   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquids; electrical double layer; self-assembly; electro-interfacial structure; tribotronics; supercapacitors; friction; lubrication; Jonvätskor; elektriskt dubbelskikt; självassociering; gränsskiktselektrostruktur; tribotronik; superkondensatorer; friktion; smörjning; Kemi; Chemistry;

   Abstract : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. READ MORE

4. 2. Structure formation at solid/liquid interfaces : Understanding self-assembly and environmental challenges

   Author : Shirin Nouhi; Adrian R. Rennie; Vassilios Kapaklis; Maja S. Hellsing; Ann Terry; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid liquid interface; neutron scattering; colloidal particles; self-assembly; perfluoroalkyl substance; Moringa seed proteins; adsorption; lamellar disorder; thermal fluctuations.;

   Abstract : The work described in the present dissertation has explored the structure of particles and molecules at solid/liquid interfaces, aiming to understand the physics of self-organizing systems and use this knowledge to address some environmental issues. Surface-sensitive neutron scattering techniques, such as reflectometry and grazing incidence small angle scattering, have been used as the primary tool to investigate structures in proximity to an interface.

5. 3. Nanoparticle Self-assembly on Prefabricated Nano Strucutres

   Author : Johnas Eklöf; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofabrication; Nanoparticles; single molecular electronics; Self-assembly;

   Abstract : The demand for more powerful computers have been increasing ever since the first semiconducting devices were invented in the second half of the 20th century. The demand for an increase in computing power have escalated since the start of modern computer technology, however conventional techniques are reaching the limits regarding the downscaling of semiconducting based logic circuits.

6. 4. Self-assembly Strategies for Functional DNA Nanostructures

   Author : John Tumpane; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; polarised spectroscopy; nanotechnology; self-assembly; orientation; lipid membrane; gel electrophoresis; DNA;

   Abstract : The technological revolution of the twentieth century was famously subject to Moore’s law which related the rate of growth to the ability to scale-down the size of the components – size matters. Several decades later we are, however, approaching the limit of what is possible with silicon wafers. READ MORE

7. 5. Molecular Electronics - Modeling, Devices and Architecture

   Abstract : Molecular electronics is an area of micro/nanoelectronics with a number of farreaching goals and challenges: denser implementation of electronic memory and logic, less expensive manufacturing, smaller or more sensitive measurement devices, selfassembly of devices and systems and, last but not least, exploring new science and applications.In recent years, molecular electronics has expanded into a broader field of molecular-scale electronics, partly because molecular components have to be defined in solid-state contexts via lithography and self-assembly, and effectively become hybrid devices with new and interesting properties.
