Effects of Solvent Composition on Liquid Range, Glass Transition, and Conductivity of Electrolytes of a (Li, Cs)PF 6 Salt in EC-PC-EMC Solvents
Electrolytes of 1 M LiPF 6 (lithium hexafluorophosphate) and 0.05 M CsPF 6 (cesium hexafluorophosphate) in EC-PC-EMC (ethylene carbonate-propylene carbonate-ethyl methyl carbonate) solvents of varying solvent compositions were studied for the effects of solvent composition on the lower limit of liquid range, viscosity (as reflected by the glass transition temperature), and electrolytic conductivity. In addition, a ternary phase diagram of EC-PC-EMC was constructed and crystallization temperatures of EC and EMC were calculated to assist the interpretation and understanding of the change of liquid range with solvent composition. A function based on Vogel-Fulcher-Tammann equation was fitted to the conductivity data in their entirety and plotted as conductivity surfaces in solvent composition space for more direct and clear comparisons and discussions. Changes of viscosity and dielectric constant of the solvents with their composition, in relation to those of the solvent components, were found to be underlying many of the processes studied.

Crystal Synthesis and Frustrated Magnetism in Triangular Lattice Cs RE Se 2 ( RE = La–Lu): Quantum Spin Liquid Candidates CsCeSe 2 and CsYbSe 2
A triangular lattice selenide series of rare earths (RE), CsRESe 2 , were synthesized as large single crystals, using a flux growth method. This series stabilized in either trigonal (R$\overline{3m}$) or hexagonal (P6 3 /mmc) crystal systems. Physical properties of CsRESe 2 were explored by magnetic susceptibility and heat capacity measurements down to 0.4 K. Antiferromagnetic interaction was observed in all magnetic compounds, while no long-range magnetic order was found, indicating the frustrated magnetism. CsDySe 2 presents spin freezing at 0.7 K, revealing a spin-glass state. CsCeSe 2 and CsYbSe 2 present broad peaks at 0.7 and 1.5 K, respectively, in the magnetization, suggesting the short-range interactions between magnetic RE ions. Furthermore, the lack of signature for long-range magnetic order and spin freezing down to 0.4 K in these compounds (RE = Ce, Yb) implies their candidacy for a quantum spin liquid state.
