This thesis presents the first total synthesis of all possible stereoisomers of plakortide E and also confirms the absolute configuration of natural plakortide E. It also details a biomimetic method for converting Plakortide E methyl ester to plakortone B.

In this thesis, Claudia Backes guides the reader through her multidisciplinary research into the non-covalent functionalization of carbon nanotubes in water. Although one of the most remarkable materials of the 21st century, carbon nanotubes often have limited application because of their intrinsically low solubility and polydispersity. The author shows that rational surfactant design is a powerful tool for chemists because it can unmask the key to solubilization and allow us to tailor nanotube surface and optical properties in a fully reversible fashion. Aspects of organic, physical and...

Empirical research needs a profound theory to be successful. This is the simple but, in its consequences, radical approach for this study in geomorphology. It critically analyses the current system understanding and offers a new view for a geomorphology that understands systems as being open but at the same time operationally closed, as self-organized, structure-building and potentially self-referential. Kirsten von Elverfeldt succeeds in designing a theoretical framework that sets new standards within Physical Geography. By using state-of-the-art concepts in system theory, it offers also...

Electric control of magnetic properties, or inversely, magnetic control of dielectric properties in solids, is called a magnetoelectric effect and has long been investigated from the point of view of both fundamental physics and potential application. Magnetic and dielectric properties usually show minimal coupling, but it recently has been discovered that magnetically induced ferroelectricity in some spiral magnets enables remarkably large and versatile magnetoelectric responses. To stabilize such helimagnetism, magnetic frustration (competition between different magnetic interactions) is...

A major problem in physics is understanding the nature of the dark energy that is driving the accelerating expansion of the universe. This thesis demonstrates that the interpretation of future galaxy survey measurements is far more subtle than is widely assumed, and that a major revision to our models of the effects is urgently needed.

Common methods of local magnetic imaging display either a high spatial resolution and relatively poor field sensitivity (MFM, Lorentz microscopy), or a relatively high field sensitivity but limited spatial resolution (scanning SQUID microscopy). Since the magnetic field of a nanoparticle or nanostructure decays rapidly with distance from the structure, the achievable spatial resolution is ultimately limited by the probe-sample separation. This thesis presents a novel method for fabricating the smallest superconducting quantum interference device (SQUID) that resides on the apex of a very...

Manuela Mura's thesis is devoted to ab initio studies of self-assembled organic molecules on a gold surface. This area of research is particularly vibrant because of the various applications such studies have in nanoscience and surface chemistry and physics. In this thesis Manuela Mura uses theory to suggest atomistic models for the observed assembled and she proposes an assembly mechanism. The methods and results developed as part of this work will be of wide interest to physicists and chemists working on the assemblies of organic molecules on crystal surfaces.

Motivated by the discovery of intriguing effects that arise when electromagnetic radiation interacts with metallic nanostructures, this book focuses on fabrication of extended-area plasmonic nanostructures, and the optimization of their optical response.

With a length of about 1200 km, the Son-Narmada-Tapti Lineament (NSL) is one of the most prominent geomorphic features in the Indian subcontinent. Anomalous conductive bodies are delineated at mid-lower crustal depths below major earthquake epicentral zones. The region has been interpreted as the collision zone of the Indian Plate with the Eurasian Plate. The NSL zone is therefore also known to be the second most important tectonic feature in the Indian geology, after the Himalayas. The present thesis describes significant new insight into the seismotectonics of this Central India...
