ジャーナル フリーTwo new voltammetric techniques coupled with lasers are mainly described. One is laser thermal modulation voltammetry (LTMV), in which the intermittent laser beam serves as a heater modifying a temperature of the electrode and its surroundings periodically. The other is laser ablation voltammetry (LAV) in which the electrode surface is successively renewed or activated by an ablation action of the laser pulse. LTMV is useful for detecting not only a standard entropy change of the electrode reaction but also photo-induced phenomena such as photo-adsorption or -desorption at the electrode surface. On the other hand, LAV is a promising technique overcoming the deactivation of the solid electrode which electrocheniists have been suffering from for a long time. Further, LAV provides a stationary voltarnmogram, which is quite similar to a polarogram obtained by using a dropping mercury electrode (DME). Applying experimental techniques for transient optical spectroscopy to LAV allows us to carry out a time-resolved measurement even in the voltammetric experiment, which leads to a study of primary processes of the electrode reaction and a measurement of a potential of zero charge (PZC) on the solid electrode. A new field of electrochemistry is expected by applying various laser techniques to classical voltammetry.抄録全体を表示PDF形式でダウンロード (4682K) -

ジャーナル フリーMediated bioelectrocatalysis based on microbial whole cells are described. Microbial whole cells immobilized on electrodes work as biocatalysts in the electrolytic oxidation or reduction of substrates in the presence of electron transfer mediators between the electrodes and the cells. The catalytic current reflects the characteristics of the microbial cells, such as the membrane permeability, the enzyme reaction rate in the cells. The kinetic features of the bioelectrocatalysis are discussed on the basis of the theory of biocatalyst electrode. Their application to biosensor and bioreactor are also mentioned.抄録全体を表示PDF形式でダウンロード (1377K) -

ジャーナル フリーReductive desorption of selcassembled monolayers of thiols is reviewed. Cyclic voltammetry for the reductive desorption of adsorbed thiols is sensitive to not only the chain length and the kind of the terminal functional group but also the state of adsorbed thiols. The importance of the elucidation ofthe relationship between microscopic structure studied by scanning probe microscopy and cyclic voltammograms for the reductive desorption is emphasized. The reductive desorption is also useful to form phase-separated binary monolayers into nanometer-scale by the electrochemical selective replacement of adsorbed thiols.抄録全体を表示PDF形式でダウンロード (6513K) -

ジャーナル フリーThe electrochemical studies on the ion transport from one aqueous (W1) to another (W2) across a bilayer lipid membrane (BLM) are reviewed. The membrane transport includes ion transfers at W1/BLM and BLM/W2 interfaces and diffusion of ions within the BLM. The membrane potential, hitherto, has been treated as the resultant of the interfacial potentials represented by Donnan potential and the diffusion potential expressed by Henderson or Goldman equations. In case of evaluation of the characteristics of ion permeation, diffusion process has been regarded as significant. The authors found based on the voltammogram for ion transport through a membrane, however, that various phenomena observed with the ion transport were elucidated by taking into account the conjugated ion transfers at W1/BLM and BLM/W2 interfaces. The relation between the shapes of voltammograms and properties of added ions, coexisting ions and lipids composing BLMs was also clarified.抄録全体を表示PDF形式でダウンロード (2830K)
