本研究では、電気化学系において双安定状態を誘起し、その環境下での顕微分光により、この協同化学反応の分子レベルでの機構解明を試みてきた。平成18年度においては、前年度の成果を元に、実際に顕微分光法を用いて研究を進め、以下に示す成果を挙げた。1.電気化学反応波のチューニング電気化学系で現れる化学反応波の発現機構を解明し、そのチューニング法を数理モデルに基づく数値計算・非線形分岐解析により確立した。この成果に基づき、界面活性剤の電極表面上での周期的吸着・脱離を伴う反応波の制御が可能であることを実験的に示した。2.電気化学波の伝播を伴うAu薄膜成長過程の顕微分光による追跡電気化学波の振動伝播を伴う気液界面上でのAu薄膜成長過程を顕微可視光吸収および顕微ラマン散乱(SERS)によりその場追跡した。その結果、自発的な電位振動に同期したSERS強度の増減が観測された。SEMによる構造解析などから、これはナノ微結晶の集合体からなる薄膜が、化学波の伝播に同期して連続膜へとその形を変えることに起因することが明らかとなった。

In this study, the Department of Electro-Chemical Engineering and the Department of Electro-Chemical Engineering are in a state of stability. In the ambient environment, the differential photometer and the chemical reaction molecular mechanism are used to explain the mechanism. In Pingcheng, the results of the previous year were reviewed, the results of the previous year were reviewed, and the differential photometry of the International Academy of Sciences was studied. The results are shown below. 1. The chemical counter-wave analysis of the department of electrical chemistry and the chemical anti-wave analysis of the department of electrical chemistry have proved that the mechanism of chemical anti-wave analysis of the department of electrical chemistry is the basis of mathematical and physical analysis. Based on the results, the absorption and desorption cycle of the cathode on the surface of the electrode, together with the anti-wave control, may affect the performance of the cathode. two。 The growth process of Au film in the presence of electronic chemical wave broadcasting is characterized by differential optical tracking, differential optical tracking, vibration broadcasting, and the growth process of Au film on the liquid interface. The growth process of Au film on the liquid interface is microscopically absorbable, micro-dispersive (SERS), and field tracking. The result of the test, the self-operated electric potential vibration, the SERS strength of the same period, the strength of the electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibration, the strength of the self-operated electric potential vibrator, the self-operated electric potential vibration and the self-operated electric potential vibration. SEM micrographs, microcrystals, aggregates, thin films, chemical waves, and chemical waves were used to analyze the cause of the film.
