kim, Thomas R. Forrest, Zhijun Xu, Meng Wang, Hui Wu, Leland Weldon Har. Pressure-Dependent Phase Transition of 2D Layered Silicon Telluride (Si 2Te 3) and Manganese Intercalated Silicon Telluride. Two-dimensional (2D) layered silicon telluride (Si 2Te 3) nanocrystals were compressed to 12 GPa using diamond anvil cell techniques. Optical measurements show a color change from transparent red to opaque black indicating a.

    Large-scale Cu2S tetradecahedrons microcrystals and sheet-like Cu2S nanocrystals were synthesized by employing a hydrothermal synthesis (HS) method and wet chemistry method (WCM), respectively. The morphology of α-Cu2S powders prepared by the HS method is a tetradecahedron with the size of 1–7 μm. The morphology of β-Cu2S is a hexagonal sheet-like structure with a thickness of 5–20 by: 7.

Phase transitions in nickel and copper selenides and tellurides by Albert Leendert Nicolaas Stevels Download PDF EPUB FB2

This thesis describes an investigation of phase transitions in metal-rich selenides and tellurides of nickel and copper and in related ternary phases.

Mainly differential thermal analysis and X-ray diffraction at continurly varying temperature were used as experimental techniques (chapter I). In the Ni-Se system, the phases Ni6 Se5 (stable Author: Albert Leendert Nicolaas Stevels.

Thermodynamic data for binary tellurides are compiled and combined with available data for sulfides and oxides to calculate phase relations among tellurides, sulfides, and oxides at low temperatures ( degrees degrees C).Cited by:   Stevels briefly covered this alloy system in his thesis[] about metal tellurides and selenides.A more thorough study was published by Røst and Åkesson[] where they proposed the first and only isothermal section on the system, at \(\,{{^\circ }{\mathrm{C}}}\).The \({\mathrm{CdI}}_{2}\)-type \(\delta \) phase seems to have full solubility between the Fe-Te and Ni-Te binary by: 1.

Here, we report the rational design and controlled synthesis of metallic transition metal selenide NiCo2Se4-based holey nanosheets as a highly efficient and robust OER electrocatalyst. Benefiting from synergistic effects of metallic nature, heteroatom doping, and holey nanoarchitecture, NiCo2Se4 holey nanosheets exhibit greatly enhanced kinetics and improved cycling stability for by:   At 18 kilobars, tin telluride transforms from a sodium chloride-type structure to an orthorhombic crystal structure (space group Pnma).

This structural change is accompanied by a percent increase in electrical by: from semiconducting in the 2H phase to semi-metallic in the 1T′ phase. Among all telluride compounds, MoTe 2 crystal is stable in both 2H and 1T′ phase while WTe 2 only form 1T′ phase in nature (Fig.
