  2. 1. Multiscale Modeling of Interfaces

    Author : Sven Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; misfit; Peierls-Nabarro model; semicoherent interfaces; interfaces; cemented carbides; grain boundaries; microstructure; VN precipitates; density-functional theory;

    Abstract : Understanding strength and stability of interfaces between dissimilar materials or phases is a highly active field of contemporary materials research. Knowledge of interface structure and energetics is important for modeling of complex materials both on a mechanical and thermodynamical level as well as for many functional properties. READ MORE

  4. 2. Materials and interfaces for sustainable organic solar cells

    Author : Qilun Zhang; Mats Fahlman; Xianjie Liu; Ronald Österbacka; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic Solar Cell; Interfaces; Photoelectron Spectroscopy; Natural based materials; Sustainable;

    Abstract : Photovoltaics, the apparatus utilizing green solar power to generate electricity, is one of the efficient measures to the continuously increasing energy demand and exacerbated carbon emission of the human civilization. As a candidate with the potential of providing the cheapest and greenest form of electricity, organic solar cells (OSCs) received tremendous scientific interest, resulting in a significant power conversion efficiency (PCE) boosting to above 19% recently.

  5. 3. Dynamics of Enzymes at Interfaces : Lipase adsorption and mobility on solid surfaces

    Author : Andreas Sonesson; Hjalmar Brismar; Robert Tilton; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biophysics; surface chemistry; diffusion; enzymes; lipases; adsorption; mobility; Physics; Fysik;

    Abstract : This thesis aimed to give more insight in the dynamics of enzymes at interfaces. The adsorption and mobility of adsorbed proteins can e.g. give a better understanding of structure-function properties of interfacially active enzymes. READ MORE

  6. 4. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices

    Author : Tobias Nyberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. READ MORE

  7. 5. Biological membrane interfaces involved in diseases : a biophysical study

    Author : Fredrick Lindström; Gerhard Gröbner; Dick Sandström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid-state NMR; DSC; Amyloid-beta peptide; Nociceptin; DMPC; DMPG; DDAB; peptide-lipid interaction; branched-chain fatty acid.; Biophysical chemistry; Biofysikalisk kemi;

    Abstract : Interactions between peptides and biological lipid membranes play a crucial role in many cellular processes such as in the mechanism behind Alzheimer’s disease where amyloid-beta peptide (Abeta)is thought to be a key component. The initial step of binding between a surface active peptide and its target membrane or membrane receptor can involve a non specific electrostatic association where positively charged amino acid residues and a negatively charged membrane surface interact.
