Material research for energy storage is increasing in an effort to find alternative renewable energy devices. A lot of thermal energy wasted in everyday life. Research for various alternative high-capacitance supercapacitor materials continues to be encouraged. SrTiO3 shows good electrical and dielectric properties, as wellas defect induced structure. Modification of local structure using Pb dopant on the SrTi1-xPbxO3 was applied for exploring the scientific information and its potential applications intensively. The synthesis of SrTi1-xPbxO3 was prepared by solid-state reaction method. The powder was then calcined, pressed into a pellet, and subsequently sintered at 860°C. Various fraction of lead (Pb) dopants were carried out in 0.00; 0.02; 0.04; 0.06; 0.08; 0.1 molar ratio. The structure, morphology, and supercapacitor properties of SrTi1-xPbxO3 composite powder was performed by using X-Ray Diffraction, UV-Vis, IV temperature-induced conductivity and CV EIS. XRD data analysis with Cu-Kα wavelength indicated the single phase was identified and a slight change in lattice parameters was observed. Sixfold symmetry of the local octahedral structure also changed to a tetragonal structure after introducing the amount ofPb element. For investigating electrical properties of SrTi1-xPbxO3, I-V meter was applied. Furthermore, electrical conductivity and dielectric constant will be discussed in detail. Loading higher Pb fraction promoted the electrical conductivity measured at various temperatures. Increasing conductivity is one indicator that this system potentially enhanced the electronic exchange of supercapacitor in SrTi1-xPbxO3 system. [ABSTRACT FROM AUTHOR]

Natural polymers can be extracted from leaf or stem of plants. Pterocarpus Indicus W. (PIW) and Jatropha Multifida L. (JIL) plants are good candidate as natural polymer sources. PIW and JIW polymers contain chemical compound so-called flavonoids which has C6-C3-C6 carbons conjugated configuration. The renewable type of polymer as well as their abundancy of flavonoid provide us to explore their physical properties. A number of research have been reported related to broad synthesis method and mechanical properties. So far there is no specific report of electrical conductivity associated to PIW and JIL natural polymers. In order to obtain electrical conductivity and its crystallinity of the extracted polymer films, it was induced on them a various fraction of silver nano particles. The film has been prepared by means of spin coating method on nickel substrate. It was revealed that FTIR spectra confirm the existing of rutine flavonoid. The crystallinity of the samples increase from 0.66%, to 4.11% associated to the respective various of silver fractions of 0.1 M to 0.5 M. SEM images show that there are some grains of silver in the film. The nature of electric conductivity increases a long with the addition of silver. The electrical conductivity increase significantly from 3.22 S/cm, to 542.85 S/cm. On the other hand, PIW films also shows similar trends that increase of Ag induce the increase its crystallinity as well as its electrical conductivity at semiconducting level. This result opens a prospective research and application of the green renewable polymer as optoelectronic materials. [ABSTRACT FROM AUTHOR]
