   Abstract : This thesis introduces new ways to produce micro-and nanostructures of recombinant spider silk and explores ways to characterize their topography, mechanical properties, cell compatibility, and permeability. The suitability of the formed structures for applications within tissue engineering, primarily in vitro tissue modeling, is also investigated. READ MORE

4. 2. Study of GaN Based Nanostructures and Hybrids

   Author : Mathias Forsberg; Galia Pozina; Ching-Lien Hsiao; Kevin P. O'Donnell; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sputtering; Forster; Semiconductor; Nitride; GaN; Hybrid; Nanorods; Nanostructure; Thin film; Förstoffning; Sputtring; Förster; Halvledare; Nitrid; GaN; Hybrider; Nanostavar; Nanostrukturer; tunnfilmer;

   Abstract : GaN and its alloys with Al and In belong to the group III nitride semiconductors and are today the materials of choice for efficient white light emitting diodes (LEDs) enabling energy saving solid state lighting. Currently, there is a great interest in the development of novel inexpensive techniques to fabricate hybrid LEDs combining high quality III-N quantum well (QW) structures with inexpensive colloidal nanoparticles or conjugated polymers.

   Author : Milton Persson; Vladislav Korenivski; David B. Haviland; Coriolan Tiusan; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spin vortex pairs; bimerons; RKKY; finite size effects; nanostructure magnetocalorics; atomistic spin dynamics; nanocalorimetry; Spinvirvelpar; bimeron; RKKY; finita storlekseffekter; magnetkalorimetri i nanostrukturer; atomistisk spindynamik; nanokalorimetri; Material and Nano Physics; Material- och nanofysik;

   Abstract : In this thesis we study strongly coupled pairs of spin vortices, in a configurationsuch that the cores attract while external fields act to pull them apart, with potential applications in magnetic random access memory (MRAM) and oscillators.Inertial decoupling of the cores has been studied and can be achieved with weak nanosecond pulses by the help of anharmonicity.

6. 4. Design, Synthesis and Characterization of Nanostructured Thermoelectric Materials

   Author : Bejan Hamawandi; Muhammet Toprak; MARISOL Martin Gonzalez; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Material and Nano Physics; Material- och nanofysik; Fysik; Physics;

   Abstract : The demand for energy is rapidly increasing, triggering more carbon emission and global warming. Alternative green energy sources are essential to secure the future generation from the effect of pollution and global warming. READ MORE

7. 5. Photoemission Electron Microscopy for Ultrafast Nano-Optics - Femtoseconds to Attoseconds

   Author : Erik Mårsell; Synkrotronljusfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanorice; Spatiotemporal imaging; Attosecond pulses; Fysicumarkivet A:2016:Mårsell; Nanowires; Silver nanostructures; Femtosecond laser pulses; PEEM; Plasmonics; Ultrafast nano-optics;

   Abstract : Ultrafast nano-optics is a new and quickly evolving research field centred around the control, manipulation, and application of light on a nanometre and femtosecond scale. This can lead to improved electro-optical devices, more sensitive spectroscopy, and real-time control of chemical reactions. READ MORE
