“…The conductive mechanism of doped PANI differs from metal and semiconductor, in which the carriers are composed of "delocalization" π electrons and solitons, polarons or bipolarons formed by doping (Li and Zhao, 2000), which has been described by PEACE Model (Nechtschein et al, 1987;Wang and Wang, 1990), Granular Metal Island Model (Javadi et al, 1989;Lundberg and Salaneck, 1987;Nechtschein et al, 1989) and Monopole and Bipolar Sub-transformation Model (Wang et al, 1991). Meanwhile, PANI has activity surface that exceeds geometric surface and can play a role in selective catalysis to some certain surfaces when used as the electrode materials, for example, the electrocatalytic oxidation of ascorbic acid at polyaniline film modified glassy carbon electrodes (Dong and Song, 1992), the electrocatalysis of polyaniline film on Fe [II] and Sb [II], the synergistic effects of electrocatalytic oxidation of polyaniline on small organic molecules (DuIć and Griglć, 2001;Mikhaylova et al, 2001;Rajendraprasad and Munichandraiah, 2002) and the same electrocatalytic activity for Pb/PANI and Pt/PANI in acid solutions (Cheraghia et al, 2009). Therefore, the co-deposition of WC and PANI particles as conductive matrix and electrocatalytic activity substance and their dispersion distributions in the composite inert anodes, obviously improve the electrocatalytic activity and decrease the overpotential of oxygen evolution for Al/Pb-PANI-WC composite inert anodes in a synthetic zinc electrowinning electrolyte of 50 g·L − 1 Zn 2+ and 150 g·L − 1 H 2 SO 4 at 35°C.…”

The polyaniline (PANI)‐coated functionalized multi‐walled carbon nanotubes (f‐CNTs) and silver nanoparticles (AgNPs) (PANI@f‐CNTs and PANI@AgNPs hybrid nanofillers) are synthesized by means of in situ polymerization of aniline monomer on the surface of f‐CNTs and AgNPs. The PANI@f‐CNTs and PANI@AgNPs hybrid nanofillers were successfully incorporated into the polymethyl methacrylate (PMMA) matrix through in situ polymerization of methyl methacrylate. The Fourier transform infrared spectroscopy analysis reveals that the existence of strong interfacial adhesive bonding between PANI@f‐CNTs and PANI@AgNPs hybrid nanofillers and PMMA matrix. The X‐ray diffraction (XRD) analysis indicates that there is no change in position of the diffraction peak as a result crystallinity of the samples are not much affected by the addition of hybrid nanofillers. The transmission electron microscopy and scanning electron microscopy analysis displayed that the phase morphology of the PMMA nanocomposites is significantly changed as well as hybrid nanofillers are homogeneously dispersed within the PMMA matrix. The AC conductivity (σac), dielectric permittivity (ɛ′) dielectric loss (tan δ) of the PMMA nanocomposites are remarkably increases whereas the real impedance (Z′) decreases by the Incorporation of the hybrid nanofillers into the PMMA matrix, which concludes that the synthesized polymer materials have most promising dielectric application.

Background: In the process of work to gain the maximum results, a radiologist needs a viewing box tool to read radiographs. Therefore, the authors want to develop a viewing box tool, which in general the work if this tool resembles the factory manufactured tool. The viewing tool box made can adjust the intensity of the light produced.Objective: to create a viewing box tool by using a potentiometer system.Methods: This study used applied research method by creating and using the design of viewing box tool by using a potentiometer system and testing the viewing box tool created by using a Lux meter and 15 respondents consisting of five radiologists and 10 radiographers who should fulfill the questionnaire form.Results: The mean of viewing box illumination reached 220 lux. The results of the questionnaire showed that 100% radiologist gave an A (excellent) and expressed that the viewing box tool created could be used properly and 90% radiographers provided an A (excellent) and expressed that the viewing box tool created could be used properly, while 10% radiographer gave a value of B (moderate).Conclusion: viewing box tool created could be used properly and obtained optimal results as a tool in reading radiographs. Potentiometer system contained in the viewing box was very helpful in reading radiographs because it allowed to adjust the light intensity according to user needs.Keywords : Viewing box, Potentiometer Bibliography : 1980-2011
