    In this article, we presented the indium tin oxide (ITO) and aluminum zinc oxide (AZO) thin film as the new transparent conductive oxide (TCO) coating on the flexible and transparent polydimethylsiloxane (PDMS) substrate by RF sputtering. The elastomer PDMS can stand much higher temperature up to 200°C. The PDMS has an advantage over the other commercially used polymers such as PET, PEN in electronic devices due to its high temperature resistance. In this article, we have discussed the electrical and optical properties for ITO and AZO thin film on PDMS substrate. The dye sensitized solar cells (DSSC) were fabricated on the stainless steel substrate as counter electrode and transparent TCO coated PDMS substrate as a front electrode. Our focus is to demonstrate the conductive layer on new flexible, transparent PDMS polymer material that can stand higher temperature and can be used for the electronic device such as DSSC.

    In the present study, mechanism of the chitosan modified screen-printed electrode catalytic reaction was described and experimental conditions were defined for the determination of peroxide value in vegetable oil using differential pulse anodic stripping voltammetry. Due to the fact that protonated chitosan can absorb only iodide ion, chitosan modified electrode was applied to determine the oxidation process of iodide. Results showed that the peak current value decreased with increasing peroxide value in the vegetable oil and reveled a good correlation (R = 0.9914) with the peroxide in the concentration range of 0.01–3.2 µg/mL. Moreover, the peroxide value measured in the vegetable oil using chitosan modified electrode was in agreement with the results obtained using standard iodometric method.

    We have developed aluminum (Al) foil using an electrodeposition technique (electrodeposited Al foil) in dimethylsulfone-based organic electrolyte solution. The electrodeposited Al foil was suitable for the current collector of lithium ion batteries (LIB) because of its high surface roughness and excellent wettability compared with those of conventional Al foil produced by rolling methods. The electrodeposited Al foil showed excellent electrochemical stability under anodically polarized conditions. These characteristics are attributed to the crystal orientation, the crystal structure and the composition of the electrodeposited Al foil. The electrochemical characteristic of the positive electrode using this Al foil was almost the same as that using conventional Al foil, while the resistance of the positive electrode using the electrodeposited Al foil was lower than that using conventional Al foil. These electrochemical characteristics are probably due to the above mentioned physical properties of the electrodeposited Al foil. These properties also influenced the cycle efficiency and/or cycle life of the battery under high rate conditions.
