1. 16. Orthoborate Ionic Liquids for Lubricated Interfaces

   Författare :Mamoun Taher; Robin D. Rogers; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : The lifespan and efficiency of various types of machinery is often limited by the performance of its lubricated interfaces, which are formed by two interacting surfaces and a lubricant that separates the surfaces to decrease friction and wear. There is a constant quest for more efficient lubricants capable of lubricating non-ferrous surfaces. LÄS MER

   Sammanfattning : 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. LÄS MER

5. 19. Theoretical Studies Using Simple Ionic Liquid Models

   Författare :Hongduo Lu; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Room Temperature Ionic Liquids; Coarse-Grained Models; Differential Capacitance; Monte Carlo; Classical Density Functional Theory; Room Temprerature Ionic Luqids; coarse-grained model; differential capacitance; Monte Carlo simulation; Classical Density Functional Theory;

   Sammanfattning : Room Temperature Ionic Liquids (RTILs) are organic salts that melt below 100 degrees Celsius. The advantages of RTILs, such as high ionic concentrations and low melting points, promote several potential applications. For instance, RTILs could be utilized in manufacturing energy storage devices, and as efficient solvents. LÄS MER

7. 20. Modification of Paper into Conductive Substrate for Electronic Functions : Deposition, Characterization and Demonstration

   Författare :Elson Montibon; Magnus Lestelius; Lars Järnström; Jouko Peltonen; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic paper; electroconductive paper; flexible electronics; conducting polymer; ionic liquids; fiber network; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The thesis investigates the modification of paper into an ion- and electron-conductive material, and as a renewable material for electronic device. The study stretches from investigating the interaction between the cellulosic materials and the conducting polymer to demonstrating the performance of the conductive paper by printing the electronic structure on the surface of the conductive paper.
