Surface treatment, electrochemical

For example, the final heat treatment temperatures In the manufacture will produce different electrochemical properties, even with the same surface treatments (2-4) since the structure and electrical property of glassy carbon depends on the temperature, as Indicated by the single crystal TEM patterns and by measurement of temperature dependent conductivity (5-6). On the other hand. It Is also well established that the electrochemical properties of carbon-based electrodes are markedly affected by surface treatments. 

Different electrochemical surface treatments have found extensive use for the purposes of providing metal parts with particular properties, appearance, and shape. This includes the apphcation of superficial oxide or salt films (see Section 16.3), metal films (Section 16.5), and a number of methods that exploit the selective anodic dissolution of different segments of the metal surface. We examine briefly a few examples of the latter type. 

Garrido et al. developed an electrochemical procedure for the determination of mefenacet residues in rice crops. Qptimization of parameters such as pH, frequency and electrochemical electrode surface treatment is necessary to obtain accurate analytical data.

Since the CL reaction is being produced by an electrochemical stimulus, greater control is gained over the initiation, rate, and course of the CL reaction. Indeed this control can be to the extent that the CL reaction may be switched on and off, allowing for synchronous detection, effective background correction, and ready automation with computer control. By careful selection of the electrode material, surface treatment, and applied potential, an additional degree of electrochemical selectivity can also be introduced. 

DMFC modeling thus aims to provide a useful tool for the basic understanding of transport and electrochemical phenomena in DMFC and for the optimization of cell design and operating conditions. This modeling is challenging in that it entails the two-phase treatment for both anode and cathode and that both the exact role of the surface treatment in backing layers and the physical processes which control liquid-phase transport are unknown.
