Intelligent, highly conductive, robust, and flexible electronic textile embedded smart devices hold surging interest in the wearable personalized heating system or thermotherapy. However, designing of these structures with desirable thermotherapy...
A unique and cost effective hydrothermal procedure has been carried out for the synthesis of hexahedron shaped α MnMoO4 and its hybrid composite with graphene using three different weight percentages of graphene. Characterization techniques, such as XRD, Raman and FTIR analysis, established the phase and formation of the composite. The electrochemical characterization of the pseudocapacitive MnMoO4 and the MnMoO4/graphene composites in 1 M Na2SO4 displayed highest specific capacitances of 234 F g(-1) and 364 F g(-1), respectively at a current density of 2 A g(-1). Unlike many other pseudocapacitive electrode materials our prepared materials responded in a wide range of working potentials of (-)1 V to (+)1 V, which indeed resulted in a high energy density without substantial loss of power density. The highest energy densities of 130 Wh kg(-1) and 202.2 Wh kg(-1) were achieved, respectively for the MnMoO4 and the MnMoO4/graphene composite at a constant power delivery rate of 2000 W kg(-1). The synergistic effect of the graphene with the pseudocapacitive MnMoO4 caused an increased cycle stability of 88% specific capacitance retention after 1000 consecutive charge discharge cycles at 8 A g(-1) constant current density, which was higher than the virgin MnMoO4 with 84% specific capacitance retention.
A corrosion test of galvanized steel and aluminum was carried out in three different aqueous environments, 5% NaCl solution, sea water and rain water, using the immersion test technique. Corrosion rate was measured in mdd (mg/dm 2 /day) units. Aluminum was considered as a possible alternative to galvanized steel. The corrosion characteristics of the corroded samples were investigated by XRD, XRF and SEM analysis. Although various results were obtained all through this study, aluminum was seen as more corrosion resistant than galvanized steel in the conditions tested in all three aqueous environments. Galvanized steel might be more corrosion resistant than aluminum in long term exposure in rain water. Without taking into account cost comparisons, aluminum can be used as a substitute for galvanized steel in industrial structures (roofing sheets) and water distribution systems.
