报告人简介:
Prof. Harald Fuchs received his PhD in theoretical physics from the University Saarbruecken (Germany) in 1977, and became a postdoctoral researcher in G.Binnig and H. Rohrer (Nobel Prize in Physics in 1986)’s STM group at IBM Rueschlikon in 1984. After that he moved to BASF AG as a project manager working on ultrathin organic films and introducing STM to the chemical industry. He began to work in University of Muenster since 1993, and became a Full Professor of Physics, and the Director of Physical Institute. He was the Co-founder of the Center for Nanotechnology (CeNTech) in Muenster, and became its Scientific Director in 2003. He has been the member of the Institute for Nanotechnology (INT), FZ-Karlsruhe since 2004. He was awarded with several research prizes. He is an elected member of the German National Academy of Science ‘Leopoldina’, the German National Academy of Science and Engineering 'acatech', and the 'TWAS'.
报告摘要:
The formation of chemical bonds depends strongly on the spatio-temporal conditions within an ensemble of starting molecules. We found that by using nanostructured surfaces on metallic single crystals, a significant increase of the reaction rate can be obtained, even with simple linear hydrocarbons exhibiting very poor chemical reactivity. By imposing appropriate self-organized nano-confinements on the metallic surface which promote heterogeneous catalysis, polymerization of the linear monomeric units at mild conditions is obtained via CH-activation. The concept can be extended, for example, to 2-dimensional Glaser-coupling reactions on low indexed surfaces. The examples presented demonstrate new pathways to generate specific chemical bond formation which is unlikely to occur with conventional chemical techniques. In the second part of the talk a novel approach for preparing a multimode near field optical probe the generation of biomimetic systems using Dip Pen Nanolithography (DPN) will be discussed. The latter allows us to write chemical diverse small structures for the interaction with biological systems such as biological cells. Recent developments and perspectives for the generation of biomimetic surfaces and sensor applications will be presented.
