1. Reactive Sputtering of Cubic-Phase BN:C and Nanostructured B-N-C Films : Growth, Microstructure, and Mechanical Properties
Abstract : Synthesis, structure, and mechanical property related issues in the carbon-containing boron nitride (BN:C) system have been studied. Magnetron sputtering, comprising a B4C target in mixed Ar-N2 discharges and deposition parameters of low ion energy, high ion-to-neutral flux ratio, and substrate temperatures ... READ MORE

2. Boron Suboxide Based Thin Films
Abstract : Boron suboxide (BOx, x< 1.5) is a promising material for a wide range of applications. The elastic modulus (E) of 473 GPa has been reported for crystalline BO0.17, which tends to exhibit ultra-low friction as a direct consequence of boric acid (H3BO3) formation. READ MORE

3. Relating the Bulk and Interface Structure of Hyaluronan to Physical Properties of Future Biomaterials
Abstract : This dissertation describes a structural investigation of hyaluronan (HA) with neutron scattering techniques. HA is a natural biopolymer and one of the major components of the extracellular matrix, synovial fluid, and vitreous humor. READ MORE

4. Magnetically governed self-assembly of soft matter : A look into interfacial layering, crystallization and percolation
Abstract : Self-organisation is the key route for assembling colloidal particles into well-defined structures. Decisive for this are the interactions between the constituents, which are amongst others steric, electrostatic or magnetic. READ MORE

5. Tailing Charges on New Paths : Ultrafast intramolecular charge transfer in chromophores
Abstract : By tailing charges on their paths within a molecule, one can gain fundamental knowledge of their inherent reactivity. The charges, originally residing in their lowest energy configuration, can upon light absorption move across the system, or transfer in between them. READ MORE
