The influence of the density of metallic atoms on the formation of supramolecular structures onto Si surface alloys is investigated by scanning tunneling microscopy. Terephthalic acid (TPA) adsorption experiments are performed on the Si(111) alpha- and bet ...
The correct assembly of macromolecular protein complexes such as ribosomes or multisubunit membrane channels is essential for their function. Alterations in the process can lead to disease either by loss of function or by acquisition of toxic function. How ...
The baseplate of phage T4 is an important model system in viral supramolecular assembly. The baseplate consists of six wedges surrounding the central hub. We report the first successful attempt at complete wedge assembly using an in vitro approach based on ...
The self-assembly properties of the proximal p-tert-butylcalix[4]dihydroquinone compound have been studied to investigate the role played by crystallization conditions in driving the formation of a previously reported cubic porous framework. In chloroform ...
Terephthalic acid (TPA) deposited on Si(111)-7 x 7, Si(111)-root 3 x root 3-Ag and Ag(111) has been studied as a model system to understand how much passivated semiconductor surfaces differ from semiconductor and metal surfaces in respect of supramolecular ...
In the framework of this thesis self-assembled supramolecular architectures of several molecular species on crystal metal surfaces are characterized. These investigations combine results obtained by means of scanning tunneling microscopy (STM), scanning tu ...
This thesis deals with the supramolecular organization of chiral aminoacids and dipeptides on metal surfaces. The emergence of homochirality in biomolecular systems is one of the most intriguing open questions of Nature. The self-assembly and amplification ...
The formation of supramolecular structures is a central issue in bio- and nanotechnology and therein plays an important role for many novel developments such as biocompatible materials for integrating living cells or coating for implantable sensing devices ...
Peptide based and peptide hybrid materials represent two interesting and challenging classes of biomaterials. Both classes consist of and contain, respectively, one or more polypeptide blocks, endowing the resulting polymers with enhanced self-assembly pro ...
This thesis deals with the self-organization of individual building blocks, specifically organic molecules and metal atoms, into supramolecular structures on metal surfaces under ultra high vacuum conditions (UHV). Self-organization of supramolecular syste ...
The study of conformational transitions of peptides has obtained considerable attention recently because of their importance as a mol. key event in a variety of degenerative diseases. However, the study of peptide self-assembly into beta-sheets and amyloid ...
