1. 11. Optics and Instrumentation for Compact Soft X-Ray Microscopy

   Författare :Göran Johansson; KTH; []
   Nyckelord :x-ray; multilayer; optics; microscopy;

   Sammanfattning : This thesis describes thedevelopment of soft x-ray reflective optics and instrumentationfor compact soft x-ray microscopy. This microscope operates atthe wavelength 3.374 nm in the water-window (2.3 - 4. LÄS MER

3. 12. Interactions of Mucins with Biopolymers and Drug Delivery Particles

   Författare :Olof Svensson; Malmö högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mucin; chitosan; lactoperoxidase; multilayer; mucoadhesion; nanoparticles; ellipsometry;

   Sammanfattning : The main components in the mucous gels apart from water are mucins, which are proteins with high molecular weights and an abundance of negatively charged oligosaccharide side chains. The aim of the investigations was to characterize interactions between mucins and other proteins that are present in the mucous gel, and also between mucins and components used in pharmaceutical formulations.
