The terahertz complex permittivity of the molecular plastic crystal succinonitrile (SN) or 1,2 dicyanoethane (N≡C−CH2−CH2−C≡N), doped with the lithium salts LiBF4, LiPF6, LiTFSI, and LiClO4 to form solid-state plastic crystal electrolytes, is measured and compared using temperature-dependent terahertz time-domain spectroscopy (THz-TDS). In contrast to the trends at low frequency, SN’s terahertz...

As the consumer demand for smaller, more sophisticated computers grows, the need arises for new air cooling methods that will work in geometries that mechanical fans cannot. Ionic winds (also known as electrohydrodynamic flows) are flows that are produced by the generation of a gas discharge. These flows do not require moving parts to operate, making them attractive for small form-factor device...

Single crystals of In2.24(N CN )3 and N aIn(NCN)2 can be synthesized from a reaction be­ tween InBr and NaCN at 400 °C, followed by chemical transport at 400-500 °C. The X-ray crystal structure determinations of In2.24(NCN)3 (rhombohedral R 3c, a = 606.09(4), c 2884.4(2) pm, Z = 6) and NaIn(NCN)2 (orthorhombic Cmcm, a = 961.30(6), b = 716.84(5), c = 603.65(4) pm, Z = 4) reveal ionic layer struc...

Self-assembly of a binary monolayer of charged particles is modeled using molecular dynamics and statistical mechanics. The equilibrium phase diagram for the system has three distinct phases: an ionic crystal; a geometrically ordered crystal with disordered charges; and a fluid. We show that self-assembly occurs near the phase transition between the ionic crystal and the fluid, and that the rat...

Crystal structure of zwitterionic trimethylammoniopropane sulfonate (Z1-Methyl) was determined by single-crystal X-ray diffractometry. Z1-Methyl crystallized in the monoclinic system, space group P2(1), with a = 6.3639(2), b = 10.9237(4), c = 8.1505(4) A, beta = 111.078(2) degrees, V = 528.69(4) A3, Z = 2. An inter-molecular ionic association was observed in the crystal. The shortest distance b...

A QCM device employing ionic liquids as the sensing materials for organic vapors has been developed and evaluated. The sensing mechanism is based on the fact that the viscosity of the ionic liquid membrane decreases rapidly due to solubilization of analytes in the ionic liquids. This change in viscosity, which varies with the chemical species of the vapors and the types of ionic liquids, result...
