The photocatalytic mineralization of phenol in aqueous solutions under various experimental conditions was employed, to test the activity of the prepared immobilized fibreglass/TiO2 photocatalysts. The particles of titanium dioxide P25 were coated on the surface of commercial fibreglass fabric by dipping in ethanolic TiO2 suspensions and were fixed by firing 6 h at 500 °C.

Oxidizing Agent

Phenol and its derivatives constitutes one of the most dangerous groups of organic chemicals which can cause many environmental and health risks. Therefore removal and degradation of phenol from aqueous solutions is one of the great industrial importance. Ozone is considered to be one of the most effective oxidizing agent for phenol degradation.. The objectives of this study are to examine the roles of added catalyst to rapid the process of phenol degradation by ozone.

Ultrathin Frozen Sections

During the last years it was shown that also by means of cryo-ultra-microtomy a good preservation of substructural details of biological material was possible. However the specimen generally was prefixed in these cases with aldehydes.Preparing ultrathin frozen sections of chemically non-prefixed material commonly was linked up to considerable technical and manual expense and the results were not always satisfying. Furthermore, it seems to be impossible to carry out cytochemical investigations by means of treating sections of unfixed biological material with aqueous solutions.We therefore tried to overcome these difficulties by preparing yeast cells (S. cerevisiae) in the following manner:
