Polyaniline (PANI) is one of the most promising material which is frequently used as electrode material for supercapacitor due to its four oxidation states which contribute to its high specific capacitance. The excellent electrode required for the supercapacitor consists of good electronic conductivity, electrochemical stability and high surface area. The electronic conductivity of green protonated emeraldine form of PANI is lower than that of metals. So, one of the challenging issues in development of high performance supercapacitor is to improve its electronic conductivity of the PANI...

Saving energy in the building sector and automotive industry is a major global socio-economic target in energy efficiency as well as from environmental viewpoint. Electrochomic smart windows are the future of the building envelope. It allows people to dynamically control the heat and light flow into a building depending on the needs of the occupant and the changing outside environment. NiO has been studied intensively for used as an active material for anodically coloring electrode in electrochromic devices. The potential application of nanostructured material depends upon its properties. It...
