1. 1. Electronic and Geometric Structure of Phthalocyanines on Metals

   Författare :Masumeh-Nina Shariati; Maria Novella Piancastelli; Carla Puglia; Kajsa Uvdal; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monolayer; multilayer; metal-free phthalocyanine; metal phthalocyanine; interaction; intermolecular; adsorbate-substrate; XPS; XAS; STM; DFT; alkali; metallization;

   Sammanfattning : Adsorption of monolayers and multilayers of metal-free and metal phthalocyanines molecules on metal surfaces has been investigated using complementary microscopic and synchrotron-based spectroscopic techniques. It was observed by STM measurements that at monolayer coverage the adsorption direction of the metal-free phthalocyanine molecules with respect to the gold surface vary as a function of temperature, i.

3. 2. Actuators for autonomous microrobots

   Författare :Niklas Snis; Stefan Johansson; Urban Simu; Alvo Aabloo; Uppsala universitet; []
   Nyckelord :Engineering physics; Locomotion; Microrobot; PZT; P VDF-TrFE ; Autonomous; Multilayer; Actuator; Teknisk fysik;

   Sammanfattning : This thesis presents actuators used in autonomous microsystems. Characteristic for all actuators presented is the low drive voltage and the low power consumption. Different motion mechanisms have been studied and applied in various locomotion modules for microrobots. LÄS MER

4. 3. Fine Scale Microstructures of Josephson Junctions in YBa2Cu3O7-δ Thin Film Structures

   Sammanfattning : This work concerns the microstructure of YBa2Cu3O7-.delta. (YBCO) and other related thin films in multilayer structures, studied by mainly transmission electron microscopy (TEM). LÄS MER

5. 4. 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.

7. 5. Adsorption of biopolymers and their layer-by-layer assemblies on hydrophilic surfaces

   Författare :Maria Lundin; Eva Blomberg; Thomas Arnebrant; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Layer-by-layer; multilayer; adsorption; biopolymers; Chitosan; Heparin; Mucin; Albumin; Lysozyme; β-casein; SDS; QCM-D; Ellipsometri; DPI; TIRF; FRET; SFA; layer structure; solvent content; vertical diffusion; exponential growth; solid-liquid interface; deposition conditions; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. LÄS MER
