Novel cyclotetrasiloxane tetraimidazolium salts as high performance quasi-solid state electrolyte for dye-sensitized solar cells
A new type of quasi-state ionics based on cyclosiloxane imidazolium iodides was synthesized and used as electrolytes in dye-sensitized solar cells (DSSCs). The cyclosiloxane electrolyte formed a distinctive ca...

Using Lattice Energies to Model the Physical/Chemical Behavior of a Doped Refractory Oxide
The calculated lattice energies apparently reflect the hydration susceptibility as a function of dopant species. While the experimental work done in this area is limited, what is reported in the literature sup...
