Symposium 20 years of nano-optics
various speakers
The field of nano-optics was sparked 20 years ago, when Dieter Pohl and his coworkers at IBM Rüschlikon used light that was forced through a subwavelength opening at the apex of an opaquely coated transparent tip to image subwavelength structures of a sample. Before that time the notion of "near fie ...

Molecular and supramolecular chirality at surfaces
Dr. Roman Fasel
Although the self-organization of chiral molecules into helical architectures is of fundamental importance in nature and for applications in liquid crystal technologies, the mechanism of chirality induction in mesoscopic and macroscopic structures is far from being well understood. A promising appro ...

InAs/GaAs(001) heteroepitaxy: gaining knowledge from first principles
Dr. Evgeni Penev
Self-assembled quantum-dot (QD) heterostructures have already entered
a second decade of intensive and expanding research. Nevertheless both
experimentalists and theorists are still on the way to complete
understanding the intricacies of QD growth kinetics.
In the theoretical "lane", first-principl ...

Nanostructuring using block-copolymers; towards functional surfaces
Dr. Christian Hinderling
Self-assembly of macromolecules is emerging as powerful and flexible method to form organized nanostructures down to dimensions of approximately 10 nm. Block-copolymers; e.g. polymers that contain two or more polymer chains attached at their ends, readily self-assemble to form a rich variety of nano ...

Solvation Forces in Confined Molecular Liquids
Dr. Roderick Lim
Solvation forces in confined liquids have been studied using the atomic force microscope (AFM), and in particular using sample modulation techniques.
Measurements involving liquids of differing molecular structure reveal force oscillations, which agree with computer simulations but can differ marked ...

Self-organized Functional Polymers at Interfaces: Synthesis, Assembly, Surface Characterization and Bio-related Applications
Dr. Marcus Textor
The spontaneous assembly of multifunctional molecules at surfaces has become a useful technique to design hybrid interfaces for the biosensor field, model surfaces for cell-biological studies and drug carrier surfaces for medical application. While alkanethiol self-assembled monolayers on gold surfa ...

The Cu/ZnO catalyst: First-principles studies of surface structures and
Dr. Bernd Meyer
Cu/ZnO based catalysts are widely used on an industrial scale for the synthesis of methanol from H2 and CO/CO2. Nevertheless, the atomic and electronic structure of the nanosized Cu particles supported on ZnO crystallites as well as the origin of the synergistic interaction between Cu and ZnO is poo ...

Ultraminiature mechanical devices for single-molecule and single-quantum nanoscience
Prof. Dr. Michael L. Roukes, Director, Kavli Nanoscience Institute
Advanced techniques in nanoscience now enable the creation of ultrasmall mechanical devices. These nanoelectromechanical systems (NEMS) offer unprecedented opportunities for sensitive chemical, biological, and physical measurements. I will describe three specific applications of NEMS that we are c ...
