New Strategies in Chemical Synthesis and Catalysis (eBook)

Bruno Pignataro, born in Bologna in 1972, is Professor of Physical Chemistry at the University of Palermo. He received his degree in chemistry in 1995 from the University of Catania and his PhD in materials science five years later. He has helped establish a wide network of international collaborations and organized several scientific activities at national and international level, including coordinating the Young Chemists Group of the Italian Chemical Society and chairing the first three editions of the European Young Chemist Award. Professor Pignataro's group research focus on the fields of nanoscience and nanotechnology, molecular electronics, and biotechnology.
