The Scientific Legacy of Su-Moon Park: a Personal View
Tryk, Donald A. ;
Journal of Electrochemical Science and Technology, volume 4, issue 4, 2013, Pages 119~124
DOI : 10.5229/JECST.2013.4.4.119
The late Professor Su-Moon Park was an exemplary scientist, teacher and human being. It was my good luck and privilege to have had the opportunity of working under his guidance as a graduate student. Herein, I describe briefly the development and growth of some of the ideas in his career and how he and they influenced my career.
Applications of Conductive Polymers to Electrochemical Sensors and Energy Conversion Electrodes
Kim, Dong-Min ; Noh, Hui-Bog ; Shim, Yoon-Bo ;
Journal of Electrochemical Science and Technology, volume 4, issue 4, 2013, Pages 125~139
DOI : 10.5229/JECST.2013.4.4.125
The electrical conductive polymers (ECPs) reported at my research group are introduced in this review, which works are started from the late Professor Su-Moon Park's pioneering research for polyaniline at the University of New Mexico. The electrochemical and spectroelectrochemical properties and their applications to sensor and energy conversion systems are briefly described. At first, the growth and degradation mechanism of polyaniline describes and we extend to polypyrrole, polyazulene, polydiaminonaphthalenes, and polyterthiophene derivatives. In addition, the preparation of monomer precursors having functional groups is briefly described that can give us many exceptional applications for several chemical reactions. We describe the application of these ECPs for the fabrication of chemical sensors, biosensors, biofuel cells, and solar cells.

DOI : 10.5229/JECST.2013.4.4.140
This study describes the electrodeposition of
thin films with a two-step approach that is based on the initial modification of polycrystalline Au electrode with a selenium overlayer followed by a cathodic stripping of the layer as
in a 1 M lactic acid electrolyte containing
ions. For this two-step approach to be effective, the
reduction potential should be shifted to more negative potentials passed potentials for the reduction of Se to
. This was accomplished by the complexation of
ions with lactic acid. The resultant
films were characterized by linear sweep voltammetry combined with electrochemical quartz crystal microgravimetry, UV-vis absorption spectrometry and Raman spectroscopy. Photoelectrochemical experiments revealed that
synthesized thus, behaved as a p-type semiconductor.

We demonstrate that carbon electrodes screen-printed directly on cellulose paper can be employed to perform bipolar electrochemistry. In addition, an array of 18 screen-printed bipolar electrodes (BPEs) can be simultaneously controlled using a single pair of driving electrodes. The electrochemical state of the BPEs is read-out using electrogenerated chemiluminescence. These results are important because they demonstrate the feasibility of coupling bipolar electrochemistry to microfluidic paperbased analytical devices (
) to perform highly multiplexed, low-cost measurements.
Charge Transfer between STM Tip and Au(100) in Dry, H
O, and D

Journal of Electrochemical Science and Technology, volume 4, issue 4, 2013, Pages 153~156
DOI : 10.5229/JECST.2013.4.4.153
Charge transfer between STM tip and Au(100) has been investigated by using a Scanning Tunneling Microscopy (STM) technique in dry,
atmospheres. Dry atmosphere was indicated by humidity as low as 5 % and high humidity as high as 98% was managed by injecting
to the chamber. The current decayed more slowly in high humidity than in dry atmosphere. The plateau currents were found to appear at separations larger than ca.
where the current decay stopped depending on applied bias voltages. The polarity dependence was observed at the STM junction between Pt-Ir tip and the gold. On the contrary, little dependence was seen at the one between Au tip and the substrate electrode.
New Analysis of Electrochemical Impedance Spectroscopy for Lithium-ion Batteries
Osaka, Tetsuya ; Nara, Hiroki ; Mukoyama, Daikichi ; Yokoshima, Tokihiko ;
Journal of Electrochemical Science and Technology, volume 4, issue 4, 2013, Pages 157~162
DOI : 10.5229/JECST.2013.4.4.157
First of all, we express our deepest sympathies for the passing of Professor Su-Moon Park. In the present paper, an electrochemical impedance spectroscopy (EIS), which Professor Su-Moon Park also used frequently for the investigation of electroconducting polymer, is introduced as a recent evaluation tool for a commercially available lithium-ion battery (LIB). The paper surveys how to design equivalent circuits while explaining physical and chemical phenomena in the LIB and how to get more accurate impedance spectra with varying the measuring temperatures. Additionally, a square current EIS (SC-EIS) technique, which we have suggested, is introduced for the larger LIB system as a promising technique for the future.
Preparation of Tantalum Anodic Oxide Film in Citric Acid Solution - Evidence and Effects of Citrate Anion Incorporation
Kim, Young-Ho ; Uosaki, Kohei ;
Journal of Electrochemical Science and Technology, volume 4, issue 4, 2013, Pages 163~170
DOI : 10.5229/JECST.2013.4.4.163
Tantalum anodic oxide film was prepared in citric acid solution of various concentrations and the prepared Ta anodic oxide film was characterized by various electrochemical techniques and X-ray photoelectron spectroscopy (XPS). The prepared Ta anodic oxide film showed typical n-type semiconducting properties and the dielectric properties were strongly dependent on the citric acid concentration. The variation of electrochemical and electronic properties was explained in terms of electrolyte anion incorporation into the anodic oxide film, which was supported by XPS measurements.
