Lange erwartet, jetzt ist es da: ein Buch, das die Prinzipien der Rheologie konsequent auf Dispersionen anwendet. Der praxisorientierte Titel hilft Chemikern und Chemieingenieuren, disperse Systeme zu formulieren und zu optimieren und dabei viel Zeit und Mittel zu sparen.
Tharwat F. Tadros was appointed lecturer in Physical Chemsitry (1962-1966) at Alexandria University. Between 1966 and 1969, he spent a sabbatical at the Agricultural University of Wageningen and T.N.O. in Delft, The Netherlands. Thereafter he joined I.C.I. and ZENECA until 1994, where he researched various fields of surfactants, emulsions, suspensions, microemulsions, wetting spreading & adhesion and rheology. During that period he was also appointed visiting professor at Imperial College London, Bristol University and Reading University. In 1992, he was elected President of the International Association of Colloid and Interface Science. Since leaving ZENECA, Tharwat F. Tadros has worked as a consultant for various industries and also given several courses in his specialized field. He is the recipient of two medals from the Royal Society of Chemistry in the UK, and has more than 250 scientific papers to his name.
