Yang 2 Experimental details

Clearly, despite a tremendous body of available literature, the essential details of the mechanism of oxygen reduction on carbon surfaces remain obscure and, unfortunately, even more experimental work will be needed to elucidate it. However, a judicious and yet unexplored guide for future studies is readily available, based on the principle of microscopic reversibility the reaction of carbon surfaces with hydrogen peroxide (in the absence of an electric field). Even a cursory analysis of this arguably fruitful topic is beyond the scope of the present review, however. Suffice it to say that the pH dependence of ORR is of interest. It was studied, for example, by Yang and McCreery [246],... 

The study of helical structures in solution has been given great impetus in recent years by the discovery that such structures contribute markedly to the optical rotatory properties of poljqieptides and proteins (Cohen, 1955 Moffitt, 1956 Moffitt and Yang, 1956). This subject is undergoing very rapid development and continual re-evaluation as more experimental studies are performed. A full discussion of optical rotatory phenomena with these substances is inappropriate in this article, and for further details, the reader is referred to recent reviews (Blout, 1960 Levedahl and James, 1961 Urnes and Doty, 1961). Here a brief summary of the subject must suffice. 

Thus two parallel sets of reactions occur polymer growth and its degradation. As the polymer builds up delocalization also increases, which inhibits the autocatalytic growth of the polymer, and this leads to oxidative degradation of the dimer to quinone. This aspect has been studied in detail by Radhakrishnan and Trivedi [87]. However, the degradation of polymer under these experimental conditions is ruled out. Yang and Bard [93b] have eliminated the possibility of formation of benzidine as a dimer product. 

Figures 2, 3,4, and 5 as weU as Tables 1 and 2 present the successful application of STFT-ICA in identification of the modal parameters of an experimental structure (Fig. 2) and a real-world structure subject to the Northridge Earthquake 1994 (Nagarajaiah and Dharap 2003 Nagarajaiah and Sun 2000, 2001), both of which are highly damped. The details are referred to Yang and Nagarajaiah (2013a).

Figures 7c, 11, 12, and 13 and Table 5 show that SCA works very well even with limited sensors in the three-story experimental structure. Details are referred to Yang and Nagarajaiah (2013c).
