1. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes
Master-uppsats, KTH/Tillämpad fysikalisk kemiSammanfattning : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. LÄS MER
2. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER
3. Molecular Insights into the Interactions of Monovalent Cations with Highly charged Fatty Acid Monolayers
Master-uppsats, KTH/KemiSammanfattning : Vibrational sum frequency spectroscopy har använts för att studera interaktionerna mellan monovalenta joner och laddade fettsyramonolager. Subfasen bestod av utvalda alkalihydroxidsaltlösningar med pH12, med huvudfokus på cesiumjonen. LÄS MER
4. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. LÄS MER
5. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.
