We have developed an infrared imaging setup enabling in situ infrared images to be acquired, and expanded on capabilities of an infrared imaging as a high-throughput screening technique, determination of a critical thickness of a Pd capping layer which significantly blocks infrared emission from below, enhancement of sensitivity to hydrogenation and dehydrogenation by normalizing raw infrared intensity of a Mg thin film to an inert reference, rapid and systematic screening of hydrogenation and dehydrogenation properties of a Mg–Ni composition spread covered by a thickness gradient Pd capping layer, and detection of formation of a Mg2Si phase in a Mg thin …

This work reports on the transport properties of NH4NO3 doped methyl cellulose (MC) polymer electrolyte. The polymer electrolyte films were prepared by the technique of solvent casting. The highest room temperature conductivity of MC doped with 25 wt.% NH4NO3 is 2.10 +/- 0.37 x 10(-6) S cm(-1). Conductivity-temperature relationship obeys the Vogel-Tamman-Fulcher (VTF) rule from which the glass transition temperature, T-g was evaluated. The mobility, p and number density of charge carrier, n were calculated using the Rice and Roth model. (C) 2010 Elsevier B.V. All rights reserved.
