Electrochemical characteristics of zinc oxide-polyethyleneglycol complex films using EQCM.

ZnO-PEG-ZnO complex film was fabricated by forming ZnO thin film on the Polyethyleneglycol (PEG) thin film. ZnO thin films were formed by an electrostatic method and ZnO-PEG complex films were fabricated by adsorbing PEG on the ZnO thin films surface with hydrogen bond. The electrochemical characteristic of the ZnO-PEG-ZnO film was analyzed by EQCM techniques.

Morphology analysis of sodium chloride crystallization on the mica substrate using atomic force microscope.

The morphology of the specific face growth of sodium chloride (NaCI) crystal on the mica surface was analyzed using atomic force microscope (AFM). The supersaturation of the NaCI was induced to lead to the crystal nucleation and growth by the addition of methylalcohol. The effects of methylalcohol concentration and mica surface functionality on the NaCI crystal growth morphology were investigated.

Evaluation of interaction between histidine binding Cu2+ ion and histidine by atomic force microscopy.

This paper presents a direct interaction force measurement between histidine molecules using AFM force-distance curve measurement. AFM force-distance curves between the histidine-modified cantilever and substrate in the different conditions with or without intercalating Cu2+ ion were measured and interpreted via Gaussian curve fitting analyses. The adhesion force between histidine molecules was shown to be 110 pN under the presence of Cu2+.

Development of glucose sensor using two-photon adsorbed photopolymerization.

A novel glucose sensor was constructed, and its analytical potential examined. A chip-type three-electrode system for use in a flow-type electrochemical glucose sensor was fabricated using a UV lithography technique on a glass slide. An Ag/AgCl reference electrode was made by electroplating silver onto a Pt electrode and dipping in a saturated KCl solution for 30 min.

[A comparative study on family perception between abused children and normal children by Kinetic Family Drawing].

Purpose: The study attempted to find family perception differences between abused children and normal children by Kinetic Family Drawing.

Method: The subjects of the study consisted of two groups, 143 abused who were in the upper 25th percentile, and 150 normal who were in the lower 25th percentile. Collected Kinetic Family Drawings were divided into five dimensions such as actions, human figure characteristics, dynamics, styles and symbols, and they was analyzed with SPSS/WIN 10.
