Design of Surface-Supported Bio-inspired Networks for CO2 and O2 Activation at Room Temperature

Daniel Eduardo Hurtado Salinas

The structure of a biological system defines its function. Therefore, nature has developed sophisticated systems that catalyze chemical reactions that are vital for life on earth. For instance, the photosynthesis is a biological process that is partially r ...

Long-lived Photo-Charges in 1D Helical Organic Semiconductor Nanostructures

Regina Judith Hafner

The formation of photoexcited states in organic semiconductors, their separation into long-lived or stable charge carriers, as well as the charge transport are critical processes relevant to several important research fields and emerging technologies. Whil ...

Patterns of Carbon Nanotubes by Flow-Directed Deposition on Substrates with Architectured Topographies

Pedro Miguel Nunes Pereira de Almeida Reis

We develop and perform continuum mechanics simulations of carbon nanotube (CNT) deployment directed by a combination of surface topography and rarefied gas flow. We employ the discrete elastic rods method to model the deposition of CNT as a slender elastic ...

Freestanding Ultrathin Nanoparticle Membranes Assembled at Transient Liquid-Liquid Interfaces

Francesco Stellacci, Stefan Guldin, Zhi Luo, Sergio Allegri, Benjamin Timothée Nicolas Le Ouay

A synthetic route is presented for the realization of ultrathin freestanding nanoparticle membranes that are built of gold nanoparticles protected with trimethoxysilane-bearing ligands. The mechanism relies on interfacial assembly in an oil-water mixture. ...

On-Surface Assembly and Reactions of Organic Molecules in Ultra-High Vacuum

Claudius Morchutt

This thesis comprises the study of two types of 2D materials, those stabilized by non-covalent and those by covalent interactions. They are synthesized and studied on well-defined metallic surfaces in ultra-high vacuum (UHV). The self-assembly of terephtha ...
