The reason for this poor definition of materials is found in the process of their formation, namely difficult to control polymerization reactions. Such reactions also occur in catalytic reactions with small organic molecules. The nature of carbon deposits therefore reflect all the complexity of the bulk carbon materials One aim of this article is to describe the structural anc chemical complexity of carbon or soot in order tc provide an understanding of the frequently observec complexity of the chemical reactivity (e.g. in reac tivation processes aiming at an oxidative removal o deposits).

EMIRS has been successfully applied to many systems. Briefly it can be mentioned the study of adsorbates at the electrode surface [10], the detection of adsorbed reaction intermediates for the oxidation of small organic molecules [12], and the determination of the water structure in the double layer [13]. However, the potential modulation in EMIRS is its drawback, since it prevents the study of irreversible processes as the system must return to the same conditions each time the potential is changed. Other important limitations of EMIRS are related to both the electrical and chemical relaxation effects caused by the potential modulation at 12 Hz. The electrical relaxation is due to the high ohmic drop of the electrolyte confined in the thin solution layer required for the in situ measurements. The chemical relaxation is due to ion migration induced by the change in solution composition caused by the electrode potential change. These aspects have been discussed in detail in the following text [14-16] (see Sect. 3.4.2.3). 

In this chapter, we reviewed current progress in the use of Ti-conjugated polymer as dye polymeric materials in DSSCs. Contrary to the metal complexes or small organic molecule-based dyes, interfacial issues of mesoporous Ti02/sensitizer are more critical and strongly influence the PV performance of devices as well as their stability. The conception of new polymeric dyes and their chemical molecular engineering primarily focuses on the delicate balance of HOMO-LUMO energy levels/interface effect in absorption with photosensitizer/infiltration into the mesoporous metal oxide... 

In the past decades, a significant number of fundamental investigations have been carried out in the field of low-temperature electrooxidation of small organic molecules [14-38]. Electrochemical studies have been carried out in combination with spectroscopy [21,27,28], mass spectroscopy [25,31], physio-chemical tools [20,30], as well as theoretical calculations (e.g., DFT) [38] in order to examine the adsorbed species and reactive intermediates on the electrode surface during the alcohol oxidation, and thus to elucidate the alcohol reaction pathways. 

The efficacy of chemical and photochemical decolourization of dyes in the effluent of textile factories has been proved many times. However, in the majority of cases these methods are relatively expensive and the solid catalysator used for the oxidation sometimes presents a new problem for environmental protection. Microbiological methods are less expensive, the dyes are decomposed to small organic and inorganic molecules which can be taken up by micro-organisms as carbon and nitrogen sources. Also, in the case of microbiological decomposition of dyes, liquid chromatographic techniques can be...
