Here, we present a facile method for the fabrication of Ni-based coordination polymer nanoparticles using modulators (e. acetic acid, benzoic acid, or pyridine) to control their size. TEM studies show that the difference in porosity between the different width wires contributes to this variation in resistance response. The impedance change was associated with a change in the depletion width of the semiconductor with varying surface charge at the electrolyte/insulator interface.

First-Principles Investigation of H2O Adsorption on SnO2-TiO2 Gas Sensors. Currently Fe based metallic materials are employed in various devices but regardless of the high permeability the use of Fe based metallic materials is limited to a few kHz due to eddy current losses. A few examples of the questions not yet answered are: how the size of the ions constituting the ionic liquid (ion gel) affects the mechanism of doping (electrostatic vs electrochemical)?
